Description

Die Erfindung betrifft eine Walzanlage zum Walzen metallischen Guts, die mindestens ein Walzgerüst aufweist sowie eine sich beiderseits des Walzgerüsts über eine vorgegebene Länge erstreckende Förderstrecke für das zu walzende Gut.The invention relates to a rolling mill for rolling metallic Guts having at least one rolling mill and a both sides of the rolling stand over a predetermined length extending conveyor line for the material to be rolled.

Walzanlagen der gattungsgemäßen Art werden beispielsweise für die Herstellung von Aluminiumblech benötigt. Dabei wird das Blech in einem mehrstufigen Prozess hergestellt, bei dem zunächst ein Warmwalzen der Bramme erfolgt. Ist diese hinreichend ausgewalzt und ggf. wärmebehandelt, erfolgt ein Kaltwalzen des Blechs auf die Enddicke. Sowohl Warmwalzanlagen als auch Kaltwalzanlagen sind für diesen Zweck gebräuchlich und im Stand der Technik hinlänglich beschrieben.Rolling plants of the generic type are required for example for the production of aluminum sheet. In this case, the sheet is produced in a multi-stage process in which initially takes place a hot rolling of the slab. If this is sufficiently rolled out and if necessary heat-treated, the sheet is cold-rolled to the final thickness. Both hot rolling and cold rolling are common for this purpose and described adequately in the prior art.

Die WO 98/53111 offenbart ein Verfahren zur Erzeugung von warmgewalztem Aluminium-Dosenband, wobei das Verfahren insbesondere für geringere Produktionsmengen von weniger als 250.000 t pro Jahr geeignet sein soll. Dort wird zunächst eine reversierende Vorwalzung des warm eingesetzten Vormaterials auf einer Warmwalzanlage vorgesehen, woran sich unmittelbar ein Fertigwalzen des Bandes anschließt, der eine Wärmebehandlung des zu Bunden aufgehaspelten Bandes folgt. Dabei wird während der letzten Fertigwalzstiche die Rekristallisation im Walzgut durch gesteuerte Temperaturführung des Warmbandes unterdrückt und die Rekristallisation erst im unmittelbaren Anschluss an die Fertigwalzung außerhalb der Walzstrasse gezielt herbeigefügt.The WO 98/53111 discloses a method of producing hot rolled aluminum can band, which method is particularly suitable for lower production quantities of less than 250,000 t per year. There, a reversing roughing of the hot starting material is first provided on a hot rolling mill, which is followed immediately by a finish rolling of the strip, which is followed by a heat treatment of the band wound up into coils. In this case, the recrystallization in the rolling stock is suppressed by controlled temperature control of the hot strip during the last finish rolling passes and the recrystallization brought about specifically in the immediate aftermath of the finish rolling outside the rolling train.

Auch die WO 96/10655 und die WO 96/10656 betreffen ein Fertigungsverfahren für Aluminiumblech. Auch hier erfolgt zunächst ein Warmwalzen der Bramme bzw. des durch den Walzprozess hergestellten Bandes auf einer Warmwalzanlage. Dann wird ein Wärmebehandlungsprozess vorgenommen und schließlich ein Kaltwalzvorgang auf einer Kaltwalzanlage durchgeführt.Also the WO 96/10655 and the WO 96/10656 relate to a manufacturing process for aluminum sheet. Again, there is first a hot rolling of the slab or the strip produced by the rolling process on a hot rolling mill. Then, a heat treatment process is performed, and finally, a cold rolling operation is performed on a cold rolling mill.

Die Warmwalzanlage und die Kaltwalzanlage unterscheiden sich dabei grundsätzlich, weil die Warmwalzanlage beiderseits des Walzgerüsts eine sich über eine vorgegebene Länge erstreckende Förderstrecke für das zu walzende Gut benötigt. Die Bramme wird zunächst in die Anlage eingebracht und ausgewalzt. Dabei erfolgt in der Regel ein reversierender Prozess, d. h. die durch das Walzen immer dünner werdende Bramme bewegt sich durch das Walzgerüst hin und her. Nach Abschluss des Warmwalzvorganges wird das ausgewalzte Band auf einem Haspel zu einem Coil bzw. Bund aufgewickelt.The hot rolling mill and the cold rolling mill differ fundamentally because the hot rolling mill on both sides of the roll stand requires a conveying path for the material to be rolled which extends over a predetermined length. The slab is first introduced into the plant and rolled out. As a rule, a reversing process takes place, d. H. the slab, which is getting thinner as a result of rolling, moves back and forth through the mill stand. After completion of the hot rolling process, the rolled strip is wound on a reel to a coil or bundle.

Beim Kaltwalzen wird indes das bereits vorbereitete Coil in die Anlage gebracht. Das Walzgerüst befindet sich zwischen zwei Haspeln. Von dem einen Haspel wird das Band vom Coil abgewickelt und dem Walzspalt zugeführt. Auf der anderen Seite wird das kaltgewalzte Band dem anderen Haspel zugeführt und zum Coil aufgewickelt.During cold rolling, however, the already prepared coil is brought into the system. The rolling stand is located between two reels. From the one reel the tape is unwound from the coil and fed to the nip. On the other side, the cold rolled strip is fed to the other reel and wound up into a coil.

Daher ergeben sich grundsätzlich andere Größenverhältnisse bzw. Bauraumerfordernisse bei einer Warmwalzanlage einerseits und bei der Kaltwalzanlage andererseits. Die Warmwalzanlage benötigt eine große Längenerstreckung, während die Kaltwalzanlage mit relativ geringem Bauraum auskommt.Therefore, in principle, other size ratios or space requirements arise in a hot rolling mill on the one hand and in the cold rolling mill on the other hand. The hot rolling plant requires a large length extension, while the cold rolling plant requires relatively little space.

