活套是用来检测和调整相邻机架间的速度关系，实现无张力轧制的设备。主 PLC中设有活套调节器，活套调节器是根据检测的活套高度偏差，产生速度修 正信号，调整机架速度以维持活套高度（活套量）在给定值上不变，实现前后 机架速度秒流量平衡。活套的起落是通过起套辊，改变轧件的金属流动方向生 成的。使轧件在轧制过程中生成自由的弧形，保证轧制过程中无张力轧制。 起套辊伸出和收回信号来自轧件头尾跟踪信号。由于起套辊动作执行机构延 迟性，起套辊伸出信号要比预期到达的伸出位置，提前一个延迟时间。当轧 件尾端接近活套的前一机架时，开始收套，活套高度将按一定斜率下降为零， 以避免轧件甩尾，后起套辊收回。操作人员通过CIMPLICITYHMI人机接口系统与轧机控制系统交换信息，显示画 面采用中文汉字系统。系统提供了方便灵活的选择、设定和监控功能。采用 CIMPLICITY系统，操作人员可通过键盘和鼠标，对轧线参数进行手动设定， 也可对存贮的轧制程序直接调用，进行自动设定。操作工可通过屏幕方便地对 轧制程序表进行输入或修改。
