Description

Die Erfindung betrifft ein Universal- Walzgerüst mit in zwei parallelen Walzenständern anstellbar gelagerten Horizontal- und Vertikalwalzen.The invention relates to a universal roll stand with adjustable in two parallel roll stands horizontally and vertically mounted rolls.

Mit derartigen, im Durchlauf- oder Reversierbetrieb arbeitenden Universal- Walzgerüsten lassen sich die verschiedensten Profile walzen, z.B. Doppel- T- und U-Träger oder Schienen. Die Horizontal- und Vertikal- Walzensätze dieser Universal-Walzgerüste sind mit Einbaustücken in Fensterausnehmungen der Ständerholme angeordnet, wobei sich die Einbaustücke der Horizontalwalzen paarweise gegen obere und untere Querträger abstützen, die über Druckmuttern von in diese eingreifenden, axial unverschiebbaren, drehbar gelagerten, beiderseits der Walzlinie einander gegenüberstehenden Paaren von Anstellspindeln gehalten werden. Damit zum Walzenwechsel die Querjoche nicht mehr von den übrigen Walzgerüstteilen abgehoben zu werden brauchen, ist bei einer bekannten Universalgerüst- Bauweise das obere Querjoch zweigeteilt, so daß es sich aus- und nach dem Walzenwechsel wieder zurückschwenken und mit dem restlichen Gerüstteil klemmverriegeln läßt. In der ausgeschwenkten Position sind die die Walzen aufnehmenden Einbaustücke frei zugänglich und lassen sich über die Fensterausnehmungen aus dem Gerüst entfernen. Um das Ver- bzw. Ausschwenken zu erreichen, sind bei dieser Bauweise eines Universal- Walzgerüstes neben den einen Walzenwechsel sinnvoll überhaupt erst ermöglichenden Einbaustücken somit außerdem zusätzliche Schwenkmechanismen erforderlich, z.B. in Form von zusätzlichen hydraulischen Schwenkzylindern.With such universal rolling stands operating in continuous or reversing operation, a wide variety of profiles can be rolled, for example double T and U beams or rails. The horizontal and vertical roller sets of these universal roll stands are arranged with chocks in window recesses of the uprights, the chocks of the horizontal rolls being supported in pairs against upper and lower cross members, which are supported by pressure nuts on axially immovable, rotatably mounted, rotating on both sides of the Rolling line opposing pairs of adjusting spindles are held. So that the cross yokes no longer need to be lifted from the other roll stand parts for the roll change, the upper cross yoke is divided into two in a known universal stand construction, so that it can be swung out and back again after the roll change and clamp-locked with the rest of the stand part. In the swiveled-out position, the chocks that hold the rollers are freely accessible and can be removed from the frame via the window recesses. In order to achieve the swiveling or swiveling out, in this construction of a universal roll stand, in addition to the roll change, it makes sense in the first place Installation pieces therefore also require additional swivel mechanisms, for example in the form of additional hydraulic swivel cylinders.

