摘　　要：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 roll of finishing mill unit,the fault of the locking cylinder movement abnormality for the bending-up roll device is often ocured,because of the reason,the time of the changing roll for the finishing mill work roll is delayed and seriously affecting the rate of equipment operation in the hot rolling plant.By summing up the failure of the hydraulic locking cylinder for the bending-up roll device,and the principles and structure of the bending-up roll device for work roll is analyzed,the operation side and drive of the hydraulic locking cylinder for the bending-up roll device is transformed.

关 键 词：弯辊装置 液压锁紧缸 设备运转率
