In order to be able to perform an adjustment to different operating settings and diameters of the work rolls, it is provided that the stripper chisel (6) is disposed in a horizontally displaceable stand roll table, wherein the movement of the stand roll table (6, 7, 8) is linked to the vertical movement of the lower work roll such that the stripper chisel (6) can be moved away from the work roll (5) when the lower work roll moves upward, and vice versa.

Description

Vorrichtung zur Verstellung des Abstandes der Abstreifermeißel Device for adjusting the distance of the scraper chisel
Die Erfindung betrifft eine Vorrichtung zur Verstellung des Abstandes der Abstreifermeißel vom Umfang der in den Einbaustücken eines Walzgerüstes lagernden Arbeitswalzen, bei der der Abstreifermeißel parallel zur Walzlinie in Richtung auf den Walzspalt und von diesem weg bewegbar ist.The invention relates to a device for adjusting the distance of the Abstreifwürißel from the scope of the chocks of a roll stand overlapping work rolls, wherein the scraper chisel is parallel to the rolling line in the direction of the nip and movable away therefrom.
In Warmwalzreversiergerüsten werden üblicherweise Ständerrollgänge eingesetzt, die eine Überleitung des Walzguts von der Arbeitswalze auf den nachgeschalteten Rollgang bzw. von dem vorgeschalteten Rollgang auf die Arbeitswalze gewährleisten. Der Übergang des Walzguts von der Arbeitswalze auf die Ständerrollgänge erfolgt in der Regel über einen Abstreifermeißel, der zwischen den Arbeitswalzenbaustücken befestigt ist oder in den Ständerrollentisch integriert ist.In hot rolling reversing stands usually stand roller tables are used, which ensure a transfer of the rolling stock from the work roll to the downstream roller table or from the upstream roller table on the work roll. The transition of the rolling stock from the work roll to the stand roller tables is usually via a scraper chisel, which is fixed between the work roll chocks or integrated in the roll stand table.
Ein Beispiel für einen verschiebbaren Abstreifermeißel ist aus der DE 33 12 009 A1 bekannt.An example of a displaceable scraper chisel is known from DE 33 12 009 A1.
Bei breiten Walzgerüsten (Walzgut breiter 3500 mm) hat die Erfahrung gezeigt, dass die Befestigung des Abstreifermeißels zwischen den Arbeitswalzenbaustücken Probleme mit sich bringen kann. Die Meißel müssen in ihrer Form in den Freiraum zwischen Arbeitswalze und Arbeitswalzenbaustück eingepasst werden, d. h. das Widerstandsmoment der Meißel ist limitiert und kann nicht immer den Anforderungen entsprechend ausgeführt werden. Dies kann zur Folge haben, dass die Meißel bei Belastungen durch das Walzgut derart stark verbogen werden, dass sie zur Anlage an der Arbeitswalze kommen oder sogar vollständig zerstört werden. Werden an die Meißel besondere Anforderungen gestellt auf Grund einer großen Walzgutbreite, eines hohen Walzgutgewichts oder einer besonderen Beanspruchung wie beispielsweise in Aluminium-Gerüsten, so werden die Meißel in die Ständerrollgänge integriert, um sie steifer und widerstandsfähiger ausführen zu können. Bei einem Einbau der Abstreifermeißel zwischen den Arbeitswalzenbaustücken erfolgt die Anpassung der Position des Meißels an die unterschiedlichen Walzendurchmesser durch unterschiedliche Beilagen, so dass es möglich ist, einen konstanten Spalt zwischen der Arbeitswalze und dem Meißel einzustellen. Die Meißel bleiben während des Betriebs in einer fixen Position zur Arbeitswalze und bewegen sich mit dem unteren Arbeitswalzensatz nach oben oder unten, wenn eine Verstellung der Passline, z. B. durch eine hydraulische Anstellung unten im Gerüst, erfolgt. Dies hat zur Folge, dass sich die Position des Meißels zum Ständerrollgang verändert, da die Ständerrollgänge in einer fixen Position im Ständer montiert werden. Durch die sich verändernden Abstände zwischen Meißel und Ständerrollgang kann es zu Problemen bei der Überleitung des Walzgutes kommen, was vor allem nicht akzeptabel ist, wenn besondere Anforderungen diesbezüglich gestellt werden, wie z. B. in Aluminiumwalzgerüsten.For wide rolling stands (rolling stock wider 3500 mm) experience has shown that the attachment of the scraper chisel between the work roll chocks can cause problems. The chisels must be fitted in their shape in the space between the work roll and work roll chock, ie the moment of resistance of the chisel is limited and can not always be carried out according to the requirements. This can have the consequence that the bits are so strongly bent during loading by the rolling stock that they come to rest on the work roll or even completely destroyed. If special demands are placed on the chisels due to a large rolling stock width, a high rolling stock weight or a special load, such as in aluminum scaffolds, the chisels are integrated into the upright roller tables in order to make them stiffer and more resistant. When installing the scraper chisel between the work roll chocks, the adjustment of the position of the chisel to the different roll diameters is made by different shims, so that it is possible to set a constant gap between the work roll and the chisel. The chisels remain in a fixed position to the work roll during operation and move up or down with the lower set of work rolls when adjustment of the pass line, e.g. B. by a hydraulic employment down in the framework takes place. This has the consequence that the position of the chisel changed to the stator roller table, since the stator roller tables are mounted in a fixed position in the stand. Due to the changing distances between the chisel and stand roller table, there may be problems in the transfer of the rolling stock, which is unacceptable especially if special requirements are made in this regard, such as. B. in aluminum rolling stands.
