Abstract (en)
[origin: EP1481742A2] Computer-supported determination process comprises feeding starting parameters describing the metal strip before and after passing through the rolling mill to a material flow model, determining the material flow model in the strip width direction and feeding to a roller deforming model, feeding an actual value of the strip center position to the roller deforming module, determining the roller deforming model using the roller force progression and feeding to a theoretical determining unit, and determining the theoretical values for the profile and planarity adjusting parts. An independent claim is also included for a control computer for determining the theoretical values for the profile and planarity adjusting parts.
