引进冷连轧机厚控系统分析及改进方案

武钢、宝钢两套冷连轧机代表了冷连轧技术发展水平 ,用连轧张力理论对这两套冷连轧机的厚控系统作了深入的分析、讨论 ,给出了其中最主要厚控环节 -连轧AGC和张力AGC的数学模型。对宝钢厚控系统提出了改进方案 ,利用DAGC可以简便地实现穿带、正常轧制、抛尾 ,而不用分别采用APC、恒压力、压力AGC三种控制方式 ,并且DAGC实现恒压力控制有更高的稳定性。

Analysis and Improved Scheme for Imported Cold Continuous Rolling Mill Gauge Control System

The two sets of cold continuous rolling mill of Wusteel and Baosteel stand for the technology developed standard of cold continuous rolling,the gauge control system of the two sets of cold continuous rolling mill were analyzed and discussed deeply with the aid of continuous rolling tension theory,and the mathematic model of continous rolling AGC and tension AGC were given.The improved scheme for Baosteel gauge control system was put forward,and threading,rolling and tail out can be realized easily by adopting DAGC but not adopting APC,constant pressure and pressure AGC respectively, moreover, constant pressure control can be realized by employing DAGC with more stable.
