Abstract

The invention discloses a graphite cylinder fixing device which comprises clamping discs located at the two ends of a graphite cylinder. The graphite cylinder sleeves a roller. The clamping discs areof an annular structure, and an internal thread is arranged at the inner ring of each clamping disc. External threads are arranged at the two ends of the roller. The inner rings of the clamping discsare in threaded connection with the two ends of the roller. The ends of the clamping discs are connected with the ends of the graphite cylinder through screws. A sliding groove is formed in the innersurface of the graphite cylinder. A guide rail is arranged at the outer surface of the roller, and the sliding groove is matched with the guide rail. According to the device, the graphite cylinder canbe conveniently installed on the roller and disassembled from the roller, and it is ensured that the graphite cylinder is not likely to loosen in the rotating process.

Description

technical field [0001] The invention relates to the technical field of graphite cylinder production, in particular to a graphite cylinder fixing device. Background technique [0002] Graphite cylinder is also called graphite carbon sleeve or high-temperature carbon sleeve. It is mainly used on the surface of the bottom roll of continuous annealing furnace as the main support for strip steel in the annealing furnace. It has incomparable advantages over other metal rolls and ceramic rolls. It is soft in texture, has lubricity to the strip steel and does not adhere to the oxidized and reducing substances on the surface of the strip steel; nodules are easy to fall off, and are not easy to cause damage to the strip steel. At present, the graphite cylinder is generally installed on the roller shaft, and it is easy to loosen when the roller shaft rotates. At the same time, the installation and disassembly of the graphite cylinder is time-consuming and laborious, and the installatio...