Mit Blick auf die Auslastung vorhandener Walzanlagen und damit hinsichtlich der Wirtschaftlichkeit der Investitionen ist es nachteilig, dass für die jeweiligen Teilprozesse separate Anlagen benötigt werden. Dies trifft insbesondere dann zu, wenn die Warmwalzanlage während des Kaltwalzens nicht benötigt wird und umgekehrt.With regard to the utilization of existing rolling plants and thus with regard to the economic efficiency of the investments, it is disadvantageous that separate plants are required for the respective sub-processes. This is especially true when the hot rolling mill is not needed during cold rolling and vice versa.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Walzwerk der eingangs genannten Art so auszubilden, dass der genannte Nachteil nicht auftritt und es zu einer rentableren Nutzung kommt.The invention is therefore based on the object, a rolling mill of the type mentioned in such a way that the said disadvantage does not occur and it comes to a more profitable use.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass im Bereich der Längenerstreckung der Förderstrecke mindestens eine Aufnahmevorrichtung für ein Coil des metallischen Guts angeordnet ist, die in einer ersten Position angeordnet werden kann, in der sie das Fördern des metallischen Guts entlang der Förderstrecke nicht behindert, und in einer zweiten Position angeordnet werden kann, in der sie das Coil nahe des Walzgerüsts auf der Förderstrecke zum Ab- bzw. Aufwickeln des Coils positioniert.The solution of this object by the invention is characterized in that in the region of the longitudinal extent of the conveyor path at least one receiving device for a coil of the metallic Guts is arranged, which can be arranged in a first position in which they promote the metallic Guts along the conveyor line not obstructed, and can be arranged in a second position, in which it positions the coil near the roll stand on the conveyor track for winding or winding the coil.

Die Erfindung stellt also darauf ab, dass Maßnahmen ergriffen werden, um eine Warmwalzanlage auch für die Durchführung des Kaltwalzprozesses tauglich zu machen. Die beim Warmwalzen nicht benötigte Aufnahmevorrichtung für ein Coil wird beispielsweise unterhalb des Rollengangs angeordnet, und sie ist während des Warmwalzens nicht im Einsatz. Für das Kaltwalzen wird die Aufnahmevorrichtung in Arbeitsposition gefahren, so dass auf der Warmwalzanlage auch kalt gewalzt werden kann. Die Wirtschaftlichkeit der Walzanlage wird dadurch wesentlich erhöht.The invention thus provides that measures are taken to make a hot rolling mill suitable for carrying out the cold rolling process. The recording device for a coil, which is not required during hot rolling, is arranged below the roller conveyor, for example, and is not used during hot rolling. For cold rolling, the receiving device is moved to working position, so that cold rolling on the hot rolling mill can also be carried out. The efficiency of the rolling mill is thereby substantially increased.

Gemäß einer Weiterbildung ist vorgesehen, dass die mindestens eine Aufnahmevorrichtung auf einer Hubvorrichtung angeordnet ist, mit der sie in vertikale Richtung in gewünschter Höhe positioniert werden kann. Dabei kann insbesondere vorgesehen werden, dass auf der Hubvorrichtung mindestens eine Bandführungsrolle, insbesondere eine angetriebene Bandführungsrolle, angeordnet ist. Diese wird für das Kaltwalzen benötigt, weil das zu walzende Band von dem Haspel in die Horizontale umgelenkt werden muss, bevor das Band dem Walzspalt zugeführt wird. Besonders vorteilhaft ist es dabei, wenn die mindestens eine Bandführungsrolle in der abgesenkten Position der Hubvorrichtung auf Höhe der anderen Rollen der Förderstrecke angeordnet ist. Sie erfüllt damit dann auch während des Warmwalzvorgangs eine Funktion.According to one embodiment, it is provided that the at least one receiving device is arranged on a lifting device, with which it can be positioned in the vertical direction at the desired height. It can be provided in particular that at least one tape guide roller, in particular a driven tape guide roller, is arranged on the lifting device. This is needed for cold rolling because the strip to be rolled must be deflected from the reel to the horizontal before the strip is fed to the nip. It is particularly advantageous if the at least one tape guide roller is arranged in the lowered position of the lifting device at the level of the other rollers of the conveyor line. It then fulfills a function during the hot rolling process.

Mit Vorteil ist ferner eine Warmbesäumschere vorgesehen, die mit Verschiebemitteln, insbesondere Hubmitteln, versehen ist, mit denen sie in Arbeitsposition (für das Warmwalzen) gefahren oder aus dieser herausgefahren werden kann (für das Kaltwalzen).Advantageously, a heat trimming scissors is further provided which is provided with displacement means, in particular lifting means, with which they in working position (for hot rolling) or driven out of this (for cold rolling).

Für das Kaltwalzen vorteilhaft sind ferner Bandstütz- und/oder Bandantriebs- und/oder Bandrichtmittel, die mit Verschiebemitteln, insbesondere Hubmitteln, versehen sind, mit denen sie in Arbeitsposition (für das Kaltwalzen) gefahren oder aus dieser herausgefahren werden können (für das Warmwalzen). Bei den Bandstütz- und/oder Bandantriebs- und/oder Bandrichtmittel handelt es sich bevorzugt um eine an sich vorbekannten Bridlerollenkombination, insbesondere um eine 4-Rollen-Bridlerollenkombination, mit aufgesetztem Treiber.Also advantageous for cold rolling are belt support and / or belt drive and / or belt straightening means which are provided with displacement means, in particular lifting means, with which they can be driven into working position (for cold rolling) or driven out of this (for hot rolling). , The band support and / or band drive and / or band straightening means are preferably a previously known Bridler roller combination, in particular a 4-roller Bridler roller combination, with an attached driver.

