Ferrosilicon inoculants are additives commonly used in metal casting processes, primarily to adjust metal composition and improve casting quality. They contain elements such as silicon and iron, which effectively improve casting performance during the casting process. Specifically, ferrosilicon inoculants can eliminate defects such as shrinkage cavities and sand holes in castings, improve the mechanical properties and surface finish of castings, and increase casting density.
During the casting process, the main function of ferrosilicon inoculants is to improve the strength, toughness, and wear resistance of cast iron by promoting graphitization, reducing white iron tendency, improving graphite morphology and distribution, increasing the number of eutectic clusters, and refining the matrix structure. These improvements contribute to enhancing the overall performance and service life of castings.
In the cast iron industry, ferrosilicon is an important inoculant and spheroidizing agent. It helps precipitate graphite, improves the microstructure of cast iron, and enhances its mechanical and machinability. Ferrosilicon inoculants play a crucial role in the casting process, improving casting quality and performance by adjusting metal composition and enhancing casting properties.
