Abstract:
A tilting rotary furnace with a door assembly that seals against a furnace vessel. The seal between the door and the furnace vessel allows for regulation of the internal environment of the furnace and control over thermitting of the aluminum. As a result, aluminum recovery may be carried out without the use of salt. A portion of the door may rotate with the furnace vessel and a portion of the door may remain rotationally stationary with respect to the furnace vessel and the rotating portion of the door.
