This paper presents a comprehensive model of an industrial electric arc furnace (EAF) based on rigorous first-principles submodels of heat exchange and industrial experience. The model is designed for process simulation, optimization, and control applications, accounting for energy demands met by six sources, including electric arcs and oxy-fuel burners. Various mechanisms of heat exchange are precisely represented, utilizing techniques such as the DC circuit analogy for radiative heat computation and experimental data for modeling splashing effects. The melting rates and efficiency of oxygen lancing were determined through least squares fitting to real process data from an Ultra-High-Power EAF. In comparison with existing EAF models, this model represents the dynamic behavior of the melting process more realistically, allowing for the computation and discussion of time-dependent energy efficiency curves for various contributions and the overall process.
