Alumina Ceramic Tiles
Introduction
The alumina ceramic tile is a special corundum ceramic made of AL2O3 as the main raw material and rare metal oxide as the flux, which is calcined at a high temperature of 1700 Baidu. Its Rockwell hardness is HRA80-90, and its hardness is second only to diamond. The performance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron, so it can greatly extend the service life of pulverized coal pipe elbows.
Advantages
Alumina ceramic tile has the characteristics of wear-resisting, corrosion resistance, high temperature resistance, impact resistance and convenient construction. It is an ideal wear resistant material for conveying equipment in electric power, metallurgy, coal, petroleum, cement, chemical industry, machinery and other industries. Arc alumina wear resisting ceramic is used, which is very safe and reliable under high temperature corrosion, high temperature wear or high temperature melting, and has long service life. Under the same industrial and mining conditions, its service life is 10 to 20 times of casting stone, wear resistant alloy cast steel, steel rubber and other materials.
