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.
