Abstract

In flatness measurement system, the flatness measuring signal can be affected by the flatness roll deflection. The flatness roll stress was analyzed and the flatness roll deflection model was obtained by using the influence function method in this paper. The model has been developed based on the deformation of flatness roll in rolling and compensating curve has been obtained. The results indicated that the setting curve of flatness is preferably accordant with the curve of online measuring flatness, and good strip flatness can be obtained.
