摘　　要：在炉卷轧机张力控制中,带钢张力稳定与否取决于卷筒电机的转矩给定精度,转矩给定由张力给定(换算成转矩)和张力损失相加得到,张力损失包括带钢弯曲转矩、卷筒加减速转矩、摩擦转矩和带钢在槽口边缘隆起补偿转矩。介绍了安钢炉卷轧机卷取轧制的主要设备和工艺,对卷轧张力的控制方法进行了论述,介绍了变频器带速度限制功能的转矩控制功能。实际生产运行表明,卷轧张力稳定,运行可靠。In the steckel mill tension control, to keep the strip tension constant is depended upon accuracy of torque reference of coiling drum drive,the torque reference will be the tension reference （converted to torque） plus loses. Loses to tension include the bending torque, acceleration/deceleration torque, windage and friction torque and drum knuckle torque offset in tension control of steckel mill. The main equipments and processing of ANGANG steckel mill were introduced, the methods of tension control and the function of converter torque control with speed limit function was introduced. In practical production,tension of coilong drum is stable and operation is reliable.
