Industrial use of ferrosilicon powder

Ferrosilicon powder is an alloy of silicon and iron that is then ground into a powdery substance and used as a deoxidizer in steelmaking and iron making.

Ferrosilicon powder is widely used in steelmaking and cast iron industry, so ferrosilicon powder is also one of the ferroalloys widely purchased by various manufacturers, so today we will introduce the main role of ferrosilicon powder!

Role one, ferrosilicon powder is often used as a deoxidizer and alloy agent

In the steelmaking industry, in order to obtain qualified chemical composition of steel and ensure the quality of steel, in the later stage of steelmaking must be deoxidized, the chemical affinity between silicon and oxygen in ferrosilicon powder is very large, so ferrosilicon powder is a strong deoxidizer for precipitation and diffusion deoxidization. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel.

Function two, ferrosilicon powder can be used as a reducing agent in the production process of ferroalloy

In the process of ferroalloy production , the chemical affinity between silicon and oxygen is very high and the carbon content of high silicon ferrosilicon powder is very low. Therefore, high silicon ferrosilicon powder (or silicon alloy) is a commonly used reducing agent in the production of low carbon ferroalloy in ferroalloy industry.

Function three, iron industry iron silicon powder is often used as inoculant and spheroidizing agent

Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt. It has excellent casting performance and much better earthquake resistance than steel. In particular, the mechanical properties of ductile iron are equal to or close to those of steel. Adding a certain amount of ferric silicon powder to cast iron can prevent the formation of carbide in iron and promote the precipitation and spheroidization of graphite, so in the production of ductile iron, ferric silicon is an important inoculant (help to precipitate graphite) and spheroidization agent.
