Abstract
The influence of the frequency of the inductor current exciting a rotating magnetic field (RMF) harmonically varying with time in the melt on the distribution of angular velocity of melt rotation along the symmetry axis of a conical vessel has been studied on a cold model of the liquid core of a continuous steel ingot. Two resonance frequencies are revealed testifying to a complicated oscillatory character of the flow structure in the liquid core. Figs 3, Refs 5.
