Modelling of Crown on Cold Rolled Aluminium Sheet

The quality demands of shape characteristics of strips have especially been increased recently by the modern industrial branches processing strips. The final shape of sheet is influenced by the construction and stiffness of mill stand and the shaping parameters through the deformation patterns of roll gap. The purpose of our research work was the modelling of shape-defects (crown) developing during cold rolling in order to increase the technological precision of production of sheets.
