The ceramic rubber composite board can be divided into two types, one is a two-in-one ceramic and rubber lining board, which adopts the rubber thermal vulcanization method to vulcanize the ceramic and the rubber together, and then paste it on the equipment with a professional adhesive to form a Wear-resistant layer with a certain cushioning force.   The ceramic rubber composite plate combines the advantages of high hardness and wear resistance of ceramics and high toughness of rubber, which can effectively decompose the impact force of materials on the lining plate. It is very suitable for anti-wear equipment that needs to withstand large impact forces, such as sintering systems, hoppers, silos, and other parts of steel plants with high drop and high impact.    There is also a three-in-one, which is a combination of ceramics, rubber, and steel plates. This three-in-one composite board can be connected by welding and bolts, while the two-in-one can only be connected by gluing. See which one is suitable for the equipment conditions.   The ceramic rubber composite board has a good buffering effect, which can effectively buffer the impact force of materials such as ore falling from a high altitude. The construction is convenient, the ceramic rubber composite lining can be twisted and cut, and it is suitable for installing various special-shaped equipment. No sticking and no blocking. Due to the wear and corrosion resistance of ceramics, the phenomenon of equipment sticking and blocking can be solved.   The ceramic rubber composite plate has high wear resistance, and high impact resistance, does not need to be replaced frequently, has a long service life, and effectively saves the cost of enterprises.

Wear-resistant ceramic pipe full name metal ceramic lined composite pipe. The wear-resistant ceramic tube is manufactured by high-tech production technology - self - droning high - temperature clutch synthesis method. The tube is composed of corundum ceramic, a transition layer, and a steel layer from inside to outside. The ceramic layer forms dense corundum porcelain (AL2O3) at a high temperature above 2200℃ and forms a firm bond with the steel pipe through the transition layer. Advantages Because the composite pipe gives full play to the steel pipe high strength, good toughness, impact resistance, good welding performance, and corundum porcelain high hardness, high wear resistance, corrosion resistance, and good heat resistance, overcome the characteristics of steel pipe low hardness, poor wear resistance, and ceramics poor toughness. Therefore, the composite pipe has good wear resistance, heat resistance, corrosion resistance, mechanical impact and thermal impact resistance, good weldability, and other comprehensive properties. It is an ideal wear-resistant and corrosion-resistant pipeline for conveying granular materials, grinding, and corrosive media. Widely used in electric power, mining, steel, cement, chemical, and other wear industries. Model straight pipe, elbow, bend, tee, size head, in addition to the production of pants pipe, the use of the effect is very ideal. Can replace alloy pipe, cast iron, and so on. application Because the pipe has wear resistance, corrosion resistance, and heat resistance, so it can be widely used in electric power, metallurgy, mining, coal, chemical industry, and other industries such as the transport of sand, stone, coal powder, ash, liquid aluminum grinding granular materials and corrosive media, is an ideal corrosion resistance pipeline. Application in metallurgy and electric power industry Metallurgy, the electric power industry transport coal powder, ash, mud, lime gypsum slurry, and other annual consumption of a large number of metal pipes. The ceramic composite pipe is used instead of other pipes, which has the characteristics of high wear resistance, long service life, easy installation, and remarkable economic benefits. By Shandong liaocheng chang embellish thermal power plant, liaocheng power plant, Beijing northern new building materials group, Henan hebi power plant, Gansu of our power plant, Taiyuan coal preparation plant, Hunan shaman power plant, Hebei jinni energy co., LTD shotcrete-bolt coal preparation plant, xingtai coal preparation plant and other industrial operation, its operation life is more than a dozen times and even more steel pipe. Application in the mining and coal industry (1) Mine: mine filling, refined ore powder, and tailings transport wear on the pipeline are serious, the service life of the previously used ore powder transport pipeline such as Panzhihua, Daye mine, etc. is less than one year, and the service life of the pipeline can be increased by about 5 times. (2) Coal: coal preparation and long-distance pipeline coal transport are commonly used for wet conveying, the conveying pipe is wear-resistant and