Definitions
- the invention relates to a system for hot rolling strip or sheet-shaped rolling stock with two reversing stands arranged directly behind one another between a front and a rear reversing reel.
- a roughing stand and a finishing stand separately are usually used.
- the roller roughness and the roller diameter can thus be adapted to the particular requirements of the shaping process.
- the disadvantage must be accepted that the capacity of the roughing stand is poorly utilized and that on the one hand a large temperature loss is unavoidable due to the conveyance of the rolling stock from the roughing stand to the finishing stand and on the other hand because of the high number of individual passes required in the finishing stand, even if before and Holding furnaces are provided behind the finishing stand.
- the consequence of this is that, particularly in the case of thin hot strips, the required final rolling temperatures can hardly be maintained, especially with higher coil weights.
- the strips to be rolled can only be descaled in one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be prevented.
- a reduction in the strip thickness that can be achieved is accepted because, due to the high temperature losses, the strip temperature that is still permissible is already reached with strip thicknesses of up to approximately 2 mm. It does not need to be explained in more detail that there is also a limited capacity of up to a maximum of 450,000 t / year.
- FR-PS 1 132 772 To avoid high temperature losses, it is already known (FR-PS 1 132 772) to arrange two or three stands immediately one behind the other, so that the rolling stock is rolled in the stands at the same time, which means that fewer passes are necessary.
- a disadvantage of these reversing stands, which are arranged directly one behind the other, is that, due to the similarity of the stands, no adjustment of the roll diameter and the roughness of the rolls to the respective requirements is possible.
- the invention is therefore based on the object to avoid these deficiencies and to improve a system for hot rolling strip or sheet-shaped rolling stock of the type described in such a way that an economical production of thin hot strip with a good surface quality is guaranteed even for medium and high coil weights and the capacity can be increased significantly.
- the invention solves this problem in that a roughing stand is provided directly in front of the front reversing reel and in that the stands can be converted from an optional individual operation to a joint operation.
- the rolling stock is brought to the desired rolling temperature in an oven 1.
- the heated rolling stock is then descaled in a scale washer 2 before it is fed to the roll stands, a roughing stand 3 and two reversing stands 4 serving as finishing stands.
- Two reversing reels 5 and 6 are arranged upstream and downstream of these reversing stands 4, the reversing reels 5 and 6 being able to be equipped either with a heatable mandrel or with a heating hood in order to avoid higher temperature losses.
- the rolled hot strip is then wound on a reel 7.
- a cropping shear 8 is provided between the rear reversing stand 4 and the rear reversing reel 6 for trimming the beginning and ends of the tape.
- the selected arrangement of the cropping shears 8 offers the considerable advantage that both the beginning and the end of the band can be additionally trimmed after the finished stitches.
- the rolling stock is transported in the usual way on roller tables 9, the driven reels 10 of a driver 11 being arranged upstream of the reels 5, 6 and 7.
- the system shown for hot rolling strip or sheet-shaped rolling stock differs from conventional hot rolling systems of a comparable type primarily in that the roughing stand 3 is positioned in front of the two reversing stands 4 serving as finishing stands with the smallest possible distance, so that between the roughing stand 3 and the front reversing stand 4 the reversing reel 5 just finds space.
- This not only makes the usual roller table for receiving the tape for the preliminary stitches unnecessary, but also gives the advantage that all scaffolding can be switched from an individual operation to a common one Operation or a tandem operation can be changed.

Description
Die Erfindung bezieht sich auf eine Anlage zum Warmwalzen von band- oder tafelförmigem Walzgut mit zwei zwischen einem vorderen und einem hinteren Reversierhaspel unmittelbar hintereinander angeordneten Reversiergerüsten.The invention relates to a system for hot rolling strip or sheet-shaped rolling stock with two reversing stands arranged directly behind one another between a front and a rear reversing reel.
