Abstract
The invention relates to the design of multiple piece rolls, in particular backup rolls, for the use in metal rolling. The roll comprises a main part with a center bore for the removal of center defects or flaws arising from the manufacturing process, e.g., from casing or forging and at least an end part, whereas the end part has no center bore or a center bore with a diameter smaller than the bore diameter of the main part.
