Description

Die Erfindung betrifft eine Anlage zum Herstellen von warmgewalztem Stahl­ band aus einem stranggegossenen Vormaterial, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a plant for producing hot-rolled steel band from a continuously cast material, according to the preamble of Claim 1.

Derartige Anlagen sind bekannt. Sie haben den Vorteil, daß kontinuierlich hergestelltes warmgewalztes Band aus einem stranggegossenen Vormaterial kostengünstig ist, weil eine erheblichliche Einsparung an Energie allein daduch ermöglicht wird, daß die bei herkömmlichen Verfahren und Anlagen notwendigen Einrichtungen zum Wiedererwärmen der Brammen, Zwischentransporteinrichtungen 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 Strang­ gießanlage zu Bunden. Dieses Aufwickeln oder Aufhaspeln ist deshalb not­ wendig, weil die maximale Gießgeschwindigkeit, mit der der Gußstrang die Stranggießanlage verläßt, viel geringer ist als die niedrigstmögliche Walzgeschwindigkeit herkömmlicher Walzgerüste.Such systems are known. They have the advantage of being continuous Hot-rolled strip made from a continuously cast material is inexpensive because of a significant saving in energy alone This enables that in conventional methods and systems necessary facilities for reheating the slabs, Intermediate transport facilities and storage spaces are eliminated. The already cast cast strip shaped like a strip reduces the cross-section high deformation effort and high deformation energy can be dispensed with and allowed to wind up the cast strand immediately behind the strand casting machine to coils. This winding or reeling is therefore not necessary manoeuvrable because of the maximum casting speed at which the cast strand Continuous caster leaves much lower than the lowest possible Rolling speed of conventional roll stands.

Es ist deshalb durch die gattungsbildende DE 32 41 745 C2 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 Einrichtung verwendet, mit der relativ dicke Gußstränge gewickelt werden können. It is therefore proposed by the generic DE 32 41 745 C2 to wind the cast strand in a furnace without a thorn into a bundle and after implementation of the federal government, this must be dealt with discontinuously and to feed a rolling mill. For winding, a coil box is known Device used with the relatively thick cast strands are wound can.  

Die bekannte Anlage mit der Anordnung der Haspelstationen innerhalb des Ofens ist konstruktiv ungünstig, weil die Vorrichtungen zum Umsetzen des Bundes von der Aufwickelhaspelstation in die Abwickelhaspelstation im Heißteil des Ofens funktionieren müssen und eine Zwischenspeicherung nicht möglich ist.The known system with the arrangement of the reel stations within the The furnace is structurally unfavorable because the devices for moving the Bund from the take-up reel station to the take-up reel station in The hot part of the oven must work and temporary storage does not is possible.

Aufgabe der vorliegenden Erfindung ist, ausgehend von dem vorstehend be­ schriebenen Stand der Technik, die Anordnung der Aufwickelvorrichtung und Transportmittel 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.Object of the present invention, starting from the above be wrote prior art, the arrangement of the winding device and To improve transportation within the oven so that a problem-free Rewinding and unwinding of the casting tape and, if necessary, intermediate storage possible and that Implementation of the federal government is simplified.

Zur Lösung der Aufgabe schlägt die Erfindung vor, daß die Transportmittel für die Bunde schrittweise auf einer geschlossenen in einer vertikalen Ebene ver­ laufenden Umlaufbahn bewegbar sind.To achieve the object, the invention proposes that the means of transport for the bundles gradually on a closed in a vertical plane ver current orbit are movable.

Durch den Vorschlag der Erfindung wird im Prinzip ein senkecht stehendes Drehkreuz oder eine Drehscheibe geschaffen, auf der die Bunde bewegt werden.In principle, the proposal of the invention makes it a vertical one Turnstile or a turntable created on which the bundle moves will.

Während ein Bund in der Aufwickel-Haspelstation aus dem von der Stranggieß­ anlage kommenden Gußstrang gewickelt wird, kann in der versetzt angeordneten Abwickel-Haspelstation das zuvor umgesetzte Bund abgewickelt und dem Walzwerk zugeführt werden.While a bundle in the reel-up station from the continuous casting plant coming cast strand can be wrapped in the arranged unwinding reel station unwound the previously implemented bundle and fed to the rolling mill.

Eine Zwischenspeicherung zum Ausgleich der unterschiedlichen Geschwindig­ keiten von Stranggießanlage und Walzwerk ist nach einem anderen Merkmal der Erfindung dadurch denkbar, daß mehr als zwei Haspelstationen gleichmäßig verteilt auf der Umlaufbahn angeordnet sind.A temporary storage to compensate for the different speeds of the continuous caster and rolling mill has another characteristic the invention conceivable in that more than two reel stations are evenly distributed on the orbit.

