An induction melting system uses a crucible formed from a material that has a high electrical resistivity or high magnetic permeability and one or more inductor coils formed from a wound cable consisting of multiple individually insulated copper conductors to form an induction furnace that, along with its associated power supply, provides a compact design. The system components are air-cooled; no water-cooling is required. The induction melting system is particularly useful for separating metal from scrap, casting molds directly from the induction furnace, and providing a continuous supply of molten metal.

1. An induction furnace for melting a metal charge, comprising:a crucible for holding said metal charge, said crucible formed substantially from a material selected from the group consisting of silicon carbides, high electrical resistivity steels and high permeability steels; at least one induction coil comprising a cable wound of a plurality of conductors isolated one from the other, said at least one induction coil surrounding said crucible; and an electrically and thermally insulating isolation sleeve of low magnetic permeance separating said crucible from said at least one induction coil.
