Silicon Carbide for Casting
Silicon carbide for casting features high hardness, excellent wear resistance, and high-temperature tolerance. These advantages make silicon carbide widely used in producing various molds and cutting tools for cast iron products. XLS Metals is an experienced supplier of silicon carbide, equipped with an independent R&D laboratory and advanced production facilities, dedicated to providing high-performance silicon carbide for users in the casting industry.
The chemical composition of silicon carbide for casting primarily consists of silicon (Si) and carbon ©, with Si making up 70% and C 30%. However, this ratio may vary slightly depending on production processes and brand specifications. Typically, using silicon carbide as a raw material for producing different cast iron types can significantly enhance casting quality, extend service life, and reduce casting costs. Furthermore, due to its high hardness and wear resistance, silicon carbide serves as a crucial raw material for manufacturing grinding wheels and cutting fluids, effectively improving the surface quality of castings and boosting production efficiency.
During the casting process, the amount of silicon carbide added must be strictly calculated. The addition of silicon carbide for casting generally represents 2% to 10% of the molten iron, with a stable absorption rate of around 90%. The application of silicon carbide in foundry industry is very extensive, and its addition amount varies according to the casting process, performance requirements, and various specifications. When adding silicon carbide, it should be securely packaged in woven bags and introduced into the molten iron, with precise control over the sequence and melting process to ensure optimal performance of silicon carbide in the casting procedure.
Silicon carbide supplied by XLS Metals for the casting sector not only effectively deoxidizes the molten iron but also enhances its reducing properties, preventing the precipitation of carbides and promoting the density and wear resistance of cast iron. When producing ductile iron, our silicon carbide for casting typically exhibits high spheroidization performance, significantly increasing the spheroidization rate and facilitating the formation of type A graphite, which enhances the overall quality and performance of the product. With its high-performance applications and professional service, XLS Metals is highly regarded in the industry, and its metallurgical grade silicon carbide has earned the trust and preference of users.