Bei einer Integration der Abstreifermeißel in den Ständerrollgang können die Meißel hinsichtlich ihres Widerstandsmoments frei gestaltet werde, so dass sie in der Lage sind, hohe Belastungen, die aus dem Walzprozess resultieren, aufzunehmen.With integration of the scraper chisel into the upright roller table, the chisels can be freely designed in terms of their resistance moment, so that they are able to absorb high loads resulting from the rolling process.
Bei einer Veränderung der Position der unteren Arbeitswalze während des Walzbetriebs, z. B. durch eine hydraulische Anstellung unten im Gerüst, gibt es bislang jedoch keine technische Lösung, die es ermöglicht, den Spalt zwischen Arbeitswalze und Abstreifermeißel in jeder Betriebsstellung konstant einzustellen.When changing the position of the lower work roll during the rolling operation, for. B. by a hydraulic adjustment down the scaffold, there is so far no technical solution that makes it possible to set the gap between the work roll and scraper chisel in each operating position constant.
Aufgabe der Erfindung ist es daher, den Abstreifermeißel in den Ständerrollgang zu integrieren und dabei die Position des Meißels an unterschiedliche Betriebsstellungen und Durchmesser der Arbeitswalzen anpassen zu können, um so den Spalt zwischen Meißel und Walze immer konstant zu halten.The object of the invention is therefore to integrate the scraper chisel in the upright roller table while adjusting the position of the chisel to different operating positions and diameter of the work rolls, so as to keep the gap between the chisel and roller always constant.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, dass der Abstreifermeißel an einem horizontal verschiebbaren Ständerrollentisch angeordnet ist, wobei die Bewegung des Ständerrollentisches mit der vertikalen Bewegung der unteren Arbeitswalze verknüpft ist, so dass der Abstreifermeißel von der Arbeitswalze weg bewegbar ist, wenn sich die untere Arbeitswalze nach oben bewegt und umgekehrt. Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und werden nachfolgend noch beschrieben.This object is achieved according to the invention in that the scraper chisel is arranged on a horizontally displaceable stand roller table, wherein the movement of the stator roller table is linked to the vertical movement of the lower work roll, so that the scraper chisel is movable away from the work roll, when the lower work roll after moved up and vice versa. Embodiments of the invention will become apparent from the dependent claims and will be described below.
Mit Hilfe der Erfindung ist es möglich, den Abstreifermeißel zur Überleitung des Walzguts in den Ständerrollgang zu integrieren und trotzdem in jeder Stellung der unteren Arbeitswalze einen konstanten Spalt zwischen Walze und Meißel einstellen zu können. Durch die Erfindung ist es möglich, die Position des Ständerrollentisches in Abhängigkeit der Position einer unteren hydraulischen Anstellung zu wählen. Damit können bei der Positionierung des Meißels sowohl die unterschiedlichen Arbeitswalzendurchmesser berücksichtigt werden wie auch die unterschiedlichen Positionen der unteren Arbeitswalze, die durch die untere hydraulische Anstellung vorgegeben werden.With the help of the invention, it is possible to integrate the scraper chisel for the transfer of the rolling stock in the stator roller table and still be able to set a constant gap between the roller and the chisel in each position of the lower work roll. By the invention it is possible to choose the position of the stator roller table as a function of the position of a lower hydraulic adjustment. Thus, both the different working roll diameter can be considered in the positioning of the bit as well as the different positions of the lower work roll, which are specified by the lower hydraulic adjustment.
