Description

Die Erfindung richtet sich auf eine Einrichtung zum vorzugsweise mindestens paarweise, insbesondere satzweisen, Handhaben und/oder Transportieren von Stützwalzen und/oder Arbeitswalzen eines Walzgerüstes zwischen dem in einer Walzhalle angeordneten Walzgerüst und einer Walzenwerkstatt sowie in der Walzenwerkstatt, umfassend eine quer zur Walzrichtung des Walzgerüsts vom Walzengerüst in die Walzenwerkstatt verlaufende Walzenwechselgrube mit einer Lokomotive als Verfahreinrichtung für mindestens ein Paar oder einen Satz ausgebauter Stütz- oder Arbeitswalzen und ein in der Walzenwerkstatt quer zur Walzenwechselgrube und diese querend sowie in oder gegen die Walzrichtung des Walzgerüstes verfahrbares Walzenwechselgerüst.The invention is directed to a device for preferably at least in pairs, in particular batchwise, handling and / or transporting back-up rolls and / or work rolls of a roll stand between the arranged in a rolling mill stand and a roll workshop and in the roll workshop, comprising a transverse to the rolling direction of the roll stand from the roll stand in the roll workshop running roll change pit with a locomotive as a moving device for at least a pair or a set of developed support or work rolls and in the roll workshop transverse to the roll change pit and this transverse and movable in or against the rolling direction of the roll stand roll change stand.

Walzgerüste für das Walzen von Stahlbrammen oder Stahlblechen weisen beispielsweise einen aus einem Paar Arbeitswalzen bestehenden Arbeitswalzensatz und jeweils eine oberhalb und eine unterhalb einer Arbeitswalze angeordnete Stützwalze auf. Wenn die Arbeitswalzen und/oder die Stützwalzen verschlissen sind, müssen diese ausgetauscht werden. Hierzu sind verschiedene Einrichtungen bekannt, mittels welcher die aus dem Walzgerüst herausgefahrenen Stützwalzen oder Arbeitswalzen aus der Walzhalle in die Walzenwerkstatt sowie in der Walzenwerkstatt verfahren werden. Ebenso werden mittels solcher Einrichtungen in der Walzenwerkstatt aufgearbeitete Walzensätze wieder dem jeweiligen Walzengerüst als geschliffener Neu-Walzensatz zugeführt.Roll stands for rolling steel slabs or steel sheets include, for example, a work roll set consisting of a pair of work rolls, and one support roll each above and one below a work roll. If the work rolls and / or the backup rolls are worn, they must be replaced. For this purpose, various devices are known, by means of which the retracted from the rolling stand support rollers or work rolls are moved from the rolling hall in the roll workshop and in the roll workshop. Likewise, by means of such devices in the roll workshop refurbished sets of rolls are fed back to the respective roll stand as a ground new set of rolls.

Die JP 52-133061 A offenbart einen zur Durchführung eines "Side Shifting" in einer Walzhalle an einer Walzstraße angeordneten Mechanismus, bei welchem ein jeweils einen neuen und einen alten Satz an Walzen tragendes Gerüst auf einer Verschiebeplattform mittels einer Stange parallel zum Walzengerüst in und gegen die Walzrüstung verschiebbar angeordnet ist. Weiterhin ist ein Wagen über einen gewissen Bereich auf Schienen in einer Richtung quer und senkrecht zur Walzrichtung verfahrbar in der Walzhalle angeordnet. Darüber hinaus offenbart dieses Dokument einen im unmittelbaren Bereich eines Walzgerüstes vertikal anhebbaren und absenkbaren Bodenbereich. Einen ebensolchen Mechanismus für ein "Side Shifting" in einer Walzhalle offenbart die JP 5 192704 A . Ebenso offenbaren die JP 49 014984 B sowie die JP 53 146952 A jeweils eine Vorrichtung für das "Side Shifting" in einer Walzhalle, wobei die JP 53 146952 A ein Walzenwechselgerüst offenbart, welches als Bestandteil eines "Side Shifting"-Mechanismus in einer Walzhalle an einem Walzgerüst angeordnet ist.The JP 52-133061 A discloses a mechanism arranged to perform a "side shifting" in a rolling hall on a rolling line, in which a scaffold carrying respectively a new and an old set of rollers is slidably mounted on a sliding platform by means of a bar parallel to the rolling mill in and against the rolling equipment. Furthermore, a car is transversely over a certain range on rails in one direction arranged perpendicular to the rolling direction movable in the rolling hall. Moreover, this document discloses a vertically raised and lowered floor area in the immediate area of a rolling stand. A similar mechanism for a "side shifting" in a rolling hall reveals the JP 5 192704 A , Likewise reveal the JP 49 014984 B as well as the JP 53 146952 A in each case a device for the "side shifting" in a rolling hall, wherein the JP 53 146952 A discloses a roll change stand, which is arranged as part of a "side shifting" mechanism in a rolling hall on a rolling stand.