Der Erfindung liegt die Aufgabe zugrunde, ein Universal-Walzgerüst der eingangs genannten Art zu schaffen, das eine einfache Bau- und Betriebsweise erlaubt.The invention has for its object to provide a universal rolling stand of the type mentioned, which allows simple construction and operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die horizontalen Walzen einbaustücklos von in den Walzenständern angeordneten Lagern aufgenommen sind, der von den Antriebselementen abgewandte, bedienungsseitige Walzenständer mit den Lagern in Walzachsrichtung der Horizontalwalzen von dem anderen Walzenständer wegbewegbar ist und die in Kassetten gelagerten Vertikalwalzen in fest mit den Walzenständern verbundenen Führungsrahmen eingeschoben sind. Der Erfindung liegt die grundsätzliche Überlegung zugrunde, daß sich durch das bei Walzgerüsten anderer Art an sich bekannte Verschieben des bedienungsseitigen Walzenständers ein völlig einbaustückloses Universal- Walzgerüst verwirklichen läßt. Denn nach dem Verschieben des bedienungsseitigen Walzenständers liegen nicht nur die Horizontal-, sondern weiterhin auch die Vertikalwalzen frei und sind vom Inneren des auseinandergezogenen Walzgerüstes her zugänglich. Die ansonsten zum Walzenwechsel erforderlichen Einbaustücke, insbesondere die der Vertikalwalzen, können bei der sich aufgrund der Erfindung ergebenden völlig neuen Bauweise eines Universal- Walzgerüstes entfallen, da der mit den Walzenständern fest verbundene Führungsrahmen alle ansonsten von dem Einbaustück einer Vertikalwalze übernommenen Aufgaben erfüllt.This object is achieved according to the invention in that the horizontal rollers are accommodated without assembly from bearings arranged in the roller stands, the operator-side roller stand facing away from the drive elements can be moved away from the other roller stand with the bearings in the rolling axis direction of the horizontal rollers and the vertical rollers stored in cassettes are fixed guide frames connected to the roller stands are inserted. The invention is based on the fundamental consideration that by moving the operator-side roll stand, which is known per se in the case of other types of roll stands, a completely universal roll stand can be implemented without any assembly. After moving the operator-side roll stand, not only the horizontal but also the vertical rolls are exposed and can be accessed from inside the pulled-apart roll stand. The chocks that are otherwise required for changing the rolls, in particular those of the vertical rolls, can be omitted in the completely new construction of a universal roll stand resulting from the invention, since the guide frame which is firmly connected to the roll stands fulfills all the tasks otherwise assumed by the chock of a vertical roll.

Eine die Vertikalwalze tragende Kassette kann somit direkt in die für den Walzbetrieb erforderliche Einbaulage im Walzenständer gebracht werden, nämlich durch Einschieben in den Führungsrahmen, d.h., es bedarf nicht mehr eines Unweges über ein Einbaustück. Die Führungsrahmen weisen daher vorteilhaft von innen her durch die Walzenständer zugängliche Kassettenausnehmungen auf, z.B. in Form von das Einschieben erleichternden Gleitführungen.A cassette carrying the vertical roller can thus be brought directly into the installation position in the roller stand required for the rolling operation, namely by inserting it into the guide frame, that is, it is no longer necessary to travel through an installation piece. The guide frames therefore advantageously point from cassette recesses accessible from the inside through the roller stands, for example in the form of sliding guides that facilitate insertion.

Es wird vorgeschlagen, daß die Führungsrahmen über Zuganker fest mit den Walzenständern verbunden sind. Zwar ließen sich die Führungsrahmen auch einstückig mit den Walzenständern als Gußteil erstellen, jedoch bietet eine mehrteilige Bauweise herstellungstechnische Vorteile, die insbesondere ein preiswertes Ausbrennen von Walzenständer und Führungsrahmen aus einer Bramme und damit eine einfache Stahlkonstrukion erlaubt. Die über die Verspannung, mittels zwei oder vier Zugankern, zu erreichende feste Verbindung ist so, daß der nach seinem Anbau horizontal liegende Führungsrahmen in der Lage ist, die auftretenden Walzkräfte aufzunehmen.It is proposed that the guide frames are firmly connected to the roller stands via tie rods. Although the guide frames could also be made in one piece with the roller stands as a cast part, a multi-part construction offers advantages in terms of production technology, which in particular allows inexpensive burning out of the roller stands and guide frames from a slab and thus a simple steel construction. The fixed connection to be achieved via the bracing, by means of two or four tie rods, is such that the guide frame lying horizontally after its attachment is able to absorb the rolling forces that occur.

