Ferro Silicon is widely used in the steel industry, foundry industry, and other industrial production. Recent market Ferro Silicon movements keeps stable. Ferro Silicon is indispensable deoxidizer in steel industry. Torch in steel, FeSi is used to precipitate DNA and the DNA of diffusion. Adobe iron alloy as agent is used in steelmaking. Adding a certain amount of silicon in steel, it can significantly improve the strength of steel, hardness and elasticity.It improves the steel permeability, reducing transformer steel hysteresis losses.