Weiterhin kann mindestens eine mit der Bandführungsrolle zusammenwirkende Gegenrolle vorgesehen werden, die in vertikale Richtung verschiebbar ist und in vorgegebener Höhe positioniert werden kann.Furthermore, at least one cooperating with the tape guide roller counter roller can be provided, which is displaceable in the vertical direction and can be positioned at a predetermined height.

Da für das Warmwalzen einerseits und für das Kaltwalzen andererseits unterschiedliche Walzen benötigt werden, sind vorzugsweise Mittel zum Austauschen der Walzen des Walzgerüsts vorgesehen, mit denen der Austausch der Walzen durchgeführt bzw. zumindest unterstützt werden kann.Since different rolls are required for hot rolling on the one hand and for cold rolling on the other hand, means for exchanging the rolls of the roll stand are preferably provided, with which the replacement of the rolls can be carried out or at least supported.

Schließlich sind für die beiden Arten des Walzens unterschiedliche Kühl- bzw. Schmierbedingungen erforderlich. Damit die Walzanlage für beide Walzprozesse eingesetzt werden kann, sieht eine Fortbildung vor, dass die Anlage Mittel zum Versorgen der Walzen des Walzgerüsts und/oder des zu walzenden Guts mit einem Kühl- und/oder Schmiermittel aufweist, wobei diese Mittel wahlweise zur Versorgung mit Walzöl oder zur Versorgung mit Emulsion umschaltbar sind.Finally, different cooling or lubricating conditions are required for the two types of rolling. So that the rolling mill can be used for both rolling processes, a further development provides that the installation has means for supplying the rolls of the rolling stand and / or the material to be rolled with a coolant and / or lubricant, these means optionally for supplying rolling oil or can be switched to supply with emulsion.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.

In the drawing, an embodiment of the invention is shown.
Show it:

Fig. 2
the system according to Fig. 1 during cold rolling of the aluminum strip.

In den Figuren ist eine Walzanlage 1 skizziert, auf der wahlweise ein Kaltwalzprozess oder ein Warmwalzprozess durchgeführt werden kann. Die Walzanlage dient zum Walzen eines metallischen Guts 2, das in Fig. 1 als Bramme und in Fig. 2 als bereits vorgewalztes Blech dargestellt ist. Zum Walzen dient ein Walzgerüst 3, das vorliegend als Quarto-Walzgerüst mit zwei Arbeitswalzen und zwei Stützwalzen ausgebildet ist. Dabei sind die Walzen für das Warmwalzen mit 15 (s. Fig. 1) und die für das Kaltwalzen mit 16 bezeichnet (s. Fig. 2). Genauso können aber auch andere Walzgerüste - eines oder mehrere - zum Einsatz kommen. Beiderseits des Walzgerüsts 3, in den Figuren also links und rechts vom Walzgerüst, erstreckt sich je eine Förderstrecke 4, die eine gewisse Länge L aufweist. Die Längen L sind beiderseits des Walzgerüsts 3 gleich groß, was jedoch nicht zwingend ist. Entlang der Förderstrecke sind eine Anzahl Rollen 9 in bekannter Weise angeordnet.In the figures, a rolling mill 1 is sketched, on which either a cold rolling process or a hot rolling process can be performed. The rolling mill is used for rolling a metallic Guts 2, the in Fig. 1 as a slab and in Fig. 2 is already shown as pre-rolled sheet. For rolling, a roll stand 3 is used, which in the present case is designed as a four-high rolling stand with two work rolls and two back-up rolls. The rolls for hot rolling with 15 (s. Fig. 1 ) and designated for cold rolling 16 (s. Fig. 2 ). In the same way, however, other rolling stands - one or more - can be used. On both sides of the roll stand 3, in the figures so left and right of the roll stand, each extending a conveyor line 4, which has a certain length L. The lengths L are equal on both sides of the roll stand 3, but this is not mandatory. Along the conveyor line a number of rollers 9 are arranged in a known manner.

Mit dem in Fig. 1 dargestellten Aufbau der Anlage 1 wird der Warmwalzprozess vorgenommen. Hierzu bewegt sich die Bramme 2 reversierend (s. horizontalen Doppelpfeil) durch das Walzgerüst 3 hindurch. Bei jedem Walzstich reduziert sich die Dicke der Bramme, bis das für das Warmwalzen gewünschte Dickenmaß erreicht ist.With the in Fig. 1 shown construction of Appendix 1 of the hot rolling process is made. For this purpose, the slab 2 reversibly moves through the rolling stand 3 (see horizontal double arrow). With each pass, the thickness of the slab is reduced until the thickness required for hot rolling is reached.

