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 for the entire production process. As the core component of 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, spring steel, and carbon steel.
