    Used as deoxidizer and alloy agent in steelmaking industry. In order to obtain qualified chemical composition of steel and ensure the quality of steel, in the last stage of steel must be deoxidized, the chemical affinity between silicon and oxygen is very large, so iron silicon is a strong deoxidizer for steel precipitation and diffusion deoxidization. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, so when smelting structural steel (containing silicon 0.40-1.75%), tool steel (containing SiO.30-1.8%), spring steel (containing SiO.40-2.8%) and transformer silicon steel (containing Silicon 2.81-4.8%), Ferrosilicon is also used as an alloying agent. At the same time, it is an effective new technology to improve the quality of steel, reduce the cost and save the use of iron by improving the shape of inclusions and reducing the content of gas elements in liquid steel. It is especially suitable for deoxidation of molten steel in continuous casting. Practice has proved that ferrosilicon not only meets the deoxidation requirements of steel making, but also has desulfurization performance and has the advantages of heavy ratio and strong penetration.

    In addition, in the steelmaking industry, the use of ferrosilicon powder at high temperature can release a lot of heat this characteristic, often used as ingot cap heating agent to improve the quality and recovery of steel ingot
