High wear resistance, corrosion resistance, high-temperature resistance, lightweight, and no metal pollution are all benefits of alumina ceramic pipes. Ceramics made of alumina are fragile and not impact-resistant. Ceramic pipes that are resistant to wear will undoubtedly be jostled or hit while being used. Can ceramic pipes that are resistant to wear be defeated? How exactly do you tap it? The wear-resistant ceramic pipe can be tapped, and to make the ceramic sheet more firmly attached, it must be continuously tapped when the wear-resistant ceramic pipe is being installed. However, there are numerous techniques needed to overcome ceramic-lined pipes.    1. Aluminum oxide ceramics are highly brittle, so try to avoid hitting with hard materials such as metals and stones. It is recommended to use rubber hammers, cork hammers, etc. 2. During the beating process, control the force and beat evenly. It is not advisable to use too much force, otherwise, the ceramics may break. 3. When hitting the wear-resistant ceramic sheet, the position of the hitting point should avoid the edge as much as possible, and hit the center of the ceramic sheet. If the edge needs to be hit, the force should be reduced. 4. In summary, choose the right tools and knocking methods, and try to avoid knocking when wear-resistant ceramics experience harsh environments such as sudden cooling and heat or acid-base corrosion. http://www.ybnceramic.com/concrete-pump-pipeline/concrete-pump-pipe.html

As an important part of the wear-resistant field, wear-resistant ceramics are often used in wear-resistant and impact-resistant industrial environments. It is mainly used in heavy wear industries such as ports, mines, cement, lithium batteries, and steel. Wear-resistant ceramic sheets come in a variety of shapes, including square, triangle, rhombus, hexagon, circle, and special shapes. Differences between these shapes can affect the function and installation of the ceramic sheet. In this article, we walk you through the article to understand the difference between the different shapes and how to choose the right ceramic. The difference between wear-resistant ceramic sheets of different shapes is mainly reflected in four aspects: impact resistance, wear resistance, material viscosity, and installation difficulty.   Impact resistance The impact resistance of alumina ceramics mainly depends on factors such as material properties, thickness, impact angle, etc. In the case of similar factors, the stress and strain distribution during the impact process may vary due to the shape of the ceramic, thus affecting its overall resistance. Fracture performance, resulting in a slightly different performance of the impact resistance of the material. For wear-resistant ceramic sheets of the same material thickness, the circular ceramic sheet bears evenly distributed stress and are not easy to break, while the square and triangular ceramic sheets are easy to be shattered at the corners. In comparison, the impact resistance of circular ceramic sheets is Stronger than square and triangular ones. Taking the ceramic-rubber composite liner as an example, when the triangular, square, and hexagonal ceramics are vulcanized, there are fewer gaps in the middle, less rubber on the surface, and weaker impact resistance. The circular ceramic has large gaps, more rubber on the surface, and strong impact resistance. Under the same conditions, the closer the circle, the stronger the impact resistance of the ceramic sheet, and vice versa.    Wear resistance For ceramic composite liners, the more rubber on the surface, the stronger the impact resistance and the weaker the wear resistance. The surface of the circular ceramic sheet composite liner has more rubber and poor wear resistance, while the triangular and square ceramic sheets have high ceramic coverage and relatively strong wear resistance.   Viscosity to materials The larger the gap between the ceramic sheets, the easier it is for materials to stick together, which may cause material hanging and blocking. Round ceramic sheets are easy to cause material blocking. Triangular and square ceramic sheets have fewer gaps and are not easy to block.   Difficulty of installation The wear of the ceramic sheet mostly starts from the edge of the ceramic sheet, so to prolong the service life of the ceramic sheet and disperse the flow direction of the material, the method of staggered seam paste is usually used when pasting the porcelain. It is relatively easy to install square, triangular, and other regular-shaped ceramic sheets with straight edges, while it is more difficult to install round ceramic sheets, hexagonal ceramic sheets, and special-shaped ceramic sheets.   Choosing the right wear-resistant ceramic sheet depends on several factors. The first consideration is the shape and size of the wear area of the equipment. If the area is square or rectangular, square tiles are the best choice, and if curved or irregular, triangular, diamond, hexagonal, or round tiles may be more suitable. Triangular, square, and diamond-shaped ceramic sheets should be selected as much as possible in working conditions of greater wear and strong viscosity of the material station, and round ceramic sheets can be selected for working conditions of greater impact and less wear.   Our company has rich on-site practical experience and can match the design scheme according to customer needs to help customers achieve better use results.  

