Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Kuppeln der an einer Stromversorgungsanlage angeschlossenen flexiblen Stromzuführung mit einer in einem metallurgischen Gefäß angeordneten Bodenelektrode.The invention relates to a device for coupling the flexible power supply connected to a power supply system with a base electrode arranged in a metallurgical vessel.
In der Hüttenindustrie kommen metallurgische Gefäße zum Einsatz, die mittels Gleichstrom beheizt werden. Dabei ragt regelmäßig die Kathode in das Gefäß hinein, und die Annode ist am Gefäßboden angeordnet.Metallurgical vessels that are heated by direct current are used in the metallurgical industry. The cathode regularly protrudes into the vessel and the annode is arranged on the bottom of the vessel.
Die Anode kann dabei als Einzelelektrode, z.B. als metallische Stabelektrode ausgebildet sein. Es kann aber auch die Gefäßauskleidung elektrisch leitend sein, so daß das Gefäß oder ein Teil davon die Anode bilden und der Gefäßmantel zur Stromübertragung herangezogen wird.The anode can be used as a single electrode, e.g. be designed as a metallic stick electrode. However, the vessel lining can also be electrically conductive, so that the vessel or a part thereof form the anode and the vessel jacket is used for the current transmission.
Bei einem Wechsel des metallurgischen Gefäßes oder bedingt durch den Verschleiß der Anode bei einem Wechsel der Anode ist die Stromzuführung an einem Anschlußstück zu lösen.When changing the metallurgical vessel or due to the wear of the anode when changing the anode, the power supply to a connector must be disconnected.
So ist aus der EP-OS 0 133 931 eine Schraubverbindung bekannt. In nachteiliger Weise muß das Wartungspersonal unterhalb des Gefäßes manuell die Verbindung lösen.A screw connection is known from EP-OS 0 133 931. In a disadvantageous manner, the maintenance personnel must manually disconnect the connection below the vessel.
Aus der EP-OS 0 275 384 ist bekannt, als Kontakteinrichtung federbelastete Tragbolzen vorzusehen, die die Stromzuführleitung gegen die Elektrode pressen und die beim Lösen der elektrischen Kontakte zurückziehbar sind. Die Stromkabel sind dabei an verschiebbaren Laschen befestigt, die gelenkig gelagert sind.From EP-OS 0 275 384 it is known to provide spring-loaded support bolts as the contact device, which press the power supply line against the electrode and which can be withdrawn when the electrical contacts are released. The power cables are attached to sliding tabs that are articulated.
Bei dieser Kontaktvorrichtung wirken die vom Eigengewicht der Stromzuführungsleitung herrührenden Zugkräfte auf die Bodenelektrode. Außerdem ist kein Weg zur mechanisierten Heranführung des Stromzuführkabels vorgegeben.In this contact device, the tensile forces resulting from the dead weight of the power supply line act on the base electrode. In addition, there is no way specified for the mechanized introduction of the power supply cable.
Aus der DE-PS 0 178 981 ist eine Anschlußklemme für die Elektrode eines metallurgischen Gefäßes bekannt, bei der mittels teleskopischer Arme ein die Elektrode haltender Aufhängeflansch am Mantel des Gefäßes vorgesehenen Befestigungsflansch verbunden wird. Die in den Teleskoparmen angeordneten elastischen Elemente dienen zum Ausgleich der thermischen Längenänderung der Elektrode.From DE-PS 0 178 981 a connection terminal for the electrode of a metallurgical vessel is known, in which a suspension flange provided on the jacket of the vessel holding the electrode is connected by means of telescopic arms. The elastic elements arranged in the telescopic arms serve to compensate for the thermal change in length of the electrode.
Die Elektrode wird durch Druckkräfte belastet. Die Stromzuführung ist über einen Schraubflansch an dem herausragenden Teil der Elektrode befestigt und nur manuell lösbar.The electrode is loaded by compressive forces. The power supply is attached to the protruding part of the electrode via a screw flange and can only be removed manually.
Eine hohe Betätigungsfrequenz der Kontaktvorrichtung tritt insbesondere auf bei Pfannenbehandlungsständen und bei Tundish-Beheizungsanlagen.A high frequency of actuation of the contact device occurs in particular in ladle treatment stands and in tundish heating systems.
Aus EP-OS 0 344 092 ist ein metallurgisches Gefäß mit einer Gegenelektrode bekannt, das an seiner Außenhülle ein der Übertragung der elektrischen Energie dienendes Element aufweist, das eine Fläche besitzt, die sich auf der Fläche eines Gegenelementes abstützt. Dieses Gegenelement ist mit mechanischen Mitteln positionierbar.From EP-OS 0 344 092 a metallurgical vessel with a counter electrode is known which has on its outer shell an element which serves to transmit the electrical energy and which has a surface which is supported on the surface of a counter element. This counter element can be positioned by mechanical means.
Als Nachteil ist hervorzuheben, daß beide Elemente beim Abstützen mit Druckkräften belastet sind, sei es bei vertikaler oder auch bei horizontaler Anordnung. Durch den Einsatz von mechanischen Mitteln zum Positionieren und Anpassen ist das Fixieren in der Arbeitsposition nur in engen Grenzen möglich.It should be emphasized as a disadvantage that both elements are loaded with compressive forces when they are supported, be it in a vertical or in a horizontal arrangement. Due to the use of mechanical means for positioning and adjustment, fixing in the working position is only possible within narrow limits.
