摘要： Disclosed is an induction furnace with improved circulation of the molten metal. The increased circulation and is achieved by positioning the greatest magnetic field strength in a location above one or more of the channel vertical legs. This arrangement is achieved by (a) using an angled core to position the field over the upper channel opening or (b) by positioning the upper channel leg opening by lowering the channel opening to within the magnetic core window.

摘要： Methods and apparatus for moving a molten metal are provided in which the electromagnetic inductor includes at least two pairs of electromagnetic pole pairs and in which a first magnetic field component is generated between one pole in a first electromagnetic pole pair and a second pole in a different electromagnetic pole pair, and in which a second magnetic field component is generated between the two poles in one or more electromagnetic pole pairs, the second magnetic field component thereby generating one or more eddy currents in the molten metal. Those eddy currents are generally parallel to the surface of the molten metal and so have greater magnitude and extent that eddy currents perpendicular to the surface. Such eddy currents provide useful additional movement to the molten metal, for instance for stirring purposes, particularly when the depth of molten metal is small.

摘要： 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.
