摘　　要：基于热连轧生产线二级模型中板形自适应模型的研究,提出了该生产线轧辊凸度自适应控制算法的不完善性及相关优化措施。通过对轧辊自适应模型程序和相关参数的优化,在轧制同类钢种和规格时,辊系凸度的各自适应项均能够向着更稳定的方向对凸度进行调节,使该生产线轧制的钢带凸度全长命中率由优化前的91.9%提高到优化后的94.5%。The improvement and the optimization for the roll stack crown learning model were proposed on the basis of the shape model adaptation learning research of L2 system on the hot strip rolling line.When rolling the same steel grade of the same norm,the adaptation values of the roll stack crown worked more steadily by using the optimizations of the model program codes and the parameters.The strip crown precision hit ratio was also increased from 91.9％ to 94.5％.
