Abstract
An apparatus for manufacturing solidified metallic forms from levitated molten metal including a levitation conduit having an interior surface for accommodating the metal to be levitated, and a device for introducing the metal to the levitation conduit. Induction coils induce a moving magnetic field in the levitation conduit to levitate the metal upwardly through the conduit, and to maintain the outer surface of the levitated metal while molten out of pressured contact with the interior surface of the levitation conduit. The molten metal output is provided to a chamber in which a device re-forms the molten metal output and solidifies it.
