The present invention is to provide a polishing heating cylinder capable of reducing temperature variation inside and outside the cylinder significantly. The present invention provides a polishing heating cylinder comprising: a cylinder part having a pair of rotational axes protruding toward both end parts and formed in a hollow shape; flange parts installed at multiple positions in the hollow of the cylinder part; a heating part fixated to the flange parts to be arranged along the inner circumference of the cylinder part, and heated by having external power applied thereto; an air supply part connected to one of the pair of rotational axes to supply air through an air supply hole formed on the rotational axis; an air spray part penetrating the centers of the flange parts to be arranged inside the inner cylinder part, connected to the pair of rotational axes to have both ends connected to the air supply hole, and spraying the air that is supplied to multiple positions in different directions; and a rotation control unit for supplying a rotational force to the cylinder part. |
