在过去的１２年里，美国的钢铁企业一直采用一种轧机监测程序来探测轧机的震颤状况和工作辊轴承的缺陷。通过研究发现，工作辊轴承中的缺陷是因产生震颤的振荡引起的。美国ＵＳＳ公司对其艾尔文厂的５机架串列式轧机进行监测。自从１９８６年实施监测程序开始，由于震颤被大大
For the past 12 years, U.S. steelmakers have been using a mill monitoring program to detect mill tremors and work roll bearing defects. Through the study found that the work roll bearing defects caused by the oscillation caused tremor. USS US Company monitors its 5-stand tandem mill at Al Wynn Plant. Since the beginning of the monitoring program in 1986, tremor has been greatly increased
