本文介绍了一种液压轧机厚度监(预)控系统,其原理是在轧机出、入口侧分别安装两台测厚仪,厚度设定值由操作台给定,其入口偏差提供给预控系统,出口偏差提供给监控系统。实验结果表明成品精度提高一倍。文章对实验结果进行了分析讨论,并提出了在应用中应注意的几个问题。 This paper introduces a hydraulic mill thickness monitoring (pre) control system, the principle is in the rolling mill, the entrance side of the two gages were installed, the thickness of the set value given by the console, the inlet deviation provided to the pre-control system , Export deviation to the monitoring system. Experimental results show that the accuracy of the finished product is doubled. The article analyzes and discusses the experimental results, and puts forward some problems to be noticed in the application.
