摘　　要： 对单机架四辊冷轧机控制系统软件进行改造,在原有基础上增加周期变厚度轧制功能.为了适应带材轧制过程中辊缝的周期性变化,控制系统对机械设备参数、检测仪表设置提出特殊要求,开发了轧件微跟踪、周期变厚度监控AGC、变张力、变速度周期轧制等重要控制功能.利用改造后的控制系统进行轧制实验,实现对周期变厚度带材的轧制,获得了很好的轧制效果,轧制精度高,周期长度准确.轧制控制系统满足轧制要求. Through modifying the software control system of a single stand four-roll cold rolling mill,the functional capability of the rolling periodic longitudinal profiled strip（PLP strip） was increased.In order to adjust periodic roll gap variation during rolling,special requirements for control systems were made on mechanical equipment parameters and measuring instruments.Micro tracking,monitoring AGC（automatic gauge control）,rolling variable tension,rolling variable speed,and other important control functions were developed and improved.Through experiments with updated control systems,PLP strip rolling was implemented satisfactorily,with high precision rolling and accurate cycle length.The new rolling control system meets all requirements for rolling.
