ROLLER MADE FROM A COMPOSITE MATERIAL AND USED FOR HIGH-TEMPERATURE ANNEALING

摘要

A roller for a high temperature annealing line includes a cylindrical shell and an axial support element and including a spindle at at least one of its ends, and first and second keys fastened to the axial support element and each arranged in a respective first or second through opening formed in the shell. The first key is mounted to bear against a first circumferential bearing surface of the first through opening while the second key is mounted against a second circumferential bearing surface of the second through opening opposite to the first circumferential bearing surface of the first through opening in a circumferential travel direction. The first key is mounted to bear against the second longitudinal bearing surface of the first through opening, while the second key is mounted against the first longitudinal bearing surface of the second through opening opposite to the second longitudinal bearing surface.