Diese konkrete Anforderung leitet sich aus den Betriebsbedingungen ab, die z. B. in einem Aluminium-Reversiergerüst mit einer max. Walzgutbreite von 4000 mm, einem max. Walzgutgewicht von 20 to und einer hydraulischen Anstellung unten im Gerüst vorliegen. Aluminium hat die Eigenschaft, dass es im heißen Zustand dazu neigt, an metallischen Oberflächen anzuhaften. Die hat zur Folge, dass die Abstreifermeißel in Aluminium-Walzgerüsten mit einem kleinen Spalt (ca. 3 mm) an die Arbeitswalze herangebracht werden müssen, um sicherstellen zu können, dass sich das Walzgut von der Walze löst und nicht in den Spalt zwischen Meißel und Arbeitswalze einläuft.This concrete requirement is derived from the operating conditions, the z. B. in an aluminum reversing mill with a max. Rolling stock width of 4000 mm, a max. Rolling stock weight of 20 to and a hydraulic employment below in the framework. Aluminum has the property that when hot, it tends to adhere to metallic surfaces. This has the consequence that the scraper chisels in aluminum rolling stands with a small gap (about 3 mm) must be brought to the work roll to be able to ensure that the rolling stock from the roller and not in the gap between the chisel and Working roll enters.
Des Weiteren sollen ggf. Walzgutrückstände von der Arbeitswalze abgestreift werden, was zur Folge hat, dass der Meißel starken Belastungen ausgesetzt ist und entsprechen steif ausgeführt werden muss. Das Abstreifen der Walzgutrückstände von der Arbeitswalze muss darüber hinaus auch in jeder Betriebsstellung gewährleistet werden, so dass in jeder Stellung der geforderte Spalt einstellbar sein muss. Zur Einstellung unterschiedlicher Passlines werden Walzgerüste mit einer hydraulischen Anstellung unten im Gerüst ausgestattet, die es ermöglichen, die Oberkante der unteren Arbeitswalze auf unterschiedliche Niveaus anzuheben bzw. abzusenken. Neben der Einstellung der Passline ermöglicht die hydraulische Anstellung auch eine Regelung der Walzgutdicke, d.h. die Dicke das Walzgut kann über die gesamte Walzgutlänge innerhalb bestimmter Toleranzen konstant eingestellt werden. Die Dickenregelung erfolgt permanent während des Walzbetriebs, so dass die Position der unteren Arbeitswalze einer ständigen Änderung unterlegen ist. Diese Positionsänderung der unteren Arbeitswalze muss bei der Einstellung des Spalts zum Meißel berücksichtigt werden. Die Erfindung soll nachfolgend an einem Ausführungsbeispiel erläutert werden.Furthermore, if necessary, rolling stock residues should be stripped off the work roll, with the result that the chisel is exposed to heavy loads and must be carried out in a stiff manner. The stripping of Walzgutrückstände from the work roll must also be guaranteed in each operating position, so that in each position, the required gap must be adjustable. To set different passlines, rolling stands are equipped with a hydraulic adjustment at the bottom of the scaffold, which allows the upper edge of the lower work roll to be raised or lowered to different levels. In addition to the adjustment of the passline, the hydraulic adjustment also allows control of the rolling stock thickness, ie the thickness of the rolling stock can be set constant over the entire length of rolling stock within certain tolerances. The thickness control takes place permanently during the rolling operation, so that the position of the lower work roll is inferior to a constant change. This position change of the lower work roll must be taken into account when setting the gap to the chisel. The invention will be explained below using an exemplary embodiment.

Fig. 1 eine schematische Teildarstellung eines Walzgerüstes mit unterschiedlichen Anstellungen der unteren Arbeits- und StützwalzeFig. 1 is a partial schematic representation of a rolling stand with different jobs of the lower working and support roller
Das Walzgerüst ist nur teilweise dargestellt und mit 1 bezeichnet. In diesem Gerüst sind in Einbaustücken 2 und 3 die Stützwalze 4 und die Arbeitswalze 5 gelagert.The rolling stand is only partially shown and designated 1. In this framework, the support roller 4 and the work roll 5 are mounted in chocks 2 and 3.
An die Walzlinie anstellbar sind die Walzen 4 und 5 beispielsweise durch Hydraulikzylinder.Can be adjusted to the rolling line, the rollers 4 and 5, for example by hydraulic cylinders.
Beidseitig der Arbeitswalzen 5 sind die erfindungsgemäßen Ständerrollentische mit dem Grundrahmen 7, den Ständerrollen 8 und den Abstreifermeißeln 6 zu sehen.On both sides of the work rolls 5, the stand roll tables according to the invention with the base frame 7, the stand rollers 8 and the Abstreifermeißeln 6 can be seen.
