With the development of industry, black silicon carbide is used as an additive in various industries and plays an important role in improving product quality and production process. The foundry industry has become an important item in the modern industry. Black silicon carbide has played an important role in this industry. With the change of technology, it has attracted more and more people’s attention.

The role of black silicon carbide as an additive: Good thermal conductivity and thermal stability, used as a heat exchanger, reducing fuel consumption by 20%, saving fuel by 35%, increasing productivity by 20-30%, especially for the internal discharge and transportation pipelines of mine dressing plants, black silicon carbide resistant The degree of grinding is 6 to 7 times that of general wear-resistant materials.

The use of black silicon carbide has high temperature resistance, high strength, excellent thermal conductivity, impact resistance, and can be used as high-temperature direct heating materials, such as hard pot distillation furnaces, rectification furnace trays, aluminum electrolytic cells, copper melting furnace linings, and zinc powder furnaces. Arc plate, thermocouple maintenance tube, etc. The use of steel, corrosion resistance, thermal shock resistance and wear resistance, good heat conduction characteristics, used for large blast furnace lining improves service life.



The role of black silicon carbide: The use of black silicon carbide is helpful to improve product quality, because silicon carbide can effectively increase fluidity, stabilize the composition of molten iron, and avoid segregation. This can reduce the wall thickness sensitivity, make the structure dense and the cutting surface bright.

Black silicon carbide can increase the nucleation ability of casting graphite, effectively and significantly improve the machinability of castings, improve mechanical properties, and for silicon carbide, it can avoid the separation of carbides, increase the amount of ferrite, and reduce the white appearance There are significant.

Black silicon carbide can also be a powerful deoxidizer, which can purify molten iron, reduce the amount of nodulizer added, and improve the nodularization rate, which is of great help in saving production costs.