Um bei Warmwalzanlagen mitReversiergerüsten die Vor-und Fertigstiche nicht mit denselben Arbeitswalzen durchführen zu müssen, werden üblicherweise ein Vorgerüst und getrennt davon ein Fertiggerüst eingesetzt. Damit kann die Walzenrauhigkeit und der Walzendurchmesser an die jeweiligen Erfordernisse des Verformungsvorganges angepaßt werden. Allerdings muß der Nachteil in Kauf genommen werden, daß die Kapazität des Vorgerüstes schlecht ausgenützt wird und daß einerseits wegen der Förderung des Walzgutes vom Vorgerüst zum Fertiggerüst und anderseits wegen der erforderlichen hohen Anzahl von Einzelstichen beim Fertiggerüst ein großer Temperaturverlust unvermeidbar ist, selbst wenn vor und hinter dem Fertiggerüst Warmhalteöfen vorgesehen sind. Dies hat zur Folge, daß insbesondere bei dünnen Warmbändern die erforderlichen Endwalztemperaturen kaum eingehalten werden können, vor allem bei höheren Bundgewichten. Außerdem können die zu walzenden Bänder nur bei einem oder ganz wenigen Stichen entzundert werden, um höhere Temperaturverluste zu vermeiden. Eine Beeinträchtigung der Qualität der Bandoberfläche ist folglich kaum zu verhindern. Schließlich muß bei solchen Warmwalzanlagen eine Beschränkung der erreichbaren Banddicke nach unten in Kauf genommen werden, weil wegen der hohen Temperaturverluste die noch zulässige Bandtemperatur bereits bei Banddicken bis etwa 2 mm erreicht wird. Daß sich zusätzlich eine begrenzte Kapazität ergibt, die in der Größenordnung biszu maximal 450 000 t/Jahr liegt, braucht wohl nicht näher ausgeführt zu werden.In order to avoid having to carry out the roughing and finishing passes with the same work rolls in hot rolling mills with reversing stands, a roughing stand and a finishing stand separately are usually used. The roller roughness and the roller diameter can thus be adapted to the particular requirements of the shaping process. However, the disadvantage must be accepted that the capacity of the roughing stand is poorly utilized and that on the one hand a large temperature loss is unavoidable due to the conveyance of the rolling stock from the roughing stand to the finishing stand and on the other hand because of the high number of individual passes required in the finishing stand, even if before and Holding furnaces are provided behind the finishing stand. The consequence of this is that, particularly in the case of thin hot strips, the required final rolling temperatures can hardly be maintained, especially with higher coil weights. In addition, the strips to be rolled can only be descaled in one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be prevented. Finally, at such a hot rolling mill, a reduction in the strip thickness that can be achieved is accepted because, due to the high temperature losses, the strip temperature that is still permissible is already reached with strip thicknesses of up to approximately 2 mm. It does not need to be explained in more detail that there is also a limited capacity of up to a maximum of 450,000 t / year.
Zur Vermeidung hoher Temperaturverluste ist es bereits bekannt (FR-PS 1 132 772), zwei oder drei Gerüste unmittelbar hintereinander anzuordnen, so daß das Walzgut in den Gerüsten gleichzeitig gewalzt wird, was entsprechend weniger Durchläufe notwendig macht. Nachteilig bei diesen unmittelbar hintereinander angeordneten Reversiergerüsten ist wiederum, daß durch die Gleichartigkeit der Gerüste keine Anpassung der Walzendurchmesser und der Walzenrauhigkeit an die jeweiligen Erfordernisse möglich ist.To avoid high temperature losses, it is already known (FR-
Der Erfindung liegt somit die Aufgabe zugrunde, diese Mängel zu vermeiden und eine Anlage zum Warmwalzen von band- oder tafelförmigem Walzgut der eingangs geschilderten Art so zu verbessern, daß eine wirtschaftliche Erzeugung von dünnem Warmband mit einer guten Oberflächenqualität auch für mittlere und höhere Bundgewichte gewährleistet und die Kapazität wesentlich gesteigert werden kann.The invention is therefore based on the object to avoid these deficiencies and to improve a system for hot rolling strip or sheet-shaped rolling stock of the type described in such a way that an economical production of thin hot strip with a good surface quality is guaranteed even for medium and high coil weights and the capacity can be increased significantly.
Die Erfindung löst die gestellte Aufgabe dadurch, daß unmittelbar vor dem vorderen Reversierhaspel ein Vorgerüst vorgesehen ist und daß die Gerüste von einem wahlweisen Einzelbetrieb auf einen gemeinsamen Betrieb umstellbar sind.The invention solves this problem in that a roughing stand is provided directly in front of the front reversing reel and in that the stands can be converted from an optional individual operation to a joint operation.
Daß durch das Vorordnen eines Vorgerüstes eine vorteilhafte Anpassung der Arbeitswalzen hinsichtlich ihres Durchmessers und ihrer Oberflächenrauhigkeit an die jeweiligen Verformungserfordernisse möglich ist, ist an sich nicht verwunderlich. Da jedoch im Gegensatz zu der bekannten Anordnung der Vorgerüste das Vorgerüst unmittelbar vor dem vorderen Reversierhaspel vorgesehen wird, entfällt der das Band für die Vorstiche aufnehmende Rollgang zwischen dem Vorgerüst und den Fertiggerüsten. Diese Maßnahme hilft einerseits, den Temperaturverlust des Warmbandes während der Förderung vom Vorgerüst zu den Fertiggerüsten zu vermeiden, und erlaubt anderseits, alle Gerüste gemeinsam einzusetzen. Der Anschluß des Vorgerüstes an die Fertiggerüste bedingt jedoch, daß beim Einzelbetrieb des Vorgerüstes das Warmband durch die offenen Walzspalte der Fertiggerüste hindurchlaufen muß.It is not surprising that the provision of a roughing stand makes it possible to adapt the work rolls advantageously in terms of their diameter and surface roughness to the respective deformation requirements. However, in contrast to the known arrangement of the roughing stands, the roughing stand immediately Before the front reversing reel is provided, the roller table between the roughing stand and the finishing stands, which receives the tape for the preliminary stitches, is omitted. On the one hand, this measure helps to avoid the temperature loss of the hot strip during the conveying from the roughing stand to the finishing stands, and on the other hand it allows all the stands to be used together. However, the connection of the roughing stand to the finishing stands means that when the roughing stand is operated individually, the hot strip must run through the open roll gaps of the finishing stands.
