Wear-resistant ceramic pipe is a composite pipe that combines ceramic and metal. The wear-resistant ceramic pipe gives full play to the high strength, toughness, impact resistance, good welding performance of steel pipe and high hardness, high wear resistance, corrosion resistance, and heat resistance of corundum ceramics. Good advantages, overcoming the characteristics of low hardness, poor wear resistance and poor ceramic toughness of steel pipes.   The wear-resistant ceramic tube has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical and thermal shock resistance, and good weldability. Therefore, it can be widely used in electric power, metallurgy, mining, coal, chemical industry, and other industries as an ideal wear-resistant pipeline for conveying abrasive granular materials and corrosive media such as sand, stone, coal powder, ash, aluminum liquid, etc.    Wear-resistant ceramic pipes are fundamentally different from traditional steel pipes, wear-resistant alloy cast steel pipes, cast stone pipes, steel plastic and steel rubber pipes. The outer layer of wear-resistant ceramic steel pipe is steel pipe and the inner layer is corundum. The Vickers hardness of the corundum layer is as high as 100-1500 (Rockwell hardness is 90-98), which is equivalent to tungsten-cobalt hard gold. The wear resistance is more than 20 times higher than that of carbon steel pipe, and it is much better than the corundum grinding wheel usually bonded. Ordinary carbon steel substrates are recommended to be used under 380℃; low alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.) are recommended to be used under 540℃; heat-resistant stainless steel substrates are recommended to be used under 800℃.   Because of the various advantages of wear-resistant ceramic pipes, many factories and companies will prefer ceramic wear-resistant pipes, which can also achieve the greatest savings in engineering costs.  

Equipment will be worn during material transportation. For continuous production enterprises, anti-wear is already a critical issue for safe production, especially in iron and steel plants, thermal power plants, cement, ports, and chemicals.   Alumina wear-resistant ceramic sheet is a form of wear-resistant that is economical and has an immediate effect. Its excellent wear-resistant performance is favored by all manufacturers. It is ubiquitous in power production, especially in the pulverizing system. Wear-resistant ceramic sheet model to ensure the service life of the equipment.   Anti-wear of coal mill barrel wall The operating environment of the barrel wall of the coal mill is relatively poor. The temperature in this place is the place where the temperature of the coal mill is relatively high, and it should be around 220°C. Most of them think that the erosion and wear of this part is relatively serious, because the ceramics of the barrel wall of the coal mill are all broken. Starting from this position, it is recommended to use a 10mm thick ceramic sheet in the severely worn area, a 5mm thick ceramic sheet in the non-severely worn area, and a high temperature-resistant adhesive in the high temperature area to ensure that the ceramic does not fall off.    Anti-wear of a static ring of coal mill The temperature of the operating ring of the static ring of the coal mill fluctuates in the range of 200-300 ℃, and the strong erosion aggravates the damage of this part. Because the temperature is too high, it is more important to choose high-temperature glue. In addition, it is not suitable to choose too thick ceramic sheets for this part, which is easy to fall off. In the experiment, we found that 10mm ceramic sheets are more reasonable for static ring anti-wear.   Anti-wear of coal mill separator The separator of the coal mill is very good for anti-wear with ordinary ceramic sheets, and the operating temperature is 70 ℃-90 ℃ mixed air, so the ordinary 5mm alumina ceramic sheet is used for anti-wear in this part, and the service life is 6-8 years.   Anti-wear of the straight pipe section at the outlet of the coal mill separator The operating environment of the straight pipe at the outlet of the separator of the coal mill is relatively bad. The high-speed airflow is mixed with coal particles, which strongly scours the pipe wall and causes this part to be worn out first. The temperature of the mixed air at 70°C-90°C is not very high, so the coal mill The ceramic type used in the straight pipe section of the separator can use a ceramic sheet of about 10-15mm to ensure the anti-wear requirement of the coal mill.

