Abstract

Bei einem Verfahren zum Verzinken eines Bandes (1) wird das Band (1) kontinuierlich mit Zink beschichtet, anschließend zur Bildung einer Zn-Fe-Schicht einer Wärmebehandlung in einem Durchlaufofen (10, 11) und weiters einer on-line-Kontrolle der Zinkschicht unter Messen des Eisengehaltes der Zinkschicht unterzogen, wobei der Verzinkungsvorgang in Abhängigkeit des Eisengehaltes der Zinkschicht gesteuert wird.
Um ein Band (1) mit einem definierten Schichtaufbau unter Sicherstellung einer gleichmäßigen Qualität herstellen zu können, wird ein Wert des Eisengehaltes der Zn-Fe-Schicht als Führungsgröße bestimmt, der Istwert des Eisengehaltes der Zn-Fe-Schicht mit der Führungsgröße verglichen und eine Regelabweichung über einen Regler (19) durch eine Änderung der als Stellgröße dienenden Heizleistung des Durchlaufofens (10, 11) ausgeglichen (Fig. 1).
