Products Description
Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the final stage of steelmaking must be deoxidized, the chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for precipitation and diffusion in steelmaking. Add a certain amount of silicon to the steel, It 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 Si0.40-2.8%) and transformer silicon steel (containing silicon 2.81-4.8%), ferrosilicon is also used as an alloying agent.
At the same time, 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 cost and save iron. It is especially suitable for continuous casting steel deoxidation requirements. Practice has proved that ferrosilicon not only meets the deoxidation requirements of steelmaking, but also has desulfurization performance and has the advantages of heavy ratio and strong penetration.
