Ferrosilicon is widely used in steel industry, foundry industry and other industrial production. Ferrosilicon is an essential deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to the steel can significantly increase the strength, hardness and elasticity of the steel, increase the magnetic permeability of the steel, and reduce the hysteresis loss of the transformer steel.
A ferrosilicon briquette is prepared, including ferrosilicon raw materials and a binder. The ferrosilicon raw materials are ferrosilicon powder or a mixture of ferrosilicon powder and metal silicon powder; the content of silicon in the ferrosilicon powder is 72-75% .
