Abstract

Operating a rolling plant incorporates one or more preliminary upsetting stands followed by a compact rolling group which is laterally offset and consists of two universal or duo stands (UG1, UG2) and an interposed upsetting stand (ZG). Blanks from the casting installation are fed directly (without intermediate storage) to the rolling plant. Within a predetermined time interval they are rolled into finished profiles and fed onto a laterally offset cooling bed (KB), after which new blanks enter into the compact rolling group. In cases where the time required for finish rolling is longer than the predetermined time interval (which depends on the output rate of the casting installation) a length of the finished product emerging from the compact rolling group is cut off and fed onto the cooling bed.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Walzen von profilierten Walzsträngen in einer Walzgerüstanordnung, die aus einem ersten und einem zweiten Universalgerüst oder Duo-Gerüst und einem, zwischen diesen Gerüsten angeordnetem Stauch-Zwischengerüst besteht, hinter der ein Auslaufrollgang mit seitlich zu diesem angeordneten Kühlbett angeordnet ist, bei dem die Vorprofilwalzgutstränge aus einer Stranggußeinrichtung in einem, von deren Leistung bestimmten Zeittakt austretend, der Walzgerüstanordnung zugeführt, in einer Mehrzahl von Stichen und Reversierstichen fertiggewalzt, auf den Auslaufrollgang aufgebracht und von diesem auf ein seitlich angeordnetes Kühlbett abgeschoben werden.The invention relates to a method for rolling profiled Rolling strands in a roll stand arrangement consisting of a first and a second universal scaffold or duo scaffold and one between these scaffolds arranged intermediate compression frame, behind which an outfeed roller table is arranged laterally to this arranged cooling bed, in which the Pre-profile rolled strands from a continuous casting device in one, of whose Power exiting a certain time cycle, fed to the roll stand arrangement, in a plurality of stitches and reversing stitches are rolled onto the Spout roller table applied and from this to a laterally arranged cooling bed getting deported.

Bei diesem bekannten Verfahren weist das, hinter der Kompaktwalzgruppe angeordnete Kühlbett eine Transportbreite auf, die der Länge des fertiggewalzten Walzgutstranges entspricht. Diese Anordnung erlaubt es, die Walzanlage im Zeittakt mit der Strangußeinrichtung kontinuierlich zu betreiben, wenn die von der Walzanlage erbrachte Leistung der Formung des Vorprofils in den Walzgutfertigstrang die gleiche oder eine kleinere Zeitspanne benötigt, die auch die Stranggußeinrichtung braucht, um ein Vorprofil herzustellen. In this known method, this points behind the compact rolling group arranged cooling bed on a transport width that the length of the finished rolled Corresponds to rolling stock. This arrangement allows the rolling mill to be timed to operate continuously with the continuous casting device when the from the rolling mill performed the shaping of the preliminary profile in the finished rolled strand same or a shorter period of time, which also the continuous casting device needs to create a preliminary profile.

Mit abnehmenden Querschnitt und entsprechend abnehmenden Gewicht pro Längeneinheit des zu formenden Walzgutfertigstrangs wird die zeitliche Leistung der Walzgerüstanordnung kleiner, d. h. für das Fertigwalzen von profilierten Walzgutsträngen wird um so mehr Zeit benötigt, je kleiner die zu erzielenden Profil-Fertigquerschnitte sind, weil dazu eine entsprechend größer werdende Anzahl von Stichen und Reversierstichen in der Kompaktwalzgruppe erforderlich ist, und von einer bestimmten Profilgröße an reicht die Leistung der Walzgerüstanordnung nicht mehr aus, die Produktion der Strangießeinrichtung im Zeittakt zu verarbeiten. Es müssen dann aufwendige Zwischenlagerungen der, von der Stranggußeinrichtung produzierten Vorprofile vorgenommen werden. Die erwähnte, von der Stranggußeinrichtung vorgegebene Zeitspanne zwischen den, von dieser nacheinander ausgebrachten Vorprofilen setzt deshalb für die Größe der, mit der Kompaktwalzgruppe walzbaren Fertigquerschnitte eine Grenze. Kleinere, unterhalb dieser Grenze liegende Fertigprofile können nicht gewalzt werden.With decreasing cross section and correspondingly decreasing weight per The unit of length of the finished strand to be formed is the temporal performance of the Roll stand arrangement smaller, d. H. for the finish rolling of profiled Rolls of rolled material are required the more time, the smaller the finished profile cross-sections to be achieved are because a correspondingly increasing number of Stitches and reversing stitches are required in the compact rolling group, and by a certain profile size, the performance of the roll stand arrangement is not sufficient more from processing the production of the continuous caster in time. It then need elaborate interim storage, of the continuous casting produced pre-profiles. The mentioned from the Continuous casting device predetermined period of time between, by this successively applied pre-profiles therefore sets for the size of the with Compact rolling group of millable finished cross sections a limit. Smaller, below finished profiles within this limit cannot be rolled.

