Brown Fused Alumina is fused and crystallized under the high temperature of above 2250°C with high quality bauxite, carbon and iron as raw material.
Our product characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion, good corrosion-resistance and so on. Could not burst, no pulverization and crack in using course of refractory.
Brown fused alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2200. A slow solidification process follows the fusion, to yield blocky crystals. The melting help in removing residual carbon , Strict control over Titania levels during the fusion process ensures optimum toughness of the grains. Then The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use.
Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of Grinding wheels and refractory products. This material is also used in other applications like blasting and surface hardening.
