Definitions
- the invention relates to a system for hot rolling strip or sheet-shaped rolling stock with a reversible roughing stand and a reversible finishing stand.
- the required final rolling temperatures can hardly be maintained, especially in the case of thin hot strips, especially with higher coil weights, which complicates the fact that due to the high number of individual passes on the finishing stand required for a corresponding quality of the rolling stock, there is a further considerable temperature loss is to be expected.
- the strips to be rolled can only be descaled with one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be ruled out. Because of the unavoidable temperature losses, there is finally a lower limit of the strip thickness that can be achieved, because with strip thicknesses of about 2 mm the permissible strip end temperature is already reached.
- 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 can also be guaranteed for medium and high coil weights can.
- the invention solves the problem in that the roughing stand and the finishing stand are arranged immediately one behind the other and can be converted from optional individual operation to tandem operation.
- the direct succession of the two rolling stands makes it possible in an advantageous manner to drive the roughing stand and the finishing stand in a tandem operation, which, with good use of the capacity of the roughing stand, allows a rapid reduction in the thickness of the rolling stock, so that the rolling stock is still too thin at permissible final temperatures can be rolled out.
- the surface quality of the rolling stock is not affected by the roughing stand, because the finishing stand is arranged after the finishing stand and the last stitch or the last pass can be carried out with the finishing stand alone.
- the usual heads are of course carried out on the roughing stand.
- the achievable rapid reduction in thickness of the rolled stock not only ensures a sufficient final temperature for hot strips with a thickness of less than 2 mm, but also increases capacity compared to hot rolling mills with separate roughing and finishing stands.
- 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 roughing stand 3 and the finishing stand 4 directly adjoining the roughing stand 3.
- furnaces 5 are arranged upstream and downstream of these two stands 3 and 4 in order to avoid excessive temperature losses.
- the hot rolled strip is wound on a reel 6, which is preceded by a pair of scissors 7.
- drivers 9 are provided at corresponding locations.
- the system shown differs from conventional hot rolling systems of a comparable type in that the roughing stand 3 and the finishing stand 4 lie directly one behind the other and can be switched from an optional individual operation to a tandem operation.
- a very rapid reduction in the thickness of the rolling stock can consequently be achieved by the simultaneous use of both stands 3 and 4.
- the rolling capacity is increased and the length of the rolling mill is reduced by about 1/3, which is associated with a considerable reduction in investment costs.
- the surface quality is further improved by separating pre-stitches and finished stitches, whereby the work rolls have a comparatively long service life due to the possible division into individual stitches. It does not need to be explained in more detail that the arbitrary use of one of the two scaffolds or both scaffolds can meet a wide variety of requirements.

Description
Die Erfindung bezieht sich auf eine Anlage zum Warmwalzen von band- oder tafelförmigem Walzgut mit einem reversierbaren Vorgerüst und einem reversierbaren Fertiggerüst.The invention relates to a system for hot rolling strip or sheet-shaped rolling stock with a reversible roughing stand and a reversible finishing stand.
Um bei Warmwalzanlagen, die für eine geringere oder mittlere Kapazität ausgelegt sind, die Vor- und Fertigstiche nicht mit einem einzigen Arbeitswalzenpaar durchführen zu müssen, ist es bekannt, ein Vorgerüst und getrennt davon ein Fertiggerüst einzusetzen. Dadurch wird der Vorteil erreicht, dass die Walzenrauhigkeit und der Walzendurchmesser an die jeweiligen Erfordernisse des Verformungsvorganges angepasst werden können, weil für die Vorstiche Arbeitswalzen mit einem grösseren Durchmesser und einer grösseren Walzenrauhigkeit verwendet werden können. Mit diesem Vorteil wird allerdings der Nachteil erkauft, dass die Kapazität des Vorgerüstes schlecht ausgenützt wird und dass ein vergleichsweise hoher Temperaturverlust durch den notwendigen Transport des Walzgutes zum Fertiggerüst unvermeidbar ist. Dies hat zur Folge, dass insbesondere bei dünnen Warmbändern die erforderlichen Endwalztemperaturen kaum eingehalten werden können, vor allem bei höheren Bundgewichten, wobei erschwerend hinzukommt, dass aufgrund der für eine entsprechende Qualität des Walzgutes erforderlichen hohen Anzahl von Einzelstichen auf dem Fertiggerüst mit einem weiteren erheblichen Temperaturverlust zu rechnen ist. 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 dementsprechend kaum auszuschliessen. Wegen der unvermeidbaren Temperaturverluste ergibt sich schliesslich eine Beschränkung der erreichbaren Banddicke nach unten, weil bei Banddicken von etwa 2 mm bereits die zulässige Bandendtemperatur erreicht wird.It is known to use a roughing stand and, separately from it, a finishing stand in hot rolling systems which are designed for a lower or medium capacity to not have to carry out the preliminary and finishing passes with a single pair of work rolls. This has the advantage that the roller roughness and the roller diameter can be adapted to the respective requirements of the shaping process, because work rolls with a larger diameter and a greater roller roughness can be used for the preliminary stitches. With this advantage, however, the disadvantage is paid that the capacity of the roughing stand is poorly utilized and that a comparatively high temperature loss due to the necessary transport of the rolling stock to the finishing stand is unavoidable. As a result, the required final rolling temperatures can hardly be maintained, especially in the case of thin hot strips, especially with higher coil weights, which complicates the fact that due to the high number of individual passes on the finishing stand required for a corresponding quality of the rolling stock, there is a further considerable temperature loss is to be expected. In addition, the strips to be rolled can only be descaled with one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be ruled out. Because of the unavoidable temperature losses, there is finally a lower limit of the strip thickness that can be achieved, because with strip thicknesses of about 2 mm the permissible strip end temperature is already reached.
