Description

Die Erfindung bezieht sich auf eine Einrichtung zum Härten von Schienen, insbesondere profilierten Fahrschienen, mit gegebenenfalls jeweils unterschiedlicher Querschnittsform und einer Länge von größer als 50m durch Abkühlen von zumindest einem Teil des jeweiligen Schienenquerschnittes über die gesamte Schienenlänge in einem Kühlmittel, bestehend aus Querverschiebemitteln im Bereich eines Rollganges, aus Richtmitteln und Manipulationsgreifer zum Verbringen der Schiene in der Einrichtung, mindestens einem Positioniermittel, mit jeweils einem Becken bzw. Trog mit Kühlmittel sowie einem Kühlbett.The invention relates to a device for hardening rails, in particular profiled rails, optionally with respectively different cross-sectional shape and a length of greater than 50m by cooling at least part of the respective rail cross-section over the entire rail length in a coolant, consisting of Querverschiebemitteln in the area a roller table, of directing means and manipulation gripper for moving the rail in the device, at least one positioning means, each with a basin or trough with coolant and a cooling bed.

Schienen aus Kohlenstoff enthaltenden, gegebenenfalls niedriglegierten Stählen, die nach dem Walzen auf ein Kühlbett verbracht und erkalten gelassen werden, weisen durchwegs ein perlitisches Gefüge auf, wobei der Werkstoff dementsprechende mechanische Eigenschaften hat. Um den Schienenverschleiß, insbesondere bei hohen Achslasten sowie gegebenenfalls hoher Geschwindigkeit der Züge und in engen Kurven zu verringern, kann gemäß Stand der Technik durch eine besondere Wärmebehandlung die Gefügestruktur derart eingestellt werden, dass zumindest der beanspruchte Schienenkopf eine hohe Härte, eine hohe Abriebfestigkeit und eine geringe Rissinitiation hat, d.h., dass die Schiene im Gleis verbesserte Gebrauchseigenschaften aufweist.Rails of carbon-containing, optionally low-alloy steels, which are placed on a cooling bed after rolling and allowed to cool, have a pearlitic structure throughout, the material having corresponding mechanical properties. In order to reduce the rail wear, especially at high axle loads and possibly high speed trains and tight curves, the microstructure can be adjusted in such a way that at least the claimed rail head high hardness, high abrasion resistance and a has low Rissinitiation, ie, that the rail in the track has improved performance characteristics.

Eine Einrichtung zum Härten von Schienen durch eine gezielte Ausbildung der Gefügestruktur bei der Abkühlung derselben kann für einen Durchlauf durch eine Sprühkühlvorrichtung oder für ein Tauchen in ein Kühlmittel ausgebildet sein.A device for hardening rails by a targeted formation of the microstructure during the cooling of the same can be designed for a passage through a spray cooling device or for a dip in a coolant.

Durchlauf-Sprühkühlanlagen für eine Schienenhärtung sind in der Regel zwar einfach aufgebaut, haben jedoch den Nachteil eines großen Platzbedarfes, benötigen eine aufwändige Technologie und können auch unerwünschte Güteschwankungen der Schienen in einem Produktionsablauf nicht effizient ausschließen. Weiters kann oft in einer Durchlauf-Sprüheinrichtung eine genaue Abstimmung der Kühlung auf wechselnde Querschnittsprofile wie Zungen-, Rillen-, Vignolschienen und dgl. nicht in erforderlichem Maße erfolgen, wobei auch gegebenenfalls ein Verzug bei der Abkühlung von Querschnittsbereichen im Durchlauf zu ungleichen Kühlmittelbeaufschlagungen und somit zu Härteschwankungen des Werkstoffes über die Schienenlänge führt.Continuous spray cooling systems for rail hardening are generally simple in construction, but have the disadvantage of a large footprint, require a complex technology and can not exclude unwanted Güteschwankungen the rails in a production process not efficient. Furthermore, a precise tuning of the cooling to changing cross-sectional profiles such as tongue, groove, Vignol rails and the like. Not often done in a continuous sprayer to the extent necessary, with also possibly a delay in the cooling of cross-sectional areas in the flow to uneven Kühlmittelbeaufschlagungen and thus leads to hardness variations of the material over the rail length.

