Vibration can be caused by one or more factors at any given time, the most common being imbalance, misalignment, wear and looseness. Imbalance - A heavy spot in a rotating component will cause vibration when the unbalanced weight rotates around the machines axis, creating a centrifugal force. Nov 09, 2016 Rolling mill vibration is a worldwide problem, although it has been found that the mill structure defects are the main cause of vibration, but the inhibition measures are difficult to implement. So we discussed the rolling force parameters influence on rolling mill vibration and suppression measures from rolling technology in this article. The results show that the rolling force is increased ...
