Brown corundum is made of high-quality abrasive grade bauxite as raw material, with auxiliary materials, and is refined in an electric arc furnace at a high temperature above 2250 °C. The RS brown corundum produced by our company has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. The product has the characteristics of no explosion, no pulverization and no cracking during the application process, and is often used in the abrasives and refractory raw material industries. The smelting method of brown corundum can be divided into: dumping furnace and fixed furnace. The main products are: brown corundum Barmac sand, roller sand, ball grinding sand, segment sand, P sand, fine powder, micro powder. Special treatment products are: high temperature calcined brown corundum, medium temperature calcined brown corundum, water washing, pickling, dry cleaning (air washing). Scope of application Abrasives: grinding wheel, abrasive belt, sandpaper, abrasive cloth, cutting disc, sandblasting process, grinding, wear-resistant floor, water jet cutting, coated abrasive, bonded abrasive, etc. Refractory materials: castable, refractory brick, ramming material, sliding plate, nozzle, ladle, furnace lining, precision casting, etc.
