Description

Die Erfindung betrifft einen kippbaren Konvert.er mit eirem das Konvertergefäß im Abstand umgebenden Tragring , welcher zwei diametral gegenüberliegende Tragzapfen aufweist, Wobei das Konvertergefäß mit dem Tragring durch Zug und Druck aufnehmende Verbindungsmittel beweglich verbunden ist.The invention relates to a tiltable converter with a support ring surrounding the converter vessel at a distance, which has two diametrically opposed support pins, the converter vessel being movably connected to the support ring by means of tension and pressure-absorbing connecting means.

An die Aufhängung eines Konvertergefäßes im Tragring werdes eine Reihe von Anforderungen gestellt: In erster Linie muß die Aufhängung Verformungen des Gefäßes sowie des Tragringes zulassen. Solche Verformungen, wie sie infolge der Einflüsse des metallurgischen Betraches und der statischer Belastungen auftreten, durfon bicht behinders verden de sonst Zwangskräfte zwischen Konverter und Tragring auftreten. Eine Weitere Forderung an eine Konverteraufhänguno ist die, daß zwischen dem Konvertergefäß und deß Tragring kein eine Relativbewegung dieser beiden Teile zulassendes Spiel vorhanden sein darf, da ein solches Spiel während des Kippens des Konverters Stöce and damit unkontrollierte Beanspruchungen der lastaufnehmenden Verbindungsmittel der Aufhängung verursachen würde.A number of requirements are placed on the suspension of a converter vessel in the support ring: First of all, the suspension must permit deformation of the vessel and of the support ring. Such deformations, as they occur as a result of the influences of the metallurgical view and the static loads, durfon bicht behinders verden de, otherwise, constraining forces occur between the converter and the support ring. A further requirement for a converter suspension is that there must be no play permitting a relative movement of these two parts between the converter vessel and the support ring, since such play would cause Stöce during the tilting of the converter and thus uncontrolled stresses on the load-bearing connection means of the suspension.

Weiters sollen die den Verformungen des Konverters bzw. Tragringes entgegenwirkenden Reibungskräfte nur gering sein. Auch sollen die lastaufnehmenden Elemente möglichst einfach zu konstruieren und einfach zu dimensionieren sein, d.h. mit anderen Worten, die Berechnung der an der Aufhängung auftretenden Kräfte soll mit größtmöglicher Genuaigkeit durchgeführt werben könne.Furthermore, the frictional forces counteracting the deformations of the converter or support ring should be only slight. The load-bearing elements should also be as possible simple to construct and easy to dimension, in other words, the calculation of the forces occurring on the suspension should be carried out with the greatest possible accuracy.

Ein Konverter der eingangs beschriebenen Art ist aus der DE-AS 1 946 892 bekannt, wobei zur Aufhängung des Konvertergefäßes im Tragring im Bereich eines Tragzapfens ein Kugeln gelenk angeordnet ist, welches den Tragring unmittelbar mit dem Konvertergefäß verbindet. Dieses Kugelgelenk wirkt zur Aufnahme der horizontalen Kräfte mit einer waagrecht angeordneten, an ihren Enden mit Kugelgelenken versehenen Zugstange und zur Aufnahme der vertikalen Kräfte mit senkrechten Zugstangen zusammen. Zwar wird durch diese bekannte Konverteraufhängung der Verformung des Konverters nur ein geringer Widerstand entgegengesetzt, jedoch sind insgesamt vier Lastaufnahmeelemente notwendig, was um ein Lastelement mehr ist als für eine statisch bestimmte Dreipunktaufhängung des Konvertergefäßes im Tragring notwendig ist. Außerdem ist trotz der vier Lastaufnahmeelemente eine Dreipunktlagerung nicht in jeder Lage des Konverters gewährleistet.A converter of the type described in the opening paragraph is known from DE-AS 1 946 892, a ball joint being arranged in the support ring in the region of a support pin for suspending the converter vessel and connecting the support ring directly to the converter vessel. This ball joint cooperates with a horizontally arranged pull rod with ball joints at its ends to absorb the horizontal forces and with vertical pull rods to absorb the vertical forces. Although only a slight resistance is opposed to the deformation of the converter by this known converter suspension, a total of four load-bearing elements are necessary, which is one more load element than is necessary for a statically determined three-point suspension of the converter vessel in the support ring. In addition, despite the four load-bearing elements, three-point support is not guaranteed in every position of the converter.

