Abstract: A system and method for removing impurities in an induction furnace cooling system is disclosed. An induction furnace for heating a workpiece includes a chamber, an induction coil positioned in the chamber to provide for heating of the workpiece when a current is provided to the induction coil, and a cooling system fluidly coupled to an interior volume of the chamber, the cooling system including a heat exchanger, a blower fluidly coupled to the heat exchanger and configured to cause a gas to flow through the heat exchanger, and a filter assembly comprising a filtering device, the filter assembly fluidly coupled to the blower and configured to remove impurities from the gas flowing through the cooling system.

Abstract: A system and method for insulating an induction vacuum furnace is disclosed. An induction furnace for heating a workpiece includes a chamber, an insulation cylinder positioned within the chamber, and an induction coil positioned to surround at least a portion of the insulation cylinder. A susceptor is positioned within the insulation cylinder and inductively heated by the induction coil when a current is provided to the induction coil. An insulating jacket assembly including one of a carbide material and a refractory metal is positioned in a space between the insulating cylinder and the susceptor.
