Die Erfindung bezieht sich auf ein Verfahren zum Walzen von Profilstäben aus Eisen oder anderen Metallen, die quer zur Walzrichtung örtliche, mehr oder weniger starke Erhöhungen oder Vertiefungen, z. B. Rippen, Nocken, sonstige Verstärkungen o. dgl., aufweisen, bei welchen das Vorwerkstück zwischen einer Oberwalze und einem als unteres Walzwerkzeug dienenden Tisch, derThe invention relates to a method for rolling profile bars from Iron or other metals that are localized transversely to the rolling direction, more or less strong elevations or depressions, e.g. B. ribs, cams, other reinforcements or the like, have, in which the preliminary workpiece between a top roller and a than lower rolling tool serving table, the

«o die örtlichen Vertiefungen oder Erhebungen enthält, hindurchgeführt werden.«O the local depressions or elevations contains, are passed through.

Es hat sich nun gezeigt, daß beim Walzen von Profilstäben vorerwähnter Art bei gleicher Umfangsgeschwindigkeit der Walze wieIt has now been shown that when rolling profile bars of the aforementioned type with the same Peripheral speed of the roller such as

Es wurde nun erfindüngsgemäß festgestellt, daß ein einwandfreier Profilstab dadurch hergestellt werden kann, daß man dem die geradlinige Bewegung ausführenden Tisch eineIt has now been established according to the invention that a flawless profile bar can be produced by giving the straight one Moving table one

S5 größere Geschwindigkeit erteilt, als der Umfangsgeschwindigkeit der Walze entspricht. So wurde beispielsweise beim Walzen von Stäben aus Eisen mit Querprofilen festgestellt, daß, wenn der Tisch eine gegenüber der Umfangsgeschwindigkeit der Oberwalze um 25 0/0 größere Geschwindigkeit aufwies, das Arbeitsstück in durchaus einwandfreiem Zustande aus der Matrize des Tisches herausgenommen werden konnte. Die Größe der Mehrgeschwindigkeit ist durch Versuch bei den einzelnen Metallen, aus denen die Werkstücke bestehen, leicht festzustellen.S5 granted a higher speed than the peripheral speed corresponds to the roller. For example, when rolling iron bars with transverse profiles, it was found that that when the table had a speed 25 0/0 greater than the peripheral speed of the top roller, the work piece taken out of the matrix of the table in perfect condition could be. The magnitude of the extra speed is determined by experimentation with the individual metals that make up the workpieces exist, easy to determine.
