Artifical abrasives/ brown fused alumina/BFA

Artifical abrasives/ brown fused alumina /BFA 1. Introduction Brown fused alumina is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200°c, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc. 2.Application: (1) as there is high temperature, corrosion resistance, high strength properties, it poured with steel sliding gate, smelting rare metals, special alloys, ceramics, iron-smelting furnace of the lining (walls and tubes); physical and chemical containers , spark plugs, heat-resistant anti-oxidation coating.  (2) due to high hardness, wear resistance, high strength characteristics, in the chemical system, used for a variety of reaction vessels and pipelines, chemical pump parts; to do mechanical parts, various molds, such as the Roberts mold, extrusion die nozzle pencil lead, etc.; do tool, die grinding, bullet-proof material, the human body joints, sealing ring mold.                (3) corundum insulating materials, such as lightweight corundum brick, corundum hollow ball and fiber products, widely used in a variety of high-temperature kiln furnace walls and roof, both high-temperature insulation again. 3.The physical and chemical analysis:
