| Tower Furnace for Solution Heat Treating of Aluminum Tubing |
The tower furnace design was selected to minimize distortion and provide optimum material handling. The furnace is electrically heated with bayonet heating elements and utilizes a mesh and motor insulation method used in many of our aluminum process furnaces. The furnace is supported by structural members which span the quench pit below.
To move the work in and out of the furnace, SECO/WARWICK designed a rotating carousel that contained two drywell positions and two quench well positions. To load the work into and out of the well positions, a load carriage was supplied to raise the tubing from floor level up to a vertical position adjacent to the furnace. The carriage locks in place after reaching the vertical position, and the tubing is lowered down into one of the drywell chambers at the carousel, then released. The carousel rotates and positions the load directly under the furnace. The furnace hoist lifts the work vertically into the furnace chamber for heat treating. The carousel is then rotated, to position one of the two quenching wells under the furnace.
Following heat treatment, the furnace door opens, and the work is lowered into the water filled pit. The rate at which the work is lowered is controlled by a variable speed hoist. Any distortion that occurs and the resulting metallurgical properties obtained, are directly related to the speed in which the work enters the water. By vertically hanging the load, and controlling the speed in which the work enters the water, distortion can be better controlled so that a wide range of sizes can be processed. The temperature uniformity obtained in the furnace is plus or minus 3 degrees F.
