Abstract Scope

Decarbonization of the iron & steel industry has recently been the focus of many research and technological development tasks. Most of the developments are targeting the replacement of the highly CO2 emissive blast furnace (BF), which has been the primary smelting furnace in the ironmaking step of steel production. However, replacement of the BF has been a challenging task because of BF’s many established capabilities over the years, especially its flexibility in using low-grade iron feed. In this regard, Metso (metso.com) has been developing an advanced furnace technology, Metso’s Outotec direct reduced iron (DRI) smelting furnace. The recently developed 6-in-line electric furnace for DRI smelting can be used for smelting of DRI with a BF grade iron ore. Compared to the electric arc furnace (EAF), the DRI smelting furnace can handle larger slag volumes that normally emanate from the high gangue in the BF-grade DRI.
