Bei einem Konverter handelt es sich um ein kippbares metallurgisches Behandlungsgefäß, in dem flüssige Metalle und Metalllegierungen hergestellt und behandelt werden. Ein Konverter ist während des Betriebes hohen thermischen Belastungen ausgesetzt, die zu Wärmedehnungen führen können. Entsprechend ist ein Konverter mit einem vorbestimmten Abstand an einem umgebenden Tragring angebracht.A converter is a tiltable metallurgical treatment vessel in which liquid metals and metal alloys are manufactured and treated. A converter is exposed during operation to high thermal loads, which can lead to thermal expansion. Accordingly, a converter is mounted at a predetermined distance on a surrounding support ring.
Im Stand der Technik ist aus
Der Erfindung liegt die Aufgabe zugrunde, ein Befestigungssystem für kippbare metallurgische Behandlungsgefäße und ein dafür geeignetes Behandlungsgefäß zu schaffen, wobei das Befestigungssystem mit einfachen und robusten Mitteln gegen mögliche Verschmutzungen geschützt ist und deshalb Wärmedehnungen des Behandlungsgefäβes zuverlässig gewährleistet sind.The invention has for its object to provide a mounting system for tiltable metallurgical treatment vessels and a suitable treatment vessel, the fastening system is protected by simple and robust means against possible contamination and therefore thermal expansion of the Behandlungsgefäβes are reliably guaranteed.
Diese Aufgabe wird durch ein Befestigungssystem mit den Merkmalen von Anspruch 1, und durch ein Behandlungsgefäß gemäß Anspruch 15 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen definiert.This object is achieved by a fastening system with the features of claim 1, and by a treatment vessel according to
Das Befestigungssystem gemäß der vorliegenden Erfindung eignet sich für kippbare metallurgische Behandlungsgefäße, insbesondere Konverter, und umfasst einen Tragring, der zwei diametral entgegengesetzte Kippzapfen aufweist, wobei ein Behandlungsgefäß mit einer Vielzahl von Verbindungselementen an dem Tragring angebracht werden kann. Das Befestigungssystem umfasst weiter Haltemittel, die an einer Außenseite des Behandlungsgefäßes anbringbar sind, und Führungsmittel, die an dem Tragring ausgebildet sind und mit den Haltemitteln zusammenwirken, um Kippkräfte von dem Behandlungsgefäß an den Tragring abzuleiten. Sowohl die Haltemittel als auch die Führungsmittel sind jeweils an einer Unterseite des Tragrings angeordnet. Die Haltemittel umfassen einen vertikal nach oben gerichteten Lastbolzen. Die Führungsmittel sind als ein an der Unterseite des Tragrings vorgesehenes Langloch ausgebildet, wobei der Lastbolzen in das Langloch eingreift. In einer Grundstellung des Tragrings verläuft die Längsachse des Tragrings in einer zur Mittelachse des Behandlungsgefäßes senkrechten Ebene und parallel zur Kippachse des Behandlungsgefäßes, wobei in der vertikalen Betriebsstellung des Behandlungsgefäßes der Lastbolzen derart in dem Langloch positioniert ist, dass der Lastbolzen innerhalb des Langlochs entlang einer Achse bzw. der Längsachse des Langlochs, die radial in Richtung eines Mittelpunkts des Behandlungsgefäßes weist, und/oder in vertikaler Richtung verschieblich ist.The fastening system according to the present invention is suitable for tiltable metallurgical treatment vessels, in particular converters, and comprises a support ring having two diametrically opposed tilting pins, wherein a treatment vessel with a plurality of connecting elements can be attached to the support ring. The fastening system further comprises retaining means, which are attachable to an outer side of the treatment vessel, and guide means, which are formed on the support ring and cooperate with the holding means to divert tilting forces from the treatment vessel to the support ring. Both the holding means and the guide means are each arranged on an underside of the support ring. The retaining means comprise a vertically upwardly directed load bolt. The guide means are formed as a provided on the underside of the support ring slot, wherein the load pin engages in the slot. In a basic position of the support ring, the longitudinal axis of the support ring extends in a plane perpendicular to the central axis of the treatment vessel and parallel to the tilt axis of the treatment vessel, wherein in the vertical operating position of the treatment vessel, the load pin is positioned in the slot, that the load bolt within the slot along an axis respectively. the longitudinal axis of the slot, which points radially towards a center of the treatment vessel, and / or is displaceable in the vertical direction.
