Ferrosilicon powder is an iron alloy composed of silicon and iron, which is then ground into a powdery substance and used as a deoxidizer in steelmaking and ironmaking.
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. So today, a professional ferroalloy manufacturer will introduce to you the main functions of ferrosilicon powder!
Function 1. Ferrosilicon powder is often used as a 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 carried out in the later stages of steelmaking. The chemical affinity between silicon and oxygen in ferrosilicon powder is very large, so ferrosilicon powder It is a powerful deoxidizer for steelmaking 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 the steel.
Function 2: Ferrosilicon powder can be used as a reducing agent in the production process of ferroalloys
In the ferroalloy production process, ferrosilicon powder not only has a high chemical affinity between silicon and oxygen, but also 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 ferroalloy industry when producing low-carbon ferroalloys.
Function 3. Ferrosilicon powder in the cast iron industry is often used as an 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 properties and is much better than steel in earthquake resistance. In particular, the mechanical properties of ductile iron reach or are close to those of steel. Adding a certain amount of ferrosilicon powder to cast iron can prevent the formation of carbides in the 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 spheroidization. agent.
