A METHOD FOR FORMING A COILER DRUM FOR A HOT ROLLING APPARATUS AND A COILER DRUM

摘要

A method for forming a coiler drum (5) for a hot rolling apparatus, in which method a jacket (6) is formed parallel to the rotation axis (X) of the drum. The drum (6) is formed of two or more elements (6a, 6b) placed next to each other in the axial direction (X), and the adjacent elements are joined to each other in a joint zone (10), and the outer surface of the joint zone is closer to the rotation axis than the outer surface of the jacket element next to the joint zone. The invention also relates to a coiler drum and a hot rolling apparatus.
