Lindberg/MPH, Riverside, MI, announced the shipment of a rod overbend box furnace with an automated load transfer table to the aerospace industry. This furnace will 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. It features a workspace of 36” W x 96” D x 36” H and is designed for 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 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 Watlow F4T controllers control and record the furnace temperature, allowing for seven zones of heating. The box furnace also meets Class 3 temperature uniformity of ±15°F at 1,000°F – 1,800°F.
