For the first time a three-dimensional mathematical model was developed and a numerical study of electromagnetic, hydrodynamic and thermal processes in reverberatory furnaces with electromagnetic stirring of aluminum melt using a universal inductor, which alternately creates traveling and pulsating magnetic fields. The basic laws of electromagnetic influence of traveling and pulsating magnetic fields on liquid metal, as well as the combined action of these fields are determined, the parameters of liquid metal motion under the action of electromagnetic forces are established and the thermal state parameters of metal melt for different electromagnetic stirring modes are determined. The power supply system of the universal electromagnetic liquid metal stirrers with alternating force of pulsating and traveling magnetic fields is proposed and investigated. The power supply system of the universal electromagnetic liquid metal mixer with alternating force action of pulsating and traveling magnetic fields is proposed and investigated. It includes two symmetric-compensating devices, which allows to compensate the reactive power and to balance the currents of the mains in both modes of operation of the stirrer. A prototype of a universal electromagnetic stirrer for aluminum was developed and manufactured. The experimental studies carried out on it confirmed the high efficiency of electromagnetic stirrer of the melt with alternating action of pulsating and traveling magnetic fields. An electromagnetic stirrer of liquid metal with a pulsating magnetic field has been developed for a 5-tonne reverberatory furnace used for the production of aluminum alloys from secondary aluminum, which is planned to be introduced into industrial production. The use of these developments in industry will significantly improve the quality of metal melts, in partic Product Description popup.authors Bondar Oleksii I. Glukhen'ky Oleksandr I.
