Lindberg/MPH Ships Electrically Heated Pit Furnace to a Manufacturer of Engineered Components

Lindberg/MPH announced the shipment of an electrically heated, steam atmosphere, pit furnace with a steam generator for steam treating tools steels. Steam treating produces an oxide film on the surface of the part which improves wear and corrosion resistance, and provides a uniform blue-black finish

The pit furnace has a maximum temperature rating of 1250°F and work chamber dimensions of 22" diameter x 36" depth. The maximum gross workload is 1,200 lbs. Vacuum formed ceramic fiber modules with low heat storage provide fast heat up rates. The pit furnace also features a thermocartridge recirculating fan and solid wall baffle for uniform atmosphere and heat distribution.

“This new Lindberg design features a maintenance friendly fan and motor assembly which provides our customer with reliable and easy maintenance.”- Jason Dobberstein, Application Engineering Manager

Unique features of this Lindberg/MPH steam atmosphere pit furnace include:

  • Vacuum formed ceramic fiber modules with low heat storage for fast heat up rates

  • Atmosphere tight retort

  • Heater coils designed with low surface watt density for extended service life

  • Thermocartridge fan for increased heat and atmosphere recirculation

  • Steam piping control

  • Supplied optional steam generator
