Description
Die Erfindung betrifft ein Gefäß für die metallurgische Behandlung von Roheisen, Stählschmelzen u. dgl., insbesondere ein Konvertergefäß, das sich auf einen mit Abstand angeordneten Tragring abstützt, der mittels Kippzapfen in beidseitigen Kipplagem kippbar ist, wobei über den Umfang der Gefäßwandung verteilte Pratzen auf dem Obergurt des Tragrings aufliegen und wobei die Abstützung auf dem Obergurt des Tragrings mittels zusätzlichen Befestigungsmitteln lösbar ausgebildet ist.The invention relates to a vessel for the metallurgical treatment of pig iron, steel melts u. Like., In particular, a converter vessel, which is supported on a spaced-apart support ring which is tiltable by means of tilting pin in both sides Kipplagem, over the circumference of the vessel wall distributed claws rest on the upper flange of the support ring and wherein the support on the upper flange of the support ring means additional fastening means is detachably formed.
Die Aufgabe, ein Konvertergefäß etwa der vorstehenden Gestaltung zu schaffen, dessen Einzelteile mit einfachen Mitteln auswechselbar sind und dazu die Verbindung zwischen den Gefäß-Pratzen und dem Tragring sowie zwischen Führungsstücken und zusätzlichen Befestigungselementen lösbar zu machen, ist bekannt (DE 199 28 195 A1). Dazu fehlt es jedoch an geeigneten Mitteln, unter den Bedingungen eines heißen Konvertergefäßes dieses Lösen und Wiederbefestigen eines zu wechselnden Gefäßes durchzuführen.The object to provide a converter vessel about the above design, the items are interchangeable with simple means and to make the connection between the vessel claws and the support ring and between guide pieces and additional fasteners solvable is known (DE 199 28 195 A1) , For this purpose, however, there is a lack of suitable means to perform under the conditions of a hot converter vessel this loosening and Wiederbefestigen a vessel to be changed.
in der Praxis erfordern metallurgische Behandlungsgefäße aufgrund des relativ hohen Ausmauerungs-Verschleißes einen schnellen Austausch, um die Produktiensausfallzeit gering zu halten.in practice, metallurgical treatment vessels require rapid replacement due to the relatively high lining wear in order to minimize product downtime.
Die Grundlage bilden bisher zu den in oben offenen Führungen liegenden Pratzen hinzukommende Befestigungselemente, wie bspw. Klemmschrauben, klappbare Schrauben sowie Zangenmechanismen mit entsprechender Betätigung, die alle die angegebenen Nachteile aufweisen und nur sehr schwierig handhabbar sind und deren Handhabung zuviel Zeit in Anspruch nimmt. Aufgrund der betriebsbedingten Erwärmung der Gefäße treten außerdem Wärmedehnungen in den einzelnen Bauteilen auf, die das Lösen der Befestigungselemente erschweren. Darüber hinaus kommt noch hinzu, dass der Löse- und Wechselvorgang bei den erhöhten Umgebungstemperaturen durch das Bedienungspersonal aus nächster Nähe durchgeführt werden muss. Bei der relativ beengten Zugänglichkeit ist ein Lösen von Spannmuttern mit entsprechendem Werkzeug ziemlich kraftaufwändig.The basis form so far to the lying in the top open guides claws fasteners, such as. Clamping screws, hinged screws and pincer mechanisms with appropriate operation, all of which have the stated disadvantages and are very difficult to handle and their handling takes too much time. Due to the operational heating of the vessels also occur thermal expansions in the individual components that complicate the release of the fasteners. In addition, there is also the fact that the release and change process must be carried out at the increased ambient temperatures by the operator from close range. In the relatively tight accessibility loosening of clamping nuts with appropriate tool is quite power consuming.