Die Erfindung widmet sich dem Problem, eine Kontaktverbindung zwischen Elektrode und Stromversorgungsanlage zu schaffen, die bei einfachem Aufbau in einem weiten Bereich positionierbar ist, die ein mechanisiertes Kontaktieren zuläßt und deren Kontaktierung bei zuverlässiger Stromübertragung kraftneutral erfolgt.The invention is dedicated to the problem of creating a contact connection between the electrode and the power supply system, which can be positioned in a wide range with a simple structure, which allows mechanized contacting and whose contacting takes place in a force-neutral manner with reliable current transmission.
Die Erfindung löst dieses technische Problem gemäß der Merkmale des kennzeichnenden Teils des Hauptanspruches.The invention solves this technical problem according to the features of the characterizing part of the main claim.
Erfindungsgemäß wird der Teil der Kupplung, an dem die Stromzuführleitung angeschlossen ist, über Ausgleichselemente mit einem Tragelement verbunden. Das Tragelement kann ortsfest oder bewegbar sein. Bei einem ortsfesten Tragelement ist auch die Kupplungseinheit ortsfest, während ausschließlich das metallurgische Gefäß frei bewegbar ist. Das Tragelement kann als Arm ausgebildet sein. Der bewegbar ausgebildete Tragarm dient zur Positionierung des an ihm befestigten Kupplungsteils mit dem am metallurgischen Gefäß angeordneten Kupplungsteil.According to the invention, the part of the coupling to which the power supply line is connected is connected to a support element via compensating elements. The support element can be stationary or movable. In the case of a stationary support element, the coupling unit is also stationary, while only the metallurgical vessel can be moved freely. The support element can be designed as an arm. The movable support arm is used to position the coupling part fastened to it with the coupling part arranged on the metallurgical vessel.
Es kommen Ausgleichselemente zum Einsatz, die nach erfolgter Kupplung der drei Kupplungsteile die Gewichtskräfte der flexiblen Stromzuführung kompensieren. Durch das Trennen von Kuppeln und Führen der Stromzuführleitung wird erfindungsgemäß die Elektrode und das metallurgische Gefäß von behindernden Zug- oder Druckkräften freigehalten.Compensating elements are used that compensate the weight of the flexible power supply after the three coupling parts have been coupled. By separating domes and guiding the power supply line, the electrode and the metallurgical vessel are kept free from obstructing tensile or compressive forces.
Als wartungsarme und funktionssichere Kupplung wird eine Hülsenkupplung vorgeschlagen, die im wesentlichen aus einem Vater- und einem Mutterteil besteht. Die Verbindung dieser Teile kann zur sicheren Stromübertragung kraft- und/oder formschlüssig erfolgen. So wird in einer Ausbildungsform ein Mutterteil mit einer sich zur Mündung hin verjüngenden konischen Form vorgeschlagen. In dieses Mutterteil ist ein Vaterteil einbringbar, das in seinem vorderen Bereich im Durchmesser radial vergrößerbar ist. Während des Betriebes sind beide Teile großflächig gegeneinander preßbar.A sleeve coupling, which essentially consists of a male and female part, is proposed as a low-maintenance and functionally reliable coupling. The connection of these parts can be non-positive and / or positive for safe power transmission. In one form of training, for example, a mother part with a conical shape tapering towards the mouth is proposed. A male part can be introduced into this female part, the diameter of which can be increased radially in its front region. During operation, both parts can be pressed against one another over a large area.
In einer weiteren vorteilhaften Ausbildung sind zwischen dem Vater- und Mutterteil Stromlamellen angeordnet.In a further advantageous embodiment, current blades are arranged between the male and female parts.
Die Kupplungsteile, sei es bei einer Hülsenkupplung ein Vater- oder ein Mutterteil, lassen sich an dem metallurgischen Gefäß an beliebiger Stelle anordnen. Bei dem rauhen Hüttenbetrieb bietet sich eine vor Schmutz, Hitze und mechanischer Zerstörung geschützte Lage an. Dies wird vorzugsweise der Rand des Gefäßes sein, und zwar oberhalb - wie in der Zeichnung dargestellt - oder auch unterhalb des Bordes. Bei der genannten Alternative kann wiederum das Vaterteil oder das Mutterteil an dem Gefäß befestigt sein.The coupling parts, be it a male or female part in a sleeve coupling, can be arranged anywhere on the metallurgical vessel. A location protected from dirt, heat and mechanical destruction is ideal for the rough operation of the hut. This will preferably be the edge of the vessel, above - as shown in the drawing - or below the shelf. In the alternative mentioned, the male part or the female part can in turn be attached to the vessel.
Beim Einsatz von metallurgischen Gefäßen, die während des Betriebes einen Hub ausführen wie beispielsweise Verteilerrinnen o.ä., können steuerbare Ausgleichselemente zum Einsatz kommen. Diese Ausgleichselemente etwa in der Form von fluidbetriebenen Kolbenzylindern werden entsprechend der Erfindung so eingestellt, daß ein kraftfreies Führen im vollen Bereich des Hubes bezüglich Frequenz und Amplitude erfolgt.When using metallurgical vessels that perform a stroke during operation, such as distribution channels or the like, controllable compensating elements can be used. These compensating elements, for example in the form of fluid-operated piston cylinders, are set according to the invention in such a way that force-free guiding takes place in the full range of the stroke in terms of frequency and amplitude.
