Silicon Carbide (Metallurgical Grade Black SiC)
Metallurgical silicon carbide is synthesized with quartz sand and petroleum coke at ultra-high temperature in resistance furnace. It appears as black grit and powder with excellent high temperature resistance and strong reducing activity.
Advantages
Dual functions of deoxidation, silicon and carbon inoculation;
Exothermic reaction heats molten metal, saves power consumption;
Cost-effective substitute for ferrosilicon and carburizer;
Refine grain structure, reduce blowholes and shrinkage defects for castings;
Multiple sizes available: lumps, grits and powder as customer's request.
Applications
Deoxidizer for EAF & converter steelmaking
Inoculant for ductile iron & grey cast iron
Raw material for refractory taphole clay, castables
Abrasive & sandblasting material
