INQUIRY

Ferrosilicon is used as an alloying agent. It is widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in the production of ferroalloys and the chemical industry. An iron alloy composed of iron and silicon (silicon, steel, coke as raw materials, silicon reduced at a high temperature of 1500-1800 degrees is melted in the molten iron to form a ferrosilicon alloy). It is an important alloy variety in the smelting industry.

It used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain the steel with qualified chemical composition and ensure the quality of the steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large. Deoxygenation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel. Therefore, in smelting structural steel (containing silicon 0.40-1.75%), tool steel (containing SiO.30-1.8%), spring steel ( When containing SiO.40-2.8%) and silicon steel for transformers (containing 2.81-4.8% of 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 the molten steel is an effective new technology to improve the quality of steel, reduce costs, and save iron. It is especially suitable for the deoxidation requirements of continuous casting steel. Practice has proved that ferrosilicon not only meets the deoxidation requirements of steelmaking, but also has the advantages of desulfurization performance, large specific gravity and strong penetration.

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