DESCRIPTION
Ferrosilicon is an essential deoxidizer in the steelmaking industry. Ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Ferrosilicon is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, increase the magnetic permeability of the steel, and reduce the hysteresis loss of the transformer steel.
