• Improving the strength, hardness, and elasticity of steel: When smelting structural steel, tool steel, spring steel, and silicon steel for transformers, the use of silicon iron powder as an alloying agent can significantly improve the strength, hardness, and elasticity of steel.
• Promoting graphite precipitation and spheroidization: In the cast iron industry, silicon iron powder is used as an inoculant and spheroidizing agent, which can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite, which is particularly important in the production of ductile iron.
• As a reducing agent: In the production of ferroalloys, ferrosilicon powder is used as a reducing agent due to its high chemical affinity with oxygen and low carbon content. This is particularly important in the production of low-carbon ferroalloys.
• Other uses: Fine ground or atomized silicon iron powder can be used as a suspended phase in the mineral processing industry, and can also be used as a coating for welding rods in the welding rod manufacturing industry. In addition, high silicon iron powder can be used in the chemical industry to manufacture products such as silicone.