Die US 4,510,781 A offenbart in einer Walzhalle in und gegen die Walzrichtung parallel zu dieser verschiebbare Walzenwechselgerüste.The US 4,510,781 A discloses in a rolling hall in and against the rolling direction parallel to this movable roll changing stands.

Eine Einrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus der EP 1 954 416 B1 bekannt. Diese bekannte Einrichtung umfasst eine quer zur Walzrichtung des Walzgerüsts vom Walzengerüst in die Walzenwerkstatt verlaufende Walzenwechselgrube. In dieser Walzenwechselgrube ist eine auf Schienen geführte Verfahreinrichtung in Form einer hydraulisch angetriebenen Lokomotive angeordnet. An diese Lokomotive ist einerseits ein aus dem zugeordneten Walzengerüst ausgebauter Arbeitswalzensatz ankuppelbar und im angekuppelten Zustand aus der Walzhalle in die Walzenwerkstatt und später gewünschtenfalls wieder zurück in die Walzhalle zum Walzengerüst verfahrbar. Andererseits ist an diese Verfahreinrichtung auch ein Stützwalzensatz des Walzgerüstes ankuppelbar und längs der Walzenwechselgrube von der Walzhalle in die Walzenwerkstatt und gewünschtenfalls wieder zurück verfahrbar. Um Gerüstwechselzeiten vermindern zu können, ist aus diesem Dokument darüber hinaus ein in Richtung quer zur Walzenwechseigrube sowie in oder gegen die Walzrichtung des Walzgerüstes verfahrbares Walzenwechselgerüst bekannt, welches mehrere Sätze an Arbeitswalzen aufnehmen kann. Dadurch wird es möglich, an dem jeweiligen Walzengerüst sowohl einen Satz neuer Arbeitswalzen noch während des Betriebes des Walzgerüstes bereitzustellen als auch einen ausgebauten Arbeitswalzensatz unmittelbar nach seinem Ausbau in der Walzenwerkstatt zu parken. Auf dieseA device according to the preamble of claim 1 is known from EP 1 954 416 B1 known. This known device comprises a roll change pit extending transversely to the rolling direction of the roll stand from the roll stand into the roll workshop. In this roll change pit is guided on rails traversing arranged in the form of a hydraulically powered locomotive. On this locomotive on the one hand from the assigned roll stand built-up work roll set can be coupled and moved in the coupled state from the rolling hall in the roll workshop and later, if desired, back into the rolling hall to the rolling stand. On the other hand, a supporting roll set of the rolling stand can be coupled to this traversing device and moved along the roll changing pit from the rolling hall to the rolling mill and, if desired, back again. In order to be able to reduce scaffolding change times, a roll change stand movable in the direction transverse to the roll change pit and in or against the rolling direction of the roll stand is known from this document, which can accommodate a plurality of sets of work rolls. This makes it possible to provide on the respective roll stand both a set of new work rolls still during operation of the rolling stand and to park a developed set of work rolls immediately after its removal in the roll workshop. To this

Weise ist es möglich, die Walzenwechselgrube zunächst für den Ausbau von Arbeitswalzen zu nutzen, dann aber unmittelbar für den Aus- und Einbau eines Stützwalzensatzes zur Verfügung zu stellen.It is possible, first to use the roll change pit for the expansion of work rolls, but then to provide directly for the removal and installation of a support roll set available.

Nachteilig bei diesem Stand der Technik ist es, dass die Stützwalzen ausschließlich auf den gleichen Fahrbahnen, nämlich denen der Walzenwechselgrube, ein- und ausgefahren werden. Dies bedeutet, dass eine aus dem Walzgerüst herausgefahrene Stützwalze oder ein aus dem Walzengerüst herausgefahrener Stützwalzensatz zunächst mit Hilfe einer Hubvorrichtung, beispielsweise eines Hallenkranes, von der Fahrbahn der Verfahreinrichtung entfernt werden muss, damit die Fahrbahn für die Aufnahme neuer Stützwalzen oder eines neuen Stützwalzensatzes vorbereitet ist. Dieses Anheben und Absenken von Stützwalzen oder Stützwalzensätzen während des Stützwalzenwechsels ist arbeits- und zeitintensiv. Dies führt zu längeren Stützwalzenwechselzeiten, was die Produktivität der Walzanlage negativ beeinflusst.A disadvantage of this prior art is that the support rollers only on the same lanes, namely those of the roll change pit, retracted and extended. This means that a rolled-out from the rolling stand support roller or a retracted from the roll stand support roller set must first be removed with the help of a lifting device, such as a hall crane, from the roadway of the shuttle, so that the road is prepared for receiving new support rollers or a new support roller set , This raising and lowering of backup rolls or backup roll sets during the backup roll change is laborious and time consuming. This leads to longer Stützwalzenwechselzeiten, which adversely affects the productivity of the rolling mill.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Lösung zu schaffen, die es ermöglicht, die für einen Stützwalzenwechsel benötigte Zeit zu verringern und den Stützwalzenwechsel zu vereinfachen.The invention is therefore based on the object to provide a solution that makes it possible to reduce the time required for a backup roll change and to simplify the backup roll change.

