| 摘 要： | 在全连续带钢酸洗机组中,开卷机张力对带钢质量有重要影响.为保证带钢质量设计了无张力反馈的开卷机张力开环控制系统.详细论述了如何通过对变频器转矩设定值的准确计算来控制张力,以及在调试过程中摸索出的断带保护方案.结合唐山建龙冷轧厂带钢酸洗机组的工程实例,采用罗克韦尔1336FORCE变频器控制开卷机张力,验证了张力开环控制系统的可靠性.

| Abstract: | Since the payoff tension has a great influence on the strip quality in the continuous-pickling line,we designed an open loop tension control of the payoff.In the paper,how to calculate the control tension by setting the torque reference is analyzed in detail.The strip breaking protection scheme is found out during the trail operation.This method is applied in Tangshan Jianglong continuous-pickling line by using the inverter of Rockwell 1336 FORCE Drive to control the tension.The reliability of the open loop tension control is verified. |