Die horizontale Verstellung oder Verschiebung der Ständerrollentische erfolgt durch die Verstelleinrichtungen 9.The horizontal adjustment or displacement of the stator roller tables is carried out by the adjustment. 9
Der gesamte Ständerrollgang kann beispielsweise aus zwei wesentlichen Bauteilen aufgebaut werden, einem am Walzenständer gelagerten Schwenkrahmen 10 und einem Ständerrollentisch, bestehend aus einem Grundrahmen 7, auf dem die einzelnen Ständerrollen 8 und der Abstreifermeißel 6 montiert sind.The entire stand roller table can be constructed, for example, from two essential components, one mounted on the roll stand pivot frame 10 and a stand roll table consisting of a base frame 7, on which the individual stator rollers 8 and the Abstreifwürißel 6 are mounted.
Möglich ist auch eine Ausbildung, bei der ein Tragrahmen am Walzenständer befestigt ist, in dem der Ständerrollentisch verschiebbar angeordnet ist.Also possible is an embodiment in which a support frame is attached to the roll stand, in which the stand roll table is arranged displaceably.
Der Tragrahmen kann ein - oder mehrteilig ausgebildet sein.The support frame may be one or more parts.
Bei der vorher genannten Lösung ist der Ständerrollentisch in dem Schwenkrahmen horizontal verschiebbar angeordnet, wobei - bei beiden Ausführungen - die Verschiebung über Positionsgeber gemessen werden kann.In the aforementioned solution, the stator roller table is arranged horizontally displaceable in the pivot frame, wherein - in both versions - the displacement can be measured via position sensor.
Die Positionsgeber ermöglichen eine genaue Bestimmung der aktuellen Position des Ständerrollentisches, so dass es möglich ist, diesen in eine Positionsregelung einzubinden. Diese Positionsregelung ist verknüpft mit der Positionsregelung anderer Komponenten im Gerüst, so dass gewährleistet werden kann, dass sich der Ständerrollentisch immer in einer optimalen Position zu den Arbeitswalzen befindet. Dies bedeutet, dass sich der Ständerrollentisch und damit der Abstreifermeißel nach außen bewegt (von der Arbeitswalze weg), wenn sich die untere Arbeitswalze nach oben bewegt und umgekehrt. Zum Wechsel der Arbeitswalzen wird der Ständerrollentisch in die äußerste Position verschoben um zu gewährleisten, dass es beim Ausfahren der Arbeitswalzensätze zu keiner Kollision zwischen den Meißeln und den Arbeitswalzenbaustücken kommt.The position sensors allow an accurate determination of the current position of the stator roller table, so that it is possible to incorporate this in a position control. This position control is linked to the position control of other components in the Scaffolding, so that it can be ensured that the stand roller table is always in an optimal position to the work rolls. This means that when the lower work roll moves up and vice versa, the stand roll table and thus the scraper chisel moves outward (away from the work roll). To change the work rolls, the stand roll table is moved to the outermost position to ensure that there is no collision between the chisels and the work roll chocks when extending the work roll sets.
Die Erfindung kann Verwendung finden in allen Walzwerken, die mit einem Ständerrollgang ausgestattet sind und an die besondere Anforderungen hinsichtlich der Überleitung des Walzguts von der Arbeitswalze auf den Ständerrollgang gestellt werden.The invention can be used in all rolling mills, which are equipped with a stand roller table and are placed on the special requirements in terms of the transfer of the rolling stock from the work roll on the stator roller table.
Die horizontale Verschiebung des Ständerrollentisches kann beispielsweise durch eine hydraulische Verstelleinrichtung erreicht werden. Andere Antriebe, wie z. B. elektrisch betriebene Gewindespindeln, sind ebenfalls möglich.The horizontal displacement of the stator roller table can be achieved for example by a hydraulic adjusting device. Other drives, such. As electrically operated threaded spindles are also possible.
Wie vorstehend erwähnt, ist die horizontale Bewegung oder Verschiebung des Ständerrollentisches verknüpft mit der vertikalen Bewegung der unteren Arbeitswalze. Verknüpft heißt in diesem Fall, dass sowohl eine elektrische wie auch eine mechanische Kopplung der beiden Bewegungsarten konstruktiv möglich ist. As mentioned above, the horizontal movement or displacement of the stand roller table is associated with the vertical movement of the lower work roll. Linked in this case means that both an electrical and a mechanical coupling of the two types of movement is structurally possible.
