Ferrosilicon is widely used in steelmaking, casting and other industrial production. In the field of steelmaking, ferrosilicon is used as a deoxidizer and alloying agent, playing the role of precipitation deoxidation and diffusion deoxidation.
Adding a certain amount of iron-silicon to steel can significantly improve the strength, hardness, elasticity and permeability of steel.

Iron Silicon
Ferrosilicon is used as deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out during the steelmaking stage.
The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong 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. 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.
In addition, in the steelmaking industry, ferrosilicon powder is often used as a heating agent for steel ingot caps to improve the quality and recovery rate of steel ingots by taking advantage of the fact that ferrosilicon powder can release a large amount of heat when burned at high temperatures.
