Introduction of ferro silicon
Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.
