Description

Maschine zum Entzundern von bandartigem Walzgut Die Erfindung betrifft eine Maschine zum Entzundern von bandartigem Walzgut mit zur Entzunderung des Gutes dienenden, sich folgenden, in der Höhenrichtung zueinander versetzt angeordneten Rollen. Die Erfindung besteht darin, daß die Rollen von verhältnismäßig kleinem Durchmesser sind, sich gegen Stützwalzen abstützen, und daß das Walzgut die jeweils höher liegende Rolle oben und die tiefer liegende Rolle unten umläuft. Infolge der Abstützung der zum Entzundern dienen-, den Rollen können Rollen kleinsten Durchmessers, also nicht biegungsfeste Rollen verwendet werden, wodurch eine stärkere Biegung des Walzgutes beim Umlaufen der Rollen als bisher erreicht und dadurch eine wirksamere Entzunderung des Gutes gewährleistet wird. Walzen von sehr kleinem Durchmesser zu verwenden und sie gegen Stützrollen abzustützen, ist bisher nur bei Walzwerken bekannt, nicht aber bei Entzunderungsmaschinen.Machine for descaling strip-like rolling stock The invention relates to a machine for descaling strip-like rolling stock with for descaling the stock serving, following one another, arranged offset from one another in the vertical direction Roll. The invention consists in that the roles of relatively small Diameter are supported against back-up rolls, and that the rolling stock each The higher-lying roll rotates at the top and the lower-lying roll at the bottom. As a result of Support for the descaling, the rollers can be rollers with the smallest diameter, so non-bend-resistant rollers are used, creating a stronger bending of the rolling stock when rotating the rollers than before and thus a more effective one Descaling of the goods is guaranteed. Rolls of very small diameter closed use and support them against support rollers, is so far only known in rolling mills, but not with descaling machines.

Auf der Zeichnung ist schematisch ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.An exemplary embodiment of the subject matter of the invention is shown schematically in the drawing shown.

Zum Entzundern des bandförmigen Walzgutes dienen die kleinen Rollen i bis 5, die sich gegen die größeren Rollen 6 bis io abstützen. Infolge des Abstützens der Rollen i bis 5 brauchen diese nicht biegungsfest zu sein, und ihr Durchmesser kann so klein wie möglich gewählt werden, um ein starkes Durchbiegen der- Bänder zu erreichen. Die sich folgenden Rollen i bis 5 sind in der Höhenrichtung versetzt angeordnet, und das Walzgut umläuft die jeweils höher liegenden Rollen i, 3 und 5 oben und die tiefer liegenden Rollen 2 und q. unten, wobei der Zunder vom Band gelöst wird. Die Rollen i bis 5 können in der Höhenrichtung verschiebbar in dem Lagerkörper der zugehörigen Stützwalzen gelagert werden und übertragen so den auf sie ausgeübten Druck auf die Stützrollen.The small rollers are used to descaling the strip-shaped rolling stock i to 5, which are supported against the larger rollers 6 to io. As a result of supporting of the rollers i to 5, these do not need to be resistant to bending, and their diameter can be chosen as small as possible in order to avoid excessive flexing of the ligaments to reach. The following roles i to 5 are offset in the height direction arranged, and the rolling stock revolves around the higher-lying rollers i, 3 and 5 above and the lower rollers 2 and q. below, with the tinder from the belt is resolved. The rollers i to 5 can be displaced in the height direction in the Bearing bodies of the associated back-up rollers are stored and thus transferred to they exerted pressure on the support rollers.

Nach Lösen des Zunders .vom Walzgut kann dieses dann, nachdem vorher noch durch Bürsten der Zunder vom Walzgut entfernt worden ist, gegebenenfalls durch ein Förderwalzenpaar hindurchgeführt und darauf aufgewickelt werden.After loosening the scale. From the rolling stock, this can then, after beforehand the scale has been removed from the rolling stock by brushing, if necessary by a pair of conveyor rollers are passed through and wound up thereon.
