Description

Die Erfindung betrifft ein Stab- und Drahtwalzwerk mit einer zugeordneten Kühlbettlinie für Stäbe, einer Drehkorbhaspellinie für zu Coils gewickelte Stäbe und einer Drahtlinie mit einem Schlingenleger und Windungssammler für Draht mit nachgeordneten Warmhalteöfen für thermische Nachbehandlungen des das Walzwerk verlassenden Einsatzmaterials.The invention relates to a rod and wire rolling mill with an associated Cooling bed line for bars, a rotating basket reel line for rods wound into coils and a wire line with a loop layer and winding collectors for wire with downstream heating furnaces for thermal post-treatment of the feed material leaving the rolling mill.

Derartige Stab- und Drahtwalzwerke sind bekannt. Hier werden entweder Stäbe gewalzt, geschnitten, gekühlt und gebündelt oder gewalzte Stäbe in Drehkorbhaspeln gewickelt, gekühlt und gebündelt oder aber Draht in Windungen gelegt, gekühlt zu Drahtbunden gesammelt und anschließend gebunden. Für die meisten zu verarbeitenden Stahlqualitäten lassen sich derartige Stab- und Drahtstraßen nutzen. Werden jedoch z.B. Kalt-Arbeitsstähle oder Schnellstähle gewalzt und den entsprechenden Linien zugeführt, so müssen diese im Gegensatz zu anderen Verfahren ohne thermische Zwischen- oder Nachbehandlung, wie z.B. dem Kühlen isothermisch über einen längeren Zeitraum bis zum Erreichen eines gewünschten Materialgefüges bzw. bis zum Erreichen gewünschter Materialeigenschaften umwandeln.Rod and wire rolling mills of this type are known. Here either Rolled, cut, chilled and bundled or rolled bars Bars wrapped in rotary basket reels, cooled and bundled or else Wire laid in coils, collected into wire bundles and cooled then bound. For most steel grades to be processed such rod and wire lines can be used. Become however e.g. Cold-work steel or high-speed steel rolled and the appropriate lines fed, so these must be in contrast to other processes without thermal intermediate or aftertreatment, such as. cooling isothermally over a longer period of time to achieve a desired material structure or until it is reached convert desired material properties.

Dazu wurden bereits einzelne Linien, d.h. entweder Drahtlinien oder aber Stablinien vorgeschlagen, bei denen anstelle der Kühlstrecken Ausgleichsöfen vorgesehen sind. Es wurde auch schon vorgeschlagen, parallel zur Kühlstrecke einen entsprechenden Ausgleichsofen vorzusehen, um das Material, welches der isothermischen Behandlung zugeführt werden muß, aus der Linie auszuschleusen. In kombinierten Stab- und Drahtwalzwerken konnte Walzgut, welches einer isothermischen Nachbehandlung über längere Zeiträume zugeführt werden muß, bisher nicht gewalzt werden.Individual lines, i.e. either wire lines or but suggested rod lines where instead of the cooling sections Compensation ovens are provided. It has also been suggested to provide a corresponding compensating furnace parallel to the cooling section, to the material that is the isothermal treatment must be fed out of the line. In combined Bar and wire rolling mills could roll, which is an isothermal Aftertreatment must be administered over longer periods of time, have not been rolled so far.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gattungsgemäßes Stab- und Drahtwalzwerk so weiterzubilden, daß neben den normalen Stahlqualitäten auch Stähle gewalzt werden können, die über einen längeren Zeitraum isothermisch behandelt werden müssen, die einen geringen Platz beanspruchen und kostengünstig zu erstellen sind.The invention is therefore based on the object of a generic Rod and wire rolling mill so that in addition to the normal Steel grades can also be rolled over a steel longer periods of time need to be treated isothermally take up little space and are inexpensive to produce.

Dazu wird vorgeschlagen, daß die Kühllinie, die Drehkorbhaspellinie und die Drahtlinie über Transporteinrichtungen mit einem gemeinsamen Warmhalteofen verbunden sind.It is proposed that the cooling line, the rotary basket reel line and the wire line over transportation facilities with a common Holding oven are connected.

Damit wird erreicht, daß neben den üblichen Stahlqualitäten auch solche Stahlqualitäten zu Stäben bzw. zu Draht gewalzt werden können, die einer langen isothermischen Behandlung nach dem Walzvorgang bedürfen. Die üblichen Stahlqualitäten verlassen die Linie nach entsprechender Kühlung und anschließender Bündelung, während z.B. Kaltarbeitsstahl oder Schnellstahl mittels der Transporteinrichtung zum Warmhalteofen verbracht werden.This ensures that in addition to the usual steel qualities such steel grades are rolled into bars or wire can undergo a long isothermal treatment after the rolling process need. The usual steel grades leave the line appropriate cooling and subsequent bundling, e.g. Cold work steel or high speed steel by means of the transport device be brought to the holding furnace.

