Abstract
A model to describe the curvature of the centerline of a strip at the delivery side during hot rolling can be used to predict the longitudinal shape of the strip after rolling, and can be useful when designing a controller to reduce camber generation. However, the existing model was obtained from studies about side-slipping, and is based on incorrect assumptions. This paper uses the definition of curvature and tangential angle to clarify why the assumptions of the former model are incorrect. Also, this paper proposes a new model for curvature of the centerline at the delivery side; this model is based on the assumption that the curved strip is generated only by the difference between the velocities of the sides of the strip. The accuracy of the proposed model is validated by FEM simulation.
