Abrasive Black Sic Black Silicon Carbide for Grinding Wheels

Product Description

Abrasive Black Sic Black Silicon Carbide for Grinding Wheels
Black Silicon Carbide is brittle and sharp.It is produced at high temperature in electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between Aluminum Oxide and Synthetic Diamond. Mechanical intensity of it is higher than Aluminum Oxide. It is brittle and sharp and has electrical and heat conductivity in some degree.
Silicon carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, ceramic, etc. It is also broadly used as high-grade refractory material and metallurgical additive.

Usage of the silicon carbide:
Firstly: Silicon carbide is mainly used as abrasive in manufacturing grinding wheel, abrasive paper, abrasive belt, abrasive, grinding, grinding head, grinding paste, etc.
Sic grinding tool can be used in the manufacture of consolidation, coated abrasive grinding and freedom, to the processing of glass, ceramic, stone, jade, cast iron, stainless steel, floor tile and some non-ferrous metals, hard alloy, titanium alloy, high speed steel props and grinding wheel etc.
The second: refractory materials (silicon carbide powder, silicon carbide particles)
Silicon carbide as inorganic nonmetallic materials with high temperature resistant, wear resistant characteristics of silicon nitride combined with silicon carbide products can be used in the blast furnace ceramic cup, etc.In air brick as ladle with magnesia carbon brick, aluminum silicon carbide can also act as antioxidants added.
Made of silicon carbide refractory plate high crushing strength, long service life, low thermal capacity, low thermal conductivity.The brittle material, good toughness;Good flatness, size accurate,Easily cut installation, construction is convenient;Excellent resistance to wind erosion performance;Continuous production, uniform fiber distribution, stable performance;Excellent sound-absorbing noise reduction performance.
Third: steel making, casting industry (particles of silicon carbide, silicon carbide, silicon carbide, silicon carbide powder)
Silicon carbide as steelmaking deoxidizer can make molten steel quality is stable, and has fine grains, remove steel always harmful impurities, after using molten steel casting temperature, casting are of good quality and low cost per unit.
Silicon carbide can be all alternative ferrosilicon and recarburizer FeALSi dosage decreased, which can effectively reduce the cost of steelmaking.
Decomposition of silicon carbide at high temperature and oxidation is exothermic reaction process, positive pressure in the furnace is strong, and can guarantee lower sulfur content.
Fourth: photovoltaic industry, polishing, grinding, high-tech research and development, and other industries (silicon carbide micro powder)
Silicon carbide powder is mainly used for refractory products manufacturing, and foam ceramic industry, solar silicon original cutting, crystal cutting, grinding, car engine manufacturing, special coating industry, plastics modification, desulfurization, power supply, environmental protection industry, etc.