corrosion-resistant, and the pipe can be used as a long-life conveying pipe, with considerable economic benefits. other (1) The tube does not pollute and does not stick to the fused aluminum liquid. It IS IDEAL TO MANUFACTURE ALUMINUM MELTING EQUIPMENT, aluminum liquid CONVEYING PIPE and liquid RISER PIPE, which IS sensitive to IRON pollution and needs heavy labor for finishing and maintenance after use. (2) The tube due to good wear resistance and heat corrosion. It is suitable for conveying corrosive materials containing solid particles, high temperature corrosive gases, sulfur-containing geothermal water and other corrosive media. Product features editor broadcast SHS- self - tendered ceramic composite pipe features Good abrasion resistance As the lining layer of ceramic composite pipe is corundum ceramic (a-AL2O3), the Mohs hardness can reach 9.0, equivalent to HRC90 or more. Therefore, it has high wear resistance to the grinding media transported in metallurgy, electric power, mining, coal and other industries. The industrial operation proved that its wear-resistant life is ten times or even dozens of times of quenched steel. Low running resistance SHS ceramic composite pipe does not have a convex helix on the inner surface of seamless steel pipe because its inner surface is smooth and never corrodes. The INNER SURFACE ROUGHNESS AND water resistance characteristics of the relevant testing unit test, its inner surface smoothness is better than any metal pipe, clear resistance coefficient of 0.0193, slightly lower than seamless pipe. Therefore, the tube has the characteristics of low running resistance and can reduce the running cost. Corrosion resistance, anti-scaling Because the steel ceramic layer is (a-AL2O3), it is neutral. Therefore, it has acid and alkali resistance and seawater corrosion resistance and has the characteristics of scale prevention. Fou has good performance in temperature resistance and heat resistance Because the corundum ceramic (A-al2o3) is a single stable crystalline structure. Therefore, the composite pipe can operate normally in the temperature range of -50--700℃ for a long time. The linear expansion coefficient of the material is 6-8×10-6/0C, which is about 1/2 of that of steel pipe. The material has good thermal stability. Low project cost Ceramic-composite pipe is lightweight, and the price is suitable. It is 50% lighter than the cast stone pipe with the same inner diameter; It is 20-30% lighter than wear-resisting alloy tube, and has good wear-resisting and corrosion resistance, because of its long service life, to reduce the cost of support and hanger, handling cost, installation cost and operation cost. The project cost of the pipe is comparable to that of cast stone, and compared with the wear-resistant alloy pipe, the project cost is reduced by about 20%. Easy installation and construction Due to the light weight of the tube, and good welding performance. Therefore, welding, flange, rapid connection, and other ways can be used to facilitate the construction and installation and reduce the installation cost. species Centrifugal cast composite ceramic pipe Centrifugal CASTING COMPOSITE CERAMIC PIPELINE IS A COMPOSITE PIPE MANUFACTURED by "SELF-tenDRoning HIGH-TEMPERATURE SYNTHESIS-HIGH SPEED CENTRIFUGATION TECHNOLOGY", which forms a uniform, compact, and smooth ceramic layer and transition layer at high temperature and high speed. Laminated wear-resistant ceramic piping The veneer wear-resistant ceramic pipeline is made of alumina ceramic pieces pasted on the inner wall of the pipeline with high temperature resistant strong adhesive, which forms a firm anti-wear layer after heating and curing. The production process is simple and the cost is high. The service temperature generally can not exceed 100 degrees, not suitable for pipes. Spot welded card-type wear-resistant ceramic piping Spot welding card type wear-resisting ceramic pipeline uses high temperature resistant strong adhesive to paste the alumina ceramic sheet with a hole in the middle of the pipeline wall, while with spot welding process through the hole will be firmly welded ceramic in the inner wall of the steel pipe. To protect the solder joint, a ceramic cap is mounted on it. Each piece of porcelain is not only inserted into each other but also forms a trapezoidal Angle, so that the porcelain is closely connected between the pieces, with no gap; When the last piece of the circle is tightly embedded, the pieces form a 360-degree mechanical self-locking force between themselves (a technique that was used in Chinese bridge construction centuries ago). The production process of this kind of product is relatively complex, the production cycle is long, and the cost is high. Integrated molding wear-resistant ceramic pipeline Integrated molding is the ceramic pipe fittings fired as a whole, with