摘　　要：以首钢集团某冷轧厂连续镀锌线出口段张力控制系统升级项目为背景,针对生产线出口段经常发生带钢滑落、带钢头部划伤、带钢采样长度精度差等问题,研制开发了新型张力控制系统。系统通过张力设定值自适应、正转矩自动切换、邻近段张力实际值自选择等功能模块,抑制了卷取机张力对检查站张力的影响,避免了出口段带钢滑落事故和带钢头部划伤现象的发生,提高了出口段带钢取样长度的精度,确保了镀锌生产线的连续稳定运行。The exit section tension control system of continuous galvanized line in a cold rolling mill of Shougang Group for the reconstruction project is the background of this paper. In order to solve some problems in exit section such as strip sliding, strip head scratching, and poor accuracy for strip sam- piing length. We develop a new type of tension control system. This system applies some control tech- nologies such as adaptive tension setpoint, automatic switching technology for positive torque control, actual value selection for tension and so on. These functions suppress coiler tension on tension of the inspection table, avoid the strip sliding accidents and the incidence of strip head scratching, improve the accuracy of the strip sampling length, and ensure stable operation of the continuous galvanizing line.