Unterhalb der Förderstrecke 4, d. h. unterhalb des Rollengangs, ist beiderseits des Walzgerüsts 3 je eine Aufnahmevorrichtung 5 für ein Coil gewalzten Bandes vorgesehen. Nur schematisch ist eine Hubvorrichtung 7 angedeutet sowie ein in Richtung der Vertikalen eingetragener Doppelpfeil. Der ebenfalls eingetragene Hub H deutet an, dass die Hubvorrichtung 7 die Aufnahmevorrichtung 5 samt Coil 6 vertikal anheben oder absenken kann. Hier wie auch in den nachfolgenden Ausführungen ist für ein Bewegungselement schematisch ein Kolben-Zylinder-System skizziert, womit angedeutet werden soll, dass die Bewegung-hydraulisch erfolgen kann. Genauso ist es aber auch möglich, dass die Bewegung durch elektrische Bewegungselemente o. ä. bewerkstelligt werden kann.Below the conveyor line 4, ie below the roller conveyor, a receiving device 5 for a coil rolled strip is provided on both sides of the roll stand 3 each. Only schematically, a lifting device 7 is indicated as well as a registered in the vertical direction double arrow. The also registered stroke H indicates that the lifting device 7, the receiving device 5 together with coil 6 can lift or lower vertically. Here, as well as in the following explanations, a piston-cylinder system is schematically sketched for a movement element, which should indicate that the movement is hydraulic can be done. Equally, however, it is also possible that the movement can be accomplished by means of electrical movement elements or the like.

Beim Warmwalzen gemäß Fig. 1 befindet sich die Aufnahmevorrichtung - mit ausgezogenen Linien dargestellt - in abgesenkter Position; mit gestrichelten Linien ist angedeutet, welche Position die Aufnahmevorrichtung 5 und das Coil 6 während des Kaltwalzens einnimmt. Die Warmwalzposition ist mit A (erste Position) bezeichnet, während die Kaltwalzposition mit B angegeben ist (zweite Position).When hot rolling according to Fig. 1 is the recording device - shown in solid lines - in lowered position; dashed lines indicate which position the receiving device 5 and the coil 6 occupies during cold rolling. The hot rolling position is indicated by A (first position) while the cold rolling position is indicated by B (second position).

Auf der Hubvorrichtung 7 ist weiterhin eine Bandführungsrolle 8 angeordnet, was nur sehr schematisch gezeigt ist. Diese Rolle bewegt sich beim Anheben der Aufnahmevorrichtung 5 für das Coil 6 nach oben bzw. nach unten mit. Dabei ist die Anlage so ausgestaltet, dass die Bandführungsrolle 8 in ihrer abgesenkten Position genau in Höhe der anderen Rollen 9 der Förderstrecke 4 liegt, d. h. sie dient in dieser Position dem Hin- und Herbewegen der Bramme 2. Auch die Bandführungsrolle 8 ist in Fig. 1 mit ausgezogenen Linien in der Position (A) dargestellt, die während des Warmwalzens eingenommen wird, während mit gestrichelten Linien die Position angegeben ist, die während des Kaltwalzens eingenommen wird (Position B).On the lifting device 7, a tape guide roller 8 is further arranged, which is shown only very schematically. This role moves when lifting the receiving device 5 for the coil 6 up or down with. In this case, the system is designed so that the tape guide roller 8 is in its lowered position exactly equal to the other rollers 9 of the conveyor section 4, ie it serves in this position, the reciprocating the slab 2. Also, the tape guide roller 8 is in Fig. 1 with solid lines in the position (A) taken during hot rolling, while dashed lines indicate the position taken during cold rolling (position B).

Für das Warmwalzen wird in der Regel eine Warmbesäumschere 10 benötigt, die an Verschiebemitteln 11 angeordnet ist, mit denen sie vertikal bewegt und in ihre jeweilige Position (A, B) gefahren werden kann. Auch hier gilt, dass die Position A diejenige des Warmwalzens und Position B diejenige des Kaltwalzens bezeichnet. Wie in der Zusammenschau der Figuren 1 und 2 gesehen werden kann, befindet sich die Besäumschere 10 in Fig. 1 beim Warmwalzen in ihrer Arbeitsposition, während sie beim Kaltwalzen außer Eingriff gefahren wurde.For hot rolling a heat trimming shears 10 is usually required, which is arranged on displacement means 11, with which they can be moved vertically and in their respective position (A, B) can be driven. Again, the position A designates that of hot rolling and position B that of cold rolling. As in the synopsis of FIGS. 1 and 2 can be seen, there is the trimming scissors 10 in Fig. 1 during hot rolling in its working position while being driven out of engagement with cold rolling.

Für das Kaltwalzen nicht benötigt werden Bandstütz- und/oder Bandantriebs- und/oder Bandrichtmittel, die mit 12 bezeichnet sind. Es handelt sich dabei insbesondere um eine Bridlerollenkombination mit aufgesetztem Treiber. In Fig. 1, also beim Warmwalzen, befinden sich diese Mittel 12 nicht in ihrer Arbeitsposition, sondern in einem angehobenen Zustand, der durch Verschiebemittel 13 angefahren wird. Entsprechend sind beim Kaltwalzen, s. Fig. 2, diese Mittel 12 über die Verschiebemittel 13 in ihre Arbeitsposition gefahren worden.For the cold rolling not required Bandstütz- and / or tape drive and / or Bandrichtmittel, which are designated by 12. These are in particular a Bridlerollenkombination with attached driver. In Fig. 1 , ie during hot rolling, these means 12 are not in their working position, but in a raised state, which is approached by displacement means 13. Accordingly, during cold rolling, s. Fig. 2 , these means 12 have been moved over the displacement means 13 in their working position.

In Fig. 2 ist eine für das Kaltwalzen benötigte schematisch dargestellte Gegenrolle 14 zu sehen, die durch nicht dargestellte Bewegungsmittel in Arbeitsposition gefahren werden kann. Die Gegenrolle 14 arbeitet mit der Bandführungsrolle 8 zusammen und sorgt für eine Führung und ggf. für einen Antrieb des kaltzuwalzenden Bandes 2.In Fig. 2 is to be seen a counter-roller 14 shown schematically for cold rolling, which can be moved by means not shown moving means in working position. The counter-roller 14 cooperates with the tape guide roller 8 and provides a guide and, if necessary, a drive of the cold-rolled strip 2.