At this time, there is heavy snow with goose feathers floating outside the window. The winter of 2022 feels longer than in previous years, and there is a feeling of biting cold, but my heart is warm at this time. I just signed the first export order after the Spring Festival in 2022,I remember the first cooperation last year, because I don't believe it. It takes more time than domestic orders. From the initial inquiry, signing contracts It took two months for the bank to collect foreign exchange, arrange production, customs and book ships. Although there were some twists and turns in the middle, fortunately, everything was very smooth in the end!    The customer received the goods last year and was very satisfied with the company's products, and also gave a high evaluation. The customer ordered the dovetail wear-resistant ceramic this time. on the device. When using, weld the dovetail guide rail to the parts that need anti-wear, and control the spacing to ensure the gap between the ceramics. Then snap a special ceramic with a dovetail notch to the guide rail, and connect the ceramics in series along the guide rail to complete the installation. The dovetail slotted ceramic liner has the characteristics of high temperature resistance, non-shedding and long service life, and various thicknesses of ceramics can be selected according to the wear conditions, and various special-shaped structure equipment can be customized to form an impact-resistant wear-resistant layer. Widely used in thermal power, mining, cement, smelting and other industries to prevent wear of equipment. We will provide customers with high-quality products and competitive prices and hope that the company will receive more foreign trade orders in 2022.   Because of the repeated global epidemic, the international market has also been affected. China has become a very few countries with economic recovery and growth because of excellent epidemic prevention measures. China will also become a global manufacturing power. I believe the international market will be better and better in the future!  

Wear-resistant ceramics can be used in all kinds of beneficiation equipment with serious wear, including various chutes, pipes, and other equipment. Due to the long-term erosion and wear of the mineral powder, the magnetic separator barrel has a short service life. The use of wear-resistant ceramic sheets is currently the most widely used wear-resistant material, but the ceramic sheets are easy to fall off. To solve this problem, we have the following suggestions : 1. Use high-strength ceramic adhesive: The adhesive strength of our company's ceramic adhesive is more than 2 times that of ordinary ceramic adhesive, which greatly reduces the falling off of ceramic sheets.    2. Select the ceramic sheet with bumps: the surface of the ceramic sheet has bumps, which increases the bonding area and strength of the ceramic sheet, and is less likely to fall off than the flat ceramic sheet.   3. Appropriate construction temperature: When the wear-resistant ceramic sheet is constructed and pasted, the normal construction temperature of the ceramic glue should be guaranteed, especially in winter.   4. It is necessary to continuously sum up experience during construction, and choose careful workers to stick ceramic sheets.   Wear-resistant ceramic sheets are special ceramics fired at high temperatures. Wear-resistant ceramic sheets are widely used in the market and are different from the ceramics used in people's daily lives. In terms of production materials, a large number of industrial materials and metals are used in the production process. It is precisely because of these materials and some special production processes that the ceramic sheet has the characteristics of wear resistance and high hardness.  

Wear-resistant ceramic sheets are also called mosaic alumina ceramics. Depending on the thickness of the ceramic sheets, the working conditions and the frequency of use, the service life of the ceramic sheets will be affected.   The wear-resistant ceramic sheet is a special ceramic with a relatively dense structure and special wear-resistant properties. Its main ingredient is alumina powder. Sintered at high temperature, it has the advantages of high melting point, high hardness and good wear resistance.    The service life of the wear-resistant ceramic sheet is not only related to its quality but also the operating conditions of the equipment, which mainly include the particle size, friction mode, load, material scouring speed, operating temperature, and time.   The wear of wear-resistant ceramic linings is generally divided into cutting wear, fatigue wear, abrasive wear, impact wear, etc. Since the working principle of each wear is different, the wear mechanism is also quite different, but in practical applications, they do not act in isolation, but interconnect and influence each other. Generally speaking, the smaller the particles, the lower the concentration, the lower the flushing speed, and the longer the service life of the wear-resistant ceramic sheet.   Usually, in the network pipe of the slag powder production line, the wear-resistant ceramic lining of 20mm can be used for 8 to 10 years. The materials ground by the raw mill and clinker mill are easier to wear than the slag, and the wear-resistant ceramic lining of the same thickness has a service life of more than 10 years.  

