After adding silicon carbon powder to molten steel, it will float on the surface and accumulate dust, causing an unfriendly operating environment and incomplete reaction. In order to solve such problems, the ball pressing process has emerged, which compresses powdered materials into spherical shapes and then air dries or dries them to obtain silicon carbon alloy ball. This greatly improves the convenience of feeding. The metallurgical silicon carbon ball sinks to the bottom of the molten steel, reacts thoroughly, and improves the alloy recovery rate.
Reducing costs and increasing efficiency is the demand of enterprises. With the development of the metallurgical industry, silicon carbon sphere can replace traditional silicon iron, silicon carbide, and carburizers at a lower cost. Silicon carbon alloy balls have good deoxidation effect, can also improve the hardness and toughness of steel, and can improve the graphitization performance of cast iron. Its low price reduces steelmaking and casting costs, its good deoxidation effect improves the quality of steel, and its convenient operation improves the working environment for employees. So silicon carbon alloy balls have been widely used.
