Abstract

Die Erfindung betrifft ein Verfahren zur Steuerung der Rohrwanddicke in einer vielgerüstigen kontinuierlichen Streckreduzierwalzstraße mit Einrichtungen zur Messung der Rohrwanddicke hinter der Streckreduzierwalzstraße, einer Rechnereinheit zur Meßwertverarbeitung und einer Einrichtung zur Drehzahlsteuerung der Antriebsmotoren.
Dabei wird durch rechnergesteuerte Veränderung der Drehzahlen der Antriebsmotoren während des Rohrdurchlaufes die Gesamtstreckung konstant gehalten und dadurch die Innenpolygonbildung auf ein Minimum reduziert.
