April 23, 2018 – Lindberg/MPH announced the shipment of three (3) natural gas fired box furnaces to a parts manufacturer for the oil and gas industry. The box furnaces will be used to develop process control requirements for heat-treating and stress relieving of underground mining/drill heads. These types of mining/drill heads only last a few hours to a few days depending on the composition of the ground and the goal is to double the life of the tooling through research which would revolutionize industry standards.
The maximum operating temperature rating for the stress relieving box furnaces is 2050°F and work chamber dimensions are 36" wide x 20" deep x 24" high. The box furnaces were designed to meet a temperature uniformity of +/-15°F at 1700°F and 2050°F per the requirements of AMS 2750E, Class 3 furnaces and Instrumentation D.
The stress relieving box furnaces utilize automatic chamber pressure controls and space saving rear mounted burners. To accommodate the tight floor spacing requirement of the customer, specialized burner passages were customer designed to provide convection heating while eliminating flame impingement on the part.
“The chamber pressure control for these box furnaces, which is a positive internal pressure that is maintained throughout the entire range of the furnace input, increases temperature uniformity and lowers operating costs for the customer.” -Kenneth Zielke, Sales Engineer
Unique features of these Lindberg/MPH heat treating box furnaces include:
- AMS 2750E Class 3 furnace, Instrumentation Type D
- AMS compliant temperature controller with graphic video recorder
- Temperature uniformity of +/-15°F at 1700°F and 2050°F
- 300 pound load capacity
- 750,000 BTU/hr input
- VFD combustion blower and chamber pressure control
