Metallurgical Grade Silicon Carbide

Our silicon carbide crude is produced by mixing high purity quartz sand and best China's No. 03 anthracite in an electric resistance furnace at temperatures around 2500°C. Once the crude has been produced, it undergoes processing crushing, milling and precision water classification process and air flow classification into finished grains and powders.

 

Applications:

 

In metallurgical applications, silicon carbide can be used in cast iron foundries for induction and cupola furnaces. It is use in the 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. Silicon carbide is also used in the steelmaking industry as deoxidizing and exothermic agent at ladle and BOF furnaces respectively.

 

Silicon carbide for metallurgical applications is available in various SiC quality grades and particle shape and size fractions. These characteristics are adapted to the specific metallurgical application and customer need.

• Good wear, corrosion resistance and resisting performance,resist to shock.
• Cost-effective substitute for ferrosilicon.
• Costs less than ferrosilicon and carbon combination.
• No dust nuisance while feeding the material and speed up the reaction.
