The electrovortex movement of liquid metal in a direct current arc furnace with a bottom electrode under its own electromagnetic field has been investigated. The physical and mathematical formulations of the processes are given. The algorithm of a solution was developed and the method and software packages for modelling the processes were chosen. The results of electromagnetic and magnetohydrodynamic field analyses in the industrial furnace are given. The verification of results has been done by comparing them with general electrovortex movement theory, experimental data and results of similar software packages.
