Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von Rohren (1) aus metallischem Werkstoff in einem Planetenschrägwalzwerk (2), bei dem eine Rohrluppe (3) dem Planetenschrägwalzwerk (2) zugeführt und zwischen einer Anzahl Walzen (4) und einem domförmigen Innenwerkzeug (5) zum Rohr (1) gewalzt wird. Um die Herstellung des Rohres zu verbessern, ist erfindungsgemäß vorgesehen, dass das Innenwerkzeug (5) zu dem Zeitpunkt, zu dem der Anfang (6) einer Rohrluppe (3) und/oder das Ende (7) einer Rohrluppe (3) in den Bereich der Walzen (4) eintritt, gegen die Förderrichtung (R) der Rohrluppe (3) aus seiner Arbeitsposition (8) um einen vorbestimmten Verschiebeweg (x) zurückgezogen wird und nachdem der Anfang (6) der Rohrluppe (3) und/oder das Ende (7) der Rohrluppe (3) den Bereich der Walzen (4) passiert hat wieder in seine Arbeitsposition (8) vorgeschoben wird. Des weiteren betrifft die Erfindung ein Planetenschrägwalzwerk.
