The impact of materials falling from high altitudes on the chute is large, which causes serious chute wear. In the past, manganese steel lining plates were generally used for wear prevention, which did not play a significant role. The wear is still very serious, and it will need to be replaced soon, leading to increased costs and affecting the efficiency of the factory. It is necessary to replace it with a more wear-resistant material, which requires a higher wear resistance.   Alumina ceramic is a kind of wear-resistant material, which is mainly made of aluminum oxide and fired for more than 1000 degrees. It has the characteristics of high-temperature resistance, high hardness, impact resistance, corrosion resistance, etc. Its wear resistance is 266 times that of manganese steel. It can well resist the impact of materials. Using wear-resistant ceramics to replace manganese steel lining plates can prolong the service life of equipment by more than 10 times.   The aluminum oxide ceramic lining plate is welded inside the chute to form a solid anti-wear layer. The welding can prevent the ceramics from falling off easily and can better resist the impact of materials. The welded orifice plate is double fixed by an iron bowl and ceramic glue, which can work in an environment below 700 ℃ for a long time. It is suitable for anti-abrasion protection of steel plant hoppers, silos, chutes, coking plant chutes, cement plants, thermal power plant coal chutes, and other equipment.  

The ash conveying system of the cement plant mainly adopts pneumatic conveying, because the ash conveying volume is large and the flow velocity is fast, the wear and tear of the pipeline are very serious. Once the pipeline wears out, it will easily lead to the deterioration of the airtightness of the pipeline, affect the transmission efficiency, and even stop the maintenance of the pipeline, so that the work will be at a standstill. Therefore, we need frequent repairs and maintenance. After understanding the principle of wear, we can optimize the pipeline structure in advance.   The reasons for the wear and tear of pneumatic conveying pipelines are summarized as follows: 1. In the process of pneumatic conveying, friction occurs between the material and the inner wall of the equipment pipeline. The greater the particle hardness of the material, the more serious the wear on the pipeline; the smaller the radius of the pipeline, the more serious the wear.   2. The ash and slag themselves have abrasions such as scour, impact, and scratches on the pipeline. As the material penetrates the surface, the tissue on the surface of the pipeline is partially damaged and detached.   3. The physical properties of the material also affect the wear of the pipeline. The main manifestations are: the larger the material particles, the greater the hardness, the sharp edges and corners on the surface of the material particles, the increased wear, the increased material concentration, and the increased wear.   4. Due to the contraction and diffusion effect of the elbow itself of the pneumatic ash conveying pipeline and the formation of the eddy current area, the degree of erosion and wear of the ash on the inner side of the elbow is much greater than that on the outer side of the ash. Although the concentration of ash and slag on the outside of the elbow increases due to the action of inertia, the contraction effect of the elbow and the formation of eddy currents greatly accelerate the flow velocity inside the elbow and cause multiple flushes, which cause serious wear on the inside of the elbow the main reason.   5. With the increase of ash concentration, pipeline flow velocity, and ash particle size during operation, the wear speed of the pipeline is correspondingly accelerated.   Therefore, when designing and installing the pneumatic ash transportation pipeline, the pipeline should be arranged reasonably. At the same time, to improve the service life of the elbow of the ash removal pipeline, it is first suggested that the elbow part be lined or filled with wear-resistant materials, or all the ash transportation Pipes are replaced with wear-resistant ceramic pipes. Attach an easily replaceable wear-resistant ceramic backpack to the outside of the very worn elbow, or thicken the easily worn part of the elbow and weld flanges at both ends of the elbow for easy replacement. Secondly, when designing and installing, try to match the ash discharge volume, water pump, motor, and pipeline reasonably, to ensure a reasonable gray-water ratio and pipeline flow rate, and to reduce pipeline wear.  

