Abstract

Die Erfindung betrifft ein Verfahren zum Walzen von Flachmaterial und Band in einem Walzgerüst mit Arbeits- und Stützwalzen sowie mit Einrichtungen zum Ausbalancieren sowie zur positiven und negativen Biegung der in ihren Einbaustücken gelagerten Arbeitswalzen. Folgende Verfahrensschritte werden dabei durchgeführt:
  • a) die Arbeitswalzen werden bei geöffnetem Walzspalt mittels der Kolben-Zylindereinheiten für die positive und negative Walzenbiegung spielfrei gegen die Stützwalzen gefahren,
  • b) der Druck in den Kolber-Zylindereinheiten für die negative Biegung und damit die negative Walzenbiegekraft wird so eingestellt, daß mit dieser Einstellung die für die Profil- und Planheitsregelung der Walzstraße unter Last notwendige Walzspaltkorrektur erreicht wird,
  • c) der Druck in den Kolben-Zylindereinheiten für die Ausbalancierung und positive Biegung und damit die positive Walzenbiegekraft wird um die notwendige Ausbalancierungskraft höher eingestellt,
  • d) beim Einlaufend des Walzgutes erweitert die Walzkraft den Walzspalt auf die gewünschte Größe, wobei die erforderliche Ausbalancierungskraft automatisch von der Walzkraft übernommen wird,
  • e) beim Auslaufen des Walzgutes aus dem Walzspalt verringert sich dieser und die erforderliche Ausbalancierungskraft wird automatisch durch die Zylindereinheiten für die positive Biegung wieder hergestellt.