Nach einem Vorschlag der Erfindung sind die Führungsrahmen zweiteilig und bestehen aus einem Kassettenträgerteil mit einem außen aufgesetzten Querhaupt. Beim Anbau des Führungsrahmens werden das Querhaupt und das Kassettenträgerteil über die Zuganker an dem Walzenständer festgelegt. Die zweiteilige Bauweise des Führungsrahmens bietet den Vorteil, daß sich die Vertikalwalzen- Anstellsysteme in den Querhäuptern anordnen lassen.According to a proposal of the invention, the guide frames are in two parts and consist of a cassette support part with an externally placed crosshead. When the guide frame is attached, the crosshead and the cassette support part are fixed to the roller stand via the tie rods. The two-part construction of the guide frame offers the advantage that the vertical roller adjustment systems can be arranged in the crossheads.

Zum Betrieb des erfindungsgemäßen Universal- Walzgerüstes das auch als Wechselgerüst bereitgestellt werden könnte, als Durchlaufgerüst empfiehlt sich ein Vertikalwalzen-Anstellsystem, das aus einer Keilanstellung und von dieser gegen die Kassette beaufschlagten Beilagen besteht. Das im Konti- bzw. Durchlaufbetrieb arbeitende Universal- Walzgerüst erhält somit eine einmalige Anstellung, wozu die Beilagen von hinten, im Stegbereich an die Kassette angebracht werden. Die Beilagen gleichen das Abdrehmaß der Vertikalwalzen aus und ermöglichen eine Einstellung des Walzspaltes an verschieden breite Profile.For the operation of the universal roll stand according to the invention, which could also be provided as an interchangeable stand, a vertical roll adjustment system is recommended as a pass-through stand, which consists of a wedge adjustment and inserts loaded by it against the cassette. The universal rolling stand, which works in continuous or continuous operation, is thus given a one-off job, for which the inserts are attached to the cassette from behind in the web area. The inserts compensate for the degree of twisting of the vertical rolls and allow the roll gap to be adjusted to profiles of different widths.

Hingegen dient die Keilanstellung zur Feineinstellung, beispielsweise mit einem Verstellweg von +/- 5 mm, so daß sich der Walzenverschleiß und eine Auffederung des Universal-Walzgerüstes korrigieren lassen.The wedge adjustment, on the other hand, is used for fine adjustment, for example with an adjustment path of +/- 5 mm, so that the wear on the rollers and the spring deflection of the universal roll stand can be corrected.

Die einfache Bauweise des Universal- Walzgerüstes läßt sich unterstützen, indem alle Anstellungen von Hand, z.B. mit einer auf dem Verstellkeil aufgesetzten Ratsche, durchgeführt werden; gleichwohl eignen sich z.B. auch Hydro- oder Elektromotoren. Dies vor allem dann, wenn das Universal- Walzgerüst im Reversierbetrieb arbeitet. In diesem Fall ließe sich zwischen dem Querhaupt und der Kassette, dort wo bei der mechanischen Keilanstellung die Beilagen angeordnet sind, ein Hydraulikzylinder einsetzen; es könnte auch das ganze Querhaupt gegen das Kassettenträgerteil und damit die Kassette mit der Vertikalwalze anstellbar sein, beispielsweise in Form von zwei in mechanisch miteinander synchronisierten, angetriebenen Anstellmuttern angeordneten Anstellspindeln.The simple design of the universal roll stand can be supported by all manual adjustments, e.g. be carried out with a ratchet placed on the adjustment wedge; nevertheless, e.g. also hydraulic or electric motors. This is especially true when the universal roll stand is operating in reverse operation. In this case, a hydraulic cylinder could be inserted between the crosshead and the cassette, where the shims are arranged for the mechanical wedge adjustment; it could also be possible to position the entire crosshead against the cassette carrier part and thus the cassette with the vertical roller, for example in the form of two adjusting spindles arranged in mechanically synchronized, driven adjusting nuts.

