Description

Die Erfindung betrifft eine Kühlvorrichtung für Elektroden eines metallurgischen Ofens, wie Reduktionsofen, Lichtbogenofen, Induktionsofen usw., die die Elektrode umschließt und aus Einzelsegmenten besteht.The invention relates to a cooling device for electrodes of a metallurgical furnace, such as reduction furnace, electric arc furnace, induction furnace, etc., which encloses the electrode and consists of individual segments.

GB-A-130 205 offenbart eine Kühlvorrichtung für Electroden die mit Schorniere zu mindestens zwei Schilde verbunden ist. GB-A-130 205 discloses a cooling device for electrodes which is connected with chimneys to at least two shields.

Aus der DE 31 48 606 A1 ist ein Verfahren zur Erleichterung des Wartens und Auswechselns der Kontaktbacken von Lichtbogenofen - Elektroden bekannt. Dabei wird das Unterteil des aus zwei lösbar miteinander verbundenen Teilen bestehenden Tragmantels der Kontaktbacken teleskopartige auf das Oberteil gehoben, wodurch die am Unterteil befestigten Kontaktbacken an eine Stelle oberhalb des Ofengewölbes gebracht werden. Weiterhin ist eine entsprechende Vorrichtung beschrieben.From the DE 31 48 606 A1 A method for facilitating the maintenance and replacement of the contact jaws of electric arc furnace electrodes is known. In this case, the lower part of the two releasably interconnected parts existing support jacket of the contact jaws is lifted telescopically on the upper part, whereby the attached to the lower part of the contact jaws are brought to a point above the furnace vault. Furthermore, a corresponding device is described.

In der DE 36 30 861 C2 ist eine Elektrodentieffassung für Elektrolichtbogen- oder Reduktionsöfen bekannt, mit mehreren durch den Ofendeckel geführten Elektroden, mit konzentrisch zu den einzelnen Elektroden angeordneten, zylindrischen Kapseln und mit Stromzuführungseinrichtungen, die auf einem Teil ihrer Länge als Stromrohre parallel zu der Elektrode mit ihren Achsen auf einem zur Elektrode konzentrischen Zylinder verlaufen und dabei nur einen Teil des Zylinderumfanges einnehmen und an deren dem Ofengefäßboden zugewandten Ende an die Elektroden anpressbare Kontaktbacken angeordnet sind. Dabei weist jede Kapsel mindestens zwei Manteldurchbrüche auf, die sich jeweils über einen Teil des Umfangs in ihrer Breite erstrecken. In diesen Manteldurchbrüchen sind die koaxial zur Kapsel geführten Stromrohrstücke der Stromzuführungseinrichtung angeordnet und durch Einbetten, Umgießen oder dgl. zu Teilen vereinigt, die die Manteldurchbrüche im Wesentlichen abschließen. Jeweils zwei Manteldurchbrüche benachbarter Kapseln sind einander zugewandt.In the DE 36 30 861 C2 is known Elektrodentieffassung for electric arc or Reduktionsöfen, with a plurality of guided through the furnace lid electrodes, arranged concentrically with the individual electrodes, cylindrical capsules and with power supply devices, which are part of their length as power tubes parallel to the electrode with their axes on a for Lead electrode concentric cylinder and occupy only a portion of the cylinder circumference and are arranged at the furnace vessel bottom facing the end to the electrodes contactable contact jaws. In this case, each capsule has at least two shell openings, which each extend over a part of the circumference in its width. In these jacket openings the coaxial with the capsule guided power pipe sections of the power supply device are arranged and united by embedding, Umgießen or the like. To parts that substantially complete the shell openings. Two jacket openings each of adjacent capsules face each other.

Eine Elektroden - Tieffassung für Lichtbogen- oder Reduktionsöfen wird in der DE 21 25 773 C3 beschrieben. Dabei werden die im Ofenbereich liegenden Stromzuführungsteile, insbesondere Stromleiter, Fassungsteile und dergleichen, durch einen doppelwandigen, wassergekühlten, zur Elektrode koaxial angeordneten Kühlmantel geschützt. Der Kühlmantel reicht bis zum gekühlten Fassungsring und ist von diesem lösbar. Der Kühlmantel wird durch eine quer zu seiner Achse verlaufenden Ebene in einen oberen zylindrischen und einen unteren zylindrischen Teil unterteilt. Der untere Teil ist in miteinander lösbar verbundene, kühlmitteldurchströmte segmentartige Kühlschilde unterteilt.An electrode base for arc or reduction furnaces is disclosed in US Pat DE 21 25 773 C3 described. In this case, lying in the oven area power supply parts, especially conductors, socket parts and the like, protected by a double-walled, water-cooled, coaxially arranged to the electrode cooling jacket. The cooling jacket extends to the cooled mounting ring and is detachable from this. The cooling jacket is divided by a transverse plane to its axis in an upper cylindrical and a lower cylindrical portion. The lower part is subdivided into interconnected, coolant-flowed segment-like cooling shields.

