Abstract Scope |
A drastic reduction of CO2 emissions in steelmaking requires new or adapted processing routes for primary and secondary raw materials. The paper overviews current research attempts and challenges related to green steel production. As one pillar, the use of hydrogen, whether in the production of direct reduced iron (DRI) from fine-grained iron ores with fluidized bed reactor technologies as input material for crude steel production in electric arc furnaces and converter or hydrogen plasma smelting reduction of iron ores to produce crude steel as an emerging breakthrough technology. As a second pillar, the increased scrap rate in terms of circularity. The resulting higher levels o trace elements are hardly removable from the liquid steel and can negatively influence material properties and reactions in the steel-slag-refractory system. The different production routes and their technology readiness levels are discussed and compared, indicating the potential consequences of further processing and usage of by-products. |
