Modelling results of electromagnetic and hydrodynamic processes in system “inductor - liquid metal” for universal stirrer of liquid metal with linear inductor, which due to the sequential action of single phase and multiphase power supply can create pulsed and traveling magnetic fields respectively, are presented. Influence of basic parameters of such stirrer, that are gap between inductor and liquid metal, number of cores (poles) and inductor pole division, on the efficiency of electromagnetic stirring of liquid metal in melting furnace bath have been determined. There is dual circuit flow of liquid metal in the case of single phase power supply. And depending on pole division and air gap a single circuit flow like also the dual circuit flow can be created in the case of multiphase power supply. Recommendations on structural implementation of universal stirrer, which sequentially creates single circuit and double circuit flows, that allow effectively stir liquid metal in all volume of furnace bath, have been provided. References 5, figures 6.
Key words: electromagnetic stirring, liquid metal, inductor, pulsed and traveling magnetic fields, numerical modelling, structural parameters.
