    摘要： The invention relates to an induction crucible furnace and to a magnetic return element for an induction crucible furnace. The induction crucible furnace has a corresponding coil and a plurality of magnetic return elements, which are designed in the form of individual units arranged on the outer lateral surface of the coil with peripheral spacing. In order to guide the magnetic flux produced by the coil, the magnetic return elements each have an assembly consisting of a plurality of elongate individual elements of magnetically permeable material that are electrically insulated from each other and extend parallel to the furnace axis. Said individual elements consist at least partially of bars, which are electrically insulated from each other and the longitudinal axes of which extend parallel to the furnace axis. In this way, both eddy currents that hit the assembly from the radial direction and eddy currents that hit the assembly with a transverse component are minimized.

    摘要： Apparatus and method are provided for damping the induced fluid flow, particularly in the region of the base plate, in an electrically conductive material that is heated and melted in a cold crucible induction furnace. Damping is accomplished by establishing a dc magnetic field such that flow of the electrically conductive liquid metal in that dc magnetic field would induce eddy currents in the liquid metal which would generate forces that tend to oppose the flow. The dc magnetic field may be established by dc current flow in the ac induction coil that induces current in the material, dc current flow in a separate dc coil, or coils, constructed to prevent excessive induced losses, by discrete magnets, or a combination of any of the three prior methods. The dc magnetic field may also be established by dc current flow in one or more dc coils disposed around a magnetic pole piece located below the base of the furnace. One end of the magnetic pole piece is located adjacent to the bottom of the crucible base, so that the pole piece concentrates the dc field into the lower portion of the molten electrically conductive material.

    摘要： Apparatus and methods of operation are provided for a cold-crucible-induction melter for vitrifying waste wherein a single induction power supply may be used to effect a selected thermal distribution by independently energizing at least two inductors. Also, a bottom drain assembly may be heated by an inductor and may include an electrically resistive heater. The bottom drain assembly may be cooled to solidify molten material passing therethrough to prevent discharge of molten material therefrom. Configurations are provided wherein the induction flux skin depth substantially corresponds with the central longitudinal axis of the crucible. Further, the drain tube may be positioned within the induction flux skin depth in relation to material within the crucible or may be substantially aligned with a direction of flow of molten material within the crucible. An improved head design including four shells forming thermal radiation shields and at least two gas-cooled plenums is also disclosed.