Die Erfindung stellt sich die Aufgabe, einen Konverter zu schaffen, dessen Aufhängung nebst der Erfüllung sämtlicher oben angegebener Anforderungen weiters noch die Bedingung erfüllt, daß durch eine Dreipunktlagerung in jeder Lage des Konverters einerseits die statische Bestimmtheit der Auflagerung sichergestellt und anderseits die Dimensionierung, d.h. die Festigkeitsberechnung vereinfacht und die Anfälligkeit des Konverters gegen durch die Aufhängung bedingte mechanische Störungen verringert wird.The object of the invention is to create a converter whose suspension, in addition to fulfilling all of the above-mentioned requirements, also fulfills the condition that on the one hand the static determination of the support is ensured by a three-point bearing in every position of the converter and on the other hand the dimensioning, i.e. the strength calculation is simplified and the susceptibility of the converter to mechanical disturbances caused by the suspension is reduced.

Diese Aufgaben werden dadurch gelöst, daß das Konvertergefäß in dem Tragring mittels dreier zur Längsachse des Konvertergefäßes geneigter Gelenklaschen gelagert ist deren Gelenke jeweils an dem Konvertergefäß und am Tragring montiert sind, wobei die Gelenklaschen in der durch ihre Längs- bzw. Mittelachse und die Längsachse des Konvertergefäßes gebildeten Ebene schwenkbar sird. Dabei liegt zweckmäßig die Neigung der Gelenklaschen zur Längsachse des Konvertergefäßes in einem Winkelbereich zwischen 15° und 45°.These objects are achieved in that the converter vessel is mounted in the support ring by means of three articulated brackets inclined to the longitudinal axis of the converter vessel the joints of which are each mounted on the converter vessel and on the support ring, the link plates being pivotable in the plane formed by their longitudinal or central axis and the longitudinal axis of the converter vessel. In this case, the inclination of the link plates to the longitudinal axis of the converter vessel is expediently in an angular range between 15 ° and 45 °.

Eine bevorzugte Neigung der Längsachsen jeder Gelenklasche zur Längsachse des Konverters beträgt 30°.A preferred inclination of the longitudinal axes of each link plate to the longitudinal axis of the converter is 30 °.

Nach einer bevorzugten Ausführungsform ist jede Gelenklasche an einem Ende mit einem einzigen Schwenklager und am anderen Ende mit zwei in Umfangsrichtung des Konverters bzw. des Tragringes im Abstand voneinander befindlichen Schwenklagern ausgestattet, wobei die nur ein Schwenklager aufweisenden Enden sämtlicher Gelenklaschen entweder dem Tragring oder dem Konverter zugeordnet sind und wobei zweckmäßig die Lager der Gelenklaschen als Gelenklager ausgebildet sind.According to a preferred embodiment, each link plate is equipped at one end with a single pivot bearing and at the other end with two pivot bearings spaced apart in the circumferential direction of the converter or the support ring, the ends of all the link plates having only one pivot bearing either the support ring or the converter are assigned and the bearings of the articulated straps are expediently designed as articulated bearings.

Bei Anordnung von zwei im Abstand voneinander befindlichen Lagern an dem Ende einer Gelenklasche ist vorteilhaft ein Lager als Fest- und das andere als Loslager ausgebildet.When two spaced-apart bearings are arranged at the end of an articulated bracket, one bearing is advantageously designed as a fixed bearing and the other as a floating bearing.

Eine besonders zweckmäßige Anordnung der Gelenklaschen ist dadurch gekennzeichnet, daß die Längsachsen aller Gelenklaschen in einer durch die Längsachse des Konvertergefäßes und zur Achse der Tragzapfen rechtwinkelig gelegten Ebene liegen, wobei vorteilhaft zwei der Gelenklaschen unterhalb und eine Gelenklasche oberhalb des Tragringes des in aufrechter Position befindlichen Konvertergefäßes angeordnet sind.A particularly useful arrangement of the link plates is characterized in that the longitudinal axes of all link plates lie in a plane perpendicular to the longitudinal axis of the converter vessel and to the axis of the trunnion, advantageously two of the link plates below and one link plate above the support ring of the converter vessel located in the upright position are arranged.

Die Brfindung ist anhand der Beishnung an mehreren Ausführungsbeispielen näher erläntutert, wobei Fig. 1 eine Vorderansicht eines Konverters, Fig. 2 eine Ansicht in Richtung des Pfeiles II der Fig. 1 teilweise im Schnitt und Fig. 3 eine Ansicht in Richtung des Pfeiles III der Fig. 1 ebenfalls teilweise im Schnitt zeigen. Die Fig. 4 und 5 sowie 7 und 8 veranschaulichen zwei weitere Ausführungsformen in zu den Fig. 1 und 2 analogen Darstellungen. Fig. 6 zeigt eine Gelenklasche der in den Fig. 4 und 5 dargestellten Ausführungsform im Schrägriß.The invention is explained in more detail with the aid of several exemplary embodiments, with FIG. 1 a front view of a converter, FIG. 2 a view in the direction of arrow II in FIG. 1, partly in section, and FIG. 3 a view in the direction of arrow III in FIG Fig. 1 also partially show in section. 4 and 5 and 7 and 8 illustrate two further embodiments in representations analogous to FIGS. 1 and 2. Fig. 6 shows a link plate of the embodiment shown in Figs. 4 and 5 in oblique view.

