What is metallurgical silicon carbide?
Metallurgical silicon carbide is a high-purity silicon carbide material in the metallurgy industry. It is suitable for carburizer and deoxidizer in the manufacture of cast iron, malleable cast iron and ductile iron.
Silicon carbide is produced by the reaction of petroleum coke and silica sand in a smelting furnace. It is a mixture containing silicon and carbon obtained by the reaction of petroleum coke and quartz sand. The resulting product obtained from this mixture is silicon carbide. After crushing and seiving, obtain the required particle size. Metallurgical silicon carbide has a silicon carbide content of 85-98% and works widely in modern steelmaking and metallurgy.
Metallurgical silicon carbide (SiC) can help cast iron inoculation. 85% purity SiC is suitable for the production of gray cast iron. 88-95% SiC fraction is more suitable for the smelting of ductile cast iron.
Advantages of silicon carbide in metallurgy field:
- As a carbon source and silicon source, the metallurgical SiC works as an additive and reduce the overall cost of steelmaking.
- More economical than ferrosilicon and higher structure.
- Silicon carbide can provide more control over the ironmaking process due to its inoculation and deoxidation advantages
- Increased activity of scrap steel in the feed
- Stable mechanical properties