In steelmaking, metallurgy, and other industrial production industries, alumina ceramics are mainly used for equipment wear resistance. It is mainly made of alumina as a raw material through a series of processes, such as forming, calcination, and post-processing. The material has high-temperature stability, high wear resistance, and good insulation performance, so it is widely used in machinery, lithium batteries, chemical industries, and other fields. The density of alumina ceramics is an important factor affecting its performance. So, what factors will affect the density of alumina ceramics? Factor One: Alumina Purity Let's talk about the influence of raw materials on alumina ceramics first. The main component of wear-resistant ceramics is alumina, and the purity and particle size of alumina will directly affect the density of alumina ceramics. The greater the purity, the greater the density, and the particle size will affect the accumulation of alumina during the forming process. The lower the particle size, the tighter the accumulation, and the higher the density after calcination. In addition, other materials can be added appropriately during the production process to adjust the density of alumina ceramics to meet different usage needs. Factor 2: Influence of molding method The effect of the forming process on alumina ceramics should be considered. The molding methods of alumina ceramics include dry pressing molding, injection molding process, and extrusion molding. These methods directly affect the density of the finished product. Factor 3: Professionalism of personnel Sintering is one of the main processes in the manufacture of alumina ceramics, which can promote the crystallization of raw materials and form ceramic products. Parameters in the sintering process, such as temperature, time, atmosphere, and cooling rate, affect the density of the finished product. High-temperature sintering can increase the density of the finished product, but excessively high temperatures may cause cracks or deformation of alumina ceramics. Therefore, to achieve the desired density and characteristics, it is very important to choose the appropriate sintering process parameters.   In general, the density of alumina ceramics is affected by various factors, including the purity of alumina, the molding process, and the sintering process. In order to obtain the desired density and characteristics, it is necessary to select the appropriate process indicators during the production process.

Silicon carbide wear-resistant ceramic pipe is a kind of ceramic-lined steel pipe. The lining is made of high-temperature-resistant silicon carbide ceramics with stable organic chemical properties, high heat transfer coefficient, small linear expansion coefficient, good wear resistance, fire resistance, and heat preservation. , high-temperature impact resistance, small size, lightweight, high compressive strength, good environmental protection, and energy-saving effects, etc. Silicon carbide ceramic composite pipe makes full use of the characteristics of seamless steel pipe, such as high hardness, good flexibility, impact resistance, good electric welding performance, high strength of corundum porcelain, wear resistance, corrosion resistance, and good temperature resistance. It gets rid of the seamless steel pipe The characteristics of low strength, poor wear resistance, and poor flexibility of porcelain. Therefore, silicon carbide wear-resistant ceramic pipes have good comprehensive properties such as wear resistance, high-temperature resistance, corrosion resistance, mechanical impact resistance, high-temperature impact resistance, and good welding performance.   Silicon carbide ceramic pipe is a good wear-resistant and corrosion-resistant pipeline, such as transporting particulate raw materials and cutting and eroding substances. The wear-resistant elbow produced by the pipeline is produced by centrifugal separation produced by self-spreading high temperature. The melting point of corundum in ceramic steel pipe is 2045°C. Due to the processing technology, the corundum layer and the steel layer have unique structural characteristics and unique stress fields.   At room temperature, the porcelain layer is subjected to internal stress, and the steel layer is subjected to tensile stress. The two, in turn, become a stable whole. Only when the temperature rises above 400°C, because the expansion coefficients of the two are different, the new stress field caused by thermal deformation and the original stress field in the ceramic steel pipe offset each other, so that the two are in balance. When the temperature rises to 900°C, the silicon carbide wear-resistant elbow is put into cold water and soaked repeatedly, and the composite layer has no gaps or collapses, which mainly shows the high-temperature impact resistance that ordinary ceramics do not have.   Silicon carbide wear-resistant ceramic pipes are mainly used in logistics transportation systems in high-temperature environments. They have strong wear resistance and corrosion resistance. They are cost-effective pipes in high-temperature transportation systems.  

