Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zur Warmbehandlung von Stahldraht, bei der der Draht nach seinem Austritt aus einer kontinuierlichen Drahtwalzstraße von einem Windungsleger auf einen Horizontalförderer aufgelegt, und auf diesem in der Form einer Reihe von aufeinanderfolgend überlappenden Windungen weitertransportiert, während des Transports oberflächenbehandelt, am Ende des Förderers von einer Windungssammelvorrichtung zu einem Drahtbund zusammengefaßt und einer Bundtransporteinrichtung übergeben wird.The invention relates to a device for the heat treatment of steel wire, in which the wire, after it emerges from a continuous wire rolling mill, is placed by a winding layer on a horizontal conveyor, and is further transported thereon in the form of a series of successively overlapping turns, surface-treated during transportation, at the end of the conveyor from a winding collecting device to a wire bundle and transferred to a coil transport device.
Mit einer solchen Einrichtung ist es zwar möglich, den Draht während seiner Auflage auf dem Horizontalförderer wärmezubehandeln oder auch zu kühlen, z. B. durch Aufbringen von geblasener Luft oder Aufsprühen von Kühlflüssigkeiten auf die Drahtwindungen. Es ist dabei auch bekannt, über den Horizontalförderer Wärmedämmabdeckungen zur Verstärkung der Wärmebehandlung und zur Verringerung der Wärmeverluste anzubringen.With such a device, it is possible to heat-treat or cool the wire while it is resting on the horizontal conveyor, e.g. B. by applying blown air or spraying coolants onto the wire windings. It is also known to apply thermal insulation covers to increase the heat treatment and to reduce the heat losses via the horizontal conveyor.
Die Wärmebehandlung von Walzdraht unter weitgehender Ausnutzung der im Draht nach seinem Austritt aus Drahtwalzstraße vorhandenen Walzhitze ist mit einer solchen Einrichtung nicht möglich; dies wird bei der sog. Haubenglühe dadurch erreicht, daß der Draht sofort nach seinem Austritt aus der Drahtwalzstraße zu einem Drahtbund gewickelt und der Drahtbund von einer Wärmedämmhaube abgedeckt wird, unter der er sich aus der mitgebrachten Walzhitze langsam abkühlt oder auch hier noch unter Wärmezufuhr gezielt aufgeheizt und dann abgekühlt wird, z. B. nach vorherigem Abnehmen der Wärmedämmhaube durch Eintauchen in ein Wasserbad.The heat treatment of wire rod with extensive use of the rolling heat present in the wire after its exit from the wire rolling mill is not possible with such a device; This is achieved with the so-called bell annealer in that the wire is wound into a wire bundle immediately after it emerges from the wire-rolling mill and the wire bundle is covered by a thermal insulation hood, under which it slowly cools down from the rolling heat brought in or also here, while still applying heat heated and then cooled, e.g. B. after removing the thermal insulation hood by immersing it in a water bath.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Einrichtung so zu verbessern, daß der aus der Drahtwalzstraße austretende Draht wahlweise einer der oben aufgezählten Behandlungsweisen unterworfen werden kann, ohne daß der Walzbetrieb unterbrochen werden müßte.The invention has for its object to improve the generic device so that the wire emerging from the wire rolling mill can optionally be subjected to one of the treatment methods listed above, without having to interrupt the rolling operation.
Diese Aufgabe wird durch eine, hinter dem Windungsleger in die Transportbahn des Horizontalförderers ein- und ausbringbare zweite Windungssammelvorrichtung gelöst, deren zugeordnete Bundtransporteinrichtung wahlweise betätigbare Übergabevorrichtungen für die Übergabe der Drahtbunde an Bundwärmeeinrichtungen bzw. Bundkühleinrichtungen aufweisen.This object is achieved by a second winding collecting device that can be inserted and removed behind the winding layer in the transport path of the horizontal conveyor, the associated coil transport device of which has selectively actuatable transfer devices for transferring the wire bundles to coil heating devices or coil cooling devices.
