Application: A. Used as oxidization and alloy in steel making industry. The ferro silicon powder can produce plenty of heat when firing in high temperature, so it used to be as heat material to improve the quality and create rate.
B. Used as generating agent and globalizing agent in cast iron industry.
C. Used as reducing agent in processing iron alloy making.
D. The ferro silicon powder which treat by grinding and pulverization can be as suspension in mine option industry and paint in welding rod making industry.
Packing: In 1MT bags
