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,
particle xinfengrui, 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-tensil 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.
