Aerospace Industry Acquires Box Furnace for Heat Treating Parts

An aerospace company has purchased a rod overbend box furnace to heat treat parts under an inert atmosphere. The heat treating furnace has a maximum temperature rating of 2,000°F and a load capacity of 6,000 lbs.

The box furnace, which was manufactured and shipped by Michigan-based Lindberg/MPH, has an automated load transfer table and is designed to heat treat parts in a nitrogen atmosphere. A nitrogen gas flow meter controls the atmospheric conditions. 

The box furnace includes an automated load transfer table. Under the table, five (5) fans with a variable-frequency drive provide accelerated cooling. The load table utilizes a pusher/puller mechanism to move parts trays in and out of the furnace.

The furnace’s radiant heating system uses heavy-gauge alloy rod over-bend heating elements mounted along the side walls and the floor. Two (2) Watlow F4T controllers control and record the furnace temperature, which allows for seven (7) zones of heating. The box furnace also meets Class 3 temperature uniformity of ±15°F at 1,000°F – 1,800°F.

Mueller Brass Co. Soon to Heat Treat with New Sintering Furnace

HTD Size-PR Logo

A batch sintering furnace will be installed at Mueller Brass Co., a major supplier of brass rod and forgings in the United States. The 60" wide x 90" deep x 30" tall atmosphere box sintering furnace includes an accelerated gas cooling system to improve floor-to-floor cycle time and meet their demanding production needs.

This Gasbarre Thermal Processing Systems box furnace is designed with a maximum operating temperature of 1650°F, a capacity of 14,000 lbs., and utilizes a nitrogen atmosphere. The system incorporates an Allen-Bradley PLC with SSi 9130 control and 12.1" HMI display. Additionally, the indirect fired gas heating system incorporates parallel positioning control for efficiency and process flexibility, and an integrated oxygen analyzer gives Muller Brass Co. the proper furnace environment prior to heating.
