Lindberg/MPH Car Bottom Industrial Furnace

Because of the consistent reliability and performance of their existing 25+ year old Lindberg car bottom furnaces, our customer was compelled to select Lindberg for their new plant expansion for their heat treating needs.

Lindberg/MPH announced the shipment of two (2) car bottom industrial furnaces used for curing aircraft engine hardware consisting of ceramic-metallic composite shapes. Both furnaces heat a maximum 5,000 lbs load. One unit heats from 200°F to a maximum temperature of 2100°F. The second unit heats to 2800°F. The electrically powered furnaces utilize two heating systems; an auxiliary preheater and an air recirculation system to achieve uniform temperature at low temperatures, as well as radiant heating elements for uniform high temperature operation. The customer required temperature uniformity of ± 20°F for an optimal cure.

The workloads are manually placed on a self-driven car and driven into the industrial furnaces. The car bottom furnaces also feature fast cooling technology. The re-circulating blower pulls air from the pre-heater, re-circulates it through the furnace and then back through the pre-heater again. A butterfly valve allows the pre-heater air piping to be by-passed and cool ambient room air to be pushed into the furnace chamber for fast cooling. Roof mounted exhaust flues with air cylinder operated coves open during the low temp curing process to vent fumes from the product as well as during the fast cooling process.

“Because of the consistent reliability and performance of their existing 25+ year old Lindberg car bottom furnaces, our customer was compelled to select Lindberg for their new plant expansion for their heat treating needs.” Tim Josephs-Heat Treat Sales Manager
Unique features of these industrial furnaces include:

  • Furnace heating element input is 300 kW (2100°F Unit), 478 kW (2800°F Unit)
  • Moldatherm® embedded heating elements in the 2100°F furnace.
  • Globar heating elements for the Pre Heater and 2800°F furnace including tapped variable reactance transformers for 2800°F furnace.
  • Honeywell HC900 PLC with 15" Honeywell Model 900CS15 HMI for temperature control, data logging and process control
  • Furnace heat chamber is controlled by three (3) independent zones in the 2100°F furnace and two (2) independent zones in the 2800°F furnace
  • Provisions to connect up to twelve (12) additional profile thermocouples are available in a box located on the side of the control cabinets
  • Air powered seals thermally seal the car bottom and door to the main furnace chamber.
