Abstract
This paper presents the results of modeling the ohmic heating of the electrode in an electroslag remelting system using the ANSYS software package. A description of the electroslag remelting installation designed for remelting metals to remove radionuclides is provided. A modeling method is proposed that involves an interdisciplinary simulation using the Electric and Transient Thermal modules of ANSYS. The results demonstrate that this approach enables the calculation of energy release and the corresponding temperature distribution within the electrode. These findings can be used for selecting electrodes of various geometries and materials, as well as for optimizing the operating modes of the electroslag remelting system
