|
Abstract As the target of flatness control, flatness target curve is an important component of the closed loop feedback flatness control system. In order to improve the flatness of cold rolled strips, a basic flatness target curve was set dependent on the flatness discrimination model in revamp of the 1250 6-H reversing cold mill. For purpose of avoiding influence coming from temperature, coil shape as well as geometric error of winder, series of compensation curves were set in accordance with the rolling process and equipment condition in site. At the same time, additional manual curves were set which brought flexibility to flatness control. The applications show that the model of flatness target curve is capable in flatness control and is significant to obtain good flatness. Strip profile was effectively controlled and was met the need of following processing.
