Description

Vorrichtung zum Vergüten von Walzgut mit großer LängeDevice for tempering rolled material with a long length
Die Erfindung betrifft eine Einrichtung zum Härten von Walzgut mit großer Längserstreckung bei hohem Durchsatz. Genauer definiert betrifft die Erfindung eine Vorrichtung zum thermischen Vergüten von zumindest Teilen des Querschnittes über die Längserstreckung von in Sequenz gefertigtem profilierten Walzgut aus der Walzhitze, insbesondere zum Härten zumindest des Kopfes von Schienen mit einer Länge von größer als 50 m und nachfolgender Abkühlung auf Raumtemperatur, bestehend im wesentlichen aus einem Rollgang, einem Mittel zur achsfluchtenden Ausrichtung des Walzgutes, einem Transportmittel mit einer Auflage für das Walzgut zur Querverbringung desselben, einer Härteeinrichtung mit einer Manipulationsanordnung und einem Kühlbett.The invention relates to a device for hardening rolling stock with a large longitudinal extension at a high throughput. More precisely defined, the invention relates to a device for the thermal annealing of at least parts of the cross-section over the longitudinal extent of profiled rolling stock produced in sequence from the rolling heat, in particular for hardening at least the head of rails with a length of more than 50 m and subsequent cooling to room temperature, consisting essentially of a roller table, a means for axially aligned alignment of the rolling stock, a means of transport with a support for the rolling stock for transverse placement thereof, a hardening device with a manipulation arrangement and a cooling bed.
Zur Verbesserung der Materialeigenschaften wird ein Walzgut zumeist einer thermischen Vergütebehandlung, welche in vorteilhafter Weise unter Nutzung der Walzhitze erfolgt, unterworfen. Diese Vergütung, die im wesentlichen eine Erhöhung der mechanischen Werkstoffeigenschaften, wie Härte, Abriebfestigkeit und dgl. bewirkt, kann über den Gesamtquerschnitt oder wie bei einer Fahrschiene üblich, nur über Teilbereiche desselben durchgeführt werden. Dabei wird das im austeniitischen Gefügezustand befindliche Walzgut oder Teilbereiche des Querschnittes desselben über die gesamte Länge in ein Kühlmedium eingetaucht und derart eine Gefügeumwandlung in gewünschter Art erreicht.To improve the material properties, a rolling stock is usually subjected to a thermal heat treatment, which is advantageously carried out using the rolling heat. This tempering, which essentially increases the mechanical properties of the material, such as hardness, abrasion resistance and the like, can be carried out over the entire cross section or, as is customary in the case of a running rail, only over partial areas of the same. The rolled material or parts of its cross-section in the austenitic structural state are immersed in a cooling medium over the entire length, and a structural transformation in the desired manner is achieved in this way.
Einrichtungen zur Durchführung von derartigen Vergütungsverfahren sind bekannt (EP-0441766 B1) und haben sich im Hinblick auf eine Verbesserung der Gebrauchseigenschaften von Eisenbahnschienen durchaus bewährt.Devices for carrying out such remuneration processes are known (EP-0441766 B1) and have proven themselves with regard to improving the performance properties of railroad tracks.
Je nach Walzendtemperatur sowie je nach spezifischer Masse bzw. Masse je Längeneinheit des Walzgutes erfordert dessen thermisches Vergüten eine entsprechende Tauchzeit oder Verweilzeit in der Kühlflüssigkeit, so daß der Durchsatz durch die Vergütevorrichtung begrenzt ist. Mit anderen Worten: Der maximal mögliche Durchsatz durch eine Tauch-Vergüteanlage mit einem Abkühlbecken limitiert die Leistung der vorgeordneten Walzeinrichtung.Depending on the final roll temperature and on the specific mass or mass per unit length of the rolling stock, its thermal tempering requires a corresponding immersion time or dwell time in the cooling liquid, so that the throughput is limited by the tempering device. In other words: the maximum possible throughput through a diving compensation system with one Cooling basin limits the performance of the upstream rolling device.
Modere Profilwalzstraßen mit vorgeordneten Wärmeöfen insbesondere für Strangguß-Vormaterial verfügen zumeist über mögliche Walzleistungen, die größer sind als der Durchsatz von bekannten Tauch-Vergüteanlagen, so daß bei einer sequentiellen Herstellung von gehärteten Schienen die Walzleistung zurückgenommen werden muß.Modern profile rolling mills with upstream heating furnaces, in particular for continuous casting primary material, mostly have possible rolling capacities which are greater than the throughput of known immersion tempering systems, so that the rolling capacity must be reduced in the sequential production of hardened rails.
