Wear resistant alumina ceramic is an alumina ceramic made by AL2O3 as the main raw material, dry-pressed, rare metal oxides (yttrium oxide, rare earth, etc.) as a flux, and baked at a high temperature of 1700 ° C. The Rockwell hardness of the product is HRA80-90, the hardness is second only to that of diamond. The product has the characteristics of good abrasion resistance, high temperature resistance, and convenient construction. The density is only half that of steel, which can greatly reduce the equipment load.
Its theoretical wear resistance is equivalent to 260 times of manganese steel and 170 times of chrome steel. Alumina ceramics are used in chutes, hoppers, pipelines, conveyor belts and other production system equipment. Due to the severe wear of the equipment during the material transfer process, in high-wear environments, high-quality alumina ceramics are often used as abrasion resistance. The lining, the main equipment structure is preserved, and alumina can withstand longer wear and tear before it needs to be replaced. According to different use conditions, it can meet the wear protection requirements of various working conditions.
Products are widely used in steel, electric power, machinery, coal, mining, cement, port and dock industries.
