SILICON CARBIDE :
Silicon carbide is used for the de-oxidation and re-carburation of cast iron and steel in foundries. Metallurgical grade Silicon Carbide grain is a unique material for use in the production of iron and steel. It is used in the foundry industry for electric furnace production of gray, ductile, and malleable iron. It is an excellent source of carbon and silicon, promoting nucleation and rendering the iron more responsive to inoculation, deoxidizing the iron, which enhances furnace lining life.
