Analysis of the Axial Force of Roll and Torsion Vibration of Main Drive System of Plate Mill

A 3500mm plate mill often arise the accidents of bearing damage and the back-up roll rupture.Therefore,the axial forces of roll and the torsion vibration of main drive system of mill were analyzed. The countermeasures were put forward of reducing the gap between the bearing box and slide plate of stand, and the distance of drive parts.The production practice showed that good effect had been achieved.