Die beschriebene Walzanlage kann binnen kurzer Zeit (innerhalb einiger Stunden) von der Ausrüstung für das Warmwalzen auf diejenige für das Kaltwalzen und umgekehrt umgerüstet werden. Die Wirtschaftlichkeit der Anlage ist damit im gegebenen Falle, d. h. bei nicht vorliegender Vollauslastung für eine Walzart, erheblich gesteigert.The rolling mill described can be converted within a short time (within a few hours) from the equipment for hot rolling to that for cold rolling and vice versa. The economy of the system is thus in the given case, d. H. in the absence of full utilization for one rolling type, considerably increased.

Eine große Anzahl weiterer Elemente ist zwar nicht dargestellt, jedoch in der Weise, wie es für Warm- bzw. Kaltwalzwerke üblich ist, realisiert. Soweit nachfolgend von neuen Elementen bzw. Bauteilen gesprochen wird, sind hierunter solche zu verstehen, die neu in das Warmwalzwerk integriert werden, um es für das Kaltwalzen tauglich zu machen.Although a large number of other elements is not shown, but in the manner as is customary for hot or cold rolling mills realized. As far as will be discussed below of new elements or components, these are to be understood as those that are newly integrated into the hot rolling mill to make it suitable for cold rolling.

Im Bereich der Auslaufseite ist ein Treibergestell untergebracht sowie eine Postrolle samt Bürstvorrichtung, eine Planheitsmessrolle mit Schutz-Unterzug und Kraftmessdosen und eine Bürstvorrichtung für die Planheitsmessrolle.In the area of the outlet side, a driver frame is housed, as well as a mailing roller with brushing device, a flatness measuring roller with protective underlay and load cells and a brushing device for the flatness measuring roller.

Ferner sind ein Riemenwickler samt Coilzange, ein Überleittisch für den Riemenwickler und ein Dunstabsaugkanal vorhanden.Furthermore, a belt winder including coil tongs, a transfer table for the belt winder and a Dunstabsaugkanal are available.

Zum Spulenhandling ist eine Wegmesssystem für die Spulenpositionierung, ein Wegmesssystem zur Bundpositionierung, ein Wegmesssystem für Niederhalterollen der Bundzange und ein Wegmesssystem für die Bundzange vorgesehen.For coil handling, a path measuring system for coil positioning, a path measuring system for collar positioning, a path measuring system for hold-down rolls of the circlip pliers and a distance measuring system for the collar pliers are provided.

Die Mediensysteme sind, wie schon erwähnt, gegebenenfalls an den wahlweisen Aufbau als Warm- oder Kaltwalzanlage angepasst. Ansonsten sind die Systeme wie an sich bekannt ausgelegt. Dies betrifft die Hydraulik und Pneumatik (Hydraulik- bzw. Pneumatiksteuerungen, Maschinenverrohrung), die Walzölverrohrung im Gerüstbereich, die Emulsionsverrohung im Gerüstbereich, die Öl-Luft-Schmierung (Steuerung der Öl-Luft-Schmierung, Maschinenverrohrung), die zentrale Fettschmierung (Maschinenverrohrung), die Verbindungsrohrleitungen und die Walzölanlage (Walzöl und Emulsion).The media systems are, as already mentioned, optionally adapted to the optional construction as a hot or cold rolling mill. Otherwise, the systems are designed as known per se. This concerns the hydraulics and pneumatics (hydraulic or pneumatic controls, machine piping), the roller oil piping in the framework area, the emulsion agitation in the framework area, the oil-air lubrication (control of the oil-air lubrication, machine piping), the central grease lubrication (machine piping) , the connecting pipes and the rolling oil plant (rolling oil and emulsion).

Zur Vorgehens- und Betriebsweise bzw. zur Umrüstung einer bestehenden Aluminium-Warm-Reversier-Walzanlage zu einer Walzanlage für das kombinierte Warm- und Kaltwalzen sei folgendes angemerkt:For the procedure and mode of operation or for conversion of an existing aluminum hot reversing rolling mill to a rolling mill for the combined hot and cold rolling, the following may be noted:

Die Eingangsbunde werden mit werkseigenen Mitteln auf einen drehbaren Rollenhubwagen zur Bundvorbereitungsstation aufgegeben. Der Rollenhubwagen kann aus dem Schatten des Traggestells der Bundzange herausfahren, um die Bunde (Coils) aufzunehmen. Die Bunde werden vom Rollenhubwagen in die Bundvorbereitungsposition gefahren und dort zur Vorbereitung in die Bundvorbereitungsstation eingefädelt. In der Bundvorbereitungsstation, bestehend aus Bundöffnertischen, Treibrollen-Richteinheit, Schopfschere und Schrottkübel-Verfahreinrichtung, wird der Bandanfang bzw. werden die äußeren Windungen der Bunde abgeschnitten.The entrance bundles are given by factory means on a rotary pallet truck to the federal preparation station. The roller truck can drive out of the shadow of the cradle of the cradle to accommodate the coils. The bundles are moved by the roller truck to the coil preparation position and threaded there for preparation in the federal preparation station. In the bundle preparation station, consisting of opener tables, driving roller straightening unit, cropping shear and scrap bucket traversing device, the beginning of the strip or the outer turns of the bundles are cut off.