Dabei kann der Horizontalförderer hinter dem Windungsleger einen, quer aus der Transportbahn herausfahrbaren und durch die Windungssammelvorrichtung ersetzbaren Förderabschnitt aufweisen, und die Bundtransporteinrichtung kann aus einem Querförderer, für in die Windungssammelvorrichtung einzubringenden leeren und nach deren Beladung mit den jeweiligen Drahtbunden aus dieser auszubringenden Bundaufnahmepaletten besteht, wobei die Transportebene des Querförderers unterhalb einer, wahlweise betätigbaren Einrichtung zum Aufsetzen von Wärmedämmhauben auf die aus der Windungssammelvorrichtung ausgebrachten, mit Drahtbunden beladenen Bundaufnahmepaletten verläuft.The horizontal conveyor can have behind the winding layer a conveyor section that can be moved out of the transport path and can be replaced by the winding collecting device, and the coil transport device can consist of a transverse conveyor for empty coil pallets that are to be inserted into the winding collecting device and, after being loaded with the respective wire bundles, they have to be taken out of the coil receiving pallets. wherein the transport plane of the cross conveyor runs below an optionally operable device for placing thermal insulation hoods on the coil receiving pallets loaded with wire bundles and brought out of the winding collecting device.
Dem Querförderer kann in Transportrichtung hinter der Einrichtung zum Aufsetzung der Wärmedämmhauben eine Hubeinrichtung zum seitlichen Absetzen der Bundaufnahmepaletten mit den, von Wärmedämmhauben abgedeckten Drahtbunden in einen wärmegedämmten, abdeck- und beheizbaren Sammelspeicher zugeordnet sein.The cross conveyor can be assigned in the direction of transport behind the device for placing the thermal insulation hoods a lifting device for the lateral depositing of the bundle receiving pallets with the wire bundles covered by thermal insulation hoods in a thermally insulated, coverable and heatable collective store.
Dem Querförderer kann auch in Transportrichtung hinter der Einrichtung zum Aufsetzen der Wärmedämmhauben eine Hubeinrichtung zum seitlichen Absetzen und Eintauchen der Bundaufnahmepaletten mit den Drahtbunden in ein Wasserbad zugeordnet sein.The cross conveyor can also be assigned a lifting device for the lateral placement and immersion of the bundle receiving pallets with the wire bundles in a water bath behind the device for fitting the thermal insulation hoods in the transport direction.
Die Einrichtungen zum seitlichen Absetzen der Bundaufnahmepaletten in einen Sammelspeicher bzw. ein Wasserbad können zweckmäßig an der dem Windungsleger abgewandten Seite des Querförderers angeordnet sein und, ihnen zugeordnete Zwischenförderer, parallel zu dem Horizontalförderer verlaufend, jeweils vor, oberhalb eines gemeinsamen zweiten Querförderers angeordneten und Übergabevorrichtungen enden, die den Drahtbund an eine Weitertransporteinrichtung übergeben, und die zugehörige, leere Bundaufnahmepalette auf diesen zweiten Querförderer absetzt, der über einen weiteren Zwischenförderer mit dem ersten Querförderer transportverbunden ist.The devices for the lateral depositing of the bundle receiving pallets into a storage tank or a water bath can expediently be arranged on the side of the cross conveyor facing away from the winding layer and, associated with them intermediate conveyors, running parallel to the horizontal conveyor, in each case before, arranged above, and above a common second cross conveyor and transfer devices , which transfer the coil of wire to a further transport device, and places the associated empty coil receiving pallet on this second cross conveyor, which is connected to the first cross conveyor by a further intermediate conveyor.
