摘　　要：针对以往连退机组在辊型曲线的优化设计过程仅考虑通板稳定而不考虑到板形控制、仅采用分工艺段单独优化而不考虑全炉段协同设定的问题,在大量的现场试验与理论研究的基础上,既考虑到连退机组的通板稳定性又考虑到板形控制,同时还兼顾到炉内上下游工艺段之间的有机联系,构造出了相应的炉辊辊型优化目标函数,提出了一套适合于连退机组的全炉段炉辊辊型曲线综合优化设定技术,并将其应用到某1 550连退机组的生产实践,取得了良好的使用效果,有效地提高了机组的通板稳定性与出口板形质量,为现场创造了较大的经济效益,具有进一步推广应用的价值。Aiming at the problem that the design process of roll profile curve optimization of continuous annealing units in the past only considers the stability of the through plate,not the shape control,and only adopts the separate optimization of process sections without considering the coordinated setting of the whole furnace section.On the basis of a large number of field tests and theoretical studies,considering not only the stability of the through plate of the continuous annealing unit but also the shape control,but also the organic relationship between the upstream and downstream process sections in the furnace,the corresponding objective function of roll profile optimization is constructed,and a set of comprehensive optimum setting technology for roll profile curve of whole furnace section suitable for continuous annealing unit is put forward,which is applied to the production practice of a 1 550 continuous annealing unit and achieved good results.It has effectively improved the stability of the through plate and the quality of the exit plate of the unit.It has created greater economic benefits for the site and has the value of further popularization and application.
