Abstract 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.

Key words： continuous annealing unit optimization of roller profile through plate stability strip shape
