摘　　要：张力辊是冷轧镀锌机组重要的张力设备,影响张力辊打滑的因素主要包括辊面与带钢材质、带钢运行速度、张力辊辊型。基于速度控制和转矩控制的张力辊均可通过打滑判定,利用降低打滑辊的负载平衡系数对张力辊打滑进行有效遏制。通过对京唐冷轧镀锌线张力辊负载平衡进行系统优化,为张力辊的打滑判定与遏制提供了依据。Tension roll is an important tension equipment in cold rolling galvanizing unit.The main factors that cause tension roll slip include roll surface and strip material,strip running speed and roll shape.The tension roller based on speed control and torque control can be judged by the slip,and the slip of the tension roller can be effectively restrained by reducing the load balance coefficient of the slip roller.The system optimization of load balance of tension roller in Jingtang cold rolling galvanized line provides a basis for the determination and control of slip of tension roller.
