Radiation modeling in an EAF

A radiation model developed to quantify the radiative energy exchange inside an electric arc furnace (EAF) is studied. The proposed model permits the estimation of the effect of exposed arc length and determines the temperature distribution of different parts of the furnace. The proposed model enables the determination of heat extracted by water-cooled panels and roof. It is observed that the heat loss by conduction through an electrode is about 0.3 percent of the total electric energy for the simulated cases.
