The role of ferrosilicon in steelmaking:
Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer used in steelmaking. Precipitation and diffusion deoxidation.
The role of ferrosilicon in cast iron:
Used as inoculant and spheroidizing agent in the cast iron industry. 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. Adding a certain amount of ferrosilicon to cast iron can prevent the iron from It forms carbides and promotes the precipitation and spheroidization of graphite. Therefore, ferrosilicon is an important inoculant and spheroidizing agent in the production of ductile iron.
The role of ferrosilicon in ferroalloy production:
Used as reducing agent in ferroalloy production. Not only is the chemical affinity between silicon and oxygen very high, but the carbon content of high-silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon is a commonly used reducing agent in the ferroalloy industry when producing low-carbon ferroalloys.
The main use of ferrosilicon natural blocks is as an alloying agent in steel production. It can improve the hardness, strength, and corrosion resistance of steel, and can also improve the weldability and processability of steel.
Ferrosilicon granules, referred to as ferrosilicon inoculants, are mainly used in cast iron. In the cast iron industry, it is cheaper than steel, easy to melt and smelt, has excellent casting properties, and has much better earthquake resistance than steel. In particular, the mechanical properties of ductile iron reach or are close to those of steel.
High silicon ferrosilicon powder has very low carbon content. Therefore, high-silicon ferrosilicon powder (or silicon alloy) is a commonly used reducing agent in the ferroalloy industry when making low-carbon ferroalloys. Use in other ways. Ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. In the welding rod manufacturing industry, it can be used as a coating for welding rods. High silicon ferrosilicon powder can be used in the chemical industry to manufacture silicone and other products.
