Description
Walzenkalibrierung für Walzwerke zur Herstellung von T-, L:., Z- oder ähnlichen Profilstäben Die Erfindung betrifft einte WalzenkaLibrierung für Walzwerke zur Herstellung von T-, 1-, Z- oder ähnlichen Profilstäben, bei denen der eine Schenkel in der Längsrichtung wechselnde Schenkelstärken erhält, während derandere Schenkel in üblicher Weise gleichmäßige Stärke aufweist. Dies wird in besonders einfacher Weise erreicht durch eine neue Art der Walzenkalibrierung, mit der die richtige Werkstoffverteilung entsprechend der beabsichtigten unterschiedlichen Querschnitte bewirkt wird.Roll calibration for rolling mills for the production of T, L:., Z or similar profile bars. The invention relates to a roll calibration for rolling mills for the production of T, 1, Z or similar profile bars, in which one leg changes in the longitudinal direction obtained, while the other leg has in the usual manner uniform thickness. This is achieved in a particularly simple manner by means of a new type of roller calibration, with which the correct material distribution is effected in accordance with the intended different cross-sections.
Es sind bereits Walzensätze mit einer glatten und einer Kaliberwalze bekannt, die aber zur Herstellung von Walzstäben mit gleicher Wandstärke dienen und allgemein in Profilwalzwerken angewandt werden.There are already roller sets with a smooth and a caliber roller known, but they are used for the production of rolled bars with the same wall thickness and are generally used in section rolling mills.
Nach Erfindung wird das Profil bis zum vorletzten Stich wie jedes andere T-, L-, Z-Eisen gewalzt, im Fertigstich jedoch wird .eine Kaliberwalze benutzt, die entsprechend der zu- und abnehmenden Schenkelstärke des zu walzenden Profils an einer oder beiden Seiten ausgearbeitet ist, wodurch z. B. die Schenkel von T-Eisen in Längsrichtung der Profile abwechselnd einen stärkeren oder schwächeren Querschnitt erhalten, während die Gegenwalze zur Aufnahme des Walzdrukkes vollständig glatt ;ausgebildet ist. Es erfolgt so die Walzung des Steges in einem geschlossenen Kaliber, was in diesem Falle etwas Neues darstellt und walztechnisch bisher noch nicht durchgeführt wurde.According to the invention, the profile is rolled up to the penultimate stitch like any other T, L, Z iron, in the final stitch, however, a caliber roller is used, which is worked out according to the increasing and decreasing leg thickness of the profile to be rolled on one or both sides is, whereby z. B. the legs of T-irons in the longitudinal direction of the profiles alternately receive a stronger or weaker cross-section, while the counter-roller for receiving the rolling pressure is completely smooth; In this way, the web is rolled in a closed pass, which in this case is something new and has not yet been carried out in terms of rolling technology.
Abb. i zeigt ein solches Walzenpaar mit einer glatten Walzea und einer erfindungsgemäß kalibrierten Walze b, dessen Kaliber c entsprechend den zu- und abnehmenden Schenkelstärken an den Seiten d mehr oder weniger ausgearbeitet ist.Fig. I shows such a pair of rollers with a smooth roller a and one according to the invention calibrated roller b, the caliber c corresponding to the added and decreasing leg thickness on the sides d is more or less worked out.
Abb. z zeigt einen Schnitt A-A durch das Walzenpaar. Das durch dieses Walzenpaar a und b laufende Profile erhält durch die seitliche Kalibrierungd der Walze b zu- soder abnehmende Schenkelstärken.Fig. Z shows a section A-A through the pair of rollers. That through this Roller pair a and b is given running profiles by the lateral calibration of the Roller b increasing or decreasing leg thicknesses.
Abb. 3 und q. stellen in Ansicht und Schnitt als Beispiel ein nach der Erfindung hergestelltes T-Eisen mit zunehmenden Schenkelstärken dar.Fig. 3 and q. adjust in view and section as an example T-iron manufactured according to the invention with increasing leg thicknesses.
