摘要
基于直流电机拖动的基本原理,结合冷轧薄板轧制过程中影响带钢张力波动的因素,分析了带钢张力转矩、摩擦风阻转矩、动态转矩与张力的关系,提出了一种张力控制数学模型,通过计算卷径、卷重、加速度等参数,调节电机电流的大小来保持带钢张力的恒定.设计了张力控制系统程序,经过两年多在某厂冷轧机组和平整机组张力控制中的应用实践,其控制误差保证在1%以内,能够完全满足工艺对张力精度的要求,具有实际应用价值.
The factors influencing the strip tension in cold rolling thin sheets were discussed.The relation of the tension with strip tension torque,friction windage torque and dynamic torque was analyzed by using the principle of DC motor drive,and a mathematic model for tension control was set up. According to the calculation results of the parameters,such as the steel diameter,weight and acceleration,the motor current was adjusted to keep the constant strip tension.The tension control system code was designed.More...
