Abstract
Empirical models that are applied to calculate the specific electrical energy demand of electric arc furnaces in steel industry are compared to a thermodynamic analysis of the melt down process. The influence of various process and plant technologies on the specific electrical energy demand is investigated and compared with the regression coefficients of empirical models from Köhle, and Adams and co-workers. For this purpose, thermodynamic analysis of the energy transfer from various sources to scrap and melt of the EAF process is applied. From the complete energy balance of the EAF process ranges of coefficients are derived relating the electrical energy input with process parameters (i.e. input of scrap, coal, hot metal, slag formers, oxygen). These ranges of coefficients correspond to fitting parameters of linear regression models as proposed by Köhle. As a result, hints for further refinements of the Köhle statistical model of electric energy demand are given.