Zur Vermeidung dieses insbesondere wirtschaftlichen Nachteiles wurde schon vorgeschlagen, das Walzgut im Durchlauf durch eine mit Sprühmittel versehene Kühlstrecke zu vergüten. Dieses Durchlaufverfahren erfordert jedoch große Baulängen der Einrichtung und erbringt zumeist nicht eine geforderte Materialqualität des Walzgutes.In order to avoid this, in particular, economic disadvantage, it has already been proposed to temper the rolling stock in a pass through a cooling section provided with spraying agent. However, this continuous process requires large installation lengths of the device and mostly does not produce the required material quality of the rolling stock.
Die Erfindung zielt nun darauf ab, die Mängel und insbesondere die wirtschaftlichen Nachteile von bekannten thermischen Behandlungseinrichtungen für Walzgut der eingangs genannten Art zu vermeiden und eine Vorrichtung zu schaffen, welche eine hohe Qualität und gute Gebrauchseigenschaften des durchgesetzten Walzgutes sicherstellt sowie eine große Leistung besitzt und es ermöglicht, in Sequenz gefertigtes Stabmaterial, insbesondere Schienen mit Längen über 50 m, aus Walzstraßen mit hoher Leistung unter Nutzung der Walzhitze zu behandeln und thermisch zu vergüten.The invention now aims to avoid the shortcomings and, in particular, the economic disadvantages of known thermal treatment devices for rolling stock of the type mentioned at the outset and to provide a device which ensures high quality and good usage properties of the rolling stock which is being passed through, and which has a high performance and it makes it possible to treat rod material manufactured in sequence, in particular rails with lengths over 50 m, from rolling mills with high output using the heat of the roll and to heat treat them.
Dieses Ziel wird bei einer gattungsgemäßen Vorrichtung dadurch erreicht, daß der Rollgang eine Einrichtung zur Positionierung des in mindestens einem Querschnittsbereich aufliegend zugeförderten Walzgutes in Längsrichtung und ein zugeordnetes Ausrichtmittel aufweist, daß die Härteeinrichtung aus mindestens zwei nebeneinander mit in deren Längsrichtung im wesentlichen parallel zum Ausrichtmittel angeordneten Flussigkeitskuhleinrichtungen mit Manipulatoren für eine Bewegung des Walzgutes gebildet ist, daß neben den und parallel zur Längserstreckung der Flussigkuhleinrichtungen sich der Auflegebereich vom Kühlbett befindet und daß das Quertransportmittel mindestens zwei simultan zwischen den Rollgangrollen bewegbare Tragarme mit jeweils endenseitig daran angeordneten Walzgutauflagen besitzt, diese Auflagen an den Tragarmen in Querrichtung von der Richtposition im Bereich des Rollganges bis in den Auflegebereich des Kühlbettes verfahrbar, absenkbar und derart anhebbar sind, daß ausschließlich die Auflagen die Förderebene des Rollganges bzw. die Rollgangs'bberkante überragen.This goal is achieved in a generic device in that the roller table has a device for positioning the rolled material lying in at least one cross-sectional area lying in the longitudinal direction and an associated alignment means that the hardening device is arranged from at least two next to each other with in the longitudinal direction substantially parallel to the alignment means Liquid cow devices with manipulators for moving the rolling stock is formed in such a way that, in addition to and parallel to the longitudinal extent of the liquid cow devices, the laying area of the cooling bed is located and that the transverse transport means at least two simultaneously has movable arms between the roller table rollers, each with rolling stock supports arranged on the end, these supports can be moved, lowered and raised in the transverse direction on the support arms in the transverse direction from the straightening position in the area of the roller table to the support area of the cooling bed, so that only the supports the conveying plane of the roller table or protrude over the upper edge of the roller table.
Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, daß auf einfache Weise mit der Vorrichtung in Sequenz im Quertransportbereich des Rollganges Walzgut mit hoher Genauigkeit positionierbar und achsial richtbar ist, wobei mittels der Walzgutauflagen des Quertransportmittels gleichzeitig, also ohne Beeintächtigung der Einstellung und des achsialen Richtvorganges, ein vorhergehend gerichtetes und bereitgestelltes Walzgut in die Ablagebereiche der Kühleinrichtungen oder von diesen in den Auflagebereich vom Kühlbett oder vom Rollgang direkt auf das Kühlbett verbracht werden kann. Dabei ist es wichtig, daß lediglich die Walzgutauflagen der zwischen den Rollen bewegbaren Tragarame des Quertransportmittels über das obere Niveau der Rollgangrollen bzw. deren Förderungsebene anhebbar sind. Bei dieser Ausbildungsform der Vorrichtung ist es möglich, mindestens zwei Härteeinrichtungen an einer Seite des Rollganges anzuordnen, so daß lediglich einseitig ein Kühlbett vorzusehen ist, was wirtschaftliche Vorteile erbringt. Ein am Rollgang positioniertes und achsfluchtend gerichtetes Walzgut kann mittels der Auflagen der Tragarme von diesem abgehoben und beispielsweise in einen Ablagebereich einer Flüssigkeits-Kühleinrichtung, die als Manipulator ausgebildet ist, abgelegt werden. Danach ist das Quertransportmittel freigesetzt für weitere Walzgutquertransporte, wobei der Manipulator alleine und selbsttätig das abgelegte Walzgut in seiner Querschnittslage einrichten, in das Kühlmedium zumindest teilweise einbringen, ausheben und für einen Transport zumThe advantages achieved by the invention are, in particular, that rolling stock can be positioned with high accuracy and axially straightened in a simple manner with the device in sequence in the transverse transport region of the roller table, with the rolling stock supports of the transverse transport means simultaneously, i.e. without impairing the setting and the axial straightening process , a previously directed and provided rolling stock can be brought into the storage areas of the cooling devices or from these into the support area from the cooling bed or from the roller table directly onto the cooling bed. It is important that only the rolling stock supports of the supporting frame of the transverse transport means movable between the rollers can be raised above the upper level of the roller table rollers or their conveying plane. In this embodiment of the device, it is possible to arrange at least two hardening devices on one side of the roller table, so that a cooling bed is only to be provided on one side, which brings economic advantages. A rolling stock positioned on the roller table and aligned in line with the axis can be lifted off the support arms by the supports and placed, for example, in a storage area of a liquid cooling device, which is designed as a manipulator. Thereafter, the transverse transport means is released for further transverse rolling material transports, the manipulator setting up the deposited rolled material alone and automatically in its cross-sectional position, at least partially introducing it into the cooling medium, lifting it out and transporting it to the
Kühlbett bereitstellen kann. Diese erfindungswesentliche Trennung von Quertransport des Walzgutes auch über belegte Kühleinrichtungen hinweg mit letztlich einer Ablage am Kühlbett und ein genaues Einsetzen des Walzgutes in das Kühlmedium verbessert die Genauigkeit der Manipulation sowie der Abkühlbehandlung und führt zuverlässig zu gehärteten Walzprodukten mit konstant hoher Güte. In vorteilhafter und wirtschaftlicher Weise ist die Leistung bzw. der Durchsatz der Vorrichtung bei Verwendung von zwei Härteeinrichtungen nebeneinander etwa verdoppelt.Can provide cooling bed. This separation of transverse transport of the rolling stock, which is essential to the invention, even over occupied cooling devices with ultimately a deposit on the cooling bed and an exact insertion of the rolling stock into the cooling medium improves the accuracy of the manipulation and the cooling treatment and reliably leads to hardened rolled products with constant high quality. In an advantageous and economical manner, the performance or throughput of the device is approximately doubled when two hardening devices are used next to one another.
Wenn die Vorrichtung für ein Walzgut mit der Form einer Fahr- oder Eisenbahnschiene, welche in zwei Querschnittsbereichen am Rollgang aufliegt, vorgesehen ist und die Positioniereinrichtung als elektronisch steuerbares Mittel ausgebildet ist und/oder ein Ausrichtlineal oder einen Queranschlag aufweist, kann in günstiger Weise die Verweilzeit der Schiene am Rollgang verkürzt, die Temperaturführung verbessert und gegebenenfalls die Anlagenleistung erhöht werden. Weiers ist diese Lage besonders gut für eine sogenannte " Kopf unten" Senkrechtstellung der Schiene mittels der Manipulatoren geeignet.If the device is intended for rolling stock in the form of a running or railroad track, which rests in two cross-sectional areas on the roller table, and the positioning device is designed as an electronically controllable means and / or has an alignment ruler or a transverse stop, the dwell time can be reduced in a favorable manner the track on the roller table is shortened, the temperature control is improved and the system output is increased if necessary. This position is particularly well suited to Weiers for a so-called "head down" vertical position of the rail by means of the manipulators.
