Description

Walzenkalibrierung für Stopfenwalzwerke Die Erfindung betrifft eine Erweiterung des im Patent 575 529 enthaltenen Gedankens, bei Walzenkalibern für Pilgerwalzwerke neben den bekannten Sprung- und Arbeitszonen noch besondere öffnungs- oder Ausgleichzonen anzuordnen, um die Streckvorgänge im Kaliber möglichst auszugleichen. Es ist im Hauptpatent ausgeführt worden, daß es mit Hilfe der neuartig gestalteten Kaliber möglich ist, die Wandstärken unter das bisher übliche Maß zu verringern und weiterhin trotz stärkerer Abnahme die Materialbeanspruchung während des Walzvorganges zu vermindern. Da insbesondere bei Stopfenwalzwerken, den sogenannten Schwedenwalzwerken, nach Möglichkeit eine lange Bearbeitungszeit vermieden werden muß, um die Abkühlung des Materials je Stich gering zu halten, wird vorgeschlagen, den Gedanken des Hauptpatents 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.Roll calibration for plug rolling mills The invention relates to an extension of the idea contained in patent 575 529 of arranging special opening or compensation zones in roll calibers for pilger mills in addition to the known jump and work zones in order to compensate for the stretching processes in the caliber as much as possible. It has been stated in the main patent that it is possible with the help of the newly designed caliber 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 if possible in plug mills, the so-called Sweden mills, in order to keep the cooling of the material per stitch low, it is proposed to apply the idea of the main patent to the calibers of plug mills, so also with these in addition to the known Special opening zones must be provided for jumping and work zones. In this way it is possible to bring about a rapid and greater reduction in wall thickness.

Auf. deY Zeichnung ist schematisch in Fig. i ein Schnitt durch das alte Kaliber, in Fig.2 ein Schnitt durch das neue Kaliber dargestellt..On. The drawing is schematically in Fig. i a section through the old caliber, in Fig. 2 a section through the new caliber is shown.

Bei dem alten Kaliber sind lediglich die Sprungzonen a1, a2 und die Arbeitszonen cl, c2 vorhanden, während bei dem neuen Kaliber außer den Arbeitszonen a, a2 die öffnungszonen a3, a4 vorhanden sind, zu denen die Arbeitszonen cl, c2, c3, c4 hinzukommen. _With the old caliber only the jump zones a1, a2 and the Working zones cl, c2 are present, while in the new caliber apart from the working zones a, a2 the opening zones a3, a4 are available, to which the work zones cl, c2, c3, c4 are added. _
