摘　　要：针对济钢中板厂可逆式四辊轧机异常弹跳导致的设备故障多、轧机刚度降低、板型控制难度加大等问题进行分析,认为换辊托盘产生不均匀的塑性变形是轧机异常弹跳的根本原因,提出了改进托盘制造工艺防止不均匀的超量塑性变形、调整托盘受压区尺寸防止发生弓形结构等措施。Analyzes the problems such as more device stoppages, lower mill rigidity value, more difficulties on plate shape controlling etc, which caused by singular springing on the four high reversing plate mill of JigangThus, the basic reason is thought to be the inhomogeneous plastic deformation on the bracket of roll changing To make the bracket better, countermeasures such as improving manufacturing technology to prevent extra inhomogeneous plastic deformation and adjusting the size of deformed area to guard against bow structure etc are put forward