Es hat sich als vorteilhaft erwiesen, daß die Transporteinrichtung Stabsammelkästen, Drehkorbhaspelcoil-Paletten und Drahtcoil-Dornpaletten aufweist, und daß in der Kühlbettlinie, der Drehkorbhaspellinie und der Drahtlinie Übergabestationen vorgesehen sind, mittels derer das Walzgut an die Stabsammelkästen, Drehkorbhaspelcoil-Paletten und Drahtcoil-Dornpaletten übergebbar und über diese dem Warmhalteofen zuführbar ist. Die Übergabestation gewährleistet, daß das Stabmaterial bzw. der Draht aus der entsprechenden Linie herausgenommen und über die Stabsammelkästen, Drehkorbhaspelcoil-Paletten und Drahtcoil-Dornpaletten dem Warmhalteofen zugeführt werden können. It has proven advantageous that the transport device Rod collection boxes, rotary basket reel coil pallets and wire coil mandrel pallets has, and that in the cooling bed line, the rotary basket reel line and the wire line transfer stations are provided by means of or the rolling stock to the rod collection boxes, rotary basket reel coil pallets and wire coil mandrel pallets can be transferred and via this the Holding oven can be fed. The transfer station ensures that the rod material or the wire is removed from the corresponding line and over the rod collection boxes, rotary basket reel coil pallets and wire coil mandrel pallets fed to the holding furnace can be.

Um die auszuschleusenden Stäbe bzw. den auszuschleusenden Draht nicht zu stark abzukühlen hat es sich bewährt, daß die Übergabestationen in Transportrichtung des Walzgutes vor den Kühlbetten bzw. der Längstransportvorrichtung der jeweiligen Linien in der Nähe des Warmhalteofens angeordnet sind.To the rods or wire to be removed It has proven useful not to cool down too much that the transfer stations in the direction of transport of the rolling stock in front of the cooling beds or the longitudinal conveyor of the respective lines near the Holding oven are arranged.

Sind der Transporteinrichtung Isoliertunnel-Speicher zugeordnet, so lassen sich die Stabsammelkästen sowie Paletten im Warmhalteofen aufheizen und in den Speichern auf Abruf abstellen. Dort stehen damit für das in den Warmhalteofen einzubringende Walzgut stets geheizte Stabsammelkästen bzw. Paletten zur Verfügung. Die Verwendung aufgeheizter Stabsammelkästen und Paletten ist von besonderer Bedeutung, um zu verhindern, daß das Walzgut bei Berührung mit eventuellen kalten Stellen der Stabsammelkästen bzw. Paletten selbst partiell zu stark gekühlt wird und an den Berührungspunkten kalte Stellen bekommen, die gegebenenfalls später nicht die gewünschte Gefügestruktur aufweisen. Dadurch daß die Stabsammelkästen und Paletten aufgeheizt und in aufgeheiztem Zustand gespeichert werden können, wird erreicht, daß das Walzgut auch beim Beladen der Kästen bzw. Paletten gleichmäßig temperiert bleibt.If insulated tunnel storage is assigned to the transport device, so the rod collection boxes and pallets can be kept in the holding furnace heat up and store on demand in the storage tanks. Stand there thus always for the rolling stock to be introduced into the holding furnace heated rod collection boxes or pallets available. The usage heated rod collection boxes and pallets is special Significance to prevent the rolling stock from touching any cold spots on the rod collection boxes or pallets themselves is partially cooled too much and cold at the points of contact Get jobs that may not be the one you want later Show structure. Because the rod collection boxes and Pallets are heated and stored in the heated state can, it is achieved that the rolling stock even when loading the boxes or pallets remains at an even temperature.

Weist die Transporteinrichtung umlaufende Rollgänge auf, in denen der Warmhalteofen eingeschlossen ist, so kann es beim An- und Abtransport der Stabsammelkästen, Drehkorbhaspelcoil-Paletten und Drahtcoil-Dornpaletten zu keinen Staus bzw. Behinderungen kommen.Has the transport device revolving roller tables in which the warming furnace is included, so it can when starting and Removal of the rod collection boxes, rotary basket reel coil pallets and Wire coil mandrel pallets do not cause any traffic jams or obstructions.

Zusätzlich, aber auch anstelle der Isoliertunnel-Speicher können die Rollgänge als wärmeisolierte Rollgänge ausgebildet sein, um einerseits auf den Transportwegen den Temperaturverlust möglichst klein zu halten, aber andererseits auch die Rollgänge als Speicher-rollgänge nutzen zu können.In addition, but also instead of the insulated tunnel storage can the roller tables can be designed as heat-insulated roller tables on the one hand, the temperature loss as possible on the transport routes keep it small, but also the roller tables as storage roller tables to be able to use.

