ABSTRACT:
The assembly is designed for transferring molten metal from a molten metal reservoir to a mold for casting molten metal. The assembly comprises a casting nozzle having an electrically conductive top wall and bottom wall and two side walls joined to the top wall and the bottom wall to form a passage therebetween for flowing molten metal from the reservoir to the mold, the top wall having a first outside surface and the bottom wall having a second outside surface. An inductive heater is positioned on at least one of the first surface and the second surface, the inductive heater positioned to heat the top wall and bottom wall. A layer of insulation is provided between the inductive heater and the first and second surfaces. A magnetic shield is provided to partially surround the inductive heater, the shield positioned to direct magnetic flux into the nozzle. A metal support is provided for supporting the top wall and the bottom wall, a layer of insulation provided between the metal support and the top wall and the bottom wall to minimize heating of the metal support and distortion of the top wall and the bottom wall. Further, the metal support is electrically insulated from the inductive heater to minimize heating of the metal support, and the magnetic shield is positioned to substantially avoid magnetic flux entering the metal support.