Der Erfindung liegt die wesentliche Erkenntnis zugrunde, dass durch ein Zusammenwirken der Haltemittel und der Führungsmittel bei einem Verschwenken des Tragrings Kippkräfte sicher und spielfrei von dem Behandlungsgefäß an den Tragring abgeleitet werden können. Durch die Anordnung der Halte- und Führungsmittel an einer Unterseite des Tragrings sind diese Mittel "automatisch", da konstruktionsbedingt, gegen eine Verschmutzung z. B. durch Schlackeauswürfe geschützt, die von oben aus einer Öffnung des Behandlungsgefäßes auf eine Oberseite des Tragrings gelangen können. Das Zusammenwirken der Haltemittel mit den Führungsmitteln ist derart ausgestaltet, dass in Folge einer Wärmedehnung des Behandlungsgefäßes eine Bewegung des Haltemittels relativ zu den Führungsmitteln sowohl in vertikaler Richtung nach oben bzw. unten als auch entlang einer Achse, die radial in Richtung eines Mittelpunktes des Behandlungsgefäßes weist, wartungsfrei möglich ist. Da die Haltemittel und die Führungsmittel wie erläutert gegen eine Verschmutzung hinreichend geschützt sind, ist diese Beweglichkeit auch im Betrieb des Behandlungsgefäßes, bei dem erhebliche Temperaturschwankungen auftreten können, zuverlässig gewährleistet.The invention is based on the essential finding that tilting forces can be reliably and without clearance derived from the treatment vessel to the support ring by an interaction of the holding means and the guide means during pivoting of the support ring. Due to the arrangement of the holding and guiding means on an underside of the support ring, these means are "automatic" because of design, against contamination z. B. protected by Schlackeauswürfe that can get from the top of an opening of the treatment vessel on top of the support ring. The interaction of the holding means with the guide means is configured such that, as a result of thermal expansion of the treatment vessel, a movement of the holding means relative to the guide means in both the vertical upward and downward and along an axis which points radially towards a center of the treatment vessel , maintenance-free is possible. Since the holding means and the guide means are sufficiently protected as described against contamination, this mobility is reliably ensured even in the operation of the treatment vessel, in which considerable temperature fluctuations can occur.
Zweckmäßigerweise umfassen die Haltemittel einen vertikal nach oben gerichteten Lastbolzen, der in die Führungsmittel in Form eines an der Unterseite des Tragrings ausgebildeten Langloches eingreift. Die Ausgestaltung der Halte- und Führungsmittel ist wartungsfrei und stellt in robuster Weise die soeben erläuterte Beweglichkeit der Haltemittel in vertikaler und radialer Richtung sicher. Des Weiteren sind hiermit die Vorteile einer einfachen Zugänglichkeit und Montagemöglichkeit gegeben.Conveniently, the holding means comprise a vertically upwardly directed load bolt which engages in the guide means in the form of an elongated hole formed on the underside of the support ring. The design of the holding and guiding means is maintenance-free and ensures in a robust manner just described mobility of the holding means in the vertical and radial directions. Furthermore, this gives the advantages of easy accessibility and installation options.
In einer Grundstellung des Tragrings, wenn das Behandlungsgefäß mit seiner Hochachse vertikal angeordnet ist, verläuft die Längsachse des Langloches horizontal und parallel zu einer Kippachse des Behandlungsgefäßes. In diesem Zusammenhang wird darauf hingewiesen, dass der Lastbolzen in einer vertikalen Betriebsstellung des Behandlungsgefäßes im Wesentlichen mittig innerhalb des Langloches in Bezug auf dessen Längsachse positioniert ist. Die genannte Betriebsstellung des Behandlungsgefäßes ist dahingehend zu verstehen, dass das Behandlungsgefäß einsatzbereit an dem Tragring montiert bzw. abgestützt ist, wobei die energetische Inbetriebnahme noch nicht stattgefunden hat und somit das Behandlungsgefäß im Wesentlichen Umgebungstemperatur aufweist.In a basic position of the support ring, when the treatment vessel is arranged vertically with its vertical axis, the longitudinal axis of the elongated hole extends horizontally and parallel to a tilting axis of the treatment vessel. In this context, it should be noted that the load pin is positioned in a vertical operating position of the treatment vessel substantially centrally within the elongated hole with respect to its longitudinal axis. The said operating position of the treatment vessel is to be understood as meaning that the treatment vessel is ready mounted or supported on the support ring, wherein the energetic startup is not yet has taken place and thus the treatment vessel has substantially ambient temperature.
