Abstract Scope |
The steel industry is under increasing pressure to reduce CO2 emissions across all stages of production, with ironmaking and steelmaking identified as the primary contributors. To meet societal demands and promote sustainable manufacturing, greater use of ferrous scrap in both electric arc furnace (EAF) and basic oxygen furnace (BOF) processes is being actively encouraged. However, the presence of tramp elements, in particular Cu and Sn, in molten steel derived from scrap presents a significant challenge for both steelmakers and metallurgists. In this presentation, the potential for removing Cu and Sn via evaporation is explored. The effects of key variables such as temperature, steel chemistry, and pressure on the evaporation rate are discussed, based on the present authors' recent investigations involving thermodynamic and kinetic analysis, high-temperature gas–liquid experiments, and degassing process simulations. Several critical insights were identified, offering promising directions for the future development of practical tramp element removal technologies. |
