关于采用位移传感器参与活套张力闭环控制可行性的分析

Feasibility Analysis of Using Displacement Sensors to Participate in Closed-loop Control of Loop Tension

对于活套要进行活套高度和活套张力两方面的控制。传统的活套控制中,通过调整上游机架轧辊速度使活套高度维持在设定值附近,通过控制活套油缸液压力使机架间张力恒定。二者是一个耦合系统。消除两者间的干涉,使活套稳定工作,成为活套控制的重要课题。

For the loop,it is necessary to control both the height and tension of the loop.In traditional loop control,the height of the loop is maintained near the set value by adjusting the roller speed of the upstream frame,and the tension between the frames is kept constant by controlling the hydraulic pressure of the loop oil cylinder.The two are a coupled system.Eliminating interference between the two and ensuring stable operation of the loop has become an important issuein loop control.
