摘　　要：为了提高不锈钢热连轧的宽度控制水平,通过粗轧短行程控制来改善带钢头尾宽度控制曲线。根据热轧粗轧短行程控制理论,分别使用了三段折线式和两段抛物线式来进行控制,同时根据带钢头尾的宽度偏差对短行程曲线进行自学习。现场投用表明:这种粗轧短行程控制模型能够明显地改善中间坯的头尾偏差,提高带钢成材率。To the problem of width excess of stainless steel on hot strip mill, short stroke control （SSC） on rough rolling mill was used to improve the width control curve of strip head and tail ends. Based on the principle of SSC, the model of three-seg- ment polyline and two-stage parabolic were separately used. In addition, self-learning method of SSC which is based on the width deviation of head and tail ends was applied. The results prove that the control accuracy of head and tail ends of middle slab can be improved by using this model of SSC on rough rolling mill, so the rolling yield can be improved.
