What are the main uses and functions of ferrosilicon
Aug 28, 2023
The main use of ferrosilicon Ferrosilicon is widely used in iron and 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. Ferrosilicon is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, increase the magnetic permeability of steel, and reduce the hysteresis loss of transformer steel.
The role of ferrosilicon is deoxidizer, alloy agent and reducing agent. The role of silicomanganese is deoxidizer, alloy agent and desulfurizer. Silicon can significantly improve the elasticity and magnetic permeability of steel. Manganese can reduce the brittleness of stiffness, improve the heat treatment performance of stiffness, and increase the strength, hardness and wear resistance of stiffness. Silicon-manganese alloys can deoxidize and potentially increase the manganese content in the finished steel and increase the strength of the steel. Therefore, the proportion of silicon-manganese alloy used as a deoxidizer is gradually higher than that of ferrosilicon. As the saying goes, "steel cannot be made without manganese". At present, the role of manganese in the steel production process cannot be replaced by other elements.
