Definitions
- the invention relates to a system for producing hot-rolled steel strip from a continuously cast starting material, in which the cast strand is wound up into a bundle in a reel station after leaving the continuous casting system and is reeled off in a further coiler station after the bundle has been moved, and the reel stations are fed in are arranged in a common oven.
- Such systems are known. They have the advantage that continuously produced hot-rolled strip from a continuously cast starting material is inexpensive because a considerable saving in energy is made possible solely by the fact that the facilities necessary for reheating the slabs, intermediate transport devices and storage spaces are not required in conventional processes and systems.
- the cast strand which has already been cast in the form of a strip makes it unnecessary to reduce the cross section with a high degree of deformation effort and high deformation energy and permits coils to be wound up immediately behind the continuous casting installation. This winding or reeling is necessary because the maximum casting speed at which the cast strand leaves the continuous caster is much lower than the lowest possible rolling speed of conventional roll stands.
- the object of the present invention is to improve the arrangement of the reel stations within the furnace in such a way that unproblematic reeling and unwinding of the cast strip and, if appropriate, intermediate storage is possible and the implementation of the federal government is simplified.
- winding mandrels circulate in the case of the invention, so that tape can also be wound and converted so that winding cannot be carried out on mandrelless winding devices.
- the winding mandrels are driven independently of one another and the drives which are fixed relative to the orbit of the winding mandrels are detachably coupled to the winding mandrels. This is recommended because the winding mandrels have to work with different drive speeds due to the different speeds for reeling and unwinding. If necessary, the winding mandrels can be brought into the respective winding position step by step and can be coupled there to the drives.
- a further feature of the invention provides that a device for controlled heating of the cast strand to the reel or the rolling temperature is arranged in front of and / or behind the furnace. Such devices can of course be omitted if the temperature of the furnace allows rolling without reheating or the temperature of the greeting line corresponds to the reel temperature.
- cross winding shears and / or devices for descaling be arranged downstream of the winding mandrels in a manner known per se.
- the cross-cut shear is required when the cast strand weight is greater than the coil weight of the coil located in the take-up reel station.
- Descaling equipment is usually required behind the furnace to prevent the scale from rolling into the mill.
- Fig. 1 the continuous casting system is indicated at 1.
- the cast strand B passes through a pair of scissors at 2 before it is introduced into the furnace 3 with the aid of the driver 6 and wound up on the mandrel 4.
- the winding mandrel 4 can be moved on the circular orbit U shown in dashed lines in the direction of the arrow into a position in which the winding mandrel 5 is drawn in FIG. 2.
- the cast strand B is unwound from the winding mandrel 5 with the aid of the driving apparatus 7 and is fed to the rolling mill 10 through the heating device 8, the cast strand B having previously passed through the descaling device 9.
- a cooling section is indicated at 11, in which the strip is cooled before it is wound up at 12.
- FIG. 3 shows an alternative in which four mandrels 4, 4a, 5, 5b are arranged so as to be movable on the orbit U.
- the winding mandrels have the same spacing from one another and allow intermediate storage of wound bundles in the stations 4a and 5a.
- the device for heating the cast strand can also be located between continuous casting installation 1 and furnace 3; it can also be a special device only for heating the strip edges.

Description
- Die Erfindung betrifft eine Anlage zum Herstellen von warmgewalztem Stahlband aus einem stranggegossenen Vormaterial, bei der der Gußstrang nach dem Verlassen der Stranggießanlage in einer Haspelstation zu einem Bund aufgehaspelt und nach Umsetzen des Bundes in einer weiteren Haspelstation abgehaspelt einem Walzwerk zugeführt wird, wobei die Haspelstationen in einem gemeinsamen Ofen angeordnet sind.
- Derartige Anlagen sind bekannt. Sie haben den Vorteil, daß kontinuierlich hergestelltes warmgewalztes Band aus einem stranggegossenen Vormaterial kostengünstig ist, weil eine erhebliche Einsparung an Energie allein dadurch ermöglicht wird, daß die bei herkömmlichen Verfahren und Anlagen notwendigen Einrichtungen zum Wiedererwärmen der Brammen, Zwischentransporteinrichtunge und Lagerplätze entfallen. Der bereits bandförmig gegossene Gußstrang macht eine Reduzierung des Querschnittes mit hohem verformungsaufwand und hoher Verformungsenergie entbehrlich und gestattet, ein Aufwickeln des Gußstranges unmittelbar hinter der Stranggießanlage zu Bunden. Dieses Aufwickeln oder Aufhaspeln ist deshalb notwendig, weil die maximale Gießgeschwindigkeit, mit der der Gußstrang die Stranggießanlage verläßt, viel geringer ist als die niedrigstmögliche Walzgeschwindigkeit herkömmlicher Walzgerüste.
