Ceramic composite liner

short description:

Industrial wear has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials have also been innovated. Cast stone, cast steel, bimetallic wear-resistant plate, wear-resistant steel, alloy steel, polyurethane, tortoiseshell mesh wear-resistant coating, wear-resistant ceramics, centrifugal casting composite ceramics and other materials have emerged. Among them, alumina lined wear-resistant ceramic has become the most widely used wear-resistant material due to its high wear resistance, high hardness, oxidation resistance, corrosion resistance and high and low temperature resistance. However, the toughness of its alumina wear-resistant ceramics is not as good as zirconia. After years of research, ZTA ceramic particles of zirconia toughened alumina have been developed.

Application

Zirconia toughened alumina (ZTA ceramics) is defined as an "ultra wear-resistant and impact resistant" ceramic with the model of NMC-ZTA. This multiphase ceramic material not only shows the characteristics of high toughness and strength of zirconia ceramics, but also retains the advantages of high hardness of alumina. It is the combination of strength and strength of materials. Its wear resistance has also been greatly improved, especially in the transportation of large bulk materials. For example, under the special working conditions of large bulk materials, high drop, large impact force and hard materials, ZTA ceramic lining plate has a particularly prominent advantage.

ZTA ceramic lining plates are used in places with large impact force and high drop, and aluminum oxide wear-resistant ceramic lining plates are used in places with relatively small erosion and easy wear. This is the secret of why Jingcheng wear-resistant ceramic lining plates are both wear-resistant and impact resistant. Through optimization design, the overall service life of the chute is increased as much as possible.

Use of wear-resistant ceramic lining plate: it is a wear-resistant material for material conveying equipment or liquid flowing through the pipe surface in petroleum, mining, steel plant, power plant and other industries. Its main function is to effectively resist the impact of materials on the pipe wall, the corrosion of chemical substances and the thermal impact of materials, reduce the wear of equipment components, thus greatly reducing the cost of frequent maintenance, and extending the service life of equipment, It is a good choice for industrial wear-resistant, impact resistant and corrosion resistant materials. Features of wear-resistant ceramic lining plate: It has the characteristics of wear resistance, impact resistance, corrosion resistance, high temperature resistance, convenient construction, etc. It is an ideal wear-resistant material for the surface of conveying equipment of materials (such as ash, pulverized coal, mineral powder, tailings, cement, etc.) in the power, metallurgy, coal, petroleum, cement, chemical industry, machinery and other industries. It is very safe and reliable to use in the occasions of high temperature corrosion, high temperature wear or high temperature melting corrosion, and its service life is longer than that of cast stone, wear-resistant alloy cast steel, steel plastic The installation of wear-resistant ceramic lining plates made of steel rubber and other materials is ten to twenty times higher: there are two types, welding and adhesive, depending on the specific construction environment. Welding is generally used under the working condition with large impact force, and the adhesive can affect the adhesion. The temperature cannot exceed 300 degrees.

We only choose good raw materials. Our wear-resistant ceramic lining plates are fired in tunnel kilns. The kiln temperature is stable. The fired ceramic lining plates are uniform in color and have the texture of jade. From the outside, the surface is neat without adhesion, and there is no black spot (the content of impurities in high-quality raw materials is small). They have passed the ASTM65 test. B. There are many wear-resistant ceramic liner molds. After years of accumulation, the company has hundreds of sets of molds for customers to choose from. The product selection is strict. We do what we say and do not make false promises With many years of experience in the construction of wear-resistant ceramic lining plates and professional technicians, they can provide technical guidance and identify methods for installing wear-resistant ceramic lining plates A The good wear-resistant ceramic lining plate has a flat surface, no black spots, smooth without roughness, and uniform color. The shape of the iron distribution bowl of the welded wear-resistant ceramic lining plate is consistent with the inner hole of the lining plate, and the minimum weight is not less than 5 grams B The density and alumina content can be calculated by measuring the density. C is used for wear resistance test. The sandblasting machine is used to measure the aluminum oxide content within 60 minutes at a pressure of 40 kg/cm3, a distance of 50 mm, a spraying angle of 45 degrees

Application of wear-resistant ceramic lining plate Material conveying system in iron and steel industry: bucket wheel, hopper, silo, belt conveyor apron, trolley three-way bucket, receiving hopper batching system: mixing silo, primary mixing cylinder, secondary mixing cylinder, mixing disc, mixing cylinder scraper, pelletizing disk sintering system: Beneficiation hopper under vibrating screen, raw material transport chute, cyclone dust collector and pipeline, fan impeller Limestone crushing system in cement industry and raw fuel pre homogenization system: chute, hopper, Belt pulley raw material mill system: deflector vane of powder concentrator, cone of powder concentrator, pipe from vertical mill to cyclone, cyclone, fuel mill (steel ball mill), shell of powder concentrator, inner cone, coal powder pipe fuel mill (steel ball mill): shell of powder concentrator, inner cone, coal powder pipe, coal powder return pipe, port industry berth fixed hopper, bucket wheel fixed hopper, belt conveyor transfer station fixed hopper, ship unloader hopper
