ABSTRACT:
An improved heat treatment furnace and method of constructing the same is enclosed wherein the duct work of the furnace includes directional vanes and adjustable plenum vents and chamber dampers to yield a substantially uniform air flow pattern within the heat treatment chamber. The plenum vents and chamber dampers are provided with remotely operable actuating means which permit rapid adjustment of the vents and dampers from the exterior of the furnace during the heat treatment process and/or furnace certification. The furnace additionally incorporates a novel ribbon heating element/fiber insulation assembly and construction method which substantially reduces furnace operating costs and insures that only conventional heat transfer (as opposed to radiant) occurs within the heat treatment chamber of the furnace.
