The role of silicon carbide

Silicon carbide industrial system is high-quality quartz sand and petroleum coke in a resistance furnace refining. Lian obtained silicon carbide blocks, crushing, acid washing, magnetic separation and screening or water election into various size products.
SiC as chemical stability, high thermal conductivity, thermal expansion coefficient, good wear resistance, except for the abrasive used, there are many other uses.
For example: a special process of the silicon carbide powder coating on the turbine impeller or the inner wall of the cylinder, to improve the wear resistance and extended life of 1 to 2 times.
Made for advanced refractory, thermal shock resistance, small size, light in weight, high strength, good energy saving effect.
Low-grade silicon carbide (SiC-containing about 85%) is an excellent oxygen scavenger, it can accelerate the speed steel, and facilitate control of chemical composition and improve the quality of steel. In addition, silicon carbide heating element is also used extensively for production of silicon carbide.
