Abstract The coupling relationship between edge drop and flatness is analyzed theoretically and decoupled for control of flatness and edge drop. An independent module of work roll bending compensation is set in the feedback control system. The work roll bending on five stands are adjusted based on the periodical change of work roll shift position to decouple the coupling between edge drop and flatness control and obtain the optimum flatness control.
