1420UCM酸轧机组液压弯辊控制系统

Roll Bending System for 1420 UCM PL-TCM

介绍了梅钢酸洗连轧1420UCM机组液压弯辊控制系统,阐述了系统配置、机械结构和控制方法,介绍了工作辊弯辊系统中弯辊控制模式,实现了机组在轧制模式时正、负弯辊间无扰动切换。实际生产表明,该系统响应时间小于100ms,精度控制在±3%内,具有响应速度快、控制精度高等特点,控制性能完全符合考核指标,为机组的自动板形控制打下了良好基础。

The control system of roll bending for 1420UCM PL-TCM(PL-TCM:Pickling Line and Tandem Cold Mill system)at Meigang is introduced,the system configuration,mechanical structure and control method of the system are described.In the third part,the control method of WRBS(work roll bending system)in bending on mode is explained.The WRBS′s undisturbed switching between positive and negative bending in rolling mode is realized by the method.The practical production indicates that the response time is less than 100 ms,control precision is controlled within±3%,so the system has the characteristics of fast response speed,high control precision and the WRBS performance completely conforms to the Guarantee figures,and it provides excellent foundation to automatic shape control.It has the extensive applicability.
