ZHENGZHOU HAIXU ABRASIVES CO.,LIMITED

Brown fused alumina Brown fused alumina is made from 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
