High carbon ferrosilicon is ferrosilicon with a large carbon content. High carbon ferrosilicon is often used in steelmaking furnaces. For example, as a new type of strong composite deoxidizer, it can also be used for the tempering of general steel, alloy steel and special steel. In addition, as a temperature-raising agent, it can replace the higher-priced traditional temperature-raising agent required in converter and open-hearth steelmaking.
High-carbon ferrosilicon is a commonly used deoxidizer and has the following advantages: no hydrogen source is generated during the deoxidation process, ensuring safety and reliability; carbon and silicon are important elements that determine the function of steel, and high-carbon ferrosilicon can not only react with oxygen in molten steel To achieve the deoxidation effect, the remaining unoxidized carbon and silicon can also be dissolved in the molten steel to increase silicon and carburization, achieving the effect of killing two birds with one stone. In order to obtain steel with qualified chemical composition and ensure the quality of steel, steelmaking must be deoxidized. 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.