Bei einer Einrichtung der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass das Walzenwechselgerüst zwei in Walzrichtung des Walzgerüsts beabstandet zueinander angeordnete, querschnittlich insbesondere U-förmig ausgebildete Walzenaufnahmebereiche aufweist, die jeweils sowohl Auflageflächen für die Aufnahme von Arbeitswalzen als auch Auflageflächen für die Aufnahme von Stützwalzen umfassen und die von der in der Walzenwechselgrube verfahrbaren Lokomotive befahrbar sind.In a device of the type described in more detail, this object is achieved in that the roll change stand has two spaced apart in the rolling direction of the rolling stand to each other, in cross-section, in particular U-shaped roll receiving areas, each both bearing surfaces for receiving work rolls and bearing surfaces for the Include recording of support rollers and which are drivable by the movable in the roll changing pit locomotive.

Erfindungsgemäß ist also vorgesehen, dass die Einrichtung zum Handhaben/Hantieren und/oder Transportieren von ausgebauten Stützwalzen und/oder Arbeitswalzen eines Walzgerüstes ein quer zum Walzgerüst und zur Walzenwechselgrube verschiebbares oder verfahrbares Walzenwechselgerüst oder eine Querverschiebeplattform aufweist, so dass dieser Teil der Wechsel-Einrichtung oder diese Walzenwechselvorrichtung nicht nur die Arbeitswalzen, sondern auch oder zusätzlich die Stützwalzen quer verschieben kann. Hierdurch wird eine Reduzierung der Stützwalzenwechselzeiten sowie eine Vereinfachung des Stützwalzenwechsels an Walzgerüsten erreicht.According to the invention, it is thus provided that the device for handling / handling and / or transporting removed support rolls and / or work rolls of a roll stand has a roll change stand which can be displaced or moved transversely to the roll stand and the roll change pit has a transverse displacement platform, so that this part of the changing device or roll changing device can move not only the work rolls, but also or additionally the support rollers transversely. As a result, a reduction of the support roller change times and a simplification of the support roller change is achieved on rolling stands.

In Ausgestaltung sieht die Erfindung vor, dass das Walzenwechselgerüst auf dem Boden einer Grube derart verfahrbar gelagert ist, dass jeweils ein Walzenaufnahmebereich in eine Be- und/oder Verfahrposition zur Walzenwechselgrub- bringbar ist, in welcher die in der Walzenwechselgrube verfahrbar angeordnete Lokomotive in den Walzenaufnahmebereich verfahrbar ist.In an embodiment, the invention provides that the roll changing stand is mounted so movable on the bottom of a pit, that in each case a roll receiving area in a loading and / or Verfahrposition zur Walzenwechselgrub- can be brought, in which the movable in the roll changing pit locomotive in the roll receiving area is movable.

In vorteilhafter Weise zeichnet sich die Erfindung hierbei in Weiterbildung dadurch aus, dass die Walzenaufnahmebereiche derart beabstandet sind, dass in diesen gleichzeitig jeweils ein Paar oder ein Satz übereinander angeordneter Arbeits- und/oder Stützwalzen nebeneinander anordenbar ist. Damit ist es möglich, ein lediglich zwei Walzenaufnahmebereiche aufweisendes Walzenwechselgerüst vorzusehen, in welches dann wahlweise nebeneinander jeweils zwei Sätze Arbeitswalzen oder zwei Sätze Stützwalzen oder aber ein Satz Stützwalzen und ein Satz Arbeitswalzen anordenbar sind. Aufgrund dieser Flexibilität ist es für die Durchführung eines Walzenwechsels ausreichend, ein lediglich zwei Aufnahmebereiche aufweisendes Walzenwechselgerüst oder eine zwei Aufnahmebereiche aufweisende Querverschiebeplattform vorzusehen, was einen überschaubaren Konstruktions- und Investitionsaufwand mit sich bringt. Da sich die Arbeitswalzen und die Stützwalzen in der Regel im Durchmesser unterscheiden, ist es für die Ausbildung einer erfindungsgemäßen Einrichtung zweckmäßig und vorteilhaft, dass die Walzenaufnahmebereiche derart beabstandet sind, dass in diesen gleichzeitig jeweils ein Paar oder Satz übereinander angeordneter Arbeits- und/oder Stützwalzen nebeneinander anordenbar ist.Advantageously, the invention is characterized in a further development characterized in that the roll receiving areas are spaced such that in each case a pair or a set of stacked working and / or support rollers can be arranged side by side. Thus, it is possible to provide a roll change stand having only two roll receiving areas, in which then optionally two sets of work rolls or two sets of support rolls or a set of support rolls and a set of work rolls can be arranged side by side. Due to this flexibility, it is sufficient for the implementation of a roll change to provide only two receiving areas having roll changing stand or a two receiving areas having transverse displacement platform, which brings a manageable design and investment costs. Since the work rolls and the backup rolls generally differ in diameter, it is expedient and advantageous for the formation of a device according to the invention that the roll receiving areas are spaced such that in each case at the same time a pair or set of stacked working and / or support rolls can be arranged next to each other.