Am Ende der Längstransportvorrichtung 19 ist ein Kippstuhl 20 vorgesehen, mittels dessen die Stabbunde kippbar und an eine Hakenbahn 21 übergebbar sind, um von dieser zur Bundbindepresse 22 verbracht zu werden.The rotary basket reel line 7 has drivers 16, 16 'and rotary basket reel 17, 17 '. One is connected to the rotary basket reel 17, 17 ' Transfer station 18, by means of which the rods wound into coils of the two rotary basket reels 17, 17 'onto a longitudinal transport device 19 are transferable. At the end of the longitudinal transport device 19 a tilting chair 20 is provided, by means of which the bundles of rods can be tilted and can be transferred to a hook track 21 in order from this to the binding press 22 to be spent.

In der Drahtlinie 8 ist der Schlingenleger 9, das Stelmor-Kühlbett 10, der Windungssammler 11 sowie ein Kippstuhl 23 gezeigt, der ebenfalls mit der Hakenbahn 21 und der Bundbindepresse 22 zusammenarbeitet. Der Kühlbettlinie 6 ist eine Übergabestation 24 zur Übergabe der Stäbe an auf einer Transporteinrichtung 25 verfahrbaren Stabsammelkasten 27 zugeordnet, wobei eine Schere 26 die Stäbe auf Längen zuzuschneiden vermag, welche den Innenabmessungen der Stabsammelkästen 27 entsprechen. Die Übergabestation 18 in der Drehkorbhaspellinie 7 ist ebenfalls in der Lage, die zu Bunden gewickelten Stäbe an Paletten 28 der Transporteinrichtung 25 abzugeben. Über eine Übergabestation 29 in der Drahtlinie 8 ist der zu Windungen gelegte Draht auf einer Dornpalette 30 sammelbar und an die Transporteinrichtung 25 übergebbar.In the wire line 8 is the loop layer 9, the Stelmor cooling bed 10, the winding collector 11 and a tilting chair 23 shown also cooperates with the hook track 21 and the binding press 22. The cooling bed line 6 is a transfer station 24 for transferring the Rods on rod collecting box movable on a transport device 25 27 assigned, with scissors 26 the rods to lengths is able to cut the inner dimensions of the rod collection boxes 27 correspond. The transfer station 18 in the rotary basket reel line 7 is also capable of the rods wound into bundles to be delivered to pallets 28 of the transport device 25. Over a Transfer station 29 in the wire line 8 is the winding Wire can be collected on a mandrel pallet 30 and sent to the transport device 25 transferable.

Die Transporteinrichtung 25 besteht aus umlaufenden Rollgängen 31, auf denen die Stabsammelkästen 27, die Paletten 28 und die Dornpaletten 30 verfahrbar sind. Die Transporteinrichtung 25 dient dazu, die Stäbe bzw. Stabbunde oder Drahtbunde, aber auch die leeren Stabsammelkästen 27, Paletten 28 und Dornpaletten 30 einem Warmhalteofen 32 zuzuführen.The transport device 25 consists of rotating roller tables 31, on which the rod collection boxes 27, the pallets 28 and the mandrel pallets 30 are movable. The transport device 25 serves to the rods or bundles of rods or wire bundles, but also the empty ones Rod collection boxes 27, pallets 28 and mandrel pallets 30 a holding furnace 32 feed.

Neben dem als Speicher-Rollgang 31 mit entsprechender Wärmeisolierung ausgebildeten Rollgang 31 ist der Transporteinrichtung 25 ein Isoliertunnel-Speicher 33 zugeordnet, der zusätzlich zu dem wärmegedämmten Speicher-Rollgang 31, Stabsammelkästen 27 aufzunehmen vermag.In addition to that as a storage roller table 31 with appropriate thermal insulation trained roller table 31 is the transport device 25 Insulated tunnel memory 33 associated with that in addition to the insulated Storage roller table 31 to record rod collection boxes 27 can

In der Regel wird die in den Fig. 1 und 2 gezeigte Walzanlage zum Walzen, Teilen, Kühlen und Bündeln üblicher Stahlqualitäten benutzt. Sollten jedoch Stahlqualitäten gewalzt werden, die einer langen isothermischen Behandlung bedürfen, so werden z.B. Stäbe mittels der Übergabestation 24 in zuvor im Warmhalteofen 32 aufgeheizte, über die Rollgänge 31 zum Isoliertunnel-Speicher 33 verbrachte und von diesem zur Übergabestation 24 beförderte Stab-Sammelkästen 27 abgelegt.