Damit mit einer geringeren Stichanzahl das Auslangen gefunden werden kann, was geringere Temperaturverluste ergibt, ist es bereits bekannt (FR-A-1 132 772), zwei oder drei Gerüste unmittelbar hintereinander anzuordnen, so dass das Walzgut in den Gerüsten gleichzeitig gewalzt und folglich entsprechend weniger Durchläufe notwendig werden. Nachteilig bei diesen bekannten Walzanlagen ist wiederum, dass durch die gleichartigen Gerüste keine Anpassung der Walzendurchmesser und der Walzenrauhigkeit an die jeweiligen Erfordernisse möglich ist. Das Vorordnen eines Vorgerüstes würde bei solchen zwei- bzw. dreigerüstigen Anlagen die durch das Vorgerüst bedingten Nachteile nicht ausschalten.So that it can be found with a smaller number of passes, which results in lower temperature losses, it is already known (FR-A-1 132 772) to arrange two or three stands directly one behind the other, so that the rolling stock is rolled in the stands simultaneously and consequently accordingly fewer runs are necessary. A disadvantage of these known rolling plants is, in turn, that due to the similar stands, it is not possible to adapt the roll diameter and the roughness to the respective requirements. The arrangement of a roughing stand would not eliminate the disadvantages caused by the roughing stand in such two- or three-stand systems.
Um die Arbeitswalzen besser ausnützen zu können, ohne die Oberflächenqualität des Walzgutes zu beeinträchtigen, ist es schliesslich bekannt (US-A-3 331 232), zwei gleichartige Gerüste unmittelbar nacheinander anzuordnen sowie das eine Gerüst als Vorgerüst und das andere als Fertiggerüst einzusetzen. Ist die Oberflächenqualität der Arbeitswalzen des als Fertiggerüst betriebenen Walzgerüstes für ein Fertigwalzen nicht mehr tragbar, so wird dieses Gerüst als Vorgerüst verwendet, weil für ein Vorwalzen an die Arbeitswalzen keine so hohen Anforderungen gestellt werden. Das als Vorgerüst eingesetzte Walzgerüst wird nach einem Wechsel der Arbeitswalzen zum Fertiggerüst mit Arbeitswalzen hoher Qualität. Nachteilig bei solchen Anlagen ist, dass der Arbeitswalzendurchmesser für das Vor- und Fertigwalzen gleich gross sein muss und dass die notwendige Anzahl der Durchläufe nicht reduziert werden kann, weil die beiden Gerüste nur einzeln betrieben werden können. Als Folge davon ist wiederum mit höheren Temperaturverlusten und einer Beschränkung der erreichbaren Banddicke nach unten zu rechnen.Finally, in order to be able to make better use of the work rolls without impairing the surface quality of the rolling stock, it is known (US Pat. No. 3,331,232) to arrange two similar stands directly one after the other and to use one stand as a rough stand and the other as a finishing stand. If the surface quality of the work rolls of the rolling stand operated as a finishing stand is no longer sustainable for a finish rolling, this stand is used as a roughing stand, because the work rolls are not subject to such high demands for pre-rolling. The roll stand used as a roughing stand becomes a finished stand with high quality work rolls after changing the work rolls. The disadvantage of such systems is that the work roll diameter for the roughing and finishing rolls must be the same and that the necessary number of passes cannot be reduced because the two stands can only be operated individually. As a consequence, higher temperature losses and a lower limit of the strip thickness that can be achieved can be expected.
Der Erfindung liegt demnach 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 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 can also be guaranteed for medium and high coil weights can.
Die Erfindung löst die gestellte Aufgabe dadurch, dass das Vorgerüst und das Fertiggerüst unmittelbar hintereinander angeordnet und vom wahlweisen Einzelbetrieb auf einen Tandembetrieb umstellbar sind.The invention solves the problem in that the roughing stand and the finishing stand are arranged immediately one behind the other and can be converted from optional individual operation to tandem operation.
