To provide a suitable system and method of electromagnetic influence on an electroconducting continuum.
Application of amplitude-and frequency-modulated helically traveling (rotating and axially traveling) electromagnetic fields in metallurgical and chemical technologies and foundry can considerably increase the hydraulic efficiency of MHD facilities, intensify the processes of heat and mass transfer in technological plants, significantly increase their productivity, considerably decrease energy consumption for the production of metals, alloys cast articles, and chemical products, and improve their quality. In a method of controlling the crystalline structure of ingots and castings of ferrous and non-ferrous metals, the melt is crystallized in helically travelling magnetic fields excited by m-phase systems of helical alternating currents, wherein the currents are hierarchically frequency-and amplitude-modulated, and the modulation is superimposed on the m-phase systems of currents in the form of pulses with a certain periodically repeated duration in time.