Alumina ceramics have been widely used in many industries of the national economy because of their excellent performance. Do you know the maintenance methods of alumina ceramics? 1. Pay attention to effective storage Because alumina ceramic is a pure ceramic material, it is necessary to pay attention to the effective use of packaging during storage to avoid moisture or the influence of various pollution sources in the air. Alumina ceramics need a relatively dry and well-ventilated environment Store in the middle and do a good job of moisture-proof work.    2. Pay attention not to be hot and cold during processing Because alumina ceramic materials have good hardness and strength, but their performance will be affected by hot and cold processing, alumina ceramic manufacturers suggest that users should pay attention to maintaining a constant temperature during operation, and not cause product quality to be caused by hot and cold Problems are prone to cracks. 3. Choose an effective processing method Although alumina has many advantages in use, it is also difficult to process. Therefore, it is necessary to choose the corresponding effective processing method to improve the processing efficiency and quality of the product. Alumina ceramics are characterized by high brittleness during processing, so grinding or cutting and laser heating should be selected for processing operations.

Wear-resistant ceramics, also known as modern ceramics, mainly comprise high-purity alumina. Because their toughness and hardness are much higher than ordinary daily-use ceramics, they can be used as wear-resistant materials in industrial equipment.   As an industrial wear-resistant material, wear-resistant ceramics have good wear and corrosion resistance. Still, because of their relatively high hardness, which is close to the hardness of diamonds, it isn't easy to reprocess wear-resistant ceramics. Let's get to know the processing technology of wear-resistant ceramics.    The processing technology of wear-resistant ceramics has the following three categories according to the processing method: 1. Surface treatment: Use diamond grinding discs to grind wear-resistant ceramics or use sandpaper to polish the surface of wear-resistant ceramics; 2. Cutting treatment: Because the hardness of wear-resistant ceramics is relatively high, ordinary cutting machines cannot cut ceramics, and special equipment such as diamond cutting discs or ultrasonic waves, lasers, and water jets are required for cutting treatment; 3. Surface marking: using photolithography technology or etching technology through chemical or physical means to make wear-resistant ceramics form concave-convex or hollow-out molding effects; 4. Wear-resistant ceramics are difficult-to-process materials, which cannot be processed in general machining workshops. The processing of wear-resistant ceramics generally requires special processing tools and processing techniques, so it is a better choice for professionals to operate and process.    

The scientific name of zirconia is zirconia, and its molecular formula is ZrO2. It is the main oxide of zirconium. The minerals containing zirconium in nature mainly include baddeleyite and zircon. Zirconia is usually a white odorless and tasteless crystal, insoluble in water, hydrochloric acid, and dilute sulfuric acid, chemically stable, and has the characteristics of high hardness, high melting point, high resistivity, high refractive index, and low thermal expansion coefficient. Wear-resistant ceramics, refractory materials, machinery, electronics, optics, aerospace, biology, chemistry, etc. have been widely used in various fields. Our common artificial drills and dental implants also use zirconia as the main material.    Properties of Zirconia 1. High hardness: The hardness of zirconia products can usually reach more than 7.5 on the Mohs scale, and the hardness of some products such as zirconia ceramics can exceed 9, second only to diamond. High hardness means that it has strong wear resistance, so zirconia ceramics are good wear-resistant materials. 2. High melting point: The melting point of zirconia is as high as 2715°C, and its chemical properties are stable. It is an excellent refractory material. 3. Low thermal conductivity and low expansion coefficient: The thermal conductivity of zirconia is relatively low among common materials (1.6-2.03W/(m.k)), and the thermal expansion coefficient is close to that of metal. Therefore, zirconia ceramics are suitable for official ceramic materials, such as zirconia ceramic mobile phone exterior structural parts. 4. Special conductivity: Zirconia does not conduct electricity at room temperature, and its resistivity is extremely high. However, in a high-temperature environment, zirconia has a certain conductivity. Using this principle, zirconia is also used in many electronic devices.  