Ein weiterer Vorteil für das erfindungsgemäße Befestigungssystem wird dadurch erzielt, dass es außerhalb der direkten Wärmestrahlung durch die Pfanne während des Abstichs angeordnet ist und insoweit einer geringeren Temperaturwechselbelastung unterliegt.Another advantage for the fastening system according to the invention is achieved in that it is arranged outside of the direct heat radiation through the pan during the tapping and thus subject to a lower thermal cycling.
Erfindungsgemäß ist weiter ein Behandlungsgefäß, insbesondere in Form eines Konverters, vorgesehen, wobei an einer Aussenseite des Behandlungsgefäßes Haltemittel angebracht sind, die mit Führungsmitteln des vorstehend erläuterten Befestigungssystems zusammenwirken.According to the invention, a treatment vessel, in particular in the form of a converter, is furthermore provided, holding means being mounted on an outer side of the treatment vessel and cooperating with guide means of the above-described fastening system.

Die Verbindungselemente 7 sind in Form von Lamellen ausgebildet, wobei der Konverter 2 mit den Lamellen 7 an dem Tragring 3 aufgehängt bzw. abgestützt ist. Durch die Aufhängung mittels der Lamellen 7 kann eine radiale Wärmedehnung des Konverters 2 kompensiert werden. Die Abstützung des Konverters 2 mittels solcher Lamellen 7 an dem Tragring 3 ist im Stand der Technik z. B. aus
Das Befestigungssystem 1 nach der vorliegenden Erfindung umfasst Haltemittel 8, die an einer Außenseite des Konverters 2 angebracht sind.

Die Haltemittel 8 umfassen einen Lastbolzen 10, der an einer an der Wandung des Konverters 2 befestigten Außenkonsole 11 angebracht ist. Der Lastbolzen 10 erstreckt sich mit seiner Längsachse ausgehend von einer Grundfläche 12 der Außenkonsole 11 vertikal nach oben. Der Lastbolzen 10 kann an der Außenkonsole 11 durch eine Verschraubung 13 befestigt sein, die in
Das Langloch 9 ist in einem Untergurt 14 des kastenförmigen Tragrings 3 ausgebildet. Der Lastbolzen 10 greift derart in das Langloch 9 ein, dass er entlang der Längsachse des Langloches 9 bzw. entlang einer Achse (y), die radial in Richtung eines Mittelpunktes des Konverters 2 weist, beweglich ist. Des Weiteren ist die Grundfläche 12 der Außenkonsole 11 ausreichend weit von dem Untergurt 13 des Tragrings 3 beabstandet, so dass der Lastbolzen 10 innerhalb des Langlochs 9 auch in vertikaler Richtung (z) beweglich ist.The
Die Anordnung des Lastbolzens 10 innerhalb des Langlochs 9 ist ergänzend in der
Die Erfindung funktioniert nun wie folgt:
Falls der Konverter 2 im Betrieb durch eine Rotation desTragrings 3 zur Seite verschwenkt wird, entstehen Kippkräfte, dieauf den Konverter 2 einwirken. Diese Kippkräfte treten unter Bezugnahme auf dieFig. 1 in Richtung der x-Achse auf. Wie oben zuFig. 3 erläutert,ist der Lastbolzen 10 seitlich anden Längsseitenrändern 15 desLanglochs 9 spielfrei geführt bzw. fixiert. Entsprechend können die auftretenden Kippkräfte desKonverters 2 schlüssig inden Tragring 3 abgeleitet werden. Von Vorteil hierbei ist, dass der Lastbolzen 10 in Verbindungmit dem Langloch 9 jeweils an diametral entgegengesetzten Seiten desKonverters 2 vorgesehen ist, nämlich direkt unterhalb der Bereiche, wo diebeiden Kippzapfen 4 jeweils inden Tragring 3 eingreifen.- Falls es im Betrieb des Konverters 2 in Folge von wechselnden Temperaturen zu Wärmedehnungen kommt, so können diese Dehnungen durch das Gleiten des Lastbolzens 10 ausgeglichen werden, nämlich entweder in Richtung einer Längsachse (y) des Langlochs 9 und/oder in vertikaler Richtung (z) nach oben oder nach unten. Die
Materialpaarungen von Lastbolzen 10 und der Längsseitenränder 15 desLanglochs 9 sind geeignet wartungsfrei ausgeführt und gewährleisten ein klemmfreies Gleiten des Lastbolzens 10 innerhalb desLanglochs 9.