Der Erfindung liegt die Aufgabe zugrunde, diese Grenze zu beseitigen und die Möglichkeit zu schaffen, mit der beschriebenen Walzanlage auch Profilquerschnitte zu walzen deren Größe unterhalb dieser Grenze liegen.The invention has for its object to eliminate this limit and the Possibility to create profile cross-sections with the rolling mill described to roll whose size is below this limit.

Die Lösung dieser Aufgabe besteht darin, daß der fertig gewalzte, auf dem Auslaufrollgang abgelegte Walzgutstrang mit einem vorderen Abschnitt neben das Kühlbett gebracht, vor diesem geteilt und der abgeteilte vordere Abschnitt auf das Kühlbett aufgebracht, und, unmittelbar daran anschließend der hintere Abschnitt des Walzgutstranges ebenfalls neben das Kühlbett transportiert und auf dieses aufgebracht werden, und dass während des ersten Aufbringvorgangs bereits der, aus der Stranggußeinrichtung kommende folgende Vorprofil-Walzgutstrang in die Walzgerüstanordnung eingebracht und mit dessen Walzung begonnen wird.The solution to this problem is that the finished rolled on the Roll-out run of rolled material with a front section next to it Brought cooling bed, divided in front of this and the divided front section on the Cooling bed applied, and, immediately afterwards, the rear section of the Rolled material strand also transported next to the cooling bed and on this are applied and that during the first application process the coming from the continuous casting device following pre-profile rolling stock in the Roll stand arrangement introduced and the rolling of which is started.

Bereits mit Beginn und während dieses Aufschiebens des hinteren Abschnitts kann dann bereits der nächstfolgende, aus der Stranggußeinrichtung kommende Vorprofilstrang in die Kompaktwalzgruppe eingebracht und in dieser reversierend gewalzt werden, weil der Auslaufrollgang inzwischen freigemacht wurde und zwar schneller als dies bei dem bekannten Walzverfahren der Fall war. Das Walzen des, jeweils nachfolgenden Vorprofils kann bereits beginnen, wenn der vorhergehende Walzvorgang noch nicht abgeschlossen ist, d. h. für jeden der einander überschneidenden Walzvorgänge in der Kompaktwalzgruppe steht jeweils absolut mehr Zeit und damit die Möglichkeit einer Erhöhung der Stichzahl zur Verfügung, die es wiederum erlaubt kleinere, jenseits der erwähnten Größengrenze liegende Querschnitte zu walzen.Already with the beginning and during this postponement of the rear section can then already be the next one coming from the continuous casting device Introduced pre-profile strand in the compact rolling group and reversing in this be rolled because the run-out roller table has now been cleared faster than was the case with the known rolling process. The rolling of the the following previous profile can already begin if the previous one Rolling is not yet complete, d. H. for each other overlapping rolling processes in the compact rolling group stands absolutely more time and thus the possibility of increasing the number of stitches available it in turn allows smaller ones that are beyond the size limit mentioned Roll cross sections.

Wie die Erfindung weiter vorsieht, kann das geschilderte Verfahren auch abweichend so abgewickelt werden, daß der fertig gewalzte, auf den Auslaufrollgang abgelegte Walzgutstrang mit einem hinteren Abschnitt neben das Kühlbett gebracht, hinter diesem geteilt und der abgeteilte hintere auf das Kühlbett aufgebracht und unmittelbar daran anschließend der vordere Abschnitt des Walzgutstrangs durch den Auslaufrollgang neben das Kühlbett zurückbefördert, auf dieses aufgebracht werden, und dass während des ersten Aufbringvorgangs bereits der aus der Stranggußeinrichtung kommende folgende Vorprofil-Walzgutstrang in die Walzgerüstanordnung eingebracht und mit dessen Walzung begonnen wird.As the invention further provides, the described method can also be different so that the finished rolled, placed on the outlet roller table Rolled material strand with a rear section placed next to the cooling bed, behind this divided and the divided rear applied to the cooling bed and immediately afterwards the front section of the rolled material strand through the Discharge roller table back next to the cooling bed, be applied to this, and that during the first application process the one from the Continuous casting device coming following pre-profile rolling stock in the Roll stand arrangement introduced and the rolling of which is started.