Es empfiehlt sich nach einer Ausgestaltung der Erfindung, die Transport­ mittel auf einer Kreisbahn bewegbar anzuordnen, wobei es jedoch auch denkbar ist, andere in sich geschlossene Bewegungsbahnen vorzusehen.According to an embodiment of the invention, it is advisable to transport to be arranged movably on a circular path, but also  it is conceivable to provide other closed trajectories.

Die Erfindung ermöglicht in günstiger Weise, jeder Aufwickelstation einen angetriebenen Wickeldorn zuzuordnen. Damit besteht die Möglichkeit, von den kompliziert umzusetzenden dornlosen Haspeln mit Dorn überzugehen, was mindestens bei dünneren Gußstrangquerschnitten vorteilhaft ist. In diesem Fall sind die Dorne auf der geschlossenen Umlaufbahn bewegbar an einem gemeinsamen Träger angeordnet, der um eine zentrale Drehachse drehbar ist.The invention allows each winding station in a favorable manner assign driven winding mandrel. So there is the possibility of the thornless reels with thorn that are difficult to implement to transition, which is advantageous at least in the case of thinner cast strand cross sections is. In this case the mandrels are in closed orbit movably arranged on a common carrier, which is around a central The axis of rotation is rotatable.

In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Wickeldorne unabhängig voneinander angtrieben und die relativ zur Umlauf­ bahn der Haspelstationen feststehenden Antriebe mit den Wickeldornen lösbar gekuppelt sind. Da die Wickeldorne aufgrund der unterschiedlichen Geschwindigkeiten zum Aufhaspeln und Abhaspeln mit unterschiedlichen Antriebsgeschwindigkeiten arbeiten müssen, empfiehlt es sich, die Antriebe feststehen zu lassen, während die Wickeldorne schrittweise in die jeweilige Wickelposition verbracht werden. Deshalb sind die Antriebe erfindungsgemäß von den Wickeldornen ab- bzw. daran ankuppelbar.In a further embodiment of the invention it is provided that the Mandrels driven independently of each other and relative to the circulation of the reel stations, fixed drives can be detached with the winding mandrels are coupled. Because the mandrels due to the different Speeds for reeling and uncoiling with different Drive speeds must work, it is recommended to use the drives to let stand, while the mandrels gradually into each Winding position are spent. The drives are therefore according to the invention detachable from or coupled to the mandrels.

Sofern die Haspel- oder Walztemperatur nicht die 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 Einrich­ tungen können selbstverständlich entfallen, wenn die Temperatur des Ofens ein Walzen ohne Nacherwärmung ermöglicht bzw. die Temperatur des Gußstran­ ges der Haspeltemperatur entspricht.If the reel or roll temperature is not the required values has, is provided according to a further feature of the invention that before and / or a device for controlled heating of the Cast strand is arranged on reel or rolling temperature. Such furnishings tations can of course be omitted if the temperature of the furnace rolling without reheating or the temperature of the cast iron total corresponds to the reel temperature.

In einer besonders günstigen Ausgestaltung der Erfindung ist vorgesehen, daß die Transportmittel in dem einlaufseitigen Haspelofen eines Steckel­ walzwerkes angeordnet sind. Die Abwickelhaspelstation kann in bekannter Weise zum mehrfachen Auf- und Abhaspeln des in Reversierstichen gewalzten Bandes verwendet werden, also in der Art eines Steckelofens, wie er mit nur einer Haspelstation bekannt ist.In a particularly advantageous embodiment of the invention, that the means of transport in the inlet side reel furnace of a Steckel Rolling mill are arranged. The decoiler can in known Way to rewind and unwind the rolled in reversing stitches several times  Band are used, so in the manner of a plug-in oven, as with only one reel station is known.

Schließlich wird vorgeschlagen, daß den Transportmitteln in an sich bekannter Weise eine Querteilschere vor- und/oder Einrichtungen zum Ent­ zundern nachgeordnet sind. Die Querteilschere ist dann erforderlich, wenn das Gußstranggewicht größer als das Bundgewicht des in der Aufwickelhaspel­ station befindichen Bundes ist. Einrichtungen zum Entzundern sind in der Regel hinter dem Ofen erforderlich, um ein Einwalzen des Zunders im Walz­ werk zu verhindern.Finally, it is suggested that the means of transport in itself known way a cross-section scissors before and / or devices for Ent scale are subordinate. The cross cut shear is required if the cast strand weight is greater than the coil weight of the in the reel station located federal. Descaling facilities are in the Usually required behind the furnace to roll the scale in the roller prevent work.
