Patent Abstract / Summary
Die Erfindung betrifft ein Betriebsverfahren für eine Walzstraße, die mehrere von einem Metallband zu durchlaufende Walzgerüste (F1-Fn) aufweist, wobei das Metallband nacheinander in wenigstens einige der Walzgerüste (F1-Fn) eingefädelt wird und das Metallband die Walzstraße unter stufenweiser Dickenreduzierung von einer Ausgangsdicke auf eine Zieldicke durchläuft, wobei das Verfahren eine Geschwindigkeitsregelung der einzelnen Walzgerüste (F1-Fn) mittels einer übergeordneten Prozessteuerung umfasst, und wobei wenigstens die Einlaufgeschwindigkeit des Metallbandes in die Walzstraße und/oder die Geschwindigkeit der Walzgerüste (F1-Fn) beim Einfädeln eines Bandkopfs und/oder eines Bandfußes oder eines geplanten Abschnittswechsels des Metallbandes in die Walzgerüste (F1-Fn) entsprechend einer Geschwindigkeitsvorgabe für das Metallband oder für Teile des Metallbandes geregelt wird.
