Use of silicon carbide

Silicon carbide is also known as gold steel sand or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (production of green silicon carbide needs to add salt) and other raw materials in the resistance furnace by high temperature smelting. At present, our industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two kinds, are hexagonal crystal, specific gravity is 3.20 ~ 3.25, microhardness is 2840 ~ 3320kg/mm2.

The 5 main uses of silicon carbide

1. Application of non-ferrous metal smelting industry

The use of silicon carbide has high temperature resistance, high strength, good thermal conductivity, impact resistance, as high temperature indirect heating material, such as a solid tank distillation furnace. Distillation furnace tray, aluminum electrolyzer, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tube, etc.

2, steel industry applications

Use the corrosion resistance of silicon carbide. Resistant to heat shock and wear. Good thermal conductivity, used for large blast furnace lining to improve the service life.

3, the application of metallurgy and mineral processing industry

Silicon carbide hardness is second only to diamond, with strong wear-resisting performance, is wear-resisting pipeline, impeller, pump chamber, cyclone, ore bucket lining ideal material, its wear-resisting performance is cast iron. Rubber has a service life of 5-20 times, and is also one of the ideal materials for aviation flight runway.

4, building materials ceramics, grinding wheel industry applications

Using its thermal conductivity. Heat radiation, high thermal strength characteristics, manufacturing sheet kiln, not only can reduce the capacity of kiln, but also improve the capacity of kiln and product quality, shorten the production cycle, ceramic glaze baking sintering ideal indirect materials.

5, energy saving applications

With GOOD THERMAL CONDUCTIVITY and thermal stability, as a heat exchanger, the fuel consumption is reduced by 20%, the fuel is saved by 35%, and the productivity is increased by 20-30%. In particular, the mine concentrator with the discharge pipeline put in, its wear-resisting degree is 6-7 times of the ordinary wear-resisting material.
