Conveyor belt furnaces move in-process workpieces continuously through annealing, brazing, enameling, glass sealing, and hardening stages without requiring human interruption or disrupting heat exposure. With this one piece of equipment, you can streamline your production process to make it faster, smoother, and safer. Belt Furnace. Gas or electrically heated units can be paired with atmosphere generators for controlled atmosphere processing, "Flat-surface" or "broken-surface" belts provide a moving hearth that transports work through the furnace.
