精轧机组的工作辊,经常因为工作辊弯辊装置的液压锁紧缸动作异常,拖延精轧机组工作辊换辊时间,严重影响热轧厂的设备运转率。通过弯辊装置液压锁紧缸故障总结和工作辊弯辊装置原理、结构分析,对工作辊弯辊装置操作侧与传动侧液压锁紧缸进行改造。
The work rolls of finishing rolling mills often work abnormally because of the hydraulic locking cylinder of the work roll bending device, which delays the roll changing time of the work rolls of the finishing rolling mill and seriously affects the equipment operation rate of the hot rolling mill. Through the summary of the hydraulic locking cylinder of the bending device and the principle and structure analysis of the bending device of the working roller, the hydraulic locking cylinder on the operating side and the transmission side of the bending device of the working roller is reformed.
