Calcium Silicon Alloy For Steelmaking

 

Calcium Silicon (CaSi) is a compound alloy primarily composed of calcium, silicon, and iron, widely used as a deoxidizer and desulfurizer in the steelmaking industry. It also serves as an inoculant and modifier in cast iron production. With excellent deoxidation and desulfurization capabilities, Calcium Silicon significantly improves the quality and performance of steel and cast iron products.
