Abstract

Die Erfindung betrifft ein mehrgerüstiges dornloses Streckreduzierwalzwerk mit einer Walzenkalibrierung für die aus jeweils drei Walzen bestehenden Walzensätze mit einer von der Kreisform abweichenden, die Formänderung im Querschnitt des Rohres berücksichtigenden und einem unrunden Rohraußendurchmesser entgegengewirkenden Kaliberform. Dabei sind die letzten Kaliber (Fertigkaliber) des Streckreduzierwalzwerkes an den Umfangsstellen lokal vergrößert, an denen der ansonsten zu erwartende Rohrdurchmesser des einlaufenden Rohres vom Sollmaß nach unten abweicht und an den Umfangsstellen lokal verkleinert, an denen der ansonsten zu erwartende Rohrdurchmesser vom Sollmaß nach oben abweicht.
