摘要
针对六辊轧机工作过程中存在的带材跑偏、工作辊与中间辊及支撑辊因磨损不对称等因素而引起的实际辊型不对称、来料板形及断面形状呈不对称分布等非对称轧制问题,以某冷轧厂1220平整机组为研究对象,定量分析了带材跑偏、来料断面形状不对称、工作辊辊型不对称、中间辊辊型不对称和支撑辊辊型不对称等典型非对称轧制情况下轧机的出口板形分布规律,并在此基础上研究了非对称轧制过程中的板形控制策略,提出了相应的板形控制技术,并将其应用到生产实践,编制出一套《1220六辊平整机组非对称轧制过程板形控制软件》,利用该软件定量分析了相关技术的板形控制效果,为机组的设备改造以及最终解决非对称轧制所带来的板形问题奠定了坚实的基础。
The problems of asymmetric rolling including asymmetric roll shape,asymmetric strip shape and section shape distribution are caused by the factors such as strip wondering,asymmetric wearing of work roll,middle roll and back-up roll in the working process of six-high mill roll.For these problems,taking the 1220 temper mill group as the object,the distribution law of the exit shape in the typical asymmetric cases including strip wondering,asymmetric section shape,asymmetric roll shape of work roll,middle roll and back-up roll was quantitatively analyzed.Then the strategy of the shape control in the process of asymmetric rolling was studied,the corresponding technology was put forward and applied into practical production,and the program of 1220six-high temper roll group shape control in the process of asymmetric rolling software was established.Using this software,the shape control effect about related technology was quantitatively analyzed,which lays the foundation for the equipment modification and the plate shape problem because of the asymmetric rolling.
