Abstract
A rotary furnace includes a drum and a frame supporting the frame for rotation about a nominally horizontal rotational axis. The frame and the drum are supported for pivotal movement about a horizontal pivotal axis. A door supported on the frame normally closes the front end of the drum and is selectively pivotal to an open position to facilitate charging of the drum. The door includes a pouring door which is openable to facilitate discharge of molten material from the drum.
