Abstract
A vacuum heat treating furnace for the heat treatment of metal parts includes a pressure vessel and a hot zone enclosure that defines a hot zone therein. A heating element array inside the hot zone enclosure includes a first heating element, a second heating element, and a center heating element. The first and second heating elements are suspended on opposing sides of the hot zone enclosure. The center heating element is suspended vertically from the hot zone enclosure between the first and second heating elements. The center heating element is adapted to be connected to the first and second heating elements to form a continuous circuit therewith. The center heating element may be connected to the first and second heating elements with removable/reusable fasteners to provide for reconfiguration of the hot zone to accommodate different size workloads.
