High Temperature Resistant Refractory Essential Auxiliary Material Silicon Carbide for Steelmaking. is an essential auxiliary material for steelmaking, continuous casting, refractory materials and furnace linings. It features high hardness, high refractoriness and melting point, excellent thermal and electrical conductivity. as well as superior thermal shock resistance, slag & iron erosion resistance, oxidation resistance, wear resistance and corrosion resistance. Silicon carbide can be added to tundish covering flux and ladle slag to improve heat preservation, anti-oxidation performance and inclusion absorption capacity. When applied to long nozzles, monolithic stoppers and submerged entry nozzles, it enhances thermal shock resistance, slag erosion resistance and anti-clogging performance. It is also widely used in blast furnaces, converters, electric furnaces, as well as castables for iron runners and slag runners, boosting wear resistance, slag resistance and service life.