Die erfindungsgemäße Einrichtung erlaubt es, wahlweise den aus der Drahtwalzstraße austretenden Draht, nachdem dieser in der Form von aufeinanderfolgenden überlappenden Windungen auf den Horizontalförderer aufgelegt worden ist, auf dem Förderer mittels Luft oder Sprühwasser wärmezubehandeln und dann in die, am Ende des Horizontalförderers angeordnete Windungssammelvorrichtung einzubringen und den, darin gebildeten Drahtbund abzutransportieren. Stattdessen kann aber der aus der Drahtwalzstraße austretende Draht auch in der direkt hinter dem Windungsleger in die Transportbahn des Horizontalförderers eingebrachten Bundsammelvorrichtungen zu einem Drahtbund gesammelt, auf eine Bundaufnahmepalette aufgebracht, von dem Querförderer unter die Einrichtung zum Aufsetzen von Wärmedämmhauben transportiert, entweder mit den Wärmedämmhauben abgedeckt der Hubeinrichtung zum seitlichen Absetzen der Bundaufnahmepalette in einen Drahtbund-Sammelspeicher oder der Hubeinrichtung zum seitlichen Absetzen der Bundaufnahmepaletten mit dem Drahtbund in ein Wasserbad zugeleitet werden.The device according to the invention allows the wire emerging from the wire rolling mill, after it has been placed in the form of successive overlapping turns on the horizontal conveyor, to be heat-treated on the conveyor by means of air or spray water and then to be introduced into the winding collecting device arranged at the end of the horizontal conveyor and to remove the bundle of wire formed therein. Instead, the wire emerging from the wire rolling mill can also be collected into a bundle of wires in the bundle collecting devices placed directly behind the winding layer in the transport path of the horizontal conveyor, applied to a bundle receiving pallet, transported by the cross conveyor under the device for placing thermal insulation hoods, either covered with the thermal insulation hoods the lifting device for the lateral depositing of the bundle receiving pallet into a bundle of wire bundles or the lifting device for the lateral depositing of the bundle receiving pallet with the bundle of wire into a water bath.
Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail with reference to the embodiment shown in the drawing.
Die Zeichnung gibt die Einrichtung in perspektivischer Darstellung wieder.The drawing shows the device in perspective.
Der aus der, nicht dargestellten kontinuierlichen Drahtwalzstraße in Richtung des Pfeils S ankommende Draht D durchläuft zunächst eine Vorkühleinrichtung V und gelangt dann in den Windungsleger WL, der den Draht D in ebenfalls nicht dargestellten, aufeinanderfolgend überlappenden Windungen auf den Horizontalförderer HF ablegt. Am Förderende des Horizontalförderers HF befindet sich eine Windungssammelvorrichtung WS 1 in der Form eines vertikalen Sammelschachtes. Wie in der Zeichnung dargestellt, ist der Horizontalförderer HF hinter dem Windungsleger WL dadurch unterbrochen, daß ein Horizontalfördererabschnitt HFA quer seitlich aus der Transportbahn herausgefahren und an seiner Stelle eine zweite Windungssammelvorrichtung WS 2 in die Transportbahn eingebracht wurde. Unterhalb des Horizontalförderers HF ist ein Querförderer QF 1 angeordnet, dessen Transportbahn quer zur Transportbahn des Horizontalförderers HF verläuft; er ist zur Aufnahme und zum Transport von Bundaufnahmepaletten 2 bestimmt, die hier einen vertikalen Sammeldorn aufweisen. Über dem Querförderer QF 1 ist parallel zum Horizontalförderer HF verlaufend, ein Zuförderer ZF für die Wärmedämmhauben 1 angeordnet. Am Ende dieses Zuförderers ZF, vor dem Querförderer QF 1 befindet sich eine Aufsetzeinrichtung 3 für das Aufsetzen der auf dem Querförderer QF 1 befindlichen Bundaufnahmepaletten 2 mit den Drahtbunden DB. Seitlich des Querförderers QF 1, und zwar auf der, dem Windungsleger WL abgewandten Seite befindet sich ein Zwischenförderer 4, der vor einem Tauchbad 5 endet. Diesem Zwischenförderer 4 ist eine, nicht dargestellte Hubeinrichtung zum Einbringen der Bundaufnahmepaletten 2 mit oder ohne aufgesetzten Wärmedämmhauben 1 und zu deren Ausbringen aus dem Tauchbad 5 zugeordnet. Weiter befindet sich ebenfalls auf dieser Seite des Querförderers QF1 ein Sammelspeicher 6 in Form einer Grube, die mit verfahrbaren Abdeckungen 7 verschlossen werden kann. Die auf dem Querförderer QF 1 befindlichen