Products Description
Ferro Silicon (FeSi) is a vital ferroalloy mainly composed of silicon and iron, produced by smelting silica and coke in an electric furnace. It is widely used in the steelmaking, foundry, and metallurgical industries as a deoxidizer, inoculant, and alloying agent. With its ability to remove oxygen, improve fluidity, and enhance mechanical properties, Ferro Silicon ensures higher purity steel and better quality cast iron.
