Lindberg/MPH shipped an electrically heated rod overbend atmosphere box furnace to a company in the aerospace industry. The box furnace will perform a heat treatment on parts within the work chamber under a reducing atmosphere generated from a nitrogen-methanol panel. It has a maximum temperature rating of 2000°F and work-chamber dimensions of 24 inches wide x 36 inches deep x 24 inches high.
A recirculating fan distributes atmosphere and heat evenly within the work chamber, and temperature uniformity is +/-25° F at 2000°F. The rod overbend box furnace also utilizes an integrated carbon control circuit for neutral hardening. The chamber is heated with a radiant heating system that uses heavy-gauge-alloy rod overbend heating elements positioned on the chamber side walls and floor. Multiple thermocouple jacks are located on the outside of the furnace shell to allow for easy connection to thermocouples at various locations.