Um sowohl Stützwalzen als auch Arbeitswalzen aufnehmen zu können, zeichnet sich die Erfindung weiterhin dadurch aus, dass jeder Walzenaufnahmebereich einen auf dem Arbeitswalzenwechselniveau des Walzgerüsts angeordneten oberen Auflage- oder Verfahrbereich und einen darunter auf dem Stützwalzenwechselniveau des Walzgerüsts und dem Verfahrniveau der Walzenwechselgrube angeordneten unteren Auflage- oder Verfahrbereich aufweist. Mit dieser erfindungsgemäßen Ausgestaltung ist es möglich, beispielsweise auf dem oberen Auflage- oder Verfahrbereich eines Walzenaufnahmebereiches einen Satz Arbeitswalzen zu platzieren und diesen Walzenaufnahmebereich dann in eine Be- und/oder Verfahrposition zur Walzenwechselgrube zu verfahren oder zu verschieben, in welcher Position dann eine Lokomotive diesen Walzenaufnahmebereich befahren kann oder zumindest an den Arbeitswalzensatz ankuppeln kann. Ebenso ist es möglich, auf dem unteren Aufgabe- oder Verfahrbereich einen Stützwalzensatz zu platzieren und diesen Walzenaufnahmebereich in eine Verfahrposition mit der Walzenwechselgrube zu bringen, so dass eine in der Walzenwechselgrube verfahrbare Lokomotive an den Stützwalzensatz ankoppeln und diesen aus dem Walzenwechselgerüst heraus und längs der Walzenwechselgrube zum Walzgerüst ziehen kann. Zu diesem Zwecke ist die in der Walzenwechselgrube verfahrbar angeordnete Lokomotive bei in der Be- oder Verfahrposition befindlichem Walzenaufnahmebereich in den Walzenaufnahmebereich verfahrbar oder an einen darin angeordneten Stütz- oder Arbeitswalzensatz ankoppelbar. Mittels der Lokomotive kann ein jeweiliger Stützwalzen- oder Arbeitswalzensatz oder können Stütz- oder Arbeitswalzen zwischen zugeordnetem Walzgerüst und der Walzenwerkstatt hin und her geschoben werden.In order to accommodate both backup rolls and work rolls, the invention is further characterized in that each roll receiving area a arranged on the working roll change level of the rolling mill upper bearing or Verfahrbereich and arranged underneath on the Stützwalzenwechselniveau of the rolling stand and the Verfahrniveau the roll change pit lower bearing or Verfahrbereich. With this embodiment according to the invention, it is possible, for example, to place a set of work rolls on the upper supporting or moving area of a roll receiving area and then to move or move this roll receiving area into a loading and / or moving position to the roll change pit, in which position then a locomotive Can ride on the roll receiving area or at least can be coupled to the work roll set. It is also possible to place a support roller set on the lower task or travel area and to bring this roller receiving area into a traveling position with the roller changing pit, so that a locomotive movable in the roller changing pit can be coupled to the support roller set and out of the roller changing stand and along the roller changing pit can pull to the rolling stand. For this purpose, the locomotive which is movably arranged in the roll change pit can be moved into the roll receiving area when the roll receiving area is in the moving or moving position or can be coupled to a support or work roll set arranged therein. By means of the locomotive, a respective back-up roll or work roll set or support or work rolls can be pushed back and forth between associated roll stand and the roll shop.

Um die notwendige Querverschiebbarkeit oder Querverfahrbarkeit des Walzenwechselgerüsts zu gewährleisten, ist das Walzenwechselgerüst auf dem Boden einer Grube verfahrbar gelagert ist.In order to ensure the necessary Querverschiebbarkeit or Querverfahrbarkeit the roll changing stand, the roll changing stand is mounted on the floor of a pit movable.