Wenn zwischen den Kassetten und den Walzen- Anstellsystemen vorteilhaft ein U-förmiges Abstützteil angeordnet ist, läßt sich nach hinten hin, d.h. an der von dem Walzspalt bzw. der Walzlinie abgewandten Seite eine gute Abstützung für die Vertikalwalzkräfte erreichen, nämlich über den eine große Auf- bzw. Anlagefläche bietenden stegförmigen Abschnitt des U-förmigen Abstützteils. Die Kassette selbst und damit das in den Führungsrahmen hineinzuschiebende und daraus herauszuziehende Wechselteil besteht nämlich lediglich aus einer Ober- und einer Unterplatte sowie einer in den Platten befestigten Tragachse mit Lager für die Vertikalwalze.If a U-shaped supporting part is advantageously arranged between the cassettes and the roller adjustment systems, it can be moved towards the rear, i.e. achieve good support for the vertical rolling forces on the side facing away from the roll gap or the rolling line, namely via the web-shaped section of the U-shaped support part which offers a large contact surface. The cassette itself and thus the interchangeable part to be pushed into and removed from the guide frame only consists of an upper and a lower plate as well as a support shaft fastened in the plates with bearings for the vertical roller.

Das erfindungsgemäße Universal- Walzgerüst läßt sich mit einteiligen Horizontalwalzen betreiben. Wenn jedoch alternativ mehrteilige, über einen Zuganker zu einer Einheit verspannte Horizontalwalzen eingesetzt werden, läßt sich die einfache und wirtschaftliche Bauweise des erfindungsgemäßen Universal-Walzgerüstes weiter fördern, denn bei verschlissenem Walzkörper braucht nicht mehr die gesamte Horizontalwalze, sondern lediglich der Walzring ausgetauscht zu werden.The universal roll stand according to the invention can be operated with one-piece horizontal rolls. However, if, as an alternative, multi-part horizontal rollers braced via a tie rod to form a unit are used, the simple and Promote the economical construction of the universal roll stand according to the invention, because if the roll body is worn out, it is no longer necessary to replace the entire horizontal roll, but only the roll ring.

Gemäß einer Ausgestaltung sind die Horizontalwalzen in von einem Schneckengetriebe verstellbaren Exzentern angeordnet. Mittels des die Exzenter verdrehenden Schneckengetriebes lassen sich die Horizontalwalzen auf das gewüschte Anstellmaß einstellen.According to one embodiment, the horizontal rollers are arranged in eccentrics that are adjustable by a worm gear. The horizontal rollers can be adjusted to the desired pitch by means of the worm gear rotating the eccentric.

Wenn die Kassetten an ihren dem Walzspalt zugewandten, innenliegenden Seiten mit einer brillenartigen, von den ein- und auslaufseitigen Walzgut- Seitenführungen beaufschlagten Einfassung versehen sind, läßt sich mit Hilfe der Seitenfühurungen gleichzeitig - über die Einfassung (brillenartige Umrahmung) - auch die Kassette, z.B. hydraulisch nach hinten, gegen das Anstellsystem drücken und damit eine Ausbalancierung erreichen.If the cassettes on their inner sides facing the roll gap are provided with an eyeglass-like bezel which is loaded by the side guides of the rolling stock on the inlet and outlet side, the cassette, e.g. the bezel, can also be used at the same time with the help of the side guides. Hydraulically backwards, press against the adjustment system and thus achieve a balance.

Wie in Figur 1 dargestellt, besitzt ein Universal- Walzgerüst 1 einen antriebseitigen, mit einer Fundament- Sohlplatte 2 verbundenen Walzenständer 3 und einen beweglichen, bedienungsseitigen Walzenständer 4. Die Walzenständer 3,4 sind parallel zueinander angeordnet und zum Wegbewegen bzw. -fahren greift an den bedienungsseitigen Walzenständer 4 ein Verstellzylinder 5 mit seiner Kolbenstange 6 an. Die von dem Walzenständer 3 weggefahrene Position des bedienungsseitigen Walzenständers 4 ist in Figur 1 strichpunktiert dargestellt (vergleiche den dort mit 4' bezifferten Walzenständer). In den Walzenständern 3,4 sind - einbaustücklos - eine obere und eine untere Horizontalwalze 7,8 sowie zwei Vertikalwalzen 9 angeordnet.As shown in FIG. 1, a universal roll stand 1 has a drive stand 3 connected to a base plate 2 and a movable stand 4 on the operator side. The roll stands 3, 4 are arranged parallel to one another and act to move or drive away the operator-side roll stand 4 an adjusting cylinder 5 with its piston rod 6. The position of the operator-side roller stand 4 moved away from the roller stand 3 is shown in dash-dot lines in FIG. 1 (compare the roller stand numbered 4 'there). In the roll stands 3, 4, an upper and a lower horizontal roll 7, 8 and two vertical rolls 9 are arranged - without any installation parts.

