Lindberg/MPH Ships Pit Furnace to a Leading Manufacturer of Mechanical Components
Riverside, MI – Lindberg/MPH announced the shipment of a pit furnace to a leading manufacturer of mechanical components. This industrial pit furnace performs a steam treating process on tool steels. Steam treating produces an oxide film on the surface of the part which improves wear resistance, improves corrosion resistance, and provides a uniform blue-black finish.
The heat treating furnace has a maximum temperature rating of 1250ºF. The work chamber is 39" in diameter with a depth of 36” and a total load capacity of 3,700 lbs. Vacuum formed ceramic fiber modules were utilized which have low heat storage and allow for fast heat up rates. The pit furnace utilizes a high limit controller to protect from over temperature conditions and an actuator for atmosphere flow control.
This furnace utilizes ni-chrome heating elements on the interior of an alloy retort to efficiently heat treat parts in a steam atmosphere. A thermocartridge recirculating fan and solid wall baffle provide uniform atmosphere and heat distribution. This new Lindberg/MPH design features a maintenance friendly fan and motor assembly which allows for reliable and easy maintenance when needed, compared to the old Leeds and Northrup furnace design.
“At Lindberg/MPH we work with our customers to provide them with the most effective and efficient equipment solution for their process. This pit furnace offers the customer features that provide ease of maintenance for their staff.” Jason Dobberstein, Inside Sales Manager