Hierbei ist es, insbesondere um eine Verfahrbarkeit in und aus der Walzenwechselgrube zu ermöglichen, weiterhin zweckmäßig, wenn das Bodenniveau der Grube unterhalb des Bodenniveaus der Walzenwechselgrube ausgebildet ist, was die Erfindung ebenfalls vorsieht. Die ein Verfahren des Walzenwechselgerüsts ermöglichenden Räder können dann unterhalb des Bodenniveaus der Walzenwechselgrube positioniert sein, so dass dabei von der Walzenwechselgrube aus der untere Auflage- oder Verfahrbereich der Walzenaufnahmebereiche dennoch gut zugänglich bleibt.In this case, in particular in order to enable movement into and out of the roll changing pit, it is furthermore expedient if the ground level of the pit is formed below the bottom level of the roll changing pit is what the invention also provides. The wheels that enable a method of the roller changing stand can then be positioned below the floor level of the roller changing pit, so that the lower supporting or moving area of the roller receiving areas still remains easily accessible from the roller changing pit.

Schließlich zeichnet sich die Erfindung dadurch aus, dass die Walzenwechselgrube einen den Stützwalzendurchmesser aufnehmenden Verfahrquerschnitt aufweist. Aufgrund dieser Dimensionierung ist es möglich, in und längs der Walzenwechselgrube einen Stützwalzensatz aus der Walzhalle in die Walzenwerkstatt sowie zurück zu verfahren oder zu verschieben/transportieren.Finally, the invention is characterized in that the roll change pit has a support cross-section receiving the Verfahrquerschnitt. Due to this dimensioning, it is possible to move in and along the roll change pit a support roll set from the rolling hall in the roll workshop and back to move or transport /.

In nicht dargestellter Art und Weise befindet sich in einer Walzhalle eine mindestens ein Walzgerüst aufweisende Walzanlage oder Walzstraße. Dieses mindestens eine Walzgerüst weist einen Satz Arbeitswalzen und einen Satz Stützwalzen auf. Von diesem Walzgerüst geht quer und senkrecht zur Walzrichtung der Walzanlage bzw. des Walzgerüstes eine von der Walzhalle mit dem Walzgerüst in eine Walzenwerkstatt führende Walzenwechselgrube 1 aus, deren walzenwerkstattseitiger Endbereich in Fig. 1 a im Querschnitt dargestellt ist. In der Walzenwechselgrube 1 ist eine hydraulisch bewegte Lokomotive 2 in üblicher Weise längsverschiebbar angeordnet, wobei die Verschiebungsbewegung beispielsweise mittels eines Schub- und Zugzylinders mit angeschlossener Schub- und Zugstange erfolgt. Die Lokomotive 2 weist sowohl ein Kupplungs- oder Ankopplungselement 3 zur Ankopplung der Lokomotive 2 an einen aus dem Walzgerüst heraus geschobenen oder in diesen hinein zu schiebenden Arbeitswalzensatz 4a, 4b als auch weitere Kupplungs- oder Ankopplungselemente 5a, 5b auf, welche an einen aus dem Walzgerüst heraus gefahrenen Stützwalzensatz 6a oder an einen in das Walzgerüst einzufahrenden Stützwalzensatz 6b ankuppelbar sind.In a manner not shown is located in a rolling hall at least one rolling stand having rolling mill or rolling mill. This at least one rolling stand has a set of work rolls and a set of backup rolls. From this rolling stand is transverse and perpendicular to the rolling direction of the rolling mill or the rolling mill a leading from the rolling hall with the rolling mill in a roll workshop roll change pit 1, whose Walzenwerkstattseitiger end in Fig. 1 a is shown in cross-section. In the roll changing pit 1, a hydraulically-moving locomotive 2 is arranged to be longitudinally displaceable in the usual way, wherein the displacement movement takes place, for example, by means of a push and pull cylinder with attached push-pull rod. The locomotive 2 has both a coupling or coupling element 3 for coupling the locomotive 2 to a pushed out of the rolling stand or in this in to sliding work roll set 4a, 4b as well as other coupling or coupling elements 5a, 5b, which can be coupled to a driven out of the rolling stand support roller set 6a or to a retractable into the rolling stand support roller set 6b.

