Compact coil assembly for a vacuum arc remelting system

A vacuum arc remelting system for forming an ingot from an electrode, the system comprising:

• a crucible assembly configured to accommodate the electrode and the ingot;
• a coil assembly arranged about the crucible assembly, the coil assembly comprising a magnetic core and a plurality of coil pairs wrapped around the core, wherein the coil assembly is operable to generate a magnetic field from the coil based on an electric current received by each coil of the plurality of coil pairs;
• and
• a lift mechanism operatively engaged with the coil assembly, the lift mechanism being operable to move the coil assembly along a longitudinal axis of the crucible assembly such that the magnetic field from the coil is localized to an arc region during remelting.

A vacuum arc remelting system for forming an ingot from an electrode, the system comprising:

• a crucible assembly configured to accommodate the electrode and the ingot;
• and
• an electromagnetic energy source arranged about the crucible assembly, wherein the electromagnetic energy source and the crucible assembly are configured to move relative to one another along a longitudinal axis of the crucible assembly,
• wherein a magnetic field generated by the electromagnetic energy source is localized to an arc region during remelting.
