摘　　要：针对河北某钢铁公司热轧卷板头尾超宽、通条宽度精度低经常造成废钢事故等问题,分析了原因并进行了优化。通过优化粗轧立辊短行程TDC程序、短行程二级模型权重系数以及立辊负荷分配等措施,热轧卷板宽度通条精度显著提高,控制水平居国内领先水平。In view of the problems such as the over-width of the head and tail of the hot rolled coil and the low precision of the pass width,which often cause the scrap accidents,the causes are analyzed and optimized.By optimizing TDC program of short stroke of vertical roll,weight coefficient of two-stage model of short stroke and load distribution of vertical roll,the pass precision of strip width in hot rolling is improved remarkably,and the control level is the leading level in China.