Wie aus dem linken Teilbild der Figur 1a, aber insbesondere aus der Figur 1 ersichtlich ist, ist in der Walzenwerkstatt eine Grube 7 ausgebildet, auf deren Boden ein Walzenwechselgerüst 8 quer zur Walzenwechselgrube 1 und diese querend verfahrbar ist. Hierzu ist das Walzenwechselgerüst 8 unterseitig mit Laufrädern 9 versehen, die auf auf dem Boden der Grube 7 angeordneten Schienen 10 rollen. Auf diesen Schienen 10 ist das Walzenwechselgerüst 8 mit Hilfe einer angekoppelten Zug- und Druckstange 11, die mittels eines Hydraulikzylinders 12 bewegbar ist, verfahrbar. In der Grube 7 ist das Walzenwechselgerüst 8 von einer in Figur 1 dargestellten rechten Position in eine in Figur 2 dargestellte linke Position hin und her und damit sowohl in als auch gegen die Walzrichtung des Walzgerüstes verfahrbar.As from the left part of the picture FIG. 1a but especially from the FIG. 1 it can be seen, a pit 7 is formed in the roll workshop, on the bottom of a roll change stand 8 transverse to the roll change pit 1 and this is transverse traversed. For this purpose, the roll change stand 8 is provided on the underside with wheels 9, which roll on arranged on the bottom of the pit 7 rails 10. On these rails 10, the roll changing stand 8 by means of a coupled pull and push rod 11 which is movable by means of a hydraulic cylinder 12, movable. In the pit 7, the roll changing stand 8 of a in FIG. 1 shown right position in an in FIG. 2 shown left position back and forth and thus movable both in and against the rolling direction of the roll stand.

Das Walzenwechselgerüst 8 weist zwei querschnittlich im Wesentlichen U-förmig ausgebildete Walzenaufnahmebereiche 13, 14 auf, die so weit voneinander beabstandet sind, dass von ihnen sowohl Stützwalzensätze als auch Arbeitswalzensätze zur gleichen Zeit aufgenommen und gehalten werden können. Jeder Walzenaufnahmebereich 13, 14 weist einen auf dem Arbeitswalzenwechselniveau 20 des Walzgerüstes angeordneten oberen Auflage- oder Verfahrbereich 15, 16 auf, der jeweils aus auf gegenüberliegenden Randbereichen des jeweiligen Walzenaufnahmebereiches 13, 14 angeordneten, in Richtung der Walzenwechselgrube 1 ausgerichteten Schienenstränge besteht. Auf diesen Schienensträngen bzw. oberen Auflage- oder Verfahrbereichen 15, 16 sind Arbeitswalzensätze 4a, 4b verfahrbar aufsetzbar. Insofern bilden diese oberen Auflage- oder Verfahrbereiche 15, 16 Auflageflächen für die Aufnahme von Arbeitswalzen oder Arbeitswalzensätzen 4a, 4b. Weiterhin weisen die Walzenaufnahmebereiche 13, 14 unterhalb der oberen Auflage- oder Verfahrbereiche 15, 16 angeordnete und ausgebildete untere Auflage- oder Verfahrbereiche 17, 18 auf, die auf dem Stützwalzenwechselniveau 19 des Walzengerüstes sowie auf Höhe des von diesem Stützwalzenwechselniveau 19 gebildeten Verfahrniveaus der Walzenwechselgrube 1 und damit der darin verfahrenen Lokomotive 2 angeordnet sind. Damit sind die unteren Auflage- oder Verfahrbereiche 17, 18, die Auflageflächen für die Aufnahme von Stützwalzen oder Stützwalzensätzen 6a, 6b ausbilden, in eine Be- und/oder Verfahrposition zur Walzenwechselgrube 1 bringbar, in welcher der jeweils der Walzenwechselgrube 1 zugeordnete Walzenaufnahmebereich 13, 14 von der Lokomotive 2 befahrbar ist, wie dies in Figur 1 dargestellt ist. In dieser dargestellten Position ist die Lokomotive 2 in den im Bild rechten Walzenaufnahmebereich 14 eingefahren und fährt auf diese Weise den über das Kupplungs- oder Ankopplungselement 3 angekoppelten neuen Arbeitswalzensatz 4b von dem Walzenwechselgerüst 8 zu dem Walzgerüst. Wie aus den Figuren 1 und 1a ersichtlich ist, befindet sich das Bodenniveau der Grube 7 unterhalb des Bodenniveaus der Walzenwechselgrube 1. Wie in den weiteren Figuren 3-6 dargestellt ist, sollen in dem Walzenwechselgerüst 8 Stützwalzensätze 6a, 6b handhabbar positioniert werden, die mittels der Lokomotive 2 in jeweils einen der Aufnahmebereiche 13, 14 eingefahren und/oder aus einem der Walzenaufnahmebereiche 13, 14 ausgefahren werden. Zu dem Walzgerüst hin oder von den Walzgerüst weg werden die Stützwalzensätze 6a, 6b in der Walzenwechselgrube 1 ebenso wie die Arbeitswalzensätze 4a, 4b mittels der Lokomotive 2 verfahren, weshalb die Walzenwechselgrube 1 einen den Stützwalzendurchmesser aufnehmenden Verfahrquerschnitt aufweist.The roll changing stand 8 has two cross-sectionally substantially U-shaped roll receiving portions 13, 14, which are spaced so far apart that they can both support roll sets and sets of work rolls are received and held at the same time. Each roller receiving area 13, 14 has an upper supporting or moving area 15, 16 arranged on the working roll change level 20 of the rolling stand, which respectively consists of rail tracks arranged on opposite edge areas of the respective roller receiving area 13, 14 and oriented in the direction of the roll changing pit 1. On these rail tracks or upper support or Verfahrbereichen 15, 16 are working roll sets 4a, 4b placed movable. In this respect, these upper rest or travel areas 15, 16 form support surfaces for receiving work rolls or work roll sets 4a, 4b. Furthermore, the roller receiving areas 13, 14 have lower support or movement areas 17, 18 arranged underneath the upper support or movement areas 15, 16 on, which are arranged on the back-up roll level 19 of the mill stand and at the level of the travel level of the roll change pit 1 formed by this back-up roll level 19, and thus the locomotive 2 moved therein. Thus, the lower support or traversing areas 17, 18, the bearing surfaces for receiving support rollers or backup roller sets 6a, 6b form, in a loading and / or traversing position to the roll change pit 1 can be brought, in which each of the roll change pit 1 associated roll receiving area 13, 14 is drivable by the locomotive 2, as shown in Figure 1. In this illustrated position, the locomotive 2 is moved into the right in the image roller receiving area 14 and moves in this way the coupled via the coupling or coupling element 3 new set of work rolls 4b of the roll changing stand 8 to the rolling stand. Like from the FIGS. 1 and 1a can be seen, the bottom level of the pit 7 is below the bottom level of the roll change pit 1. As in the other Figures 3-6 support roll sets 6a, 6b are to be positioned in the roll changing stand 8, which are retracted by means of the locomotive 2 into respectively one of the receiving areas 13, 14 and / or are extended from one of the roll receiving areas 13, 14. The support roll sets 6a, 6b in the roll change pit 1 as well as the work roll sets 4a, 4b are moved by means of the locomotive 2 to the roll stand or away from the roll stand, for which reason the roll change pit 1 has a travel cross section receiving the support roll diameter.

