Ferrosilicon powder

Product
Description

Ferrosilicon powder: an iron alloy composed of iron and silicon, and then ground into a powdery substance, which is used as a deoxidizer for steelmaking and ironmaking.

1. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel. Therefore, when smelting structural steel, tool steel, spring steel, and silicon steel for transformers, ferrosilicon is also used as an alloying agent. . It is used as an inoculant and a nodularizing agent in the 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. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and balls. chemical agent.

APPLICATION

3. Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is very high, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.

4. Not only the chemical affinity between silicon and oxygen is very large, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.

5. Use in other aspects. The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.

6. It can be used as a coating for welding rods in the welding rod manufacturing industry. High-silicon ferrosilicon is used in the chemical industry to manufacture products such as silicone.
