Abstract 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-segment 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.
