High-carbon ferrosilicon is also called silicon-carbon alloy. Its main elements are silicon and carbon. The common indicators of silicon and carbon are 3515, 4515, 5515 and 6515. It can be seen that its carbon content is relatively high, so it also has a high carbon content. Ferrosilicon, high carbon ferrosilicon is often used in steelmaking furnaces.
High carbon silicon is a new type of strong composite deoxidizer that can also be used in the smelting of general steel and ordinary carbon steel. Its main elements are silicon and carbon. The silicon element has high activity, fast reaction and can increase the furnace temperature. Therefore, high-carbon silicon can replace traditional temperature-raising agents that require higher prices when making steel in converters and open-hearth furnaces.
High-carbon ferrosilicon is a commonly used deoxidizer with the following advantages: Carbon and silicon are important elements that determine the function of steel. High-carbon silicon can not only react with oxygen in molten steel to achieve a deoxidizing effect, but the remaining carbon and silicon are not oxidized. It can also be dissolved in molten steel to increase silicon and carburization. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of the steel. It has the effect of killing two birds with one stone. Steelmaking needs to be deoxidized, and the chemical affinity between silicon and oxygen is very large. Therefore, ferrosilicon is a strong deoxidizer for steelmaking and is used for precipitation and diffusion deoxidation.
