Abstract
A coreless induction furnace comprising a crucible for holding a quantity of metal to be heated by the furnace. The crucible has an open top, side walls and a closed bottom. An induction coil is operatively associated with the crucible for generating a time-varying magnetic induction field. Coupling structure extending above the top of the crucible is provided to couple at least a portion of the induction field to the center portion of the top surface of the metal to be heated.
