Abstract

Die Erfindung betrifft eine Walzwerksanordnung zur Herstellung von nahtlosen Stahlrohren. Um eine Rohrwal­ zanlage mit niedrigen Investitionskosten zu finden, bei der das Rohr mit einem Mindestmaß an Verfahrensschritten ohne Zwischenerwärmung hergestellt werden kann, wird vorgeschlagen, eine Hintereinanderanordnung eines mit rotierenden Führungsscheiben ausgerüsteten Schräwal­ zwerkes (3) zum Lochen des Blockes, eines mit rotierenden Führungsscheiben ausgerüsteten Schrägwalzwerkes (4) zum Strecken und eines Reduzier- oder Maßwalzwerkes (5) zum Fertigwalzen des Rohres.
