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.
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.

In addition, in the steelmaking industry, silicon balls can emit a large amount of heat when sintered at high temperatures, and are often used as exothermic agents for ingot caps to improve the quality and recovery of ingots. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, improve the magnetic permeability of the steel, and reduce the hysteresis loss of the transformer steel. Silicon balls can be used as an inoculant for ductile iron when added to cast iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.