Der Erfindung liegt die Aufgabe zugrunde, ein schnell, leicht und im ausreichenden Abstand handhabbares Mittel vorzuschlagen, das die genannten Nachteile nicht aufweist.The invention has for its object to provide a fast, easy and manageable at a sufficient distance means that does not have the disadvantages mentioned.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Abstützung auf dem Obergurt des Tragrings aus jeweils sich gegenüberliegenden Gefäß-Konsolen und Tragring-Konsolen besteht, die mittels eines Klappverschlusses in einer Schließrichtung bis in eine gesicherte Schließstellung miteinander verspannbar und in einer entgegengesetzten Betätigungsrichtung leicht lösbar sind. Im Schließzustand wird ein Betätigungselement über den sog. Totpunkt hinweg bewegt und kann in eine selbsthemmende und verriegelungssichere Lage gebracht werden. Die am Umfang verteilten Konsolen können je nach Tragringform symmetrisch oder asymmetrisch angeordnet sein und dienen als Angriffsstellen für eine solche Schnell-Befestigungseinrichtung. Das sich ergebende Hebelsystem ist auf die Klemmabstände abgestimmt und gewährleistet den sicheren Halt des Gefäßes auch in Kipppositionen. Der Klappverschluss kann weiterhin mit einem manuell anzubringenden hydraulischen Handhabungsgerät leicht und sicher in die Schließstellung oder die LöseStellung gedrückt werden. Zum Öffnen kann demzufolge dasselbe Hilfsgerät angesetzt werden. Dabei wird zuerst aus der Totpunktlage herausgefahren, bis die Offenstellung erreicht ist.The stated object is achieved in that the support on the upper flange of the support ring consists of each opposite vessel brackets and support ring brackets, which by means of a snap closure in a closed direction to a secure closed position with each other braced and easily detachable in an opposite direction of actuation are. In the closed state, an actuating element is moved beyond the so-called dead center and can be brought into a self-locking and lock-secure position. The distributed on the circumference brackets can be arranged symmetrically or asymmetrically depending on Tragringform and serve as points of attack for such a quick-fastening device. The resulting lever system is adapted to the clamping distances and ensures the secure hold of the vessel even in tilting positions. The snap closure can also be easily and safely pressed into the closed position or the release position with a manually attached hydraulic handling device. Consequently, the same auxiliary device can be used for opening. It is first moved out of the dead center until the open position is reached.
Im einzelnen ist vorgesehen, dass der Klappverschluss aus einem die Gefäß-Konsole umgreifenden Spannbügel besteht, der schwenkbar an einem Betätigungshebel drehgelagert ist, wobei der Betätigungshebel mit seinem oberen Ende schwenkbar an der Tragring-Konsole drehgelagert ist. Dadurch entsteht auch nur ein geringer Aufwand pro Befestigungsstelle.In detail, it is provided that the snap closure consists of a vessel console encompassing clamping bracket which is pivotally mounted on an actuating lever, wherein the actuating lever with its upper End is pivotally mounted rotatably on the support ring console. This results in only a small effort per attachment point.
Diese Gestaltung ist dahingehend weiterentwickelt, dass in Schließrichtung der Spannbügel die Gefäß-Konsole umgreift und an der äußeren Umfangsfläche des Tragrings anliegt und dass der Betätigungshebel mit Verriegelungsbolzen verrastet ist, die beidseitig am Spannbügel angeordnet sind. Das Zurückdrücken des Betätigungshebels an den Tragring bewirkt ein Wegschwenken vom Tragring und gibt die Gefäß-Konsole zum Ausbau des Gefäßes frei. Ein solcher Betätigungsmechanismus spart die sonst üblichen Unterlegelemente mit sphärischem Sitz und das entsprechende Hantieren mit den Bauteilen. Für das Bedienungspersonal ist nur ein geringer Kraftaufwand und ein zeitlich relativ kurzer Zugang zum Schnellwechsel-Befestigungssystem erforderlich.This design is further developed so that in the closing direction of the clamping bracket surrounds the vessel console and rests against the outer peripheral surface of the support ring and that the actuating lever is latched with locking bolts, which are arranged on both sides of the clamping bracket. The pushing back of the actuating lever to the support ring causes a pivoting away from the support ring and releases the vessel console for removal of the vessel. Such an actuating mechanism saves the usual underlay elements with a spherical seat and the corresponding handling of the components. For the operator, only a small amount of force and relatively short time access to the quick-change attachment system is required.
Die Freigabe des Gefäßes kann auf einfache Weise dadurch erzielt werden, dass während einer Öffnungsbewegung des Betätigungshebels von der Umfangsfläche des Tragrings nach außen der Spannbügel über die Gefäß-Konsole bis in eine Offenstellung schwenkbar ist.The release of the vessel can be achieved in a simple manner, that during an opening movement of the actuating lever from the peripheral surface of the support ring to the outside of the clamping bracket on the vessel console is pivotable into an open position.
