NUMERICAL SIMULATION OF MELT FLOW CONTROL BY CONTROLLING AVERAGED ELECTROMAGNETIC FORCES GENERATED IN HIGH FREQUENCY MAGNETIC FIELD

摘要

Melt flow is simulated based on a mathematical model of melt convection in a high frequency magnetic field. The model is given briefly. The induction furnace with a complex inductor is proposed. Melt flows for the heating and surface cleaning modes of the proposed furnace are numerically simulated. Results are given and described. A way of melt flow control during melting is described. The suggested technical solution may help to resolve the problem of the oxide scrab presence on the melt surface.