Die Horizontalwalzen 7,8 sind mehrteilig ausgebildet (vergleiche die obere Hälfte von Figur 1) und bestehen aus zwei Tragwellen 11,12, von denen die eine in dem antriebsseitigen Walzenständer 3 und die andere in dem bedienungsseitigen Walzenständer 4 über Lager 13 gelagert ist; sie schließen zwischen sich einen Walzring 14 ein und sind durch einen von der Bedienungsseite her durch die Tragwelle 12 gesteckten, bis zur Tragwelle 11 reichenden Zuganker 15 miteinander zu einer Einheit verspannt. Die Lager 13 der Horizontalwalzen 7,8 befinden sich unmittelbar in den Walzenständern 3,4; sie werden dort allerdings von Exzenterhülsen 16 umschlossen, die in einer Gleitbuchse 17 angeordnet sind; außerdem sind die Exzenter 17 mit einem Schneckenrad 18 versehen, das mit einer Schneckenwelle 19 kämmt, die von Hand betrieben wird. Die Schneckengetriebe 21 (Schneckenrad 18 und Schneckenwelle 19) für die obere und die untere Horizontalwalze 7,8 sind durch eine gemeinsame Gelenkwelle 22 und die Schneckengetriebe 21 der oberen Horizontalwalze sond vom Antriebs- zum bedienungsseitigen Ständer 3,4 durch eine Gelenkwelle 22 A miteinander verbunden und damit mechanisch synchronisiert (vergleiche Figur 2 und 3). Zum Anstellen der Horizontalwalzen 7,8 bzw. der Walzringe 14 überträgt sich die Drehbewegung der Schneckenwellen 19 über die Schneckenräder 18 und die Exzenter 16 auf die Tragwellen 11,12 der mehrteiligen Horizontalwalzen 7,8, die sich - je nach Drehrichtung des Schneckengetriebes 21, - entweder voneinander entfernen oder einander nähern.The horizontal rollers 7, 8 are formed in several parts (compare the upper half of FIG. 1) and consist of two support shafts 11, 12, one of which is mounted in the drive-side roller stand 3 and the other in the operator-side roller stand 4 via bearings 13; they enclose a rolling ring 14 between them and are clamped together to form a unit by a tie rod 15 which is inserted from the operating side through the support shaft 12 and extends to the support shaft 11. The bearings 13 of the horizontal rollers 7, 8 are located directly in the roller stands 3, 4; however, they are enclosed there by eccentric sleeves 16, which are arranged in a sliding bush 17; in addition, the eccentrics 17 are provided with a worm wheel 18 which meshes with a worm shaft 19 which is operated by hand. The worm gear 21 (worm wheel 18 and worm shaft 19) for the upper and the lower horizontal roller 7, 8 are connected to one another by a common propeller shaft 22 and the worm gear 21 of the upper horizontal roller from the drive stand to the operator-side stand 3, 4 by means of a propeller shaft 22 A. and thus mechanically synchronized (see Figures 2 and 3). To turn the horizontal rollers 7, 8 or the rolling rings 14, the rotary movement of the worm shafts 19 is transmitted via the Worm gears 18 and the eccentrics 16 on the support shafts 11, 12 of the multi-part horizontal rollers 7, 8 which, depending on the direction of rotation of the worm gear 21, either move away from one another or approach one another.

