摘　　要：为了提高热轧带钢的成材率、减少板坯头尾部的失宽量，在热连轧粗轧机组中采用了短行程控制。作者利用一种新型优化算法——遗传算法优化短行程控制曲线，解决了传统方法难以解决的优化问题。优化结果表明，板坯头尾部失宽量大幅度减小，失宽区域长度也有所缩短。At the roughing stands of hot tandem rolling, short stroke control was used for increasing yield and decreasing width deviation. The curve of short stroke control which can ,t be optimized with conventional methods was optimized with a new optimization algorithm—genetic algorithm. The results show the width deviation at ends is largely decreased and the length of the width deviation area is shortened.