Die Figur 2 zeigt das Walzenwechselgerüst 8 mit einem in den Walzenaufnahmebereich 14 eingesetzten neuen Stützwalzensatz 6b, der in dieser Position in der Walzenwerkstatt montiert wird. Das Walzenwechselgerüst 8, auch als Wechselplattform oder Querverschiebeplattform bezeichnet, befindet sich in einer Position, in welcher der Walzenaufnahmebereich 14 in fluchtender Deckung zur Walzenwechselgrube 1 positioniert ist, so dass das Walzenwechselgerüst 8 in einer Be- und/oder Verfahrposition zur Walzenwechselgrube 1 positioniert ist. In dieser Position könnte der Stützwalzensatz 6b nun an die Lokomotive angekoppelt und von dieser längs der Walzenwechselgrube 1 zum Walzgerüst gezogen werden. Sollte während der Montage des Stützwalzensatzes 6b ein Arbeitswalzen-Walzenwechsel erforderlich sein, so wird das Walzenwechselgerüst 8 in die in Figur 3 dargestellte Position verschoben. In dieser Position befindet sich der neue Stützwalzensatz 6b nun in einer Warteposition und ist der Walzenaufnahmebereich 13 in einer Be- und/oder Verfahrposition zur Walzenwechselgrube 1 positioniert. Von der Lokomotive 2 wird dann der auszutauschende, alte Arbeitswalzensatz 4a vom Walzgerüst kommend in den Aufnahmebereich 13 bzw. den oberen Auflage- oder Verfahrbereich 15 eingefahren. In dieser Position wird der Arbeitswalzensatz 4a dann vom Hallenkran der Walzenwerkstatt vom Walzenwechselgerüst 8 abgenommen. Außerdem ist es in der in Figur 3 dargestellten Warteposition des neuen Stützwalzensatzes 6b möglich, den auszutauschenden, alten Stützwalzensatz 6a längs der Walzenwechselgrube 1 vom Walzgerüst kommend in den Walzenaufnahmebereich 13 des Walzenwechselgerüstes 8 einzufahren. Nach Positionierung des alten Stützwalzensatzes 6a in dem Walzengerüst 8 wird dieses nun in die in Figur 4 dargestellte Position querverschoben. Nun ist es möglich, den neuen Stützwalzensatz 6b längs der nun mit dem Walzenaufnahmebereich 14 fluchtenden Walzenwechselgrube zum Walzgerüst in die Walzhalle zu verfahren.The FIG. 2 shows the roll changing stand 8 with a new support roll set 6b inserted into the roll receiving area 14, which is mounted in this position in the roll workshop. The roll changing stand 8, also referred to as exchange platform or transverse displacement platform, is in a position in which the roll receiving portion 14 is positioned in alignment with the roll change pit 1 so that the roll change stand 8 is positioned in a loading and / or traversing position to the roll change pit 1. In this position, the support roller set 6b could now be coupled to the locomotive and from this along the roll change pit 1 for Roll stand to be pulled. Should be required during the assembly of the support roller set 6b a work roll roll change, the roll change stand 8 is in the in FIG. 3 moved position shown. In this position, the new support roller set 6b is now in a waiting position and the roller receiving area 13 is positioned in a loading and / or moving position to the roller change pit 1. From the locomotive 2 is then exchanged, old work roll set 4a coming from the mill in the receiving area 13 and the upper support or traversing range 15 retracted. In this position, the work roll set 4a is then removed from the hall crane of the roll workshop from the roll changing stand 8. Besides, it is in the in FIG. 3 shown waiting position of the new support roller set 6b possible to retract the old support roller set to be replaced 6a along the roller change pit 1 coming from the rolling mill in the roll receiving portion 13 of the roll changing stand 8. After positioning the old support roller set 6a in the mill stand 8 this is now in the in FIG. 4 transversely displaced position shown. Now it is possible to move the new support roller set 6b along the now aligned with the roller receiving portion 14 roller change pit to the rolling mill in the rolling hall.

