| Abstract Scope |
Electric Arc Furnaces (EAFs) play a crucial role in steelmaking due to low-emissions and flexibility of EAF operations. However, EAF include complex processes that require further understanding for process optimization. This investigation focuses on refining stage of EAF, which involves reactions driven by oxygen injected by coherent jets. Namely, a CFD model implemented for EAF refining is validated against data provided by EVRAZ NA. Validation demonstrates close alignment of simulation to real process, where the difference is 1.78–3.57%. Validated CFD model is applied to investigate impact of O2 injection on decarburization. Minimal impact occurs when O2 rates are varied among burners while keeping total injection the same. Furthermore, increasing total O2 rate 10% improved decarburization in 1.37%, while reducing total O2 rate 17% deteriorated decarburization in 4.2%. The validation and application results in this study demonstrate the CFD model capabilities to provide guidance for refining optimization in real EAFs. |
