| 摘 要： | 为了满足某厂1580热连轧机宽度控制精度需求,提高宽展模型的广泛适用性,利用ANSYS/LS-DYNA有限元软件,对热轧粗轧区立轧--平轧过程进行了模拟.根据模拟数据,系统地分析了轧件宽度、厚度、轧辊直径、立辊侧压量和厚度压下量对"狗骨"宽展、自然宽展和绝对宽展的影响规律.利用模拟数据并结合现场数据构造了FES(finite element simulation)"狗骨"宽展模型和自然宽展模型,并建立了PSO-BP神经网络(粒子群BP神经网络).最后,FES宽展模型与PSO--BP神经网络相结合预报第1、3和5道次的宽展,其预报值与实测值误差在1mm以内的均达到了99%以上,达到了宽度控制的精度要求.

| Abstract: | In order to meet the need of width control precision for a 1580 hot strip mill and to improve the applicability of width spread models,the process of edge rolling-horizontal rolling in the rough rolling area was simulated by the finite element software ANSYS/LS-DYNA.The effects of width,thickness,roll diameter,reduction in width and reduction in thickness on 'dog-bone' width spread,natural width spread and absolute width spread were studied.The FES models of 'dog-bone' width spread and natural width spread ... |
