The Waterbury Farrel Annealing Furnaces are used to anneal brass parts after forming. The annealing furnace is an electrical resistance heating furnace either with a continuous metal mesh conveyor belt or a fabricated long drum with an internal screw type auger, with automatic temperature control system. Parts are deposited directly onto the conveyor or at the opening chute of the drum, where they travel into the multi-zone electric furnace with an option of a nitrogen atmosphere at a specific speed. It also has a cooling zone at the end to cool the parts to a reasonable handling temperature before offloading.
