Abstract

Es wird ein Verfahren zur Verbesserung der Kontur gewalzten Materials und zur Erhöhung der gewalzten Materiallänge bei einem Walzprogramm bzw. zur freieren Gestaltung desselben hinsichtlich der Breitenabfolge der Bänder mittels axialer Verschiebung von Arbeitswalzen von zumindest einem Walzgerüst in Warm- oder Kaltwalzanlagen in Abhängigkeit eines Qualitätskriteriums in Form einer mathematischen Funktion, welches optimiert wird, gezeigt, wobei für mindestens ein Walzgerüst je ein Qualitätskriterium erstellt wird, das zumindest auf einen Teilabschnitt des Walzprogramms, der mehrere Walzvorgänge umfaßt, angewendet wird, und dass aufgrund der Optimierung des Oualitätskriteriums die jeweiligen Walzenverschiebungen für alle Walzvorgänge des betrachteten Teilabschnitts vorherbestimmt werden.It becomes a method of improving the contour of rolled material and increasing it the rolled length of material in a rolling program or for freer design the same with regard to the width sequence of the bands by means of axial displacement of work rolls from at least one roll stand in hot or cold rolling plants depending on a quality criterion in the form of a mathematical Function, which is optimized, shown, each for at least one roll stand Quality criterion is created that relates to at least a section of the rolling program, which comprises several rolling operations is applied, and that due to the optimization of the quality criterion the respective roll displacements for everyone Rolling operations of the section under consideration can be predetermined.
