Lindberg/MPH cyclone pit furnace heat-treats aircraft components

Lindberg/MPH has shipped an electrically heated cyclone pit furnace to a steel heat treater for heat-treating aircraft components.

The maximum temperature rating for this electric pit furnace is 1,250 degrees F. The work chamber is constructed with an alloy liner backed with 7 in. of block insulation. This design met the required +/-10-degrees-F temperature uniformity throughout the qualified work zone.

The top-load furnace features a thermocartridge recirculating fan and solid wall baffle for uniform heat distribution. The furnace fan uses a centrifugal blower-type alloy blade and a 5-HP motor with belt and pulley drive system. The steel outer shell is constructed from heavy-gauge steel plate reinforced with structural steel members.
