A manufacturer for the energy industry has recently announced the installment of a roller hearth furnace system. The heat treat system is comprised of two (2) box furnaces with quench tanks, a dual directional load transfer car, four (4) companion draw batch ovens, and two (2) stationary load/unload tables.
The system from Lindberg/MPH has a maximum operating temperature of 1850°F for the box furnaces, which are designed for nitrogen-based atmosphere applications. The load space dimensions of the box furnaces are 48” W x 96” D x 36” H, with larger internal chambers to provide clearance for baskets or fixtures. A snake chain pusher assembly with a dual-directional pacecar is used by each furnace to transfer the loads from the chamber to the pneumatically operating quench elevator deck.
The glycol quench tanks are designed for quick and uniform quenching, featuring an immersion oil heater and an externally mounted air-to-quench media heat exchanger. The tanks’ agitation systems include four agitators with draft tubes. The gross load capacity of the car is 10,000 lbs., and it travels linearly in front of the equipment on two embedded floor rails.
