2.Silicon balls are a metallurgical material that needs to be added in steelmaking. By adding an appropriate amount of silicon balls, the content of non-metallic inclusions in the steel can be reduced, the distribution is suitable, and the shape is suitable, so as to ensure that the properties of the steel can reach the standard. fine-grained structure. In fact, silicon balls can not only improve the quality of steel, but also improve production efficiency, reduce costs, and provide higher economic benefits for steel mills.
3.In the steelmaking industry, silicon balls are mainly used as a deoxidizer and an alloying agent. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out during steelmaking. The chemical affinity between silicon and oxygen is very large, so silicon ball is a strong deoxidizer in steelmaking for precipitation and diffusion deoxidation. . Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel.
