ABSTRACT
The computer modeling of coupled electromagnetic, thermal and hydrodynamic processes at the induction heating and melting of metals with the use of magnetic flux concentrator is carried out. The non-uniform current density distributions in solid windings of the inductor and the concen-trator are taken into account within the wide frequency range (1—150 kHz). It is shown that the current frequency of inductor should not be less than 20—25 kHz in order to provide high efficiency for heating of metals with high conductivity.
KEYWORDS
