Abstract
Electrodynamic processes occurring in molten metal on the horizontal surface of metal product in the inductor magnetic field were studied. Conditions of intensification of liquid metal flows at local treatment of metal surfaces are determined. Formulas for calculation of induction system are given.
Keywords: induction heating, metal treatment, intensified liquid metal flows, electrodynamic processes, calculations