- If the
converter 2 is pivoted in operation by a rotation of thesupport ring 3 to the side, tilting forces, which act on theconverter 2. These tipping forces occur with reference to FIGSFig. 1 in the direction of the x-axis. As aboveFig. 3 explained, theload pin 10 is laterally guided or fixed free of play on the longitudinal side edges 15 of theslot 9. Accordingly, the occurring tilting forces of theconverter 2 can be derived in a conclusive manner in thesupport ring 3. The advantage here is that theload pin 10 in conjunction with theslot 9 each is provided diametrically opposite sides of theconverter 2, namely directly below the areas where the twopivot pins 4 each engage in thesupport ring 3. - If, during operation of the
converter 2, thermal expansion occurs as a result of changing temperatures, these strains can be compensated by the sliding of theload bolt 10, namely either in the direction of a longitudinal axis (y) of theslot 9 and / or in the vertical direction (z). up or down. The material pairings ofload bolts 10 and the longitudinal side edges 15 of theslot 9 are designed to be suitable maintenance-free and ensure a jam-free sliding of theload bolt 10 within theslot 9.
In den
An den Längsseitenrändern 15 des Langlochs 9 sind im Kontaktbereich zum Lastbolzen 10 Gleitplatten 18 befestigt. Das Zusammenwirken der Gleitplatten 18 und der Druckplatten 17 ist in
Die Druckplatten 17 bzw. die Gleitplatten 18 sind vorzugsweise aus einem Material hergestellt, das verschleißfest ist und gleichzeitig gute Gleiteigenschaften aufweist, z.B. gehärteter Stahl oder entsprechende Stahllegierungen. Optional können die Druckplatten 17 bzw. die Gleitplatten 18 mit widerstandsfähigen Beschichtungen versehen sein, die weiter verbesserte Gleiteigenschaften haben.The
Für eine möglichst einfache Montage des Konverters 2 an dem Tragring 3 bzw. eine entsprechende Justierung des Lastbolzens 10 innerhalb des Langlochs 9 vor einer Inbetriebnahme des Konverters 2 sind bewegliche Keilelemente 19 vorgesehen, die jeweils an den Längsseitenrändern 15 des Langlochs 9 angebracht sind. Ein jeweiliges Keilelement 19 weist eine vertikale Seitenfläche 20 und entgegengesetzt dazu eine schräge Keilfläche 21 auf. Die schräge Keilfläche 21 liegt an einer komplementär dazu geneigten Kontaktfläche 22 des Tragrings 3 an.
Ein jeweiliges Keilelement 19 umfasst einen oberen Schulterabschnitt 23, der eine im Wesentlichen horizontal verlaufende untere Bodenfläche 24 aufweist. Angrenzend an den Schulterabschnitt 23 ist an dem Tragring 3 ein Sockelabschnitt 25 mit einer horizontalen Auflagefläche vorgesehen.A
Die vorstehend erläuterten Gleitplatten 18 lassen sich an der vertikalen Seitenfläche 20 eines Keilelementes 19 befestigen, z. B. unter Verwendung einer Verschraubung 26. Optional können in den vertikalen Seitenflächen 20 Vertiefungen 27 ausgebildet sein, in denen die Gleitplatten 18 aufgenommen sind. Durch die Seitenwände der Vertiefung 27 werden vorteilhaft die Querkräfte aufgenommen, die bei einer Gleitbewegung des Lastbolzens 10 innerhalb des Langlochs 9 auf die Gleitplatten 18 einwirken.The sliding
