Brown Fused Alumina (BFA) is a kind of refractory, hard and chemically resistant material. It is produced by smelting Calcined Bauxite in an electric arc furnace at temperatures higher than 2000°C.Corundum is bauxite, coke (anthracite), scrap iron as main raw materials, in electric arc furnace high temperature melting nei crystals into, it has high hardness and great toughness, grinding force is powerful, high temperature resistant, the efficiency high characteristic, is the quality of abrasive abrasive materials and advanced refractory materials. Makes with it, apply to the abrasive high strength high metal, can cut, grinding various general steel, carbon steel, alloy steel, general malleable green steel,also can green steel as senior refractory materials, widely used in steel, chemical and other industries.
Mainly used for abrasion and high temperature resistant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc..
Sandblasting abrasive
Mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin etc..
Abrasion resistance ground
Mainly used for non-slip of airport and road, chemical factory board paving.
Precision casting
Investment casting technics of stainless steel and aluminium casting in coating.
