摘要
某热轧厂投产多年,精轧机换辊系统存在机械设备精度不高、电气设备老化、维护费用昂贵等问题。为此,该系统进行大修改造。改造后的换辊自动化系统采用西门子TDC控制器,6SE70变频器,ET200M和ET200S远程站,WinCC人机界面和现场操作台。投入运行以来,该自动化系统控制功能达到设计要求,控制系统先进可靠,操作维护方便。
A hot mill has been formally on production for many years. There are some problems in the roll changing system of finishing mill. The precision of mechanical devices are not high,the electrical devices are seriously aging,and the maintenance costs are very high. So the system needed overhauling. The reformed system includes a Sie- mens TDC controller, the 6SE70 inverters,the ET200M and ET200S remote stations, the WinCC human machine interfaces and the local pulpits. During the operation, the control functions of the automatic system meet design requirements, the control system is advanced and safe,operation and maintenance is convenient.
