SYSTEM FOR INSULATING AN INDUCTION VACUUM FURNACE AND METHOD OF MAKING SAME

摘要

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.