Metal pipes and ceramic pipes are two kinds of pipes that are more common in industrial production today. In addition to bearing the burden of material transportation, they also shoulder many responsibilities such as wear resistance, corrosion resistance, and safety protection. Then when ceramic pipes meet metal which one would you choose? Anti-wear: From the perspective of anti-wear, the most critical factor affecting wear resistance is the hardness of the material. Both metal and wear-resistant ceramics can increase the hardness by changing the formula and improving the process. However, the hardness and weldability of metal pipes conflict and restrict each other. When the hardness increases, the weldability will decrease significantly. If both are to be considered, the cost will rise linearly. In comparison, the hardness of ceramic pipes can reach HRA90 within the ordinary price range, the anti-wear ability is very strong, and the price-performance ratio is very high. Anti-corrosion: Anti-corrosion mainly refers to acid-base corrosion. Metal materials have active chemical properties and are easily corroded by acid-base reactions. Wear-resistant ceramics are calcined at a high temperature of 1700°C to convert alumina into α-alumina with very stable performance, which has excellent resistance to acid and alkali corrosion.   Safety performance: The so-called safety performance refers to the stability of the pipeline during use, that is, whether there will be problems such as material hanging or material leakage during material transportation, which mainly depends on the smoothness and connection of the pipeline. Firmness. The initial smoothness of metal pipes and ceramic pipes is relatively high, but the smoothness of metal pipes will decrease after wear, and wear-resistant ceramic pipes will become smoother as they are worn because of the addition of self-lubricating components. From the above three points, in general, in industrial applications, the performance of wear-resistant ceramic pipes with the same cost performance has obvious advantages, and in the emerging industry of lithium batteries, ceramic pipes can also isolate metal pollution, which the market has recognized—highly recognized.

Alumina wear-resistant ceramic linings include direct bonded flat plates, welded orifice plates, trapezoidal liners, special-shaped liners, curved liners, grooved liners, etc., widely used in mines, steel, thermal power, power generation, cement, ports Wear protection of other equipment.   The shape of the wear-resistant ceramic lining is different, and the construction plan is also different.   Direct-adhesive ceramic plate: In the early stage, the surface of the equipment needs to be polished and dusted. Apply the prepared ceramic glue on the liner, and then fix the wear-resistant ceramic liner on the steel part's surface as the equipment's wear-resistant layer. Welding orifice plate with iron wrist: first fix the iron wrist in the orifice plate, then select the ceramic lining plate on the surface of the steel part with ceramic glue, and then weld the iron wrist on the equipment surface by spot welding, which plays a double fixing role. It can work at a higher temperature for a long time. The direct-adhesive plate can work in an environment below 300 degrees for a long time, and the welded orifice plate is double fixed by the iron wrist and ceramic glue. It can work in an environment below 700 degrees for a long time.