Mit 1 ist das Konvertergefäß bezeichnet welches von einem geschlossenen.Tragring 2 umgeben ist. Der Tragring 2 ist mittels zweier miteinander fluchtender Tragzapfen 3 in nicht dargestellten Stützlagern kippbar gelagert.The converter vessel is designated by 1 and is surrounded by a closed support ring 2. The support ring 2 is tiltably supported by two aligned support pins 3 in support bearings, not shown.

Die Befestigung des Konvertergefäßes 1 in dem Tragring 2 erfolgt mittels dreier Gelenklaschen 4, die jeweils sowohl am Tragring 2 als auch am Konvertergefäß 1 schwenkbeweglich in Lagern 5,6 gelagert sind. Sowohl die Lager 6, die am Tragring vorgesehen sind, als auch die Lager 5 am Konvertergefäß sind zweigeteilt ausgebildet, wobei jede Gelenklasche mit an ihren Enden vorgesehenen Bolzen 7, 8 in jeweils einem Teil 5', 5" bzw. 6', 6" der Lager 5, 6. eingesetat ist. Die Lager 6 am Konvertergefäß sind in Rippen 3 eingebaut, welche durch Gurte 10 und weitere Rippen 11 verstärkt sind.The converter vessel 1 is fastened in the support ring 2 by means of three articulated brackets 4, which are each pivotably mounted in bearings 5, 6 both on the support ring 2 and on the converter vessel 1. Both the bearings 6, which are provided on the support ring, and the bearings 5 on the converter vessel are formed in two parts, each joint plate with bolts 7, 8 provided at its ends in a part 5 ', 5 "and 6', 6", respectively. the bearing 5, 6 is budgeted. The bearings 6 on the converter vessel are installed in ribs 3, which are reinforced by belts 10 and further ribs 11.

Die Anordnung der Lager 5, 6 ist so gewählt, daß die Längs- bzw. Mittelachse 12 jeder Gelenklasche 4 mit der Längsachse 13 des Konvertergefäßes 1 etwa einen Winkel 14 von 30 einschliast, wobei die Längsachse 12 jeder Gelenklasche 4 sich mit der Längsachse 13 des Konvertergefäßes 1 schneidet, so daß die Gelenklaschen in der durch ihre Längsachse und die Längsachse des Konvertergefäßes gebildeten Ebene schwenkbar sind. Weiters liegen die Längsachsen aller Gelenklzschen in der Achse 15 der Tragzapfen 3 recha inkelig und durch die Längsachse 13 des Gefäßes gelegten Ebene, wobei eine der Celenklaschen 4 an der Oberseite des Tragringes und die beiden anderen Gelenklaschen an der Unterseite des Tragringes - bei aufrechtstehendem Konverter - angeordnet sind.The arrangement of the bearings 5, 6 is selected such that the longitudinal or central axis 12 of each link plate 4 forms an angle 14 of 30 with the longitudinal axis 13 of the converter vessel 1, the longitudinal axis 12 of each link plate 4 intersects with the longitudinal axis 13 of the converter vessel 1, so that the hinge plates can be pivoted in the plane formed by their longitudinal axis and the longitudinal axis of the converter vessel. Furthermore, the longitudinal axes of all articulation pins lie in the axis 15 of the support pins 3 recha angular and plane through the longitudinal axis 13 of the vessel, one of the Celenklaschen 4 on the top of the support ring and the other two articulation tabs on the underside of the support ring - with the converter upright - are arranged.

