Abstract
A model of a three-phase electric furnace is considered, for which the distribution of temperature and electric field over the volume is calculated. Areas of the furnace are shown, in which extreme values of current density and temperature occur. The simulation results are compared with the real data of the 12 MVA furnace operation in factory conditions, and the features of the furnace operation in various modes are discussed. 6 Ref., 7 Fig.
Keywords: simulation, furnace, electrical mode, temperature distribution, current density
