Silicon carbide(silicon carbide block), also known as emery or refractory sand, has a chemical formula of SiC and is a very widely used inorganic substance. There are two types of silicon carbide obtained by industrial production, namely black silicon carbide and green silicon carbide.
silicon carbide is produced in the same way as black silicon carbide, but with different requirements for raw materials. silicon carbide is made of petroleum coke and high-quality silica as the main raw material. It is added with salt as an additive and is smelted by high-temperature resistance furnace. The crystallized smelt is high in purity and hardness, and its hardness is between corundum and diamond. Mechanical strength Higher than corundum.
Green silicon carbide can be divided into a flat shape by grinding wheels, bevel wheels, cylindrical wheels, cup wheels, grinding plate and the like; binding agents can be divided by a ceramic wheel, resin wheel, a rubber wheel, the metal wheel and the like. The characteristic parameters of the grinding wheel mainly include abrasive, viscosity, hardness, bonding agent, shape and size.
Silicon carbide is an ideal compound deoxidizer, desulfurizer.ca and si has a strong affinity with oxygen. Especially calcium, not only has a strong affinity with oxygen , and sulfur, nitrogen has a very strong affinity.Silicon carbide is also suitable for practicing BOF steel plant with a warming agent, also used for cast iron and ductile iron inoculant production of addictives.
