摘要： 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 (1) with a centre bore (4) for the removal of centre defects or flaws arising from the manufacturing process, e.g. from casting or forging and at least an end part (2, 3), whereas the end part (2, 3) has no centre bore or a centre bore (5) with a diameter smaller than the bore diameter of the main part (1).

摘要： The invention relates to a roll bending device for the control of profile and flatness in the rolling of metal plates or strips. In particular the invention relates to the well known principle of roll bending by using hydraulic cylinders to modify the load distribution between rolls of a rolling mill stand and a rolled stock e.g. a metal plate or a strip in order to control the profile and flatness of the metal plate or strip. A special design to allow safe roll bending even at large roll gauges is presented. The new design allows safe operation even at large roll gauges and high side loads.
