Lindberg/MPH Ships Atmosphere Box Furnace to Aerospace Company

Lindberg/MPH announced the shipment of an electrically heated rod overbend atmosphere box furnace to 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.

The atmosphere box furnace has a maximum temperature rating of 2000°F and work chamber dimensions of 24" wide x 36" deep x 24ʺ 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 furnace shell is constructed from welded steel plate and the chamber is heated with a radiant heating system that uses heavy gauge alloy rod over-bend heating elements positioned on the chamber side walls and floor. The metal to metal door seal eliminates air intrusion into the work chamber and multiple thermocouple jacks are located on the outside of the furnace shell to allow for easy connection to thermocouples at various locations.

“This box furnace is an ideal solution for neutral hardening as it includes a nitrogen methanol control panel, paperless chart recorder, recirculating fan, and curtain burner for safe operation.” ~Jason Dobberstein, Application Engineering Manager

Unique features of this Lindberg/MPH box furnace include:

  • Nitrogen methanol panel

  • Recirculating fan

  • Variable frequency drive

  • Exterior thermocouple jacks

  • Carbon probe

  • Metal to metal door seal

  • Door limit switch

  • Door curtain burner