Bei einem Arbeitswalzensatzwechsel wird anschließend, wie dies in Figur 5 dargestellt ist, auf den oberen Auflage- oder Verfahrbereich 16 des Walzenaufnahmebereiches 14 ein neuer Arbeitswalzensatz 4b mit dem Kran abgesetzt. Dieser neue Arbeitswalzensatz 4b wird dann mittels der in Figur 5 nicht dargestellten Lokomotive ebenfalls zum Walzgerüst verschoben und kann dann in das Walzgerüst eingesetzt werden.When a work roll change is then, as in FIG. 5 is shown, on the upper support or Verfahrbereich 16 of the roll receiving portion 14, a new set of work rolls 4b deposited with the crane. This new work roll set 4b is then used by means of the in FIG. 5 not shown locomotive also moved to the rolling stand and can then be used in the mill stand.

Anschließend wird das Walzenwechselgerüst 8 in die in Figur 6 dargestellte Position verfahren, in der es dann möglich ist, den alten Stützwalzensatz 6b in der Walzenwerkstatt zu demontieren. Sollte während der Demontage des Stützwalzensatzes 6b wiederum ein Arbeitswalzen-Walzenwechsel erforderlich sein, wird das Walzenwechselgerüst 8 wiederum querverschoben, so dass dann der Aufnahmebereich 14 mit der Walzenwechselgrube 1 in Be- und/oder Verfahrposition fluchtend zur Deckung gebracht ist. Der dann von der Lokomotive 2 auf den oberen Auflage- oder Verfahrbereich 16 des Walzenaufnahmebereiches 14 verfahrene Arbeitswalzensatz (alter Arbeitswalzensatz 4a) wird mit dem Kran abgehoben. Auf demselben Wege wird mit dem Walzenwerkstatthallenkran danach ein neuer Arbeitswalzensatz 4a auf den oberen Auflage- oder Verfahrbereich 16 des Walzenaufnahmebereiches 14 aufgesetzt, so dass dieser mittels der Lokomotive 2 längs der Walzenwechselgrube 1 zum Walzgerüst verfahren werden kann. Anschließend kann der alte Stützwalzensatz 6b in der in Figur 5 gezeigten Position demontiert werden oder auch wieder in die in Figur 6 dargestellte Position verschoben und dort weiter demontiert werden.Subsequently, the roll changing stand 8 in the in FIG. 6 shown position in which it is then possible to disassemble the old support roller set 6b in the roller workshop. Should a work roll roll change be required again during the disassembly of the support roll set 6b, the roll change stand 8 is in turn moved transversely, so that then the receiving area 14 with the roll change pit 1 in loading and / or Movement position is brought aligned in alignment. The then moved from the locomotive 2 on the upper support or Verfahrbereich 16 of the roller receiving portion 14 set of work rolls (old work set 4a) is lifted with the crane. In the same way with the Walzenwerkstatthallenkran thereafter a new set of work rolls 4a placed on the upper bearing or Verfahrbereich 16 of the roll receiving portion 14 so that it can be moved by means of the locomotive 2 along the roll change pit 1 to the rolling stand. Subsequently, the old support roller set 6b in the in FIG. 5 shown position or again in the in FIG. 6 shifted position shown and further dismantled there.
