一、前言江苏铝厂的1400mm 铝带冷轧机采用HAGC-Ⅲ型带材厚度自动控制系统。该系统自1995年投入运行以来,其厚度控制精度一直不理想,产品的纵向厚度偏差为0.1±0.005mm。这样的产品精度,不能满足越来越激烈的市场竞争要求,因而,对 HAGC-Ⅲ型厚度自动控制系统的厚度控制功能进行改
First, the preface Jiangsu aluminum mill 1400mm aluminum cold rolling mill with HAGC-Ⅲ strip thickness automatic control system. Since the system was put into operation in 1995, its thickness control accuracy has been unsatisfactory, the product of the vertical thickness deviation of 0.1 ± 0.005mm. Such product accuracy, can not meet the increasingly fierce market competition requirements, therefore, the thickness of the HAGC-Ⅲ automatic control system thickness control functions to change
