Abstract
A rolling mill is disclosed in which, in order to improve the quality of rolled products, a work roll with a small diameter is used and is offset by a predetermined distance from the reduction line and the horizontal bending force is exerted to the small-diameter work roll through a horizontal intermediate roll from a sectionalized roll so that flatness of a workpiece being rolled is controlled. The small-diameter work roll, the horizontal intermediate roll and the sectionalized roll are so arranged that their axes are maintained in coplanar relationship with each other. Therefore the axes of these rolls can be automatically aligned with a high degree of precision.
