CLECIM铝箔轧机异常断带故障查找及分析

Fault Finding and Analysis of Abnormal Strip Break in CLECIM Aluminium Foil Mill

介绍了CLECIM铝箔轧机控制系统的结构与功能,轧制过程中因控制原因出现异常断带,其故障查找的过程与方法。具体分析了因电机脉冲发生器异常丢速,引起控制系统的速度调节器饱和,给系统送出一个误信号而引起控制异常。

This article introduced the structure and function of the control system of CLECIM aluminum foil mill, the process and method of fault finding about abnormal strip break in the process of rolling due to control reasons. The abnormal speed loss of the motor pulse generator causes the saturation of the speed regulator in the control system, which is analyzed in detail, and an error signal is sent to the system to cause the abnormal control.
