Silicon Carbide For Metallurgical
Metallurgical Application of Silicon Carbide
In the metallurgical industry, black silicon carbide is used in the production of iron and steel. It can be added to the molten metal to enhance its properties and improve the quality of the final product.
Due to its hardness second only to diamond, it has strong wear resistance and is an ideal material for wear-resistant pipes, impellers, pump chambers, cyclones, and mining hopper linings. Its wear resistance is more than 5 times the service life of cast iron and rubber, and it is also one of the ideal materials for aviation flight runways.

Applications of Silicon Carbide as Refractory Material
Deoxidation Alloying
Adding molten steel as a deoxidizer will help improve the quality of molten steel.
Deoxidizer for Refining Outside the Furnace
It can be used as a deoxidizer for steelmaking and an improver for cast iron structure.
Steelmaking Temperature-Raising Agent
In the steelmaking process, when the carbon temperature is not coordinated, the temperature of the molten steel can be increased by adding sic.
Nonferrous Metal Smelting
Due to its high-temperature resistance, high strength, good thermal conductivity and impact resistance, it is often used in non-ferrous metal smelting.
Steel Production
Silicon carbide can be used in converter steelmaking to replace part of ferrosilicon to deoxidize molten steel.
Heating Material
Due to its high-temperature resistance and good thermal conductivity, it can be used as high-temperature indirect heating materials, such as thermocouple protection tubes.
