Abstract
A method of removing non-metallic inclusions from a molten metal comprises the step of simultaneously applying both a horizontal rotation of the molten metal and heating of the molten metal by induction heating. After the simultaneous application of rotational force and heat, the induction heating may be stopped while the horizontal flow of the molten metal is maintained, so as to promote the separation of the particles of the inclusions. The method is carried out by using an apparatus which has a vessel which contains the molten metal, a rotary magnetic field generating device surrounding the vessel, and an induction heating device also surrounding the vessel. Each of the rotary magnetic field generating device and the induction heating device may be divided into a plurality of circumferential segments and arranged such that the segments of both devices are alternately disposed around the vessel.
