Abstract

Numerical computations of electromagnetic, hydrodynamic and temperature fields are performed for 3D models of the ladle furnace with an EM stirrer, which is a characteristic example of the metallurgical magnetohydrodynamic device with combined power supply. Alternating current supplied by a side non-symmetrical inductor, being the source of a travelling magnetic field, is a driver of melt EM convection. Conductive single- or three-phase AC supplied through electrodes non-submerged into the melt is a driver of melt electro-vortex convection. Thermal field is obtained along with melt circulation by applying a 3D transient LES model of turbulence. Melt overheating is analyzed taking into account the combination of EMC and EVC.
