ferrosilicon powder

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

The use of ferrosilicon powder:

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 transformer silicon steel, ferrosilicon is also used as an alloying agent. . Used as inoculant and nodulizer in the cast iron industry.

 

2. Adding a certain amount of ferro silicon 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 (to help precipitate graphite) and balls。

3. Used as a reducing agent in the production of ferroalloys. Not only is the chemical affinity between silicon and oxygen great, but 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 iron alloys in the ferroalloy industry.

4. Not only the chemical affinity between silicon and oxygen is very large, but 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 iron alloys in the ferroalloy industry.

5. Other uses. The ground or atomized ferrosilicon powder can be used as a suspended phase in the beneficiation industry.

6. Can be used as electrode coating in electrode manufacturing. High-silicon ferrosilicon can be used to make silicone and other products in the chemical industry.