Wenn, wie bei einer Ausgestaltung der Erfindung vorgesehen sein kann, die Flüssigkkühleinrichtungen als Tauchbecken ausgebildet sind, die bodenseitig und gegebenenfalls seitwärts wirksame, horizontal und vertikal ausgerichtete Anschläge zur Nivellierung und Ausrichtung des Walzgutes aufweisen, kann insbesondere bei einer Abkühlung von Teilen des Querschnittes einer Schiene eine über deren Länge höchst konstante Abkühlung und Härteverteilung erreicht werden, was eine Gütesicherung des Erzeugnisses fördert.If, as can be provided in one embodiment of the invention, the liquid cooling devices are designed as plunge pools which have horizontally and vertically oriented stops for leveling and aligning the rolling stock on the bottom side and optionally laterally, in particular when parts of the cross section of a rail are cooled down a very constant cooling and hardness distribution can be achieved over its length, which promotes quality assurance of the product.
Vorteilhaft für konstante und gute Gebrauchseigenschaften ist, wenn in der Vorrichtung Niederhaltemittel für das Walzgut, insbesondere für eine Schiene, vorgesehen sind, mit welchen Mitteln das Walzgut/die Schiene während des Abkühlens an die Nivellierungsanschläge im Tauchbecken andrückbar ist, weil damit eine durch die Abkühlung verursachte Krümmung wirksam verhindert und die jeweilige örtliche Kühlung der Oberfläche vollkommen gleich gehalten werden kann.It is advantageous for constant and good usage properties if hold-down means for the rolling stock, in particular for a rail, are provided in the device, with which means the rolling stock / rail can be pressed against the leveling stops in the plunge pool during cooling, because this results in cooling caused curvature effectively prevented and the respective local cooling of the surface can be kept completely the same.
Besondere wirtschaftliche Vorteile sind bei einer Verwendung der oben beschriebenen Vorrichtung zum Härten zumindest des Kopfes von Schienen mit einer Länge von größer als 50 m und nachfolgender Abkühlung auf Raumtemperatur bei einer die Zuförderfrequenz überschreitenden Durchlaufzeit einer Schiene durch die Härteanlage gegeben, weil mit vergleichsweise niedrigen Anlagenkosten große Leistungssteigerungen möglich sind.Particular economic advantages are when using the above-described device for hardening at least the head of rails with a length of more than 50 m and subsequent cooling to room temperature with a throughput time exceeding the feed frequency given a rail through the hardening plant because large increases in performance are possible with comparatively low plant costs.

In der beispielhaften schematischen Darstellung ist in einer der Flussigkeitskuhleinrichtungen 31 der Kopf der Schiene S in eine Kühlflüssigkeit 315 eingetaucht gezeigt. Durch Niederhaltemittel 314 und Nivellierungsanschläge 313 ist dielSchiene in einem Tauchbecken 312 derart positionierbar, daß exakt nur eine forcierte Kopfkühlung derselben erfolgt. Es ist jedoch auch möglich, durch tiefer unter die Oberfläche einer Kühlflüssigkeit 315 gelegte Anschläge 313 den gesamten Querschnitt der Schiene forciert zu kühlen. Eine zweite Flüssigkühleinrichtung 32 steht in Bereitschaft.52 Rolled goods support 1 shows a device according to the invention with a hardening device 3 consisting of two liquid cooling devices 31 and 32, which are arranged between a roller table 1 and a cooling bed 4. In the exemplary schematic illustration, the head of the rail S is immersed in a cooling liquid 315 in one of the liquid cooling devices 31. The l rail can be positioned in a plunge pool 312 by hold-down means 314 and leveling stops 313 in such a way that the head is only forced to cool. However, it is also possible to force the entire cross section of the rail to be forced by means of stops 313 placed deeper below the surface of a cooling liquid 315. A second liquid cooling device 32 is on standby.
Wie weiter Fig. 1 zeigt, ist von einer Walzenstraße ( nicht dargestellt) kommend eine Schiene S am Rollgang 1 positioniert und kann durch ein Ausrichtmittel 2 gegebenenfalls mit einem Ausrichtlineal 21 achsfluchtend gerichtet werden. Ein Quertransportmittel 5 mit Tragarmen 51 und jeweils einer Walzgutauflage 52 ist in den Bereich des Rollganges 1 rückführbar angeordnet. Es ist jedoch auch möglich, ein derartiges Quertransportmittel 5 im Bereich des .Kühlbettes festzulegen.As further shown in FIG. 1, a rail S coming from a roller mill (not shown) is positioned on the roller table 1 and can be aligned by means of an alignment means 2 with an alignment ruler 21 if necessary. A transverse transport means 5 with support arms 51 and in each case one rolling stock support 52 is arranged to be traceable into the area of the roller table 1. However, it is also possible to fix such a transverse transport means 5 in the area of the cooling bed.
