What are the uses and production of ferro silicon?

Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is also called ferrosilicon. It is an iron-silicon alloy made from coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. It is widely used in steel industry, foundry industry and other industrial production.
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 for steelmaking for precipitation and diffusion. deoxidation.
Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of the steel. Therefore, it is widely used in smelting structural steel (containing 0.40-1.75% silicon), tool steel (containing SiO.30-1.8%), and spring steel. (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 penetrating power.