Durch das unmittelbare Vorordnen des Vorgerüstes vor dem vorderen Reversierhaspel wird es demnach in vorteilhafter Weise möglich, nach den gewünschten Vorstichen am Vorgerüst kontinuierliche Stiche in allen drei Gerüsten und anschließend die Fertigstiche an den beiden Reversiergerüsten im Tandembetrieb auszuführen, so daß das Walzgut bei noch zulässigen Endtemperaturen zu dünnen Bändern unter 2 mm Dicke ausgewalzt werden kann. Die Oberflächenqualität des Walzgutes wird dabei durch das Vorgerüst nicht beeinträchtigt, weil dem Vorgerüst die beiden Reversiergerüste als Fertiggerüste nachgeordnet sind und die letzten Stiche mit diesen Fertiggerüsten alleine ausgeführt werden können. Durch die mögliche rasche Dickenreduktion wird aber nicht nur eine ausreichende Endtemperatur sichergestellt, sondern auch eine erhebliche Kapazitätssteigerung erzielt, wobei mittlere und höhere Bundgewichte zum Einsatz kommen können.By directly arranging the roughing stand in front of the front reversing reel, it is therefore advantageously possible to carry out continuous stitches in all three stands after the desired preliminary stitches on the roughing stand and then to carry out the finishing stitches on the two reversing stands in tandem operation, so that the rolling stock is still permissible at the final temperatures can be rolled into thin strips less than 2 mm thick. The surface quality of the rolling stock is not affected by the roughing stand, because the two reversing stands are arranged downstream of the roughing stand as finishing stands and the last passes can be carried out with these finishing stands alone. The possible rapid reduction in thickness not only ensures a sufficient final temperature, but also achieves a considerable increase in capacity, whereby medium and high coil weights can be used.

Entsprechend der Fig. 2 wird das Walzgut in einem Ofen 1 auf die gewünschte Walztemperatur gebracht. Das erwärmte Walzgut wird dann in einem Zunderwäscher 2 entzundert, bevor es den Walzgerüsten, einem Vorgerüst 3 und zwei als Fertiggerüste dienenden Reversiergerüsten 4 zugeleitet wird. Diesen Reversiergerüsten 4 sind zwei Reversierhaspeln 5 und 6 vor- und nachgeordnet, wobei zur Vermeidung höherer Temperaturverluste die Reversierhaspel 5 und 6 entweder mit einem beheizbaren Dorn oder mit einer Wärmehaube ausgerüstet sein können. Das fertiggewalzte Warmband wird anschließend auf einem Haspel 7 aufgewickelt. Zum Beschneiden der Bandanfänge und -enden ist zwischen dem hinteren Reversiergerüst 4 und dem hinteren Reversierhaspel 6 eine Schopfschere 8 vorgesehen. Die gewählte Anordnung der Schopfschere 8 bietet den erheblichen Vorteil, daß sowohl der Bandanfang als auch das Bandende nach den Fertigstichen zusätzlich beschnitten werden kann.2, the rolling stock is brought to the desired rolling temperature in an
Der Transport des Walzgutes erfolgt in üblicher Weise auf Rollgängen 9, wobei den Haspeln 5,6 und 7 jeweils angetriebene Treibrollen 10 eines Treibers 11 vorgeordnet sind.The rolling stock is transported in the usual way on roller tables 9, the driven
Die dargestellte Anlage zum Warmwalzen von band-oder tafelförmigem Walzgut unterscheidet sich von üblichen Warmwalzanlagen vergleichbarer Art vor allem dadurch, daß das Vorgerüst 3 den beiden als Fertiggerüste dienenden Reversiergerüsten 4 mit einem geringstmöglichen Abstand vorgelagert ist so daß zwischen dem Vorgerüst 3 und dem vorderen Reversiergerüst 4 der Reversierhaspel 5 gerade Platz findet. Damit wird nicht nur der sonst übliche Rollgang zur Aufnahme des Bandes für die Vorstiche unnötig, sondern es ergibt sich der Vorteil, daß alle Gerüste von einem wahlweisen Einzelbetrieb auf einen gemeinsamen Betrieb bzw. einen Tandembetrieb umgestellt werden können. Nach den erforderlichen Vorstichen am Vorgerüst 3 kann somit durch den gleichzeitigen Einsatz aller drei Gerüste bzw. durch den Tandembetrieb der Reversiergerüste 4 eine sehr rasche Dickenabnahme des Walzgutes erzielt werden, so daß die Wärmeverluste auf ein Minimum beschränkt werden können. Dabei wird durch die Aufteilung der Gerüste in ein Vorgerüst und zwei Fertiggerüste eine einwandfreie Oberfläche des Walzgutes sichergestellt.The system shown for hot rolling strip or sheet-shaped rolling stock differs from conventional hot rolling systems of a comparable type primarily in that the roughing