Durch das unmittelbare Aufeinanderfolgen der beiden Walzgerüste wird es in vorteilhafter Weise möglich, das Vorgerüst und das Fertiggerüst in einem Tandembetrieb zu fahren, der unter einer guten Kapazitätsausnützung des Vorgerüstes eine rasche Dickenreduktion des Walzgutes erlaubt, so dass das Walzgut noch bei zulässigen Endtemperaturen zu dünnen Stärken ausgewalzt werden kann. Die Oberflächenqualität des Walzgutes wird dabei durch das Vorgerüst nicht beeinträchtigt, weil dem Vorgerüst das Fertiggerüst nachgeordnet ist und der letzte Stich bzw. die letzten Stiche mit dem Fertiggerüst allein ausgeführt werden können. Die üblichen Vorstiehe werden selbstverständlich am Vorgerüst durchgeführt.The direct succession of the two rolling stands makes it possible in an advantageous manner to drive the roughing stand and the finishing stand in a tandem operation, which, with good use of the capacity of the roughing stand, allows a rapid reduction in the thickness of the rolling stock, so that the rolling stock is still too thin at permissible final temperatures can be rolled out. The surface quality of the rolling stock is not affected by the roughing stand, because the finishing stand is arranged after the finishing stand and the last stitch or the last pass can be carried out with the finishing stand alone. The usual heads are of course carried out on the roughing stand.
Durch die erreichbare rasche Dickenreduktion des Walzgutes kann nicht nur eine ausreichende Endtemperatur für Warmbänder mit einer Dicke unter 2 mm sichergestellt, sondern auch eine Kapazitätssteigerung gegenüber Warmwalzanlagen mit getrenntem Vor- und Fertiggerüst erreicht werden.The achievable rapid reduction in thickness of the rolled stock not only ensures a sufficient final temperature for hot strips with a thickness of less than 2 mm, but also increases capacity compared to hot rolling mills with separate roughing and finishing stands.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt.The subject matter of the invention is shown in the drawing, for example.
Es zeigen:
- Fig. 1 eine erfindungsgemässe Anlage zum Warmwalzen von band- odertafelförmigem Walzgut in Seitenansicht und
- Fig. 2 eine Warmwalzanlage nach der Erfindung in einem Blockschaltbild.
- Fig. 1 shows an inventive system for hot rolling of strip or sheet-shaped rolling stock in side view
- Fig. 2 shows a hot rolling mill according to the invention in a block diagram.
Wie vor allem der Fig. 2 entnommen werden kann, wird das Walzgut in einem Ofen 1 auf die gewünschte Walztemperatur gebracht. Das erwärmte Walzgut wird dann in einem Zunderwäscher 2 entzundert, bevor es dem Vorgerüst 3 und dem unmittelbar an das Vorgerüst 3 anschliessenden Fertiggerüst 4 zugeleitet wird. Diesen beiden Gerüsten 3 und 4 sind Warmhalteöfen 5 vor- und nachgeordnet, um zu hohe Temperaturverluste zu vermeiden. Das fertiggewalzte Warmband wird auf einem Haspel 6 aufgewickelt, dem eine Schere 7 vorgeordnet ist. Zum Antrieb des Walzgutes auf einem Rollgang 8 sind Treiber 9 an entsprechenden Stellen vorgesehen.As can be seen above all from FIG. 2, the rolling stock is brought to the desired rolling temperature in an
Die dargestellte Anlage unterscheidet sich von üblichen Warmwalzenanlagen vergleichbarer Art dadurch, dass das Vorgerüst 3 und das Fertiggerüst 4 unmittelbar hintereinanderliegen und von einem wahlweisen Einzelbetrieb auf einen Tandembetrieb umgestellt werden können. Nach den erforderlichen Vorstichen kann folglich durch den gleichzeitigen Einsatz beider Gerüste 3 und 4 eine sehr rasche Dikkenabnahme des Walzgutes erzielt werden. Damit wird der Temperaturhaushalt wesentlich verbessert, was zu einer besseren Entzunderung und einer Steigerung der Oberflächenqualität führt. Darüber hinaus wird die Walzkapazität vergrössert und die Länge der Walzanlage um etwa 1/3 verringert, was mit einer erheblichen Verringerung der Investititionskosten verbunden ist. Die Oberflächenqualität wird schliesslich durch das Trennen von Vor- und Fertigstichen weiter verbessert, wobei sich für die Arbeitswalzen wegen der möglichen Aufteilung in Einzelstiche eine vergleichsweise hohe Standzeit ergibt. Dass durch den beliebigen Einsatz eines der beiden Gerüste oder beider Gerüste unterschiedlichsten Anforderungen Rechnung getragen werden kann, braucht wohl nicht näher ausgeführt zu werden.The system shown differs from conventional hot rolling systems of a comparable type in that the roughing
