摘要：

通过对冷轧机垂直振动的分析，得出适当调整乳化液的性能和减小其浓度有利于抑制垂振。进行调整时发现，机架间乳化液的窜流问题严重影响了乳化液的调整效果，基于此原因从机架间喷射梁、张力辊、上下挡液板、吹扫梁、穿带导板等方面分析了乳化液窜流的原因，并提出了有效的改进措施。确定主要改进措施为：调整机架间喷射梁位置；后移张力辊与坝辊的位置，增加乳化液回流量；将吹扫梁改为大角度折形梁；改进挡液板，增加弧形沟槽；改进穿带导板，利于乳化液下落回流等。

Based on the analysis on vertical vibration of cold rolling mill, the vertical vibration can be controlled effectively by adjusting performance of the emulsion and diluting emulsion concentration. It was found that crossflow of emulsion between two racks affected the adjustment on emulsion seriously. The causes of crossflow were analyzed from inter-rack jet beam, tension roll, upper and lower fluid baffle plate, purge beam, threading guide plate, etc. After that, the improvement measures were put forward, namely, adjusting jet beam position between two racks, moving the tension roll and the dam roller backwards, increasing the return flow rate of emulsion, changing purge beam shape as the zigzag with big angle, modifying fluid baffle to increase the arc groove, and improving threading guide to help emulsion reflux, etc.