Wie die Horizontalwalzen 7,8, so sind auch die Vertikalwalzen 9 einbaustücklos in den Walzenständern 3,4 angeordnet, und zwar in horizontalen seitlichen Führungsrahmen 23. Diese sind zweiteilig ausgebildet und bestehen aus einem Kassettenträger- teil 24 und einem darauf von außen aufgesetzten Querhaupt 25 (vergleiche Figur 3). Der Führungsrahmen 23, d.h. das Kassettenträgerteil 24 und das Querhaupt 25 sind über vier Zuganker 26 (vergleiche Figur 4) so fest mit den Walzenständern 3,4 verspannt, daß sie die im Walzbetrieb auftretenden Vertikal- Walzkräfte aufnehmen können. Die Führungsrahmen 23 sind mit einer Kassettenausnehmung 27 versehen, in die sich - nach dem Auseinanderfahren der Walzenständer 3,4 in die in Figur 1 strichpunktiert dargestellte Position des Walzenständers 4' - eine auf einer Tragachse 28 eine Vertikalwalze 9 aufnehmende, aus einer oberen und einer unteren Platte bestehende Kassette 29 durch den Walzenständer 3 bzw. 4 von innen her einschieben läßt. Der Kassette 29 ist ein U-förmiges Abstützteil 30 zugeordnet, das mit seinem Steg nach außen zum Querhaupt 25 hin weisend in die Kassettenausnehmung 27 eingeschoben wird, so daß dem Querhaupt 25 des Führungsrahmens 23 eine große Auflagefläche der Kassette 29, nämlich mittelbar über das Abstützteil 30 zugewandt ist. Im Querhaupt 25 ist das Vertikalwalzen- Anstellsystem 31 angeordnet, das in Form einer Keilanstellung 32 ausgebildet ist, bei der der Verstellkeil über eine Gewindespindel 33 von Hand verstellbar ist. Die der Feineinstellung dienende Keilanstellung 32 übt über zwischen dem Querhaupt 25 und der Kassette 29 eingesetzte, an dem Abstützteil 30 befestigte Beilagen 34 - diese dienen der Grobanstellung - eine Anstellkraft auf die Kassette 29 und damit die Vertikalwalze 9 aus.Like the horizontal rollers 7, 8, the vertical rollers 9 are also arranged in the roller stands 3, 4 without any installation parts, specifically in horizontal lateral guide frames 23. These are formed in two parts and consist of a cassette carrier part 24 and a crosshead 25 placed thereon from the outside (see Figure 3). The guide frame 23, ie the cassette carrier part 24 and the crosshead 25 are so tightly clamped to the roller stands 3, 4 via four tie rods 26 (see FIG. 4) that they can absorb the vertical rolling forces occurring in the rolling operation. The guide frames 23 are provided with a cassette recess 27, into which - after the roller stands 3, 4 have moved apart into the position of the roller stand 4 'shown in dash-dotted lines in FIG. 1 - a vertical roller 9 accommodating a supporting axis 28, consisting of an upper and an upper one lower plate existing cassette 29 can be inserted through the roller stand 3 or 4 from the inside. The cassette 29 is assigned a U-shaped support part 30, which is inserted with its web pointing outwards towards the crosshead 25 into the cassette recess 27, so that the crosshead 25 of the guide frame 23 has a large contact surface of the cassette 29, namely indirectly via the support part 30 is facing. In the crosshead 25, the vertical roller adjustment system 31 is arranged, which is designed in the form of a wedge adjustment 32, in which the adjustment wedge is manually adjustable via a threaded spindle 33. The wedge adjustment 32, which is used for fine adjustment, exerts an adjusting force on the cassette 29 and thus the vertical roller 9 via inserts 34 inserted between the crosshead 25 and the cassette 29 and fastened to the supporting part 30.

