Silicon carbide has a variety of specifications 75,80,88,90,97,98... has corrosion resistance, high temperature resistance, high strength, good thermal conductivity, impact resistance and other characteristics. It has many important roles in steelmaking. It can speed up the steelmaking speed, and easy control of chemical composition, improve the quality of steel.
1. Deoxygenation
In the process of steelmaking, it can react with the oxygen in the steel water to produce carbon monoxide gas and silicon oxides, thus reducing the oxygen content in the liquid steel.
2. Add silicon and add carbon
In the process of deoxygenation, the silicon and carbon elements in silicon carbide will be dissolved into the liquid steel under certain conditions, playing the effect of increasing silicon and carbon.
3. Improve the steel organization and performance
Refine the grain；Enhance steel wear resistance and heat resistance, improve steel durability and service life.
4. Reduce the oxidation and decarbonization of steel
Silicon carbide can form a stable oxide film on the surface of the steel, preventing the steel from contacting with the oxygen in the air, thus preventing the oxidation of the steel.
5. Improve the thermal efficiency of steel
Silicon carbide can form a layer of silicon carbide film on the surface of steel, improve the thermal conductivity and heat transfer of steel, so as to improve the thermal efficiency of steel and reduce the energy consumption in the steelmaking process.
6. Reduce steelmaking costs
Silicon carbide has good deoxygenation and silicon effect at the same time, the price is relatively low
