Abstract

The paper considers the dynamic mathematical model of correlated electrical systems (automated electric drives and systems controlling performance data) of the continuous train of the wide-strip hot-rolling mill. The model has a correlated structure containing the models of systems for roll speed, automated strip gauge, tension and loop and electric drive speed mode control. Interrelation of the above facilities has a form of a dynamic model of strip in the inter-stand gap, models of generating torque, pressure and lag at rolling. Adequacy of the model to the issue under consideration was checked by comparing transient process modeling results with experimental ones. The most complex dynamic mode of strip gripping by rolls of three last stand of the continuous train was under investigation. It was established that percent parameter deviations ranged within ±15%; that is tolerable at modeling complex facilities. The developed mathematical model is applied for study of the control systems and algorithms elaborated for the 2,000 and 2,500 mm mills of OJSC Magnitogorsk Iron and Steel Works.

宽带热轧机连续传动机电系统数学模型

本文研究了宽带热轧连轧机相关电气系统(自动电气驱动系统和控制性能数据系统)的动态数学模型。该模型具有关联结构，包含轧辊速度系统、自动带材厚度系统、张力系统和环路系统以及电驱动速度模式控制系统的模型。上述设施的相互关系有带钢在机架间间隙的动态模型、轧制时产生扭矩、压力和滞后的模型。通过将瞬态过程建模结果与实验结果进行比较，验证了模型对所考虑问题的充分性。研究了连续列车三尾架轧辊夹持带钢最复杂的动力学模式。结果表明，参数偏差百分比在±15%以内;这在模拟复杂设施时是可以容忍的。所建立的数学模型应用于马格尼托格尔斯克钢铁公司2000和2500毫米轧机的控制系统和算法的研究。