An ihren dem Walzspalt bzw. der Walzlinie 35 zugewandten, innenliegenden Seiten sind die Kassetten 29 mit einer brillenartigen Einfassung 36 versehen, die von den Walzgut-Seitenführungen 37, die sich gegen die Einfassungen 36 legen, nach außen, d.h. in Richtung auf das Walzenanstellsystem 31 hin beaufschlagt werden; sie balancieren somit die Vertikalwalzen 9 bzw. die Kassetten 29 aus. Die die Kassetten 39 nach hinten hin andrückende Kraft wird durch die die Walzgut- Seitenführungen 37 verstellenden Zylinder 38 aufgebracht.On their inner sides facing the roll gap or the rolling line 35, the cassettes 29 are provided with an eyeglass-like bezel 36 which extends outwards from the rolling stock side guides 37, which lie against the bezels 36. in the direction of the roller adjustment system 31; they thus balance the vertical rollers 9 or the cassettes 29. The force pressing the cassettes 39 towards the rear is applied by the cylinders 38 which adjust the rolling material side guides 37.

Zum Walzenwechsel werden die die beiden Walzenständer 3,4 des Universal- Walzgerüstes 1 miteinander verbindenden Zuganker 39 gelöst und die die Horizontalwalzen 7,8 miteinander verspannenden Zuganker 15 gelöst. Danach verfährt der Verstellzylinder 5 den bedienungsseitigen Walzenständer 4 von dem Walzenständer 3 weg in die in Figur 1 strichpunktiert dargestellte Position. Die Tragwellen 12, die Lager 13 sowie die Exzenterbüchsen 16 nebst Schneckenantrieb 21 (Schneckenwelle 19 und Schneckenrad 18) bleiben dabei in ihrer festen Einbaulage. Nach dem Auseinanderfahren sind sowohl die Walzringe 14 der Horizontalwalzen 7,8 als auch die Kassetten 29 mit den Vertikalwalzen 9 von innen her frei zugänglich. Mittels z.B. des in dem Walzwerk vorhandenen Hallenkranes und einer geeigneten Greifvorrichtung lassen sich sodann die Walzringe 14 und/oder die Kassetten 29 mit den Vertikalwalzen 9 aus ihrer Einbaulage auf den Tragwellen 12 bzw. im Kassettenträgerteil 24 der Führungsrahmen 23 entfernen und durch neubestückte Kassetten bzw. neue Walzringe ersetzen. Sobald der bedienungsseitige Walzenständer 4 wieder in seine Betriebsposition zurückgefahren und mit dem gegenüberliegenden Walzenständer verbunden ist sowie die Zuganker und die Tragwellen 11,12 der Horizontalwalzen 7,8 vorgespannt sind, ist das Universal- Walzgerüst 1 zum erneuten Einsatz bereit.To change the rolls, the tie rods 39 connecting the two roll stands 3, 4 of the universal roll stand 1 are released and the tie rods 15 bracing the horizontal rolls 7, 8 are released. The adjusting cylinder 5 then moves the roller stand 4 on the operator side away from the roller stand 3 into the position shown in broken lines in FIG. The support shafts 12, the bearings 13 and the eccentric bushes 16 together with worm drive 21 (worm shaft 19 and worm wheel 18) remain in their fixed installation position. After moving apart, both the roller rings 14 of the horizontal rollers 7, 8 and the cassettes 29 with the vertical rollers 9 are freely accessible from the inside. With e.g. of the hall crane present in the rolling mill and a suitable gripping device, the rolling rings 14 and / or the cassettes 29 with the vertical rolls 9 can then be removed from their installation position on the supporting shafts 12 or in the cassette carrier part 24 of the guide frame 23 and by newly fitted cassettes or new rolling rings replace. As soon as the operator-side roll stand 4 is moved back into its operating position and is connected to the opposite roll stand and the tie rods and the support shafts 11, 12 of the horizontal rolls 7, 8 are pretensioned, the universal roll stand 1 is ready for use again.