Es wurde schon vorgeschlagen, bei einer Sprühvergütung der Schiene diese unbewegt zu belassen oder nur geringfügig, bevorzugt um den jeweiligen Sprühmittelabstand, alternierend zu verschieben.It has already been proposed, in the case of spray coating of the rail, to leave it stationary or to shift it only slightly, preferably by the respective spray agent spacing, alternately.

Weiters ist bekannt, eine Vorrichtung zum thermischen Vergüten von Schienen und/oder von Teilen des Querschnitts von Schienen mit einem oder mehreren Tauchbecken für diese auszubilden.Furthermore, it is known to form a device for thermal annealing of rails and / or parts of the cross section of rails with one or more immersion tanks for this.

Bei sequentieller Herstellung von gehärteten Schienen mit hoher Walzleistung wurde gemäß AT 410 549 B schon vorgeschlagen, mindestens zwei Flüssigkeitskühleinrichtungen jeweils parallel zu einem Ausrichtmittel anzuordnen und Quertransportmittel mit Walzgutauflagen zwischen den Rollgangsrollen vorzusehen, um ein Verbringen einer Schiene vom Rollgang zu Manipulatoren der Kühleinrichtung und in der Folge von diesen in den Auflagebereich eines Kühlbettes zu bewerkstelligen. Derart kann eine Steigerung der Durchsatzmenge von Schienen durch die Vergüteanlage erreicht werden. Ein Auslaufen aus dem Walzgerüst, ein Ausrichten und ein Drehen der Schiene am Rollgang ist jedoch bei aktivem Ausrichtmittel nicht uneingeschränkt möglich.In sequential production of hardened rails with high rolling performance was according to AT 410 549 B already proposed to arrange at least two liquid cooling devices in each case parallel to an alignment and provide transverse transport means with Walzgutauflagen between the roller conveyor rollers to accomplish a movement of a rail from the roller table to manipulators of the cooling device and in consequence of this in the support area of a cooling bed. In this way, an increase in the throughput of rails through the annealing plant can be achieved. However, leakage from the rolling stand, alignment and rotation of the rail on the roller table is not fully possible with active alignment.

Hier will die Erfindung die Mängel beseitigen und setzt sich zum Ziel, eine Einrichtung der eingangs genannten Art zum Härten von Schienen, insbesondere von profilierten Fahrschienen, zu schaffen, mit welcher bei hohem Durchsatz mit großer Sicherheit qualitativ hochwertige Schienen wirtschaftlich herstellbar sind.Here, the invention seeks to remedy the deficiencies and sets itself the goal of creating a device of the type mentioned for the hardening of rails, especially profiled rails, with which high throughput with high reliability high quality rails can be produced economically.

Im Einzelnen soll eine Anlage entsprechend der Zielsetzung einen Manipulationsgreifer für ein ungehindert rasches Verbringen der aus den Walzen auslaufenden Schienen aufweisen, welcher eine axiale Ausrichtung derselben ermöglicht, sowie eine maßgenaue Einbringbarkeit in einem Positioniermittel und/oder ein Ablegen auf ein Übergabemittel und/oder auf ein Kühlbett bewerkstelligt aufweisen.In detail, a system according to the objective of a manipulation gripper for an unimpeded rapid movement of the expiring from the rollers rails, which allows axial alignment thereof, and a dimensionally accurate Einbringbarkeit in a positioning and / or depositing on a transfer agent and / or on a Cooling bed accomplished exhibit.

Das Ziel wird bei einer gattungsgemäßen Einrichtung erreicht, wenn der Manipulationsgreifer aus Zangen gebildet ist, die Greifarme aufweisen, die jeweils mit Zentrierteilen für ein axiales Ausrichten des Kopfes der Schiene und mit Greifteilen für ein querschnittsfluchtendes Halten des Schienenfußes ausgeformt sind und derart eine maßgenaue Einbringung der Schiene im Positioniermittel und eine Festlegung derselben in diesem ermöglicht ist.The goal is achieved in a generic device, when the manipulation gripper is formed from pliers having gripping arms, which are each formed with centering parts for an axial alignment of the head of the rail and with gripping parts for cross-aligned holding the rail foot and thus a dimensionally accurate introduction of Rail in the positioning and a determination of the same is possible in this.

