METHOD FOR CONTROL OF THE VORTEX FLOW INTENSITY BY CHANGING THE BOTTOM POSITION IN A DC ARC FURNACE WITH A BOTTOM ELECTRODE

This paper describes methods and approaches for numerical simulation of liquid metal flows in a direct current (DC) arc furnace with a bottom electrode. The model for numerical simulation takes into account an actual bottomelectrode arc furnace and is based on magnetohydrodynamic equations. The distributions of the Lorentz force, temperature, and the vortex flow velocity are presented. The method to control and reduce the vortex flow intensity in a liquid metal volume by changing the furnace bottom position is worked up. The results of the numerical simulation show a possibility to reduce a negative influence of the vortex flow of a liquid metal up to 50%.
