Abstract : To improve the quality of the electromagnetic stirring of liquid metal periodically alternate a force to the metal of the traveling and the pulsating magnetic fields has been proposed. Two constructions of the electromagnetic stirrer of the metal in the form of two-limb and three-limb inductors are considered, that allow implementing of such a method of stirring due to the periodic alternation of their multiphase and single-phase power supply. With reference to reverberato-ry furnace for aluminum based on the 3D computer modeling electromagnetic and hydrodynamic processes in the sys-tem -inductor – a bath of liquid metal- have been investigated. It is shown, that in the case of multiphase power supply both inductors produce in the furnace bath single-circuit vortical flow of metal, but in the case of single-phase power supply – dual-circuit vortical flow. Thus stagnant zones of metal that presents in one mode are effectively stirred in another. The durations of transient hydrodynamic processes have been identified. A comparative assessment of the effectiveness of such stirrers for different modes of operation has been executed.