Construction process 1. Grind and dust and degrease the metal surface where ceramics need to be pasted (if there is an oil stain, it should be cleaned with 99% acetone; if the bonding surface is non-metallic, the surface should be polished and roughened). 2. Stir the glue evenly, mix, and mix thoroughly according to A: B=2:1 (weight ratio), apply it on the metal surface, then paste the wear-resistant sheet, hit it with a rubber hammer, and cure it at room temperature for 2 hours. 3. After curing at room temperature for 8 hours, use a small hammer to gently tap to check, and listen to the sound to judge whether there is any phenomenon that the adhesive is not fully coated. If so, it needs to be partially re-pasted.    Precautions 1. When the humidity is high in the rainy season, in order to prevent rust, glue should be applied immediately after grinding to prevent rust. 2. The proportion of glue should be accurate to avoid construction quality problems caused by inaccurate glue mix. 3. When the temperature is lower than 10°C, heating and curing should be adopted, and an iodine-tungsten lamp can heat the surface to be bonded to about 30°C, apply glue and glue bond, and heat until cured. If heating measures are not taken, especially when the temperature is lower than 0°C, the adhesive will freeze and the surface looks cured, but there is no bonding strength. The user will experience ceramic peeling off during use. The heating temperature should not exceed 50°C, otherwise, it will cause the glue to react violently and cause foaming, affecting the bonding strength.

Today we will talk about the application of abrasion-resistant ceramic lining in the wear-resistant feeding chute of the powder concentrator. First of all, what is the powder concentrator? The powder concentrator is an important component of the closed-circuit circulating grinding system. It is widely used in the production systems of cement plants and other powder concentrators and plays the role of regulating the size of finished products. Its reliability affects the normal operation of the entire production line. Due to the high abrasiveness and humidity of slag, the cleaning and replacement of worn parts of the powder concentrator have seriously affected the normal production of the powder concentrator.    Abrasion-resistant ceramic lining can solve this problem well as a solution for wear-resisting and anti-blocking of the feeding chute of the powder concentrator. The alumina ceramic lining is made of microcrystalline wear-resistant aluminum oxide, sintered at 1700 ° C and high temperature. It has high hardness and wear-resistant properties and can be widely used in powder concentrators of grinding systems in thermal power, cement, chemical industry, metallurgy, port, mining, and other industries.   The ceramic lining brick is fixed by pasting, which facilitates installation and replacement, reduces the specification and quantity of spare parts, and saves user costs. Secondly, the alumina lining has wear resistance, a smooth surface, no scraping, and no material, which can effectively prevent material blocking and is convenient for cleaning.   High alumina ceramic lining bricks have been applied in many industries because their characteristics can be targeted at different types of materials. Its wear-resistant and anti-clogging effect is noticeable, which greatly reduces the probability of material clogging, prolongs the equipment cleaning cycle, reduces the user's downtime and maintenance time, and creates additional economic benefits for the user, and the response is quite good.  

Alumina precision ceramics is a high-tech ceramic product made of alumina materials. Different from ordinary alumina ceramics, alumina precision ceramics are mainly reflected in "precision", which is specifically reflected in the more complex structure of the finished product after production. In terms of relatively small size and less secondary processing, the performance characteristics of alumina precision ceramics are similar to those of alumina ceramics, such as high-temperature resistance, wear resistance, corrosion resistance, and high hardness. Therefore, alumina precision ceramics are widely used in electronics, information, and communications. , aerospace, military, and other fields have also been widely used.   Due to its good physical and chemical properties, alumina fine ceramics occupy a significant position in many fields. First of all, in the electronic field, alumina precision ceramics are mainly used in the production of capacitors, electronic potentiometers, voltage regulators, and other electrical components. Because of its high-temperature resistance, vibration resistance, corrosion resistance, and mechanical strength, it can ensure the efficient and stable operation of electrical components.   In the industrial sector, fine alumina ceramics also occupy an important position. It has very high hardness and wear resistance. It can be made into wear-resistant parts such as wear-resistant pipes, used in industrial machinery, and used in the production of mechanical precision parts. In medical equipment and other fields, alumina precision ceramics can be used to make human body substitutes such as artificial arms and artificial knees and they have good biocompatibility and mechanical properties.   To sum up, alumina precision ceramics have good performance and wide application, and its manufacturing process is relatively strict, but it has high added value and economic benefits. Therefore, the future market prospect of alumina fine ceramics is very broad and has great development potential. http://www.ybnceramic.com/wear-resistant-ceramic-pipe/alumina-toughened-zirconia.html
