摘    要：酸轧联机轧机入口恒张力控制效果直接影响轧制过程和成品质量。作者提出了一种基于机架调节补偿和饱和速度控制的轧机入口恒张力控制技术,该控制技术能有效抑制联机活套张力波动和轧机机架调节对轧机入口张力的影响。通过此控制技术在华北某冷轧厂酸轧联机工程的成功应用,证明该技术控制精度高、响应快、性能稳定,可在酸轧联机生产线上广泛应用。

Abstract: In coupled pickle line and tandem cold mill,product quality and running stability are directly affected by the performance of constant tension control at mill entry.In this paper,a technology for constant tension control at mill entry is proposed,which adopts stand compensation and speed saturation strategy.The disturbance to mill entry tension induced from looper tension fluctuation and stand adjustment is suppressed by the technology.The successful application in a coupled pickle line and tandem cold mill of a cold rolling plant in North China indicates that the control technology features high precision,fast response and stable performance.It can be widely adopted in coupled pickle line and tandem cold mill.
