Refractory Challenges in the Transition to DRI-EAF Steelmaking

The shift from blast furnace-basic oxygen furnace to electric arc furnace (EAF) steelmaking using direct reduced iron (DRI), which is particularly happening in Europe, imposes significant challenges on refractory linings. The presentation will compare refractory requirements for scrap- and DRI-based EAFs, highlighting the need for advanced materials and technologies. Key topics include refractory selection, wear monitoring, and maintenance strategies to optimize EAF performance and lifetime in the face of evolving process conditions.
