Sale of high-quality water corundum

Corundum common name, also known as carborundum, is alumina, carbon materials, three materials scrap in an electric furnace to melt reduction obtained through the tan artificial corundum, it is for this name. Corundum main chemical composition is AL2O3, its content 94.5% -97%, and the other containing a small amount of Fe, Si, Ti and the like. Corundum main functions: (1) due to high temperature, corrosion resistance, high strength and other properties, so with pouring steel sliding gate, smelting precious metal, special alloys, ceramics, blast furnace lining (walls and pipes); physicochemical utensils, spark plugs, anti-oxidation resistant coating. (2) Because of high hardness, wear resistance, high strength characteristics, chemical systems, we used a variety of reaction vessels and pipes, chemical pump parts; do mechanical parts, various molds, such as wire drawing dies, Pencil squeeze die nozzle and the like; do tools, dies abrasive, bullet-proof material, human joints, sealing mold ring. (3) corundum insulation materials, such as lightweight corundum brick, corundum hollow sphere and fiber products, widely used in various high-temperature kiln furnace walls and roof, both high temperature and insulation. Corundum size sand by artificial selection corundum block, using processed on the roll, ball, Bamako and other equipment, the particle size by the F8-F325. Mainly used for polishing, grinding, grinding industry, etc., can also according to customer requirements process of working washing, pickling, etc., to meet the different needs of customers. Carbon corundum reprocessed blast furnace and special process, reducing residual carbon content of corundum, the product in use, not powder, not crack, toughness is the preferred raw material abrasives industry, refractory industry. Mainly used in ceramic abrasive, high-grade abrasive, organic abrasive, Belt, coated abrasives, etc., according to the residual carbon content is divided into: calcined corundum C ≤0.05%, a low-carbon corundum C ≤0.10%, ordinary brown corundum C ≤0.15%. Corundum abrasives with high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant characteristics. Dozens of refractory manufacturers have proven that the product has not detonate in the application process, not powder, not crack features. In particular, its cost-effective than traditional corundum, but making the best corundum refractory aggregate and filler. Corundum is high-quality abrasive grade bauxite as raw material, with accessories, by more than 2250 ℃ high temperature in an electric arc furnace refining steel. Its self-sharpening, grinding force. Corundum is mainly used in: 1: Abrasives 2: refractories 3: Blast 4: carborundum wearable Floor 5: precision casting shell mold production corundum parameter index: Purpose Specification Main chemical composition% magnetic material% Al2O3 Fe2O3 SiO2 Ti02 refractories of sand 0-1mm 1-3mm 3-5mm 5-8mm 8-12mm ≥95 ≤0.3 ≤1.5 ≤3.0 - 10mm-0 25mm-0 30mm-0 50mm-0 ≥95 ≤0.3 ≤1.5 ≤3.0 - powder 180 # -0 200 # -0 320 # -0 ≥94.5 ≥93.5 ≤0.5 ≤1.5 ≤3.5 - abrasive mold F 4-80 # ≥95 ≤0.3 ≤1.5 ≤3.0 ≤0.05 90-150 # ≥ 94 ≤0.03 180-240 # ≥93 ≤0.3 ≤1.5 ≤3.5 ≤0.02 P 8-80 # ≥95.0 ≤0.2 ≤1.2 ≤3.0 ≤0.05 100-150 # ≥94.0 ≤0.03 180-220 # ≥93.0 ≤0.3 ≤1.5 ≤3.5 ≤0.02 W 1-63 # ≥92.0 ≤0.5 ≤1.8 ≤4.0 - NOTE: F is abrasive and blasting with the specifications for the coated abrasives P W with specifications for the powder, 320 # namely W40
