ABSTRACT:
Method of and apparatus for providing agitation of the melt in the induction melting of metals. A medium frequency melting power supply (12) of an induction furnace or crucible (10) acts in conjunction with a modulating circuit incorporating a wave form generator (14) whereby modulation at predetermined amplitude and frequency is applied to the furnace power frequency during at least part of the melt processing cycle to cause agitation of the melt to a predetermined extent independently of the selected overall power input.