special filling material poured into the inner assembly of the steel pipe. The inner wall of the pipeline is smooth, good sealing, good wear resistance, and corrosion resistance. Ceramic-lined composite steel pipe. Ceramic steel pipe and traditional steel pipe, wear-resistant alloy cast steel pipe, cast stone pipe and steel plastic, and steel rubber pipe have essential differences. Ceramic steel pipe outer steel pipe, inner corundum. The corundum layer has a Vickers hardness of 100 -- 1500 (Rockwell hardness of 90 -- 98), equivalent to tungsten and cobalt hard gold. The wear resistance is more than 20 times higher than that of carbon steel tubes, and its performance is much better than that of commonly bonded corundum grinding wheels. The corundum grinding wheel is still the main grinding wheel for all kinds of grinders cutting hardened steel. The corundum layer in the ceramic steel tube can wear away the corundum grinding wheel. Ceramic steel pipe wear resistance mainly depends on the inner layer of a few millimeters of corundum layer, its Mohs hardness of 9, second only to diamond and silicon carbide, in all oxides, its hardness is the highest.   Ceramic wear-resistant steel tube lined with ceramic is made by self-spreading high-temperature synthesis -- centrifuging method. The melting point of corundum in a ceramic steel tube is 2045℃. The corundum layer and steel layer have special structures and special stress fields due to technological reasons. Under normal temperatures, the ceramic layer is under compressive stress, and the steel layer is under tensile stress. The two are opposites and unity, forming a balanced whole. Only when the temperature rises above 400℃, the new stress field generated by thermal expansion and the original stress field in the ceramic steel tube cancel each other due to their different thermal expansion coefficients, so that the ceramic layer and the steel layer are in free equilibrium. When the temperature rises to 900℃ to put the lining ceramic wear-resistant steel pipe in cold water, and repeatedly soak many times, the composite layer does not crack or crack, showing the incomparable thermal impact resistance of ordinary ceramics. This performance is of great use in engineering construction because its outer layer is steel, coupled with the inner layer heating does not crack, in the construction, the flange, purging mouth, and explosion-proof door can be welded, and can also be connected by direct welding method, This is better than wear-resistant cast stone pipe, wear-resistant cast steel pipe, rare earth wear-resistant steel pipe, bimetal composite pipe, steel plastic pipe, steel rubber pipe in the construction is not easy to welding or welding. The INNER CERAMIC WEAR-RESISTANT STEEL TUBE has good mechanical impact resistance, and the composite layer does not break and fall off during transportation, installation knocking and bending deformation of the dead weight between the two supports.   The practice of dozens of thermal power plants shows that: lined ceramic wear-resistant steel pipe has high wear resistance and strong fluid erosion resistance. In the primary air duct, the wear resistance of the curved pipe is the fastest, and the wear resistance of the curved pipe lined with ceramic wear-resisting steel pipe is more than 5 times higher than that of the wear-resisting cast steel pipe with a thick wall. In practice, lined ceramic wear-resistant steel pipe used 1-2 years after opening observation and measurement, the composite layer has no obvious wear or fall off, in the same specifications and unit length of the pipeline, the weight of lined ceramic wear-resistant steel pipe is only about 1/2 of the wear-resistant cast steel pipe or bimetal composite pipe, its per meter project cost is reduced by 30-40%. Only cast stone pipe and rare earth wear-resistant steel pipe weight of about 2/5, per meter project cost reduced by more than 20%. In corrosive or high-temperature places under the use of lined ceramic wear-resistant steel pipe, its price is only stainless steel pipe, nickel-titanium pipe of a fraction of. Fluid pipeline transportation is not only used in the electric power industry but also throughout metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries. When the pipeline conveys grinding material (such as ash, coal powder, mineral powder, tailings, cement, etc.), there is a problem of fast pipeline wear, especially the fast wear of the elbow; When the pipeline is transported with strong corrosive gas, liquid or solid, there is a problem that the pipeline is corroded and thus destroyed quickly; When the material with high temperature is transported in the pipeline, the use of heat-resistant steel pipe is very expensive and so on. With the introduction of ceramic lined wear-resistant steel pipe, these problems can be solved easily.  