Lithium battery is mainly composed of positive electrode material, negative electrode material, separator and electrolyte, etc. The positive electrode material is an important part of lithium battery, and the cost accounts for about 50% of the whole battery. Lithium battery cathode material production line, from raw material sending, feeding, batching, mixing, and sintering (including secondary or tertiary sintering) to final packaging, each link is connected by pipelines to form a closed conveying system. Pipes are conveying pipes made of PC pipes, glass fiber reinforced plastics and other materials, and the amount of pipes is large.    In the past three years, the rapid development of the domestic new energy vehicle industry has put forward higher requirements for the safety performance and energy density of battery materials, and high nickel ternary has become mainstream. Compared with traditional cathode materials such as lithium iron phosphate, high-nickel ternary materials have higher hardness, higher requirements for wear resistance of pipelines, and stricter demagnetization (no copper, iron, and zinc).   The integral wear-resistant ceramic pipe has smooth inner and outer walls, smooth airflow, extremely low wear, and good pressure resistance, and has the characteristics of super wear resistance, corrosion resistance and high-temperature resistance. The non-metal lining material can effectively block the contact between the powder and harmful substances such as iron, reduce the content of impurities such as iron in the positive electrode material, and improve the safety performance of the battery.    

The ceramic-rubber composite liner adopts an advanced thermal vulcanization process to vulcanize alumina ceramics and rubber together to form a composite wear-resistant ceramic liner of ceramic and rubber. It combines the advantages of high hardness of ceramics and high cushioning and anti-fatigue properties of rubber, and can well solve the problem of equipment wear resistance in the process of conveying bulk materials. The addition of rubber not only makes the lining plate have good anti-wear and anti-corrosion effects but also effectively reduces the environmental noise.    Ceramic rubber composite panels are divided into two-in-one and three-in-one. The two-in-one refers to the ceramic rubber composite board, which is a two-layer structure, mainly used for parts that are easy to install and parts with arc shapes, such as circular cone funnels, belt conveyor redirection driving rollers, etc. The connection method of the two-in-one ceramic rubber composite board adopts a special rubber adhesive, and the composite board is bonded to the steel plate of the equipment with a high-strength adhesive to form a strong and buffering anti-wear layer.   Three-in-one refers to the ceramic, rubber, and steel plate composite board, which is a three-layer structure. The three-in-one composite board comes with bolts, which is convenient for installation. It is mainly used for square chutes, blanking pipes, and blanking point protection of block materials. Terminal conveying equipment, mine transfer equipment, etc.  

Coal preparation is an important process in the comprehensive utilization of coal mine resources. Many metal and non-metal parts in coal preparation equipment will suffer strong wear and quickly fail due to continuous work, resulting in a large amount of human and financial consumption, and at the same time they are unable to Meet the continuous production needs of coal preparation plants. The serious wear and tear of coal preparation equipment and the low service life have become a serious obstacle to the development of coal preparation plants. Therefore, given the unique working conditions of coal preparation equipment, it is of great significance to reasonably research and develop new wear-resistant materials to extend the service life of coal preparation equipment.    Wear-resistant ceramic sheets are an important technical means to improve the reliability of various equipment in coal preparation plants. Among the traditional wear-resistant materials, ceramic materials have become the most common and important type of materials in human life due to their wide sources and superior material properties. They are characterized by high hardness, wear resistance, and corrosion resistance. The wear-resistant ceramic sheet with alumina as the main component has become the most widely used material for its simple process, low processing cost, and good wear resistance. At present, it has been widely used in metallurgy, mining, and chemical industries.   At present, wear-resistant ceramic sheets are widely used in cyclones, chutes, and pipelines in coal preparation plants. The wear resistance of wear-resistant ceramic sheets mainly depends on three aspects, namely, formula, raw material powder and sintering process. From the perspective of the development status of wear-resistant materials and the needs of the coal preparation market, expensive materials such as silicon carbide cannot be used in the coal preparation field on a large scale. Reasonable cost performance of materials, alumina wear-resistant ceramics will be the key research direction of wear-resistant materials.

