Corundum is a high-grade abrasive grade bauxite as raw material, together with the auxiliary materials, in the electric arc furnace by 2250 â?? above the high temperature refining, on the basis of the second refining through the high-strength magnetic separator, refractoriness above 1850 Our production of rs corundum with high purity, good crystallization, strong mobility, low linear expansion coefficient, corrosion-resistant features. The product in the application process with no detonation, no powder, no cracking characteristics, commonly used in abrasive abrasive, refractory raw materials industry. Corundum in the smelting method can be divided into: pouring furnace and fixed furnace. The main products are: corundum bama sand, the roller sand, ball mill sand, paragraph sand, p sand, fine powder, powder. Special treatment products are: high temperature calcined corundum, the temperature calcined corundum, washed, pickling, dry cleaning (wind washing). Application scope Abrasive abrasive categories: grinding wheel, belt, sandpaper, emery cloth, cutting film, sandblasting process, grinding, wear-resistant floor, water knife cutting, coated abrasive, consolidation abrasive. Refractory materials: castables, refractory bricks, ramming material, skateboard, outlet, ladle, furnace lining, precision casting, and so on.
