Smelter Technology for Transforming Integrated Steelmaking Toward Net-Zero Carbon (Room 308)

Today, the iron and steel industry is the second-largest global industrial CO2 emitter. Direct reduction using low-carbon hydrogen is the most promising solution to achieve the industry target of climate neutrality. However, the common solution to use the electric arc furnace for processing direct reduced iron (DRI) is only beneficial for high-grade ores. Most of the iron ores globally available is of lower grade and new solutions for processing of such lower-grade DRI is required. A two-step process combining a smelter with a basic oxygen furnace converter can handle such lower-grade ores and is predestined for implementation in existing integrated plants.
