احصل على السعرAug 01, 2010Abstract The presence of several rolls in cluster cold rolling mills makes online vibration monitoring and failure analysis difficult. The dynamic behaviour of rolls strongly depends on the rolling pressure in the roll bite. Strip vibration applies a dynamic component on the rolling force acting on the work roll and may excite the resonance of the mill stand. This