Die Vorteile, die mit einem erfindungsgemäßen Manipulationsgreifer erreicht werden, sind im Wesentlichen darin zu sehen, dass dessen fluchtende Zangen Greifarme mit Zentrierteilen und Greifteilen aufweisen, sodass die Schiene unmittelbar nach dem letzten Walzstich und deren Auslaufen am Rollgang in der Walzhitze, also im duktilen bzw. weitgehend plastischen Zustand des Werkstoffes beim Schließen der Zangenteile vorerst kopfseitig axial ausrichtbar ist, worauf ein querschnittsfluchtendes Halten des Schienenfußes erfolgt und dabei Schienen nach axialem Drehen immer gleicher Art in ein Positioniermittel eingebracht oder auf ein Kühlbett aufgelegt werden können. Diese Art der Schieneneinbringung in ein Positioniermittel mit horizontal ausgerichtetem, fluchtendem Schienenfuß hängend hat den weiteren Vorteil, dass in diesem die Lage des Schienenfußes immer gleichartig vorliegt und diese gleichbleibende Lage auch bei unsymmetrischen Querschnittsprofilen gesichert werden kann.The advantages that are achieved with a manipulation gripper according to the invention are essentially to be seen in that its aligned pliers have gripping arms with centering parts and gripping parts, so that the rail immediately after the last rolling pass and their expiry on the roller table in the rolling heat, ie in the ductile or ., largely plastic state of the material when closing the pliers parts at first head side axially aligned, where a cross-aligned alignment of the rail takes place while rails after axial rotation always introduced the same kind in a positioning or can be placed on a cooling bed. This type of rail insertion into a positioning with horizontally aligned, aligned rail foot hanging has the further advantage that in this the position of the rail foot is always the same and this constant position can be secured even with asymmetrical cross-sectional profiles.

Die Zangen sind dabei um eine gemeinsame Axe zumindest mit einem Winkelbetrag gleichzeitig gleichsinnig drehbar ausgeführt, um Schienen aus unterschiedlichen Rollgang-Positionen, z.B. aus einer Liegeposition kopfseitig ausrichten, querschnittsfluchtend halten und durch axiales Drehen maßgenau in ein Positioniermittel einbringen zu können.The pliers are at the same time rotatable in the same direction about a common axis at least with an angular amount to align rails from different roller positions, eg from a reclining position on the head side, hold cross-section aligned and accurately by axial rotation to be able to bring into a positioning.

Im Zuge des Austrages der Schiene aus dem Positioniermittel kann durch eine Drehung der Zangen die Schiene mit Vorteil in einer gewünschten Querschnitts- Lage auf ein Übergabemittel und/oder auf einem Kühlbett abgelegt werden.In the course of the discharge of the rail from the positioning means can be stored by rotation of the pliers, the rail with advantage in a desired cross-sectional position on a transfer agent and / or on a cooling bed.

Mit vorteilhaft hoher Präzision kann ein Verbringen von ausgerichteten Schienen in kurzer Zeit erfolgen, wenn der Manipulationsgreifer mit mehr als zwei Zangen je 10m Beckenlänge gebildet ist.With advantageously high precision, it is possible to dispose of aligned rails in a short time if the manipulation gripper is formed with more than two pliers per 10 m basin length.

Sowohl funktionstechnisch als auch im Hinblick auf das Ausricht- und Greifverhalten ist es günstig, wenn die Zangen mit jeweils einem gleichartig bewegbaren bzw. anstellbaren Greifarm gebildet sind.Both functionally and in terms of the alignment and gripping behavior, it is advantageous if the pliers are each formed with a similarly movable or engageable gripping arm.

Wenn in vorteilhafter Weise der Manipulationsgreifer und die zugehörigen Verbringungsmittel beabstandet mit mehr als der größten Schienenhöhe über dem Rollgang querbewegbar und nur die Greifarme der Zangen teilweise zwischen die Rollen des Rollganges zum Aufnehmen der Schiene vertikal absenkbar sind, bleibt eine Beaufschlagung des Rollgangendbereiches mit aus den Walzen auslaufenden Schienen ungestört bezüglich eines gleichzeitigen Verbringens von Schienen in der Härteeinrichtung, was eine hohe Flexibilität und Leistung derselben bzw. einen hohen Durchsatz sicherstellt.If, advantageously, the manipulation gripper and the associated transfer means can be moved transversely with more than the greatest rail height over the roller table and only the gripping arms of the pliers can be lowered vertically between the rollers of the roller table for receiving the rail, loading of the roller table end area from the rollers remains leaking rails undisturbed with respect to a simultaneous placement of rails in the hardening device, which ensures high flexibility and performance of the same or a high throughput.
