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. The invention relates to a rolling mill arrangement for Manufacture of seamless steel tubes. To a tube whale z plant with low investment costs to find at the pipe with a minimum of procedural steps can be produced without intermediate heating proposed having a one behind the other rotating guide discs equipped Schräwal dwarf (3) for punching the block, one with rotating Guide disks equipped cross rolling mill (4) for Stretching and a reduction or sizing mill (5) for Finish rolling the pipe.
