摘要

针对冷连轧轧制规程目标函数之间存在耦合、相互制约、难以选择目标侧重的问题，采用了一种先优化后选择的方式设定轧制规程。构造了等功率裕度、板形良好和防打滑目标负荷，建立了多目标轧制规程目标函数，采用改进的免疫克隆多目标算法对唐山某钢厂冷连轧机进行轧制规程优化计算。试验结果表明，改进的免疫克隆多目标算法能够很快地收敛到Pareto前沿，并且解集的分布性良好；优化后的不同偏好轧制规程组合可以满足不同的选择要求。与原规程相比，各轧机的利用更加合理，提高了轧机的利用效率，改善了带钢板形和表面质量，并且减少了划痕的产生概率。

Abstract

Rolling schedule is set by the model of optimize first and then choice to solve the difficult problem of select weight，because there is coupling and restrict each other between objective functions. In order to improve the efficiency of mill，improve the plate shape and surface quality，selecting the power distribution，excellent flatness and the slip rate as objective functions，The rolling schedule of steel cold rolling mill in Tangshan is optimized by Improve Immune Clone Multi- objective Algorithm（IICMA）. The experiment results show that IICMA can guarantee convergence and improve the distribution degree of the population at the same time；and the optimized different preferences rolling schedules can meet the requirements of different choices. Compared with the original procedures，the use of the mill is more reasonable，flatness is better and the slip rate reduces to an acceptable level.
