Metallurgy grade black silicon carbide SiC 65-90%
Silicon carbide, a synthetic raw materials, the Si02 content of not less than 97% natural silica (silica sand) and coke (or anthracite) as the basic raw material, add a pinch of salt and wood chips, 2000-2500 ~ C temperature resistance furnace in the synthesis.
Purposes:
1, the application of non-ferrous metal smelting industry
Silicon carbide has a high temperature, high strength, good thermal conductivity, impact resistance for high temperature indirect heating materials, such as Kennedy pot distillation furnace. Distillation furnace trays, aluminum reduction cell, copper melting furnace lined with zinc powder furnace arc plate, thermocouple protection tubes.
2, the steel industry in the application
The use of silicon carbide corrosion resistance. Thermal shock and wear resistance. Thermal conductivity and good for the large-scale blast furnace lining to improve the service life.
3, metallurgy and mineral processing industry applications
Silicon carbide hardness only to diamond, has strong abrasion resistance, wear-resistant pipe, impeller, pump room, whirlpool, ore bucket lined with the ideal material, the wear resistance of cast iron. One of the rubber life of 5-20 times, is also an ideal material for aviation runway.
