Apparatus (10) for inductively melting a quantity of metal without a container includes a first induction coil (12) having a plurality of turns (14) defining a volume for receiving a quantity of metal (18), the first induction coil being adapted to exert a force on the metal, a second induction coil (34) having a plurality of turns (36) at substantially right angles to the turns of the first induction coil, the second induction coil being disposed within said volume coaxial with the first induction coil. Both the first and second induction coils have connecters thereon for connecting the coils to at least one power supply for energising the first and second induction coils. A support (20) is provided for supporting the metal from below and has an opening through it. The support includes a raised segmented rim (24) around substantially its entire periphery. The support is maintained at a preselected temperature. In an alternate embodiment, structure (38 or 44,46,48,50,52) is also provided for imparting rotational motion to the support. <IMAGE> |