What is a cermet-lined composite pipe?"Metal-ceramic-lined composite pipe" Many buyers feel a little strange when they see the name of this product. Why are there metal and ceramic? What exactly is a cermet-lined composite pipe?   The metal-ceramic-lined composite pipe is the ceramic pipe we are familiar with, because the outer steel pipe is made of metal (ordinary steel pipe or stainless steel pipe), and then lined with ceramics, so sometimes it is called a metal-ceramic-lined composite pipe. That is, take the material directly in the title name. Among them, there are also two types of lining ceramics. Although they are all alumina ceramics, the production process is different. One is a ceramic patch, and the other is self-propagating ceramics. The choice of lining ceramics is determined according to working conditions, conveying medium, expected service life, etc. Simply put, ceramic patches are more wear-resistant and have a longer service life, but are not resistant to corrosion and high temperature (due to glue), Self-propagating ceramics are not as wear-resistant as ceramic patches, but they are resistant to corrosion and high temperature.

According to different processes, ceramic lining plates can be divided into three types: adhesive ceramic lining plates, welded ceramic lining plates, and dovetail ceramic slot-type lining plates. Today, let's find out what kinds of wear-resistant ceramic lining plates can be classified according to different ceramic materials.   1. Ceramic rubber two in one composite lining plate, ceramic-rubber two-in-one composite lining plate adopts a cold vulcanization process, vulcanizing high-purity alumina wear-resistant ceramics on top of high-grade rubber with better material, forming impact resistance and wear resistance. The ceramic-rubber composite liner can be used in equipment with relatively high impact force, but because the rubber is not strong in high-temperature resistance, even if high-grade rubber with better material is used, try to ensure that the operating temperature is within 200 ℃.    2. Ceramic steel two-in-one composite lining plate, ceramic steel two-in-one composite lining plate is to install wear-resistant ceramics on various metal materials by sticking or welding + sticking, and then welding or bolting the ceramic steel two-in-one composite lining board. The one-in-one composite liner is installed in the equipment that needs anti-wear. Compared with installing the wear-resistant ceramic sheet directly in the equipment, the ceramic-steel two-in-one composite liner is more convenient to install and disassemble, and it is more convenient to replace. Serious parts can use ceramic steel two-in-one composite lining, which can be removed and replaced regularly. The construction is simple and fast, saving a lot of time and cost.   3. Steel-based cast ceramic liner, steel-based cast ceramic liner, also known as a fused ceramic liner, is different from the ceramic steel two-in-one composite liner in that the steel-based cast ceramic liner is an arrangement of wear-resistant ceramics in a certain way. Melted into steel, it not only retains the high wear resistance of ceramics but also retains the toughness of steel. Therefore, the wear resistance of steel-based cast ceramic linings is usually stronger than that of metal wear-resistant plates, and slightly lower than that of ceramic-steel two-in-one composites. Liner. However, because the toughness of steel is retained, the impact resistance and fracture resistance of steel-based cast ceramic linings are stronger than those of steel two-in-one composite linings, and the temperature resistance is higher than that of ceramic-rubber two-in-one composite linings. It is used in equipment with high impact in a high-temperature environment. http://www.ybnceramic.com/alumina-ceramic-liner/impact-resistant-linings.html  

Most ash conveying pipelines use pneumatic conveying, which has the characteristics of high airflow pressure, fast flow rate, and long conveying time. There are often hard particles in the conveyed materials, which seriously wear the ash conveying pipeline. Abrasion of the ash conveying pipeline will cause serious pulverized coal leakage, pollute the environment, and cause potential safety hazards and waste materials.    There are three common solutions: 1. Reducing the air pressure during ash conveying can reduce the material flow rate while saving energy, thereby reducing pipe wear. This method reduces the efficiency of ash conveying in the pipeline, and the effect is not ideal. 2. Make a backpack patch structure in the parts where the ash conveying pipeline has been worn or may be worn, and pour cement or wear-resistant materials into the backpack. The operation is simple and the cost is low, but it can only partially solve the problem and cannot fundamentally solve the problem. 3. Improve and optimize the wear resistance of the pipeline itself. The lining of the pneumatic conveying pipeline with alumina ceramics is an effective method to solve the wear of the ash conveying pipeline. Corundum is the main component of wear-resistant ceramics. Its hardness can reach above HRA88, and the wear resistance is far super metal. The service life is 7-10 times that of metal pipes.