- Es ist deshalb durch die gattungsbildende DE-C-32 41 745 vorgeschlagen worden, den Gußstrang in einem Ofen dornlos zu einem Bund zu wickeln und nach Umsetzen des Bundes dieses diskontinuierlich wieder abzuwickeln und einem Walzwerk zuzuführen. Zum Wickeln wird eine als Coil-Box bekannte dornlose Einrichtung verwendet, mit der relativ dicke Gußstränge gewickelt werden können.
- Die bekannte Anlage mit der Anordnung der dornlosen Haspelstationen innerhalb des Ofens ist konstruktiv ungünstig und sehr aufwendig. Außerdem ist das wickeln ohne Dorn nur für relativ dicke Gußstränge als betriebssicher anzusehen.
- Aufgabe der vorliegenden Erfindung ist, ausgehend von dem vorstehend beschriebenen Stand der Technik, die Anordnung der Haspelstationen innerhalb des Ofens so zu verbessern, daß ein problemloses Auf- und Abhaspeln des Gußbandes und ggf. Zwischenspeichern möglich und das Umsetzen des Bundes vereinfacht wird.
- Gelöst wird diese Aufgabe erfindungsgemäß mit den Merkmalen im Anspruch 1.
- Anders als beim Stand der Technik laufen bei der Erlindung Wickeldorne um, so daß auch Band gewickelt und umgesetzt werden kann, daß auf dornlosen Wickeleinrichtungen nicht gewickelt werden kann.
- In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Wickeldorne unabhängig voneinander angetrieben und die relativ zur Umlaufbahn der Wickeldorne feststehenden Antriebe mit den Wickeldornen lösbar gekuppelt sind. Dies empfiehlt sich, da die Wickeldorne aufgrund der unterschiedlichen Geschwindigkeiten zum Aufhaspeln und Abhaspeln mit unterschiedlichen Antriebsgeschwindigkeiten arbeiten müssen. Die Wickeldorne können gegebenenfalls schrittweise in die jeweilige Wickelposition gebracht werden und dort mit den Antrieben gekoppelt werden.
- Sofern die Temperatur des Gußstranges nicht die für das Haspeln oder Walzen notwendigen Werte aufweist, ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß vor und/oder hinter dem Ofen eine Vorrichtung zum gesteuerten Erwärmen des Gußstranges auf Haspel oder Walztemperatur angeordnet ist. Solche Einrichtungen können selbstverständlich entfallen, wenn die Temperatur des Ofens ein Walzen ohne Nacherwärmung ermöglicht bzw. die Temperatur des Grußstranges der Haspeltemperatur entspricht.
- Schließlich wird vorgeschlagen, daß den Wickeldornen in an sich bekannter Weise eine Querteilschere vor- und/oder Einrichtungen zum Entzundern nachgeordnet sind. Die Querteilschere ist dann erforderlich, wenn das Gußstranggewicht größer als das Bundgewicht des in der Aufwickelhaspelstation befindlichen Bundes ist. Einrichtungen zum Entzundern sind in der Regel hinter dem Ofen erforderlich, um ein Einwalzen des Zunders im Walzwerk zu verhindern.
- Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachfolgend beschrieben. Es zeigt:
- Fig. 1 die grob vereinfachte Ansicht einer Anlage zum Herstellen von warmgewalztem Stahlband mit einem Ofen,
- Fig. 2 eine vergrößerte Ansicht des Ofens nach Fig. 1,
- Fig. 3 eine Darstellung des Ofens nach Fig. 2 mit vier Wickeldornen.
- In Fig. 1 ist bei 1 die Stranggießanlage angedeutet. Der Gußstrang B durchläuft bei 2 eine Schere, bevor er mit Hilfe des Treibers 6 in den Ofen 3 eingeführt und auf dem Wickeldorn 4 aufgehaspelt wird.
- Wie in Fig. 2 vergrößert dargestellt, ist der Wickeldorn 4 auf der gestrichelt gezeichneten kreisförmigen Umlaufbahn U in Pfeilrichtung in eine Position verbringbar, in der in Fig. 2 der Wickeldorn 5 gezeichnet ist. Von dem Wickeldorn 5 wird mit Hilfe des Treibapparates 7 der Gußstrang B abgewickelt und durch die Vorrichtung zum Erwärmen 8 hindurch dem Walzwerk 10 zugeführt, wobei der Gußstrang B zuvor die Einrichtung zum Entzundern 9 durchläuft. Bei 11 ist eine Kühlstrecke angedeutet, in der das Band abgekühlt wird, bevor es bei 12 aufgehaspelt wird.
- In Fig. 3 ist eine Alternative dargestellt, bei der vier Wickeldorne 4, 4a, 5, 5b auf der Umlaufbahn U bewegbar angeordnet sind. Die Wickeldorne haben gleiche Abstände voneinander und gestatten ein Zwischenspeichern von gewickelten Bunden in den Stationen 4a und 5a.
- In einer nicht dargestellten Variante kann die Vorrichtung zur Erwärmung des Gußstranges sich auch zwischen Stranggießanlage 1 und Ofen 3 befinden; sie kann auch eine spezielle Vorrichtung nur zum Erwärmen der Bandkanten sein.