The wear-resistant ceramic fan volute is a wear-resistant ceramic sheet attached to the working surface such as the arc plate and side plate of the fan volute to form a surface layer with excellent wear resistance, which can increase the wear-resistant service life of the fan volute by at least more than ten times. The Mohs hardness of the wear-resistant ceramic sheet is 9, second only to diamond, and the self-abrasion is 1.5‱, which is very suitable for the anti-wear treatment of the fan volute.    In the construction process of wear-resistant ceramics, various problems will occur. Among them, as far as the fan volute is concerned, the problem of large-area shedding of wear-resistant ceramic sheets is prone to occur. In response to this problem, the following points should be paid attention to: 1. Before sticking, be sure to sandblast the fan volute, polish, remove rust and oil, and clean it with 99% acetone if there is oil. 2. When the ambient temperature is higher than 150 degrees, use high-temperature glue, and when the normal temperature is 100 degrees, use ordinary glue. 3. The ratio of glue, mix thoroughly according to the ratio of 4:1, apply it to the surface of the object to have adhered, close the wear-resistant ceramic sheet, and tap it with a rubber hammer. 4. After curing at room temperature for 8 hours, you can tap it with a small hammer to see if there is any lack of glue. If there is, it should be pasted again.   The installation of wear-resistant ceramics mostly uses strong adhesive to paste the wear-resistant ceramics on the surface of the mechanical spare parts. After the wear-resistant ceramics are installed by sticking, they can ensure long-term work without falling off, and can effectively protect the mechanical spare parts. When the working temperature of the equipment is high, the wear-resistant ceramic and metal can be compounded together by inlay technology, and flexible compounding technology can be adopted according to the working environment of the equipment, which can reduce the investment cost for customers to the greatest extent based on improving the wear resistance of the equipment.

Equipment wear and tear is a problem that all factories need to face, and the quality of the anti-wear treatment of the equipment will directly affect the production efficiency and personnel safety of the company. Types of equipment wear, analysis of factors affecting equipment wear and selection of anti-wear materials, etc.   Definition of wear type: Abrasive wear (also known as abrasive wear or sliding wear) refers to the friction caused by the extrusion of hard particles or hard asperities on the surface of the friction pair to the solid surface and the relative movement along the surface. A very common form of wear and tear due to loss or loss of material;   Impact wear: refers to the phenomenon that the material hits the surface of the material with a certain speed under the action of gravity or centrifugal force, resulting in local material loss or peeling;   Corrosion wear: During the friction process, the metal reacts chemically or electrochemically with the surrounding medium at the same time, causing corrosion and wear to work together to cause the loss of surface materials of parts. This phenomenon is called corrosion wear. Factors affecting equipment wear: The wall thickness of the worn part of the equipment is the main influencing factor. The thicker the wall thickness, the harder it is to wear; The type and hardness of the material, in general, the wear intensity of solid is greater than that of liquid and gas, the greater the hardness, the greater the wear intensity; The sharper the shape of the material, the easier it is to wear the surface of the equipment; Whether the material is chemically aggressive; External environmental humidity, flow rate, drop height, etc.;   Selection of anti-wear materials: Selection of anti-wear materials: The cost-effective wear-resistant material-alumina wear-resistant ceramics Wear-resistant material suitable for very severely worn parts - ZTA zirconia ceramics The high hardness of ceramics and the high toughness of steel are fully combined, suitable for parts with large impact wear-alloy ceramics Wear-resistant ceramic material is suitable for anti-wear in high-temperature environments - high-temperature ceramic.   http://www.ybnceramic.com/alumina-ceramic-liner/impact-resistant-linings.html

The interior of the vertical mill is located at the air outlet, and the wear is particularly serious, and the position where the wear is more serious is located below 1-1.5 meters from the barrel of the coal mill. Generally, 20mm thick ceramic welding plates or 70*70* (20+5) are used. Hemispherical ceramic welded plate, the hemispherical design can play a certain impact resistance. Use 5mm ceramic sheets or 10mm studs to weld ceramic linings at positions above 1-1.5 meters of the cylinder.   Because the top of the coal mill is not easy to construct, both the stud welding lining plate and the ceramic sheet can be used, and room-temperature glue can be used. Most of the separators use 5-10mm ceramic sheets. Both the welded ceramic lining plate and the ceramic sheet can be used for the inner supporting steel frame of the coal mill.    Weldable impact-resistant ceramic liner is developed based on our many years of work and experience. The ceramic adopts a unique formula of 95% Al2O3 adding a variety of wear-resistant materials. It is dry-pressed and has high density, high toughness, and wear resistance. Features.   The wear resistance of the weldable impact-resistant ceramic liner produced by our company is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.   Wear-resistant ceramic lining plate is a wear-resistant, impact-resistant, and corrosion-resistant material for industrial use. The thermal expansion coefficient of viscose is between steel and ceramics, which can well adjust the extrusion of ceramics due to the inconsistency of thermal expansion between ceramics and steel. ; At the same time, a variety of flexible fibers are added to the adhesive to maximize the long-term operation of the ceramic in the vibration, thermal expansion, and cold contraction environment without falling off.      

