摘　　要：为了提高冶金钢板热轧辊辊形凸度控制能力,提出了一种基于遗传算法的面向轧辊磨损和凸度调节的自适应辊形设计方法。综合考虑凸度控制状态与轧辊磨损量,构建了相应的辊形适应度表达式,并利用遗传算法获得离散化状态的变凸度辊形曲线。研究结果表明:采用遗传算法自适应辊形,相对于CVC辊形的线性系数减小,位移和凸度间保持线性对应关系,可以达到准确的凸度控制效果。该研究具有很好的拓展性和灵活度,对提高轧制精度具有很好的指导意义。In order to improve the control ability of roll profile of hot roll of metallurgical steel sheet,an adaptive roll profile design method based on genetic algorithm for roll wear and profile regulation was proposed.Considering crown control state and roll wear amount,the corresponding roll shape fitness expression is constructed,and the discretized roll shape curve of varying crown is obtained by genetic algorithm.The results show that the linear coefficient of CVC roll shape is reduced by using genetic algorithm adaptive roll shape,and the linear correspondence between s and crown is maintained,which can achieve accurate crown control effect.The research has good extensibility and flexibility,and has a good guiding significance for improving the rolling precision.
