the main role of ferrosilicon powder in all walks

Ferrosilicon powder is widely used in the steelmaking and cast iron industries, so ferrosilicon powder is also one of the ferroalloys widely purchased by various manufacturers. Then today, professional ferroalloy manufacturers will introduce the main role of ferrosilicon powder for everyone!


  Function 1. Ferrosilicon powder is often used as deoxidizer and alloying agent

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

 Function 2. Ferrosilicon powder in cast iron industry 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, has excellent casting performance and much better seismic resistance than steel. Especially for ductile iron, its mechanical properties are at or close to those of steel. Adding a certain amount of ferrosilicon powder 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 (helps precipitate graphite) and spheroidization Agent.

Function 3. Ferrosilicon powder can be used as a reducing agent in the production process of ferroalloys

Ferrosilicon powder not only has a large chemical affinity between silicon and oxygen, but also has a low carbon content in high-silicon ferrosilicon powder. Therefore, high silicon ferrosilicon powder (or silicon alloy) is a reducing agent commonly used in the production of low carbon iron alloys in the ferroalloy industry.

The above are the main uses of ferrosilicon powder in various industries. Hope to help you better understand the common uses of ferrosilicon powder!
