Abstract

A mill for rolling strips or plates, comprising:
frames of the rolling stand, upper and lower crossbeams, screw-down means, upper and lower roll groups and roll chocks. The upper/lower crossbeam is respectively mounted on the upper/lower side of the frames, to which the screw-down means are fixed, and the screw-down means are located at the end portions of the upper crossbeam to enable the latter to move for adjusting roll gap. The roll chocks and the upper and lower roll groups are arranged between the upper and lower crossbeams.
Supporting blocks are placed between the roll chocks and the crossbeams, and the bearings are provided between the upper/lower roll groups and the roll chocks.
Both the bearings and the supporting blocks are positioned at the middle part of the rolls and in the area of the roll bodies.
