The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, the best combination of opening parameters was obtained.

2016-11-9 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 ...
