Strip cold rolling is an efficient, high-quality cold-rolled production process, many of its equipment , the control process is complex, but the tension rolling cold rolling strip production is an important part of the process , the accuracy of the rolling tension control stability and has a great impact on the quality of the finished strip . Thus, the strip tension control study has important practical significance. In view of this , the paper Fujian Casey Steel Corporation 1250mm five -stand tandem cold rolling mill as the basis for the entire mill tension control system is studied . Firstly, to five -stand tandem cold rolling mill uncoiler , looper tension control system for the study, the analysis of the tension control system uncoiler dynamic compensation , roll diameter calculation and looper tension control theory based on the proposed open-book machine, looper tension control system 1250mm five -stand tandem cold rolling mill in constant tension control implementations. Secondly, the five -stand tandem cold rolling mill for the object, the tension between the rack control system were the focus of analysis . The establishment of a model based on the tension , according to indirect and direct tension with the tension resulting object models for the design of tension regulator , gives the corresponding parameter calculation process, and the results of the application . Finally, the details of the five-stand tandem cold rolling mill 1250mm automatic control system hardware and software configurations, as well as functional studies ISaGRAF programming software .
