Ferrosilicon: an ferroalloy of iron and silicon, used as a deoxidizer in steel and iron making
USES of ferrosilicon:
1. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, so iron silicon is also used as alloy agent in the smelting of structural steel, tool steel, spring steel, and silicon steel for transformers.Used as inoculant and spheroidizing agent in cast iron industry.
2. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite, so in the production of nodular cast iron, ferrosilicon is an important instillation agent (to help the precipitation of graphite) and spheroidization agent.
3. Used as reducing agent in ferroalloy production.The chemical affinity between silicon and oxygen is great, and the carbon content of high silicon ferrosiliconis very low.Therefore, high silicon ferrosilicon (or siliceous alloy) is a reducing agent commonly used in the production of low carbon ferroalloy in ferroalloy industry.
4. Not only the chemical affinity between silicon and oxygen is great, but also the carbon content of high silicon ferrosilicon is very low.Therefore, high silicon ferrosilicon (or siliceous alloy) is a reducing agent commonly used in the production of low carbon ferroalloy in ferroalloy industry.
5. Other USES.Pulverized or atomized ferrosilicon powder can be used as suspended phase in mineral processing industry.
6. Can be used as welding electrode coating in the welding electrode manufacturing industry.High silicon ferrosilicon can be used in the chemical industry to make products such as silicone.

Low ferrosilicon USES:
1. Low ferrosilicon can replace some ferrosilicon alloys to deoxidize silicon and iron, effectively control the temperature of molten steel, and do not affect the absorption rate of other alloys in the process of use;
2. Low ferrosilicon water can reduce the amount of ore and scrap, ensure the normal heating rate of the molten pool metal, so as to achieve less slag steelmaking, reduce lime consumption and improve the metal yield;
