Wear-resistant ceramic liner, also known as alumina liner, alumina wear-resistant liner, or alumina ceramic liner, the main component is aluminum oxide, namely aluminum oxide (Al2O3), which is a kind of corrosion-resistant surface of industrial equipment, Excellent non-metallic material with wear resistance, high-temperature resistance and impact resistance.
The wear-resistant ceramic liner is a white rectangular parallelepiped. According to different shapes, it is divided into the adhesive liner, welded liner, trapezoidal pipe liner, and arc-shaped cyclone liner.
1. The bonding liner is a solid white cuboid, and the common specifications are 150*100, 150*50, 120*80, and other models. Fix the ceramics on the steel plate with glue during construction.
2. There is a round hole in the middle of the welding lining plate, which is fixed by sticking and welding. The iron cap is welded through the middle round hole and the steel plate, and then a porcelain cap is used to protect the welding point. Compared with the adhesive liner, the welded liner has stronger impact resistance and can withstand higher temperatures, which solves the limitation of the temperature influence of the glue.
3. The vertical section of the trapezoidal pipe liner is a trapezoid, and it is a ceramic liner used for small pipe diameter (diameter less than 600mm) pipes. Common specifications are 150*45/40*25, 150*50/47*20, 150*40/37*20 and other models. The trapezoidal liner is self-arching in the pipe into a circle. In addition to the adhesive force of the ceramic glue, there is also pressure between each other, so it is stronger.
4. The arc-shaped cyclone liner is a kind of arc-shaped liner customized according to different cyclone sizes. Each circle requires a set of molds, which is relatively expensive. The arc-shaped plate can completely fit the inner wall of the cyclone vertebral body and can play a very good abrasion resistance on the inner wall of the cyclone with considerable impact force and serious wear. Its thickness is generally 20mm or 25mm. The wear-resistant ceramic liner has the characteristics of wear resistance, corrosion resistance, high-temperature resistance, impact resistance, and convenient construction. It is used as materials for electric power, metallurgy, coal, petroleum, cement, chemical, machinery, and other industries (ash slag, coal powder, mineral concentrate) , Tailings, etc.) ideal material for the wear-resistant surface of conveying equipment.
