Application
Ferrosilicon is widely used in steel industry, foundry industry and other industrial production.Ferrosilicon is an essential deoxidizer in steel-making industry. In torch steel, 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 steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, and reduce the hysteresis loss of transformer steel. General steel contains 0.15% - 0.35% silicon, structural steel 0.40% - 1.75% silicon, tool steel 0.30% - 1.80% silicon, spring steel 0.40% - 2.80%, stainless acid resistant steel 3.40% - 4.00%, heat resistant steel 1.00% - 3.00%, silicon steel 2% - 3% or higher.High silicon ferrosilicon or siliceous alloys are used as reducing agents in the ferroalloy industry to produce low-carbon ferroalloys. Adding ferrosilicon into cast iron can be used as inoculant for nodular cast iron, prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.
