Sichuan quality corundum do precision casting corundum abrasive blasting abrasive corundum

Corundum Introduction: Performance: high hardness, high strength, impact resistance, high temperature, oxidation, corrosion resistance, low creep. Uses: Ceramic resin abrasive blasting, grinding and polishing, and is widely used in advanced refractory runway slip resistant, high temperature matrix coating and metallurgy, chemical and other industrial furnaces, the refractory temperatures up to 1850 ℃, it has a fire-resistant high temperature stable performance characteristics, are widely used in iron and steel, metallurgy, cement and other related fields. Suitable for high abrasion resistance and processing of metals, such as "carbon steel, alloy steel, malleable cast iron, hard bronze and other chemical ingredients:. Al2O3 95% -97.5% SiO2 <1% TiO2 1.5-3.9% Fe2O3 <0.25% CaO <0.25% crystalline:.. α-Al2O3 crystalline constituents including artificial corundum corundum, corundum and special corundum three categories, corundum tan, micro hardness 1800-2200KG / 2200mm2 corundum market corundum blocks, corundum of sand, corundum powder, corundum size sand. corundum common name, also known as carborundum, is alumina, carbon materials, three materials scrap in an electric furnace to melt reduction obtained through brown brown artificial corundum, so as corundum. Corundum main chemical ingredient is AL2O3, its content in a 94.5% to 97%, and the other containing a small amount of Fe, Si, Ti, etc. corundum because of its high hardness, good toughness, multi-purpose the grinding material, is one of the most basic of abrasive. Its main function is as follows (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); physical and chemical containers, spark plugs, anti-oxidation resistant coating (2) due to high hardness, wear resistance, high strength characteristics, in the chemical system used each kind of reaction vessels and pipes, chemical pump parts; do mechanical parts, various molds, such as wire drawing dies, extrusion die nozzle pencil like; do tools, dies abrasive, bullet-proof material, human joints, sealing ring mold (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 heat and keep warm. corundum size sand by artificial selection corundum block, using the processing on the roll, ball, Bamako and other equipment, the particle size by the F8-F325. Mainly used for polishing, grinding, grinding industry, but also according to customer requirements processing methods washing, pickling, etc., can to meet the different needs of customers. carbon corundum reprocessed blast furnace and special process to reduce residual carbon content of corundum, the product in use, not powder, not crack, toughness is the abrasives industry, refractory . The preferred raw material 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 corundum C ≤0.15%.
