  Walzenkaliber für Stopfenwalzwerke. 
 EMI1.1 
 



  Es ist im Hauptpatent ausgeführt worden, dass es mit Hilfe der neuartig gestalteten Kaliber möglich ist, die Wandstärken unter das bisher übliche Mass zu reduzieren und weiterhin trotz stärkerer Abnahme die Materialbeanspruchung während des Walzvorganges zu vermindern. Da insbesondere bei Stopfenwalzwerken, den sogenannten   Sehwedenwalzwerken,   nach Möglichkeit eine lange Bearbeitungszeit vermieden werden muss, um die Abkühlung des Materials je Stich gering zu halten, wird vorgeschlagen, den Gedanken des Hauptpatentes bei den Kalibern von Stopfenwalzwerken anzuwenden, also auch bei diesen neben den bekannten Sprung-und Arbeitszonen besondere Öffnungszonen vorzusehen. Auf diese Weise gelingt es, eine schnelle und stärkere Wandstärkenabnahme herbeizuführen. 



   Auf der Zeichnung ist schematisch in Fig. 1 ein Schnitt durch das alte Kaliber, in Fig. 2 ein Schnitt durch das neue Kaliber dargestellt. Bei dem alten Kaliber sind lediglich die Sprungzonen   al,   a2 und die

  Roller caliber for plug mills.
 EMI1.1
 



  It was stated in the main patent that with the help of the newly designed caliber it is possible to reduce the wall thicknesses below the previously usual level and to continue to reduce the material stress during the rolling process despite the greater decrease. Since a long processing time must be avoided, especially in plug mills, the so-called Sehweden mills, if possible, in order to keep the cooling of the material per pass low, it is proposed to apply the idea of the main patent to the calibers of plug mills, i.e. also to these in addition to the known ones Jump and work zones must be provided with special opening zones. In this way it is possible to bring about a rapid and greater reduction in wall thickness.



   In the drawing, a section through the old caliber is shown schematically in FIG. 1, and a section through the new caliber in FIG. 2. With the old caliber only the jump zones a1, a2 and the