Bundaufnahmepaletten 2 mit den Drahtbunden und den, diese abdeckenden Wärmedämmhauben 1 können mit Hilfe einer, nicht dargestellten Hubeinrichtung in die Grube 6 eingesetzt und aus dieser herausgebracht, auf einen Quer-Zwischenförderer 8 abgesetzt werden. Parallel zu dem ersten Querförderer QF 1 ist ein zweiter Querförderer QF 2 angeordnet, dessen Transportbahn unterhalb des Horizontalförderers HF verläuft. Diesem zweiten Querförderer QF 2 sind in den Bereichen hinter dem Tauchbad 5 bzw. dem Sammelspeicher 6 nicht dargestellte Übernahmeeinrichtungen für die aus dem Tauchbad 5 bzw. dem Sammelspeicher 6 herausgebrachten Bundaufnahmepaletten 2 mit den Drahtbunden DB und ggfs. den Wärmedämmhauben 1 sowie Bundübergabevorrichtungen 9 zugeordnet. Diese Bundübergabevorrichtungen 9 heben die Drahtbunde DB von den Bundaufnahmepaletten 2 ab; ihnen sind Hakenförderer 10 nachgeordnet. Der Querförderer QF 2 endet in einem weiteren Querförderer QF 3 der unter Zwischenschaltung einer Hubeinrichtung 11 mit dem ersten Querförderer QF 1 verbunden ist.The wire D arriving from the continuous wire rolling mill (not shown) in the direction of arrow S first passes through a pre-cooling device V and then passes into the winding layer WL, which deposits the wire D on the horizontal conveyor HF in successively overlapping turns, also not shown. At the end of the horizontal conveyor HF there is a winding collecting device WS 1 in the form of a vertical collecting shaft. As shown in the drawing, the horizontal conveyor HF behind the winding layer WL is interrupted by the fact that a horizontal conveyor section HFA is moved laterally out of the transport path and a second winding
Beim Betrieb der Einrichtung zur Wärmebehandlung des Drahtes während des Transportes auf dem Horizontalförderer HF bspw. durch Beaufschlagen mit, von unterhalb des Horizontalförderers HF angeordneten Gebläsen 12 erzeugter Luft werden die so behandelten Windungen in der Windungsammelvorrichtung WS 1 zu einem Drahtbund DB gesammelt, der aus dieser dem nachgeordneten Hakenförderer 10 übergeben wird. Der Horizontalfördererabschnitt HFA ist bei dieser Betriebsweise aus der, in der Zeichnung dargestellten Position in, nicht dargestellter Weise in die Transportbahn des Horizontalförderers HF eingeschoben worden.During operation of the device for heat treatment of the wire during transport on the horizontal conveyor HF, for example by applying air generated by
Soll der, aus der Drahtwalzstraße D kommende Draht D als Drahtbund wärmebehandelt werden, dann wird, wie dargestellt, der Horizontalfördererabschnitt HFA aus der Transportbahn des Horizontalförderers HF seitlich herausgefahren und an seine Stelle die Windungssammelvorrichtung WS 2 in die Transportbahn des Horizontalförderers HF eingefahren. Die vom Windungsleger WL auf den Horizontalförderer HF aufgelegten Windungen werden dann in dieser Windungssammelvorrichtung WS 2 zu einem Drahtbund DB auf der, in der Windungssammelvorrichtung WS 2 befindlichen Bundaufnahmepalette 2 gesammelt und durch den Querförderer QF 1 aus dieser heraus in die ebenfalls dargestellte Position vor dem Zwischenförderer 4 gebracht und dort mit Hilfe der Aufsetzeinrichtung 3 mit einer Wärmedämmhaube 1 abgedeckt. Die Bunde DB können dann entweder aus dieser Position heraus über den Zwischenförderer 4 in das Tauchbad 5 eingebracht und anschließend über die Bandübergabevorrichtung 9 auf den Hakenförderer 10 aufgebracht werden oder auf dem Querförderer QF 1 vor den Sammelspeicher 6 positioniert und mit Hilfe der, nicht dargestellten Hubeinrichtung in den Sammelspeicher 6 eingesetzt und nach Vollendung der Wärmebehandlung aus diesen über den Quer-Zwischenförderer 8 der Bundübergabevorrichtung 9 zugeführt und von dieser dem Hakenförderer 10 zugeführt werden. In beiden Fällen werden die in der Bandübergabevorrichtung 9 von den Bundaufnahmepaletten 2 und dem Drahtbund DB abgenommenen Wärmedämmhauben 1 mit Hilfe des zweiten Querförderers QF 2 und des weiteren Zwischenförderers QF 3 dem Querförderer QF 1 zur weiteren Verwendung in der Windungssammelvorrichtung WS 2 zugeführt.If the wire D coming from the wire-rolling mill D is to be heat-treated as a bundle of wires, then, as shown, the horizontal conveyor section HFA is moved laterally out of the transport path of the horizontal conveyor HF and the winding
