Brown fused alumina corundum
Brown fused alumina is bauxite, coke (anthracite) in raw materials, melting in electric arc furnace at high temperature. The main chemical compositions are Al2O3, TiO2 and a little SiO2, Fe2O3 and so on. Its hardness is HV1800-2200 and it’s tougher than Sic. The abrasive made from it is suitable for high tensile strength metal, such as a variety of common steel, malleable iron and hard bronze. It also can be used as advanced refractory.
Application
1) Abrasive: Produce ceramic grinding wheel, resinoid gringding wheel, Grinding stone, Grinding block, sand paper, sand cloth, sand belt, polish wax, abrasive paste, coating etc..
2) Refractory material: 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..
3) Sandblasting abrasive: Mainly used for various material work pieces to decontaminate, derusting, prevent corrosion, remove oxide skin etc..
4) Abrasion resistance ground: Mainly used for non-slip of airport and road, chemical factory
board paving.
5) Precision casting: Investment casting technics of stainless steel and aluminium casting in coating