Nach dem Vorbereiten werden die Bunde mittels eines drehbaren Rollenhubwagens in die richtige Ablaufposition gedreht und abhängig vom Coildurchmesser höhengerichtet, d. h. auf Haspelhöhe positioniert.After preparing the bundles are rotated by means of a rotatable Rollenhubwagens in the correct drainage position and depending on the coil diameter in height, d. H. positioned at reel height.

Dann werden die Bunde von der vorhandenen Bundzange übernommen und über das Signal der Bundmittenzentrierung und des Wegmesssystems an der Bundzange auf den Abhaspel aufgebracht.Then the bundles are taken over by the existing pliers and applied to the uncoiler via the signal of the center collar centering and the distance measuring system on the pliers.

Um das Anfahren der Bundvorbereitung mit der Bundzange zu ermöglichen, wird das Traggestell zur Bundzange verlängert.In order to make it possible to start the collar preparation with the pliers, the support frame is extended to the collar pliers.

Der Abhaspel 5 wird mit der Hubvorrichtung 7 und entsprechenden Antriebswellen, Axiallager und Bundmittenregelung ausgerüstet.The uncoiler 5 is equipped with the lifting device 7 and corresponding drive shafts, thrust bearing and collar center control.

Sobald das Bund auf dem Haspel aufgebracht wurde, wird die von unten einschwenkbare und angetriebene Andrückrolle (Bandführungsrolle 8) an das Bund angelegt. Die Bundzange wird geöffnet und aus der Walzlinie herausgefahren. Nun kann die zweite Andrückrolle (Gegenrolle 14) an das Bund angelegt werden. Ein Bundöffnermeißel, der am vorhandenen Traggerüst des Treib- bzw. Richtrollenaggregates angeordnet ist, wird zur Führung des Bandanfanges an das Bund gefahren. In abgesenkter Position bilden diese beiden Andrückrollen - wie oben erläutert - einen Bestandteil des Rollgangs für den Warmbetrieb.Once the federal government has been applied to the reel, the pressure roller (belt guide roller 8), which can be pivoted in and driven in from below, is applied to the collar. The pliers are opened and moved out of the rolling line. Now, the second pressure roller (counter roller 14) can be applied to the federal government. A Bundöffnwürißel which is arranged on the existing support frame of the propellant or straightening roller unit is driven to guide the beginning of the tape to the federal government. In lowered position these two pressure rollers - as explained above - form part of the roller table for hot operation.

Der Bandanfang wird durch Drehen des Abhaspels und der angetriebenen Andrückrollen zum Treiber vorgeschoben. Dort wird der Bandanfang über die Kalt-Treibrolle, die Postrolle und die Niederhalterolle gerichtet. Es werden Putzvorrichtungen für die Kalt-Treibrolle und die Postrolle vorgesehen. Die obere Treibrollenlagerung wird mit Kraftmessdosen zur Bandzugmessung ausgestattet. Der Bandanfang wird über eine Schopfschere zur Bridlerollenkombination mit angetriebenen Rollen und dem nachfolgenden Treiber geführt. Die Kombination aus Schopfschere, Bridlerollen und Treiber auf einem gemeinsamen, verfahrbaren Grundrahmen kann über die vorhandene Verfahreinrichtung der Warm-Besäumschere aus bzw. in die Walzlinie eingefahren werden. Der Grundrahmen ist mit einer Ölauffangwanne versehen, die das Walzöl zum Schmieren der Bridlerollen bzw. Bridlerollenlager auffängt und ableitet.The beginning of the tape is fed to the driver by turning the uncoiler and the driven pressure rollers. There, the beginning of the tape is directed over the cold drive roller, the mail roller and the hold-down roller. Cleaning devices are provided for the cold drive roller and the mailing roller. The upper drive roller bearing is equipped with load cells for measuring strip tension. The beginning of the strip is guided via a pair of shear to Bridlerollenkombination with driven rollers and the subsequent driver. The combination of cropping shear, bridle rolls and driver on a common, movable base frame can be moved out of or into the rolling line via the existing moving device of the warming trimming shear. The base frame is provided with an oil sump, which catches and discharges the rolling oil for lubricating the Bridlerollen or Bridlerollenlager.

Der zentrale Gerüstbereich wird aus Gründen der Profil- bzw. Planheitsbeeinflussung mit einer bekannten Walzenverschiebung ausgerüstet. Hierzu werden neben den Modifikationen und Neuteilen zu den Walzensätzen neue Antriebsspindeln mit Spindelbalancierung sowie eine neue Spindelklemmung benötigt.The central frame area is equipped for reasons of profile or flatness influence with a known roll displacement. In addition to the modifications and new parts to the sets of rollers are new Spindles with spindle balancing and a new spindle clamping required.

Die Kühlmittelverteilung erfolgt über die vorhandenen Spritzbalken, die jedoch mit neuen Düsen ausgerüstet werden.The coolant distribution takes place via the existing spray bars, which, however, are equipped with new nozzles.

Für die Kaltwalzstiche wird ein separater Walzensatz erforderlich, der ohne Walzenbürsten, jedoch mit separater Walzenabblasung ausgerüstet ist. Eine weitere Bandabblasung wird in der neu zu fertigenden Einlaufführung (Wasserkasten) angeordnet.For the cold rolling passes a separate set of rolls is required, which is equipped without roller brushes, but with separate Walzenabblasung. Another Bandabblasung is arranged in the newly manufactured inlet guide (water tank).

