| Abstract Scope |
This work presents an integrated FactSage–COMSOL Multiphysics study to characterize heat transfer in fluids, laminar flow, and equilibrium discharge (Plasma) physics to capture temperature evolution, plasma–metal interaction, and convective flow within the molten pool. Concurrently, FactSage thermodynamic calculations were performed over the 900–2000°C range to predict phase formation and speciation of iron oxides, reduced iron, and slag components as a function of temperature and hydrogen environment; hydrogen influence was explored by varying different H₂ flow rates. Results indicate that plasma heating produces highly localized, rapid melting with shorter times to thermal equilibrium compared with conventional EAF scenarios. Thermodynamic predictions show that increasing H₂ availability shifts the equilibrium from iron-oxide phases toward metallic iron and lower slag species, enhancing reduction kinetics and altering slag chemistry at elevated temperatures. Model predictions are consistent with available experimental and plant-scale trends. These findings inform process optimization for energy efficiency in plasma-based steelmaking |
