Low-Emission Hot Metal Production From DRI/HBI

The addition of hot briquetted iron (HBI) in blast furnaces (BF) is an established practice to increase productivity and reduce emissions from hot metal (HM) production. Electric smelting furnace technology is emerging as an alternative process for producing HM from direct reduced iron (DRI) that is competitive with BF ironmaking. The authors use first-principles process models and reference data to compare the economic, supply chain, process and product implications of these methods of using DRI to produce HM. Practical scenarios for adoption as pathways to transform existing integrated steelmaking operations will be discussed.