Die Anordnung ist dabei derart getroffen, dass die Gefäß-Konsole im Seitenprofil eine untere Ausnehmung bildet, in der die Tragring-Konsole mit lichtem Abstand Platz findet. Dadurch wird sehr wenig Raum verbraucht.The arrangement is made such that the vessel console in the side profile forms a lower recess in which the support ring console with clear space fits. This consumes very little space.
Die Anzahl von Gefäß-Konsolen und Tragring-Konsolen kann sich nach der Form des Tragrings ( ob Vollring oder Teil-Ring) richten. Außerdem kann der Klappverschluss auf dem Obergurt, außen oder im Abstand zwischen Tragring und Gefäß angeordnet sein.The number of vessel brackets and support ring brackets may vary depending on the shape of the support ring (whether full or partial ring). In addition, the flap closure can be arranged on the top flange, outside or at a distance between the support ring and the vessel.
Alternativen für die Ausführung ergeben sich zunächst dadurch, dass die Gefäß-Konsole aus zwei seitlich mit fest bestimmtem Abstand angeordneten Konsolplatten besteht.Alternatives for the execution initially result from the fact that the vessel console consists of two laterally arranged with a fixed certain distance console plates.
Eine zweite alternative Ausführungsform besteht darin, dass die Gefäß-Konsole aus einer einzelnen, entsprechend dick bemessenen Konsolplatte besteht.A second alternative embodiment is that the vessel console consists of a single, correspondingly thick sized console plate.
Analog zu diesen beiden Gestaltungen besteht die Tragring-Konsole aus einer einzigen, entsprechend bemessenen Konsolplatte.Analogous to these two designs, the support ring console consists of a single, appropriately sized console plate.
Die zugehörigen Hebel-Systeme sind nach einer Weiterbildung derart gestaltet, dass der Spannbügel aus zwei beabstandeten, parallelen Spannlaschen besteht, die an ihren Enden mittels eines quer verlaufenden, Distanzelementes verbunden sind, oder mit beabstandeten Tragring-Konsolplatten drehbar verbunden sind, wobei in einer mittigen, dicken Tragring-Konsole das Distanzelement Hebellaschen für den Betätigungshebel aufnimmt und dessen Drehlagerung bildet. Daraus ergeben sich nicht nur mehrere alternative Bauweisen, sondern auch eine wirtschaftliche Herstellung der Bauteile.The associated lever systems are designed according to a development in such a way that the clamping bracket consists of two spaced, parallel clamping straps which are connected at their ends by means of a transverse, spacer element, or are rotatably connected to spaced support ring-Konsolplatten, wherein in a central , thick support ring console, the spacer element lever tabs for the actuating lever receives and forms the pivot bearing. This not only results in several alternative designs, but also an economical production of the components.
Analog zur Gestaltung des Spannbügels besteht der Betätigungshebel aus zwei beabstandeten, parallelen Hebellaschen, die, die Drehlagerung bildend, mittels quer verlaufenden Distanzelementen verbunden sind.Analogous to the design of the tension bow, the actuating lever consists of two spaced, parallel lever tabs which, forming the pivot bearing, are connected by means of transverse spacer elements.
Eine andere Ausführungsform sieht vor, dass ein Spannelement aus einer zwischen den beabstandeten, parallelen Gefäß-Konsolen bzw. zwischen beabstandeten Tragring-Konsolplatten verlaufenden Spannhebelstange mit einem auf diesen aufliegenden Hammerkopf gebildet ist, die an die, die beiden Hebellaschen verbindende Drehlagerung angeschlossen ist und zwischen zwei Tragring-Konsolplatten verläuft.Another embodiment provides that a clamping element is formed of a running between the spaced, parallel vessel brackets or between spaced support ring console plates tension lever rod with a resting on this hammer head, which is connected to the, connecting the two lever brackets pivot bearing and between two support ring console plates runs.
Nach anderen Merkmalen ist vorgesehen, dass die Spannhebelstange, zwischen zwei Tragring-Konsolplatten verlaufend, die Gefäß-Konsole umgreifend einen ovalen, geschlossenen Spannbügel bildet.According to other features it is provided that the tension lever rod extending between two support ring console plates, the vessel console encompasses an oval, closed clamping bracket forms.
