ABSTRACT:
A rotary tube furnace suitable for operation in controlled atmospheres at temperatures in the range of 1500.degree. to 2800.degree. comprises a generally horizontal rotatable graphite tube slidably supported on water-cooled split ring graphite bearings. The graphite tube is rotated by means of a stainless steel drive plate and is contained within a flexible atmospheric sealing assembly and enclosure for the containment of a selected atmosphere around and within the tube and allows for the co-current or counter-current flow of gas during operation. Radiation baffles in the interior of the graphite tube inhibit radiant heat loss at the ends of the tube. The graphite tube may be constructed in two or more sections having threaded ends for ease of installation as well as removal or replacement for maintenance purposes. A heating section of the tube is heated by a plurality of graphite electrical heating elements contained within an insulated heating chamber.