As the scale of gold mines and beneficiation equipment have begun to become larger, the particle size of the selected raw ore slurry and the inlet pressure and speed of the heavy medium suspension have continued to increase, which has seriously affected the service life of the cyclone. To solve the abrasion resistance problem of the cyclone and increase the service life of the cyclone, the lining of the cyclone was started to improve its wear resistance.   The arc-shaped alumina wear-resistant ceramic liner used in the cyclone has the characteristics of wear resistance, corrosion resistance, high-temperature resistance, impact resistance, and convenient construction. The arc-shaped alumina wear-resistant ceramic liner used for the cyclone has a certain arc, and the arc-shaped liner of various specifications can be customized according to the specific size of the cyclone. It has the characteristics of wear resistance, corrosion resistance, high-temperature resistance, impact resistance, and convenient construction. It is a material for electric power, metallurgy, coal, petroleum, cement, chemical industry, machinery, and other industries (ash slag, coal powder, slag powder, tailings, etc.) Ideal material for wear-resistant surfaces of conveying equipment.   It is very safe and reliable to use arc alumina wear-resistant ceramic liner under high-temperature corrosion, high-temperature wear, or high-temperature corrosion. Under the same industrial and mining conditions, its service life is cast stone, wear-resistant alloy cast steel, steel plastic, and steel rubber Ten times to twenty times as much as the material.   The arc-shaped alumina wear-resistant ceramic liner for the cyclone is fired in a tunnel kiln. The kiln temperature is stable. The fired ceramic liner has a uniform color, a jade texture, and a neat surface without black spots. After years of accumulation, the arc-shaped alumina wear-resistant ceramic liner for cyclones has a certain arc, which is mainly used for cyclones. Various specifications of arc-shaped liners can also be customized according to the specific pipe diameter to make it fit the pipeline perfectly. Inner wall.  

To solve the contradiction between the supply and demand of the sintered ore tank and the problem of the wear and sticky material of the liner, the wear-resistant ceramic liner was selected. The relevant production practice shows that its installation and use are successful. The wear-resistant ceramic liner was installed in the mining tank. After a year and a half of operation, the inspection was carried out, and it was found that the phenomenon of sticky materials that had plagued the production had disappeared. As long as the production is not stopped for maintenance, there is generally no hanging phenomenon. It also reduces the number of cleaning tanks every month, reduces labor intensity, and extends the use time of the wear-resistant ceramic liner. After the equipment is replaced, the liner rarely falls off, and the wear-resistant ceramic is also kept in good condition. Yes, there will be no sticky material, and it is estimated that the use of the equipment can last three to four years.   From the perspective of economic benefits, the use of wear-resistant ceramic liners can greatly reduce the downtime caused by equipment failure or the downtime during material cleaning and can produce a lot of sinter every year. It can reduce the labor intensity of the staff, reduce maintenance work, longer use time, reduce the frequency of component replacement, ensure the continuity of equipment work, and undoubtedly bring high economic benefits.   Through the above practical use, it is proved that the structure of the wear-resistant ceramic liner in the sintered ore tank is relatively simple, and there will be no sticking phenomenon, not to mention the excellent wear resistance, which can allow the equipment to be used for a long time. In addition, the lining board is directly bonded to the mining tank with an organic binder, which can avoid equipment corrosion and extend the use of the mining tank. Compared with the wear-resistant ceramic lining board and the alloy lining board, the cost performance will be higher. It is an enterprise that produces a high-quality choice.
