SUMMARY:Green hot metal from a smelter processing low grade DRI
DESCRIPTION:"Today the iron and steel industry is the largest global industrial CO2 emitter, its main emissions coming from iron making via the blast furnace. Direct reduction using low-carbon hydrogen is at the moment the most promising solution to achieve the industry target of climate neutrality. However, the common solution to use EAF for processing of DRI is only beneficial for high grade ores, while most of the iron ores globally available is of lower grade with higher gangue content. New solutions for profitable processing of such lower grade direct reduced iron are required. A two-step process combining a Smelter for green hot metal production with a BOF converter can handle such lower grade ores and might become a prefered solution for an implementation in existing integrated plants. The Smelter is designed to handle wide range of direct reduced materials coming from MIDREX, HyREX or HYFOR plants.
The Smelter allows for efficient separation of slag and metal; after granulation the slag from the Smelter can be used in the cement industry as an latent hydraulic active binder similar to blast furnace slag today, promoting the circularity of ironmaking. The Smelter is designed for continuous operation with a large hot heel and charging and tapping during power on. Annual productivity up to 1,5mta can be achieved with one Smelter, for higher productivity two Smelters will be operated in parallel.
In the paper the principles of the two-step process as well as the main design features of the Smelter will be presented together with an outlook on the implementation and upscaling plan."
