Abstract (en)

A rolling mill including a split type backing-up roll, which can form a crown pattern most suitable for control of a sheet configuration of given strip to be rolled, is disclosed herein. Outer diameters of a center backing-up roll (3a), quarter backing-up rolls (3b) and side backing-up rolls (3c) are made identical, an axis of the center backing-up roll (3a) and axes of the both side backing up rolls (3c) are arranged as displaced from an axis of a roll shaft in the opposite directions to each other, axes of the both quarter backing-up rolls (3b) are displaced from the axis of the above-mentioned roll shaft in the direction crossing at a desired angle with a straight line connecting the axis of the above-mentioned center backing-up roll (3a) and the axes of the above-mentioned side backing-up rolls (3c), and thereby it is made possible to obtain many kinds of crown patterns. Similar rolling mills including a split type backing-up roll having a number of different constructions are also disclosed. <IMAGE> <IMAGE>