Diese Anordnung der Gelenklaschen, die insbesondere aus Fig. 3 besonders deutlich ersichtlich ist, bewirkt, daß sich das Konvertergefäß 1 innerhalb des Tragringes nach allen Richtungen frei ausdehnen bzw. zusammenziehen kann, wobei bei einer solchen Verformung des Konvertergefäßes lediglich Reibungskräfte in den Lagern 5, 6 auftreten. Das Gewicht des Konverters wird, wenn sich der Konverter in aufrechter Lage, wie in den Fig. 1 bis 3 dargestellt ist, befindet, mittels der beiden an der Unterseite des Tragringes 2 befindlichen Gelenklaschen 4 in den Tragring eingeleitet; beim Kippen des Konvertergefäßes tritt die dritte, an der Oberseite des Tragringes 2 angeordnete Gelenklasche 4 in Funktion.This arrangement of the link plates, which can be seen particularly clearly from FIG. 3 in particular, causes the converter vessel 1 to expand or contract freely in all directions within the support ring, with only such a deformation of the converter vessel causing frictional forces in the bearings 5. 6 occur. The weight of the converter, when the converter is in an upright position, as shown in FIGS. 1 to 3, is introduced into the support ring by means of the two joint plates 4 located on the underside of the support ring 2; when the converter vessel is tilted, the third hinge plate 4 arranged on the upper side of the support ring 2 comes into operation.

Der Ein- und Ausbau des Konvertergefäßes aus bzw. in den Tragring gestaltet sich äußerst einfach. Zum Ausbau muß lediglich an den Lagern 6, beispielsweise durch Herausschlagen der Bolzen 7 die Verbindung der Gelenklaschen'4 mit dem Konvertergefäß 1 gelöst werden, worauf die Gelenklaschen 4 in Richtung des Pfeiles 16 verschwenlt und das Konvertengefäß 1 infolge des zwischen dem Tragring und der äußersten Kontur des Konvaters vorgesehenen Spieles 17 durch Heben oder Senken aus dem Tragring 2 ausgefädelt werden kann.The installation and removal of the converter vessel from or in the support ring is extremely simple. To expand, the connection of the link plates 4 to the converter vessel 1 only has to be released at the bearings 6, for example by knocking out the bolts 7, whereupon the link plates 4 swings in the direction of the arrow 16 and the converter vessel 1 as a result of that between the support ring and the outermost one Contour of the convater provided game 17 can be threaded out of the support ring 2 by lifting or lowering.

Bei der in den Fig. 4 bis 6 dargestellten Ausführungsform sind die hinsichtlich ihrer Längs-(bzw. Mittel-)achse 12 gekröpft ausgebildeten Gelenklaschen 18 jeweils am Tragring 2 mittels eines Lagers 19 und am Konvertergefäß mittels zweier im Abstand voneinander befindlicher Lager 20 gelagert. Infolge des großen Abstandes der beiden am Konvertengefäß angeordneten Lager 20 schließen die Achsen 21 dieser Layer miteinander einen stumpfen Winkel ein, weshalb diese Lager 20 als Gelenklager ausgebildet sind wie in Fig. 5 schematisch, dargestellt ist. Hierdurch wird eine einwandfreie Schwenkmöglichkeit der Gelenklaschen um diese Lager 20 ermöglicht. Eines der Gelenklager 20 ist als Loslager und das andere als Festlager ausgebildet.In the embodiment shown in FIGS. 4 to 6, the articulated brackets 18, which are cranked with respect to their longitudinal (or central) axis 12, are each on the support ring 2 by means of a bearing 19 and on the converter vessel by means of two spaced apart bearings 20. As a result of the large distance between the two bearings 20 arranged on the converter vessel, the axes 21 of these layers form an obtuse angle with one another, which is why these bearings 20 are designed as spherical bearings, as shown schematically in FIG. 5. This enables a perfect pivoting possibility of the link plates around this bearing 20. One of the spherical bearings 20 is designed as a floating bearing and the other as a fixed bearing.

Eine weitere Ausführungsform ist in den Fig. 7 und 8 dargestellt, bei der jede Gelenklasche 22 am Tragring 2 mittels zweier im Abstand voneinander befindlicher Lager 23 und am Konvertergefäß mittels eines einzigen Lagers 24 gelagert ist.A further embodiment is shown in FIGS. 7 and 8, in which each joint plate 22 is mounted on the support ring 2 by means of two bearings 23 located at a distance from one another and on the converter vessel by means of a single bearing 24.

Die Erfindung beschränkt sich nicht auf die dargestellten Ausführungsformen, sondern kann in verschiedener Hinsicht modifiziert werden. So ist es möglich, die Gelenklaschen auch außerhalb der senkrecht zur Tragzapfenachse gelegten Symmetrieabene anzuordnen, beispielsweise könnten sich alle drei Gelenklaschen nur an der Oberseite oder auch nur an der Unterseite des Tragringes gleichmäßig um ihn verteilt befinden.The invention is not limited to the illustrated embodiments, but can be modified in various ways. It is thus possible to arrange the articulated brackets outside of the plane of symmetry perpendicular to the trunnion axis, for example all three articulated brackets could be evenly distributed around the upper side or only on the lower side of the supporting ring.
