Abstract
A method for preadjusting and controlling strip planarity in flexible single-pass and reversing rolling of a strip-shaped material web using at least one work roll pair forming a roll gap and back-up rolls for the work rolls, and devices for roll adjustment, roll bending, roll displacement and roll balancing. The method includes, when rolling a thickness ramp for adjusting a desired strip profile shape over the strip width, determining corresponding adjustment parameters by accessing on-line a multidimensional data matrix produced off-line through a FEM model for all adjustment ranges of rolling force, roll displacement and bending control at all occurring strip widths.