Der Treiber wird dem vorhandenen Treiber entsprechend baugleich ausgeführt, jedoch zusätzlich mit einer Planheitsmessrolle und zugehöriger Putzvorrichtung ausgestattet. Während des Warmbetriebs wird die Planheitsmessrolle durch einen einschwenkbaren Unterzug geschützt. Es wird eine neue zylindrische Postrolle mit Putzvorrichtung vorgesehen. Die Hydraulikzylinder zur Anstellung der Planheitsmessrolle werden mit Klemmköpfen zur sicheren Positionierung ausgestattet. Die Lageraufnahme der Planheitsmessrolle wird mit Kraftmessdosen zur Bandzugmessung ausgerüstet.The driver is the same design as the existing driver, but also equipped with a flatness measuring roller and associated cleaning device. During warm operation, the flatness measuring roller is protected by a pivoting beam. It will provide a new cylindrical mail role with cleaning device. The hydraulic cylinders for adjusting the flatness measuring roller are equipped with clamping heads for safe positioning. The bearing seat of the flatness measuring roller is equipped with load cells for measuring strip tension.

Im Bereich des vorhandenen Banddickenmessgeräts werden mechanische Befestigungen für den Einbau von Stripscannern angeordnet, die zur Erfassung der Bandkantenposition diesen.In the area of the existing strip thickness gauge mechanical fasteners for the installation of strip scanners are arranged, which for detecting the strip edge position this.

Das aus der Auslaufvorrichtung laufende Band wird über einen hydraulischen heb- und senkbaren Leittisch dem am vorhandenen Traggerüst zum Warm-Gurtumschlinger bzw. Bundzange angeordneten Kalt-Riemenwickler zugeführt. Für den Einbau des neuen Kalt-Riemenwicklers wird das Traggerüst modifiziert.The belt running out of the outlet device is fed by means of a hydraulic lifting and lowering control table to the cold belt winder arranged on the existing support frame for the warm belt wrapper or curb tongs.

Das Zudienen von Spulen erfolgt über die vorhandene Bundzange. Die Spulen werden mit werkseigenen Mitteln auf den Hubstuhl aufgelegt. Der Hubstuhl fährt in eine definierte Höhenposition, von der die Spulen von der vorhandenen Bundzange übernommen werden und über eine Spulenmittenregelung auf den Haspeldom aufgebracht werden. Das Abdienen der Spulen auf der Einlaufseite erfolgt ebenfalls mit der vorhandenen Bundzange. Hier werden die Spulen auf dem vorhandenen Hubstuhl abgelegt und an den vorhandenen Höcker-Kettenförderer übergeben. Die Abdienung der Spulen vom Höcker-Kettenförderer erfolgt mit werkseigenen Mitteln. In beiden Spulenzangen wird die Andrückrolle mit einem Wegmesssystem ausgerüstet.Coils are fed by means of the existing pliers. The bobbins are placed on the lift by factory means. The lift moves to a defined height position, from which the coils of the existing Bundzange be adopted and applied via a Spulenmittenregelung on the reel dome. The delivery of the bobbins on the inlet side also takes place with the existing pliers. Here, the bobbins are placed on the existing lift and transferred to the existing bump chain conveyor. The removal of the bobbins from the hump chain conveyor takes place by means of the factory. In both coil tongs, the pressure roller is equipped with a displacement measuring system.

Die Umrüstung vom Warmwalzbetrieb zum Kaltwalzbetrieb erfolgt wie folgt:The conversion from hot rolling to cold rolling is done as follows:

Zunächst wird der Warm-Arbeitswalzensatz ausgefahren. Dann wird das Walzgerüst manuell mit einem Dampfstahlgerät gereinigt. Anschließend wird der Kalt-Arbeitswalzensatz eingefahren. Weiterhin wird die 4-Rollen-Bridlekombination mit aufgesetztem Treiber in die Anlage eingefahren. Dies geschieht durch Ausfahren der Warm-Besäumschere aus der Walzlinie.First, the hot work roll set is extended. Then the rolling stand is cleaned manually with a steam steel machine. Then the cold work roll set is retracted. Furthermore, the 4-roller Bridlekombination is inserted with attached driver in the system. This is done by extending the warm trimming shear from the rolling line.

Umgekehrt sehen die Maßnahmen für den Wechsel vom Kaltwalzbetrieb zum Warmwalzbetrieb wie folgt aus:Conversely, the measures for the change from cold rolling operation to hot rolling operation are as follows:

Zunächst wird der Kalt-Arbeitswalzensatz ausgefahren. Dann werden die Warm-Arbeitswalzen eingefahren. Anschließend erfolgt das Ausfahren der 4-Rollen-Bridlekombination mit aufgesetztem Treiber aus der Anlage. Dies geschieht durch Einfahren der Warm- Besäumschere in die Walzlinie.First, the cold work roll set is extended. Then the warm work rolls are retracted. The extension of the 4-roller Bridle combination with attached driver is then carried out from the system. This is done by retracting the warm trimming shear into the rolling line.

