Abstract

This article focuses on a patented method for inducing and controlling azimuthal rotation of the melt in a direct current (DC) electric arc furnace (EAF) by installing power supply electrodes at an incline, eliminating the need for an external axial magnetic field. The inclined electrodes create a Lorentz force with a significant azimuthal component, driving melt rotation without additional energy consumption for magnetic field generation. The method was validated through observations and large eddy simulation (LES) numerical studies on both a laboratory-scale setup using a GaInSn alloy and an industrial-scale DC EAF with molten steel. Control of melt flow and rotation can be achieved by adjusting the number and inclination angle of electrodes, as well as the sequence of power supply activation. This approach offers an energy-efficient alternative for melt flow management in DC EAFs, supported by experimental and computational evidence.
