What is ferrosilicon slag?

Ferrosilicon slag is the residue of ferrosilicon smelting, which can be used effectively again as secondary regenerating material. Ferrosilicon slag is widely used in steel industry, foundry industry and other industrial production is widely used.

It is often used as deoxidizer and alloying agent in foundry industry. This is because silicon and oxygen have a strong affinity can be combined into silicon dioxide, so ferrosilicate slag is often used in casting as a deoxidizer. Because SiO2 generation can release a lot of heat, in the deoxidation at the same time to improve the temperature of molten steel is also very beneficial, so adding a certain amount of silicon in the steel, can effectively enhance the strength, hardness and elasticity of steel, so ferro-silicon slag is also used as an alloying agent.

In steelmaking industry, ferrosilicate slag is used for precipitation deoxidation and diffusion deoxidation. Adding a certain amount of silicon to steel can improve the strength, hardness and elasticity of steel, upgrade the magnetic permeability of steel, and reduce the hysteresis loss of transformer steel. In addition, high silicon ferrosilicon slag or siliceous alloy can also be used as reducing agent in the production of low carbon ferroalloy in the ferroalloy industry.
