【摘要】 通过不同工况下的实测压力波动值分析 ,得出了压力模型可能达到的精度。宝钢 2 0 5 0热连轧压力模型精度比较高 ,“k—μ”估计方法主要的功能是实现前滑模型的自适应 ,同时也可以提高压力预报精度。动态设定 AGC投运不仅提高了厚控精度 ,而且提高了厚度、辊缝、压力自适应的效果。提出了轧件刚度 d(单位面积的硬度 )作为宝钢模型的基本量。经改进的宝钢 2 0 5 0热连轧压力计算模型便于推广应用。更多还原

【Abstract】 According to the fluctuation of measured rolling force in different work conditions,the accuracy of rolling force model has reached expected value In fact ,the rolling force estimation model on 2050 mm hot strip mill at Baosteel has high accuracy The “k μ”estimation method can improve rolling force estimation accuracy,and its most important effect is to realize self adaptation for forward slip model Dynamic setting AGC method not only improve gauge control accuracy,but also improve the self adaptation effect of gauge,gap,rolling force Rolling piece stiffness d is assumed as one basical value of Baosteel model and d —thd rigidity of unit area The improved rolling force model is easy to be applied更多还原
