本文由现厂实测数据使用逐步回归方法建立了计算机控制压下的ε—S模型,Jn模型以及Jn修正模型,为武钢轧板厂2800精轧机座实现计算机控制压下提供了数学模型,这套数学模型用算法语言编制了程序,在x—1电子计算机上进行了模拟规程计算,其计算结果与实测数据进行了比较,证明其与实测数据比较吻合,且负荷分配比较均匀,对成品尺寸控制亦提出了措施。 In this paper, the ε-S model, the Jn model and the Jn correction model under computer control are established by the step-by-step regression from the measured data in the factory, which provides a mathematical model for the computer controlled depressing of 2800 finishing mill block in WISCO rolling mill. The mathematical model has been programmed by using the algorithm language. The calculation of the simulation rules has been carried out on the x-1 computer. The calculated results are compared with the measured data, which proves that it is in good agreement with the measured data and the load distribution is more uniform. Also proposed measures.
