Pit Furnace for Heat Treating Aircraft Components

Lindberg/MPH announced the shipment of a cyclone pit furnace to a supplier of the aerospace industry. The pit furnace performs a heat treating process on aircraft components. The cyclone design has historically provided optimum heat distribution and exceptional temperature uniformity which makes it ideal for applications such as tempering, normalizing, solution treatment of aluminum and annealing.

This heat treating pit furnace has a maximum temperature rating of 1250º F. The work chamber is 16" in diameter with a depth of 20”. This cyclone pit furnace is a direct replacement of an existing piece of Lindberg/MPH equipment the customer already had in place. Lindberg/MPH provided a centralized control system with a programmable logic controller to control this equipment and six other furnaces. The cyclone pit furnace design utilizes a heater plug assembly that is easily lifted out and replaced externally without having to pull elements out through the furnace walls for easy maintenance.

 “This customer was looking to improve their efficiency of operating their furnace line. By providing a control system that allowed them to monitor and control multiple units, it greatly simplified the customer’s process and fulfills their data acquisition needs.” Jason Dobberstein, Inside Sales Manager

 Unique features of this cyclone pit furnace include:

  • Alloy liner protects work chamber from high velocity flow and prevents damage while loading/unloading

  • Easily replaceable heater plug assembly

  • Recirculating fan with variable frequency drive

  • Workload support

  • Lid limit switch