The charge must be equipped with wear-resistant ceramic linings at the blanking points and material flow rubbing points of the charging strip on the top of the bell furnace. The working conditions of the wear-resistant ceramic linings determine their high-temperature resistance, wear resistance, and the performance requirements of impact resistance, high-temperature resistance, wear resistance, and impact resistance the wear-resistant ceramic liner determines its service life, and its service life is directly related to the reliability of the furnace top charging equipment, which directly affects the blast furnace. Stabilizing the production cycle is also closely related to the blast furnace shutdown rate and the economic loss of the iron smelting plant.   The wear-resistant ceramic lining plate is made of aluminum oxide as the main raw material and rare metal oxides as the flux. After melting at a high temperature of 1700 ° C, it is combined with special rubber and high-strength organic adhesives. It can also be used alone. Ceramic backing plate as lining. The wear-resistant ceramic lining plate has high hardness, the Rockwell hardness is 80-90, which is higher than that of minerals such as ore and coal ash; the wear resistance is strong, the wear resistance is 266 times that of the steel plate, the density is small and easy to process, and the rubber Vulcanized together can be cut, twisted and assembled, not limited by the shape, size, and installation position of the equipment.   The wear-resistant ceramic lining plate is used as the lining plate of the blast furnace charging the car, which reduces the wear and tear of the equipment, improves the reliability of the blast furnace charging equipment, and ensures the stability and high output of the blast furnace. The size of the wear-resistant ceramic lining is mainly related to the size of the ore, impact force, temperature, etc. It is also a specific analysis of the specific situation and is not limited to which one is used.    

Wear-resistant ceramics are mainly used in thermal power, steel, smelting, machinery, coal, mining, chemical industry, port terminals, and other industries with severe wear and tear. Coal conveying, pulverizing, ash discharge, dust removal, and other systems can be installed and used, and techniques such as material conveying, batching, and dust removal in steel plants and sintering plants of smelters can also be installed and used.   Wear-resistant ceramic construction operations are divided into adhesive type, direct-bonded type, impact-resistant type, cemented type, assembly type, wear-resistant ceramic lining board, etc. Wear-resistant ceramics can be used for wear-resistant ceramic pipes such as wear-resistant elbows, wear-resistant straight pipes, wear-resistant tees, and wear-resistant special-shaped pipe fittings.    During the operation of the equipment, due to the constant friction, corrosion, and impact of hard media, the system is prone to leakage. Therefore, all manufacturers pay more attention to the construction of wear-resistant ceramics and have high requirements.   Equipment anti-wear is a systematic project. Different manufacturers take different measures and methods, and the results will vary. At present, the construction steps of our wear-resistant ceramics are generally to repair and polish the equipment first, then glue, apply glue, paste, and cure. Special working conditions also require welding and other work. These seemingly simple tasks are difficult to implement. so easy. It requires careful, experienced staff to complete and is time-consuming.   How to prevent the wear-resistant ceramic sheet from falling off during use? 1. Before the wear-resistant Taozi patch is applied to the surface of the steel part, the rust on the surface of the steel part should be cleaned to make the surface smooth. To obtain a good construction effect, the steel part should be pretreated by sandblasting. The surface of the steel parts needs to be wiped with acetone to achieve a particular effect of degreasing and degumming.   2. The ratio of wear-resistant ceramic glue should be accurate. The ratio of different glues is also different, and it must be strictly controlled. If the ratio is not suitable, the predetermined viscosity cannot be achieved; if the wear-resistant Taozi glue is not spread evenly, it will cause the wear-resistant ceramics to be non-sticky, easy to fall off, and wear-resistant. After the construction of the ceramic sheet is completed, it should be tapped lightly with a rubber hammer, and the construction surface should be flat;   3. Before the construction of the wear-resistant ceramic patch, the working temperature must be clarified. The wear-resistant ceramic piece can withstand a high temperature of 1,000 degrees. Different temperatures should choose glue with different temperature resistance, otherwise, it is easy to cause wear resistance as the temperature rises. The phenomenon of ceramic chips falling off.   http://www.ybnceramic.com/showroom/refractory-silicon-carbide-ceramic-burner-tube-sisic-burner-nozzle.html  

