20.500.12556/DKUM-97395 Simulation-based optimization of coupled material–energy flow at ironmaking-steelmaking interface using One-Ladle Technique The ironmaking-steelmaking interface of the steel manufacturing process involves the hot metal ladle circulation and the energy dissipation which are coupled processes with an interrelated but independent relation. Therefore, the synergistic operation of the material flow and the energy flow at the interface is momentous to the effective production of the ironmaking-steelmaking section. However, there is a lack of solutions to realize the synergy. Here, we presented a coupling simulation model for the material flow and energy flow of the ironmaking-steelmaking interface, based on the mathematical description of their operation behaviors, the operation and technical model of the production equipment and the temperature-decreasing model of the ladle. Further, the coupling simulation model was applied to a concrete ironmakingsteelmaking interface using the One-Ladle Technique. The coupling simulation model proved its performance in providing comprehensive decisionmaking supports and optimized production management strategies by achieving a solution that results in a decline of 10 ℃ in the average temperature drop of the hot metal and a reduction in the cost per tonne of steel by CNY 1.02. metallurgy ironmaking process steelmaking process ironmaking-steelmaking interface coupled material-energy flow discrete event simulation optimization One-ladle technique metalurgija postopek izdelave železa postopek izdelave jekla vmesnik med proizvodnjo železa in jekla sklopljen pretok materiala in energije simulacija diskretnih elementov optimizacija tehnika z eno zajemalko true false true Chair of Production Engineering (CPE), University of Maribor Faculty of Mechanical Engineering Angleški jezik Slovenski jezik https://apem-journal.org/ Content from this work may be used under the terms of the Creative Commons Attribution 4.0 International Licence (CC BY 4.0).
