Uses of Ferrosilicon:

1. 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 steelmaking stage. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer in steelmaking for precipitation and diffusion deoxidation. . Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel. When containing SiO.40-2.8%) and silicon steel for transformers (containing 2.81-4.8% silicon), ferrosilicon is also used as an alloying agent. At the same time, improving the shape of inclusions and reducing the content of gas elements in molten steel is an effective new technology to improve steel quality, reduce costs and save iron. It is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that ferrosilicon not only meets the deoxidation requirements of steelmaking, but also has desulfurization performance and has the advantages of large specific gravity and strong penetration.

In addition, in the steelmaking industry, ferrosilicon powder can release a lot of heat at high temperature, and it is often used as a heating agent for steel ingot caps to improve the quality and recovery rate of steel ingots.

2. It is used as an inoculant and a nodularizing 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, and has excellent casting properties and much better shock resistance than steel. In particular, ductile iron, its mechanical properties are at or close to those of steel. Adding a certain amount of ferrosilicon 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 (helping to precipitate graphite) and spheroidizing agent. .

3. It is used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is very high, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.

4. 75# ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon process of magnesium smelting. The magnesium in CaO.MgO is replaced, and about 1.2 tons of ferrosilicon are consumed for each ton of metal magnesium produced. Magnesium metal production plays a big role.

5. Use in other aspects. The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as a coating for welding rods in the welding rod manufacturing industry. High-silicon ferrosilicon is used in the chemical industry to manufacture products such as silicone.

Among these uses, the steelmaking industry, the foundry industry and the ferroalloy industry are users of ferrosilicon. Together, they consume about 90% more ferrosilicon. Among various grades of ferrosilicon, 75% ferrosilicon is currently widely used. In the steelmaking industry, about 3-5kg of 75% ferrosilicon is consumed for every 1t of steel produced.