The wear-resistant ceramic composite pipe fully utilizes the weldability of the steel pipe and the high hardness, high wear resistance, corrosion resistance, and high temperature of the corundum ceramics. It is widely used in electric power, metallurgy, mining, coal, chemical, and other industries. It is an ideal wear-resistant and corrosion-resistant pipeline for sand, stone, coal powder, ash, aluminum liquid, and other abrasive granular materials and corrosive media.   Ceramic-composite pipes can be divided into the following types according to different production methods. Direct adhesive wear-resistant ceramic composite pipe: The ceramic patch is lined with the inner wall of the pipe. The manufacturing process is simple, the cost is relatively low, and collision is avoided during ceramic installation and transportation. Ceramic patch pipes are commonly used in an environment where construction is relatively simple and works at normal temperatures (100-150 ℃). Spot-welded card-type wear-resistant ceramic composite pipe: It is suitable for making large-diameter pipes. Paste ceramic orifice plates and weld iron bowls or studs to pipes. This double-layer connection is stronger and the service life of the pipes is longer. But it is more troublesome to make and the cost is higher. Integral ceramic composite pipe: The integral ceramic ring is lined in the pipe, the inner wall is smooth and does not block the material, and has good wear resistance and corrosion resistance. Compared with the patch-type pipe, it is more durable and the cost is slightly higher. According to the comparison of the above wear-resistant ceramic pipes, we choose the appropriate wear-resistant ceramic pipes according to the environment and needs of the pipes.      

Most customers don't know how to use welded wear-resistant ceramic liners for wear protection. We wrote a detailed construction instruction and shared it with you: The construction of welding wear-resistant ceramic lining is generally divided into three parts: 1. Cutting of ceramic sheet; 2. Mixing and smearing of ceramic glue; 3. Welding of ceramic sheets. Cutting of ceramic sheets: Because the hardness of alumina ceramic sheets is very high, it is challenging to process ordinary cutting materials. We generally use diamond blades for cutting. First, set out the construction surface and determine the specific size to be missed. When the blade heats up quickly, it must be cooled with water.    Mixing and smearing of ceramic glue: Ceramic glue is divided into AB glue, which is prepared according to the proportion, and the amount is taken according to the demand. It cannot be prepared too much at one time, and the glue that cannot be used up will become invalid after curing. Apply evenly around the small holes, and be careful not to block the small holes used for welding when applying.   Ceramic sheet welding: After the second step of pasting, the ceramic sheet has been firmly fixed on the working surface, but in order to make the ceramic lining board more impact-resistant, place the small iron cap in the small hole of the ceramic board and use spot welding The process is to weld the iron cap and the steel piece, and after the welding is completed, apply glue to the small porcelain piece and press it into the small hole of the porcelain piece.   The performance characteristics of welded ceramic wear-resistant lining are as follows: The welded ceramic wear-resistant lining has super wear resistance, the wear resistance is 20 times that of ordinary steel, and the Vickers hardness is as high as 1800, which is suitable for most working conditions;   Compared with the paste-type ceramic wear-resistant lining, the welded ceramic wear-resistant lining is more resistant to high temperatures. The corundum ceramic sheet is firmly fixed on the equipment steel plate through wear-resistant ceramic glue and welding nails and can withstand relatively large impact It will not fall off in the environment;   The application of welded ceramic wear-resistant lining is also quite extensive. According to its physical properties, impact resistance, and high-temperature resistance, it is mainly used in equipment with relatively large impact and wear of materials or equipment with relatively high temperature. Welded ceramic wear-resistant lining The plate is the choice of anti-wear material after the paste-type ceramic wear-resistant lining cannot meet the requirements.
