摘　　要：在大型高速连续退火机组中,多塔式立式活套中活套位置的平衡控制和活套内带钢的恒张力控制一直都是此类机组控制的重点和难点。本文提出一种用于多塔式立式活套位置平衡与恒张力控制的解耦技术,可有效抑制塔间位置平衡调节对活套内带钢张力的影响,实现与带钢张力控制完全解耦的活套位置平衡调节。通过在华东某冷轧厂1450mm连续退火机组工程的成功运用,证明该技术控制精度高、响应快、性能稳定,可在同类生产线上广泛应用。In high-speed continuous annealing lines（ CAL）,the position balance control and the constant tension control are the important and difficult points in the control of the multi-tower vertical looper. In this paper,a decoupling technology used in multi-tower vertical looper is proposed to achieve position balance and constant tension control. This technology can effectively suppress the strip tension disturbance generated by the tower position changing,and implemented the complete decoupling of looper position and strip tension. The successful application in a CAL for a cold rolling plant in East China indicates that the control technology has high precision,rapid response and stable performance. It can be widely adopted in high-speed CALs.