Zum Quertransport erfolgt eine simultane Verschiebung der Tragarme 51 derart, daß die darauf angeordneten Walzgutauflagen 52 bei deren Anheben die Schiene S vom Rollgang 1 achsfluchtend abheben, tragen und quer in die Richtung des Kühlbettes 4 verbringen können. Dabei ist es erfindungswesentlich, daß im Zuge eines Quertransportes ausschließlich die Walzgutauflagen 52 des Quertransportmittels 5, auch wenn die Auflagen 52 in den äußersten gegenüberliegenden Bereich verfahren sind, zum Beispiel bei einem Ablegen einer Schiene S, auf einen Ablagebereich 41 des Kühlbettes 4, eine Förderebene 11 des Rollganges vertikal überragen können.For transverse transport, there is a simultaneous displacement of the support arms 51 in such a way that the rolling material supports 52 arranged thereon, when they are lifted, lift the rail S off the roller table 1 in alignment with the axis, carry it and spend it transversely in the direction of the cooling bed 4. It is essential to the invention that in the course of a transverse transport only the rolling stock supports 52 of the transverse transport means 5, even if the supports 52 are moved to the outermost opposite area, for example when a rail S is placed on a storage area 41 of the cooling bed 4, a conveying plane 11 of the roller table can project vertically.
Eine positionierte und axial ausgerichtete Schiene S, die vorteilhaft in zwei Querschnittsbereichen auf der Förderebene 11 des Rollganges 1 liegt, kann nun in dieser Lage mittels der Walzgutauflage 52 vertikal abgehoben und im wesentlichen horizontal bzw. quer zu einer in Bereitschaft stehenden Flüssigkeitskühleinrichtung, in Fig. 1 Position 32, verbracht werden. Eine derartige Querschnittslage der Schiene S auf den Walzgutauflagen 52 ist günstig für eine Übernahme derselben und eine " Kopf unten" Vertikalstellung durch einen Manipulator 321 , mittels welchen auch ein Absenken oder Einbringen des Schienenkopfes in eine Kühlflüssigkeit 325 erfolgen kann. Während der Verweilzeit der Schiene in der Kühlflüssigkeit 325 kann diese zwecks einer Stabilisierung mittels Niederhaltemittel 324 und Nivellierungsanschläge 323 eingespannt sein.A positioned and axially aligned rail S, which advantageously lies in two cross-sectional areas on the conveying plane 11 of the roller table 1, can now be lifted vertically and essentially in this position by means of the rolling stock support 52 horizontally or transversely to a liquid cooling device which is on standby, in FIG. 1, position 32. Such a cross-sectional position of the rail S on the rolling stock supports 52 is favorable for the transfer thereof and a "head down" vertical position by a manipulator 321, by means of which the rail head can also be lowered or introduced into a coolant 325. During the dwell time of the rail in the cooling liquid 325, the latter can be clamped in for the purpose of stabilization by means of hold-down means 324 and leveling stops 323.
Weil erfindungsgemäß, wie vorher erwähnt, ausschließlich die Walzgutauflagen 52 auf ein über der Förderebene 11 des Rollganlges 1 gelegenes Niveau gebracht werden können, kann trotz Quertransportaktivitäten eine Folgeschiene vom Walzwerk auf den Rollgang 1 gebracht werden und auf diesem ein- und ausgerichtet werden. Ein Ausbringen einer Schiene S aus den Flüssigkeitseinrichtungen 31,32 mittels Manipulatoren 311 , 321 und ein Abnehmen derselben durch die Walzgutauflagen 52 kann im wesentlichen gleichartig erfolgen, wonach ein Verbringen und Auflegen auf den Ablagebereich 41 des Kühlbettes 4 erfolgen.Because, according to the invention, as previously mentioned, only the rolling stock supports 52 can be brought to a level above the conveying plane 11 of the rolling unit 1, despite transverse transport activities, a follower rail can be brought from the rolling mill to the roller table 1 and set up and aligned thereon. A rail S can be brought out of the liquid devices 31, 32 by means of manipulators 311, 321 and removed by the rolling material supports 52, essentially in the same way, after which they are brought and placed on the storage area 41 of the cooling bed 4.
Bei hohen Walzleistungen kann die Härteeinrichtung 3 auch mit mehr als zwei Flussigkuhleinrichtungen ausgeführt sei, allenfalls ist eine programmierbare Steuereinheit vorteilhaft für einen Fertigungsablauf einsetzbar. At high rolling capacities, the hardening device 3 can also be designed with more than two liquid cooling devices; at most, a programmable control unit can advantageously be used for a production process.