Bei der Ausbildung nach Fig. 1 besteht die Walzgerüstanlage aus dem Zuführrollgang R1, der, aus den Universalgerüsten UG1 und UG2 und dem zwischen diesen angeordneten Zwischengerüst bestehenden Kompaktwalzgruppe, dem dieser nachgeordneten Abfuhrrollgang R2 und der seitlich dieses Abfuhrrollgangs R2 und seitlich der Walzlinie WL angeordneten Kühlbett KB sowie einer vor dem Kühlbett KB befindlichen Trenneinrichung TR.1, the roll stand system consists of the Feed roller table R1, which, from the universal stands UG1 and UG2 and the existing compact rolling group between these intermediate stands, which this downstream discharge roller table R2 and the side this Discharge roller table R2 and the cooling bed KB arranged on the side of the rolling line WL as well a separating device TR located in front of the cooling bed KB.

Die Walzgerüstanlage wird in der Weise betrieben, daß der erste, die Kompaktwalzgruppe verlassende fertige Walzgutstrang PSTI auf dem Abfuhrrollgang R2 vor das Kühlbett gefahren und zum Stillstand gebracht wird. Anschließend wird dann mit Hilfe der Trenneinrichung TR, der vor dem Kühlbett KB liegende erste Längenabschnitt PSTI' abgetrennt und auf das Kühlbett aufgebracht. Anschließend wird der noch auf dem Abfuhrrollgang R2 liegende zweite Längenabschnitt PSTI" vor das Kühlbett KB gefahren und ebenfalls auf dieses aufgebracht. Zwischenzeitlich wurde der aus dem (nicht dargestellten) folgenden Vorprofil durch zunächst kurze Reversierstiche entstehende nächste, in unterbrochenen Linien angedeutete Walzgutstrang PSTII auf den Abfuhrrollgang R2 aufgebracht und nach seiner Fertigwalzung entsprechend geteilt und die entstandenen Längenabschnitte auf das Kühlbett aufgebracht.The mill stand is operated in such a way that the first one PSTI finished rolling strand leaving the compact rolling group on the Removal roller table R2 is moved in front of the cooling bed and brought to a standstill. Then, with the help of the separating device TR, the KB in front of the cooling bed lying first length section PSTI 'separated and applied to the cooling bed. Then the second is still on the discharge roller table R2 Length section PSTI "in front of the cooling bed KB and also on this upset. In the meantime, the following became (not shown) Preliminary profile created by short reversing stitches next, in broken lines indicated rolling stock strand PSTII on the discharge roller table R2 applied and divided accordingly after its finish rolling and the The resulting lengths are applied to the cooling bed.

Die Ausbildung der Walzgerätanlage nach Fig. 2 entspricht im Grundsatz der nach Fig. 1 mit der Maßgabe, daß das Kühlbett KB in einem, etwa der Länge eines Längenabschnitt eines geteilten Walzgutstranges entsprechenden geringeren Abstand von der Kompaktwalzgruppe angeordnet ist, und die Trenneinrichtung TR hier, in Walzlinie WL gesehen, hinter dem Kühlbett befindet. Der aus der Kompaktwalzgruppe austretende, auf dem Abfuhrrollgang R2 liegende Walzgutstrang PSTI wird hier, vor dem Kühlbett KB auf dem Abfuhrrollgang R2 liegend mit der Trenneinrichtung TR getrennt und dann, anders als bei der Ausbildung nach Fig. 1 zunächst der, in Transportrichtung gesehen, hintere Längenabschnitt PSTI" auf das Kühlbett KB aufgebracht. Anschließend wird der zweite Längenabschnitt PSTI' auf dem Rollgang R2 entgegen der Walzrichtung zurückgefahren, vor das Kühlbett KB gebracht und auf dieses aufgeschoben. Mit dem folgenden Walzgutstrang PSTII wird entsprechend der bei Fig. 1 geschilderten Weise verfahren; auch hier mit der Maßgabe, daß zunächst der hintere Längenabschnitt PSTI" und dann der vordere Längenabschnitt PSTI nach vorherigem Rücktransport auf das Kühlbett KB aufgebracht werden.2 corresponds in principle to that of FIG Fig. 1 with the proviso that the cooling bed KB in one, approximately the length of a Length section of a divided rolling stock correspondingly smaller Distance from the compact rolling group is arranged, and the separating device TR here, seen in the WL rolling line, behind the cooling bed. The one from the Compact roller group emerging, lying on the discharge roller table R2 Rolled material strand PSTI is here, in front of the cooling bed KB on the discharge roller table R2 lying separated with the separator TR and then, unlike the 1 first of the rear, seen in the direction of transport Length section PSTI "is applied to the cooling bed KB second length section PSTI 'on the roller table R2 against the rolling direction retracted, brought in front of the cooling bed KB and pushed onto this. With the following strand PSTII is corresponding to that described in FIG. 1 Proceed wisely; also here with the proviso that the rear Length PSTI "and then the front length PSTI after previous return transport are applied to the cooling bed KB.
