The Ladle Refining Furnace is designed to refine molten steel from primary melting furnaces (electric arc furnace, induction furnace, converter, etc.), while also adjusting molten steel temperature and serving as a buffer in the production process. Considered essential for optimal production lines (primary melting furnace + LF + CCM), it is widely used for refining various steel grades including ball bearing steel, alloy structural steel, tool steel, and spring steel.