Ferner werden - wie schon erwähnt - Maßnahmen für den Wechselbetrieb ergriffen, was die Versorgung mit Emulsion bzw. Walzöl anbelangt. Der Abzweig in der vorhandenen Rücklaufleitung für Walzölbetrieb wird mit manuell zu verstellenden Absperrklappen versehen. Die Restentleerung erfolgt in den Pumpensumpf. Im Rücklaufrohr zum ÖI-Rückpumpbehälter wird eine Flammenbox eingebaut. Ein neuer Öl-Rückpumpbehälter wird mit einer separaten Kammer für Spülöl versehen. Weiterhin werden die erforderlichen Rückförderpumpen und Rückpumpleitungen zur Walzölanlage vorgesehen. Neue Walzölvorlaufleitungen mit Umschaltklappen werden so nahe wie möglich an die vorhandenen Grip-Balken angeschlossen. Ein Anschluss für das Ausblasen der Grip-Balken mittels Druckluft ist vorzusehen. Schließlich wird auch ein Anschluss für das Spülen der Spritzbalken mit Walzöl sowie der Gerüstwanne geplant.Furthermore, as already mentioned, measures for alternating operation are taken with regard to the supply of emulsion or rolling oil. The branch in the existing return line for rolling oil operation is provided with manually adjustable shut-off valves. The emptying takes place in the sump. A flame box is installed in the return pipe to the oil return pump container. A new oil return pump container is provided with a separate chamber for flushing oil. Furthermore, the required return pumps and Rückpumpleitungen are provided to the rolling oil plant. New rolling oil supply lines Flaps are connected as close as possible to the existing grip bars. A connection for blowing out the grip beams by means of compressed air is to be provided. Finally, a connection for rinsing the spray bars with rolling oil and the scaffold pan is also planned.

Die Vorgehensweise beim Umschalten von Emulsionsbetrieb auf Walzölbetrieb sieht wie folgt aus:The procedure for switching from emulsion mode to rolling oil mode is as follows:

Zunächst erfolgt ein manuelles Reinigen des Gerüsts mit einem Dampfstrahlgerät. Während dieses Vorgangs wird in den Rückpumpbehälter Emulsion abgeleitet. Dann wird der Grip-Balken mittels Druckluft ausgeblasen. Anschließend wird der Behälter mit Hilfe der Rückförderpumpe bzw. Entleerungspumpe bis zum Minimal-Niveau entleert. Die Armaturen in der Rücklaufleitung für Emulsion werden nach entsprechender Nachtropfzeit geschlossen. Dann wird der Ablauf in die neue Auffangkammer für gebrauchtes Spülöl geöffnet. Nach dem Einschalten der Systempumpe der Walzölanlage wird der Düsenbalken und, falls erforderlich, auch die Gerüstwanne über einen Spülanschluss mit Walzöl gespült. Verunreinigtes Waschöl wird über die Auffangkammer mittels Rückförderpumpen zum Behälter für gebrauchtes Spülöl im neuen Walzölgebäude entsorgt. Schließlich wird der Rücklauf zum Rückpumpenbehälter für Walzöl geöffnet.First, a manual cleaning of the scaffold with a steam jet device. During this process, emulsion is discharged into the return pump tank. Then the grip beam is blown out by means of compressed air. Then the container is emptied to the minimum level with the aid of the return pump or drain pump. The valves in the return line for emulsion are closed after the appropriate dripping time. Then the drain is opened in the new collection chamber for used flushing oil. After switching on the system pump of the rolling oil plant, the nozzle bar and, if necessary, the scaffold pan are also rinsed with rolling oil via a flushing connection. Contaminated wash oil is disposed of via the collecting chamber by means of return pumps to the container for used flushing oil in the new rolling oil building. Finally, the return is opened to the return pump tank for rolling oil.

Die Vorgehensweise beim Umschalten von Walzölbetrieb auf Emulsionsbetrieb erfolgt folgendermaßen:The procedure for switching from rolling oil operation to emulsion operation is as follows:

Der Grip-Balken wird zunächst mittels Druckluft ausgeblasen. Dann wird der Rücklauf zum Rückpumpbehälter für Walzöl nach entsprechender Nachtropfzeit geschlossen. Sodann wird der Restentleerungsanschluss am Rücklauf für Walzöl geöffnet. Nach dem Schließen des Restentleerungsanschlusses am Rücklauf für Walzöl wird der Rücklauf zum Rückpumpbehälter für Emulsion geöffnet.The grip beam is first blown out by means of compressed air. Then the return to the return pump tank for rolling oil is closed after a corresponding dripping time. Then the residual emptying connection at the return for rolling oil is opened. After closing the residual emptying connection at the return for rolling oil, the return to the emulsion return pumping container is opened.

Die Umschattarmaturen in den Rücklaufleitungen sowie die Restentleerungen sind als manuelle Armaturen mit Endlagenüberwachung ausgeführt. Die Umschaltarmaturen in den Vorlaufleitungen am Gerüst sind als pneumatisch betätigte Armaturen mit Endlagenüberwachung ausgebildet.The reversing valves in the return lines as well as the residual emptying are designed as manual valves with end position monitoring. The changeover valves in the flow lines on the scaffold are designed as pneumatically actuated valves with end position monitoring.

Notwendige Modifikationen an der Hydraulik- bzw. der Pneumatiksteuerung sowie zugehörige Änderungen an Pumpen, Kompressoren und dementsprechende Aggregatverrohrung sind nicht näher vermerkt und erfolgen in üblicher fachmännischer Weise.Necessary modifications to the hydraulic or the pneumatic control and associated changes to pumps, compressors and corresponding aggregate piping are not noted and carried out in the usual expert manner.

Die benötigen Änderungen sind sowohl hinsichtlich der apparativen Ausstattung als auch hinsichtlich der zu ergreifenden Maßnahmen relativ preiswert zu bewerkstelligen, so dass ein hoher wirtschaftlicher Nutzen aus dem erfindungsgemäßen Vorschlag zu ziehen ist.The changes that need to be made are relatively inexpensive both in terms of the equipment and in terms of measures to be taken, so that a high economic benefit to draw from the proposal according to the invention.
