摘要
从振动纹的物理特征分析入手,阐述了振动纹与轧机振动之间的关系,通过对轧辊与磨床的振动测试和模态分析研究了轧辊辊系、工作辊轴承、主传动接轴和轧辊磨床对振动纹的影响。结果表明,振动纹是由板面振波由于对光的不同反射角度而引起的一种视觉现象;带钢振纹的产生有2种途径,一是轧机(平整机)发生了一定频率的振动,另一个是轧辊表面本身已有了振纹;可通过轧辊直径匹配法、定期监测滚动轴承倍频峰值、对磨床加装阻尼减振器、改变轧制速度和磨削速度、加强设备日常维护等措施对振动纹进行抑制。
Based on the physical characteristics of chatter marks, the interaction between marks and vibration ot rolling mill is described. The effect of rollers, work roller bearings, spindle coupling clamp and roll grinding machines on chatter marks was studied with vibration measurement and mode analysis for both mill and roll grinding machine. The results show that chatter marks are a visual phenomenon caused by waves on strip surface, moreover, there are two causes of chatter marks formation, one is that the rolling mill （temper mill） is vibrated at some frequency, the other is that there are marks on the surface of rollers. It is possible to control the marks by some measures such as matching of roller diameter, regular monitoring of multiple peak value of ball bearing vibration, use of damp absorb er on grinding machine, speed change of rolling and grinding, and more careful maintenance of equipment.