Auf diese Weise wird die Elektrode unterhalb einer Gasabzugshaube bis zu den Stromführungsbacken von der Kühlvorrichtung umschlossen. Die abnehmbaren Kühlschilde ermöglichen einen leichten Zutritt zu der Klemmvorrichtung bzw. den Stromführungsbacken bei der Instandhaltung.In this way, the electrode is enclosed below a gas exhaust hood up to the current-carrying jaws of the cooling device. The removable cooling shields allow easy access to the clamping device or the current-carrying jaws during maintenance.

Die Kühlschilde müssen hierzu einzeln ausgebaut werden, durch Schrauben lösen, Bolzen ziehen, Hebevorrichtung oder ähnliches benutzen usw. Dieses zeitaufwändige Verfahren beeinträchtigt die Produktion, das der Ofen im Conti - Betrieb läuft und eine Verfügbarkeit von ca. 97 % pro Jahr aufweist. Beim Lösen und Abnehmen der Kühlschilde kann es außerdem zu Schäden an den wasserführenden Teilen kommen.The cooling shields have to be removed individually, loosened by screws, pull bolts, use lifting device or similar, etc. This time - consuming process affects the production, which runs the furnace in the Conti - operation and has an availability of about 97% per year. When loosening and removing the cooling shields may also cause damage to the water-bearing parts.

Der Erfindung liegt daher die Aufgabe zugrunde, die bekannte Kühlvorrichtung so zu verbessern, dass der Zugang zu der Elektrode vereinfacht wird und die oben genannten Nachteile vermieden werden. Mit einer verbesserten Ausbildung der Kühlvorrichtung soll außerdem die Verfügbarkeit des Ofens verbessert werden.The invention is therefore based on the object to improve the known cooling device so that the access to the electrode is simplified and the above-mentioned disadvantages are avoided. With an improved design of the cooling device also the availability of the furnace should be improved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einer Kühlvorrichtung gemäß dem Oberbegriff von Anspruch 1, mindestens ein Einzelsegment mit mindestens einem Scharnier ausgebildet ist.This object is achieved in that in a cooling device according to the preamble of claim 1, at least one single segment is formed with at least one hinge.

Weitere Ausgestaltungen der Kühlvorrichtung ergeben sich aus den diesbezüglichen Unteransprüchen.Further embodiments of the cooling device will become apparent from the relevant subclaims.

Die Erfindung betrifft außerdem ein Verfahren zum Verschwenken mindestens eines Einzelsegmentes.The invention also relates to a method for pivoting at least one individual segment.

Weitere Ausgestaltungen des Verfahrens ergeben sich aus den diesbezüglichen Unteransprüchen.Further embodiments of the method will become apparent from the relevant subclaims.

Der entscheidende Vorteil der erfindungsgemäßen Kühlvorrichtung liegt darin, dass das oder die Einzelsegmente durch einfaches wegschwenken von der Elektrode entfernt werden. Eine Hebevorrichtung oder dgl. wird nicht benötigt. Die Einzelsegmente müssen nicht zwischengelagert werden sondern sind beim Zugang zu der Elektrode an dieser bzw. deren Haltevorrichtungen befestigt.The decisive advantage of the cooling device according to the invention is that the one or more individual segments are removed by simply pivoting away from the electrode. A hoist or the like is not needed. The individual segments need not be stored but are attached to the access to the electrode at this or their holding devices.

Dabei wird der Kühlkreislauf aufrechterhalten indem beispielsweise der Kühlwasserzulauf und der Kühlwasserablauf über flexible Leitungen erfolgen. Diese sind so ausgelegt, dass sie den Verschwenkvorgang nicht behindern oder einschränken.In this case, the cooling circuit is maintained by, for example, the cooling water inlet and the cooling water drain via flexible lines. These are designed so that they do not obstruct or limit the pivoting process.

Die aufgezeigten Verbesserungen reduzieren die Ofenstillstandszeiten, da die Wartungszeiten verkürzt werden.The improvements shown reduce oven downtime because maintenance times are reduced.

In Figur 1 ist eine Kühlvorrichtung 1, bestehend aus mehreren Einzelsegmente 2, 3, 4, 5, dargestellt. Die Einzelsegmente 2, 3, 4, 5 sind beispielsweise einzeln an einem Hängerahmen 6 durch mindestens ein Scharnier 7 befestigt. Je nach Größe und Gewicht der Einzelsegmente 2, 3, 4, 5 können auch weitere Scharniere 7 berücksichtigt werden. Wie zu sehen ist, werden die Einzelsegmente 2, 3 durch die Scharniere 7 von der Elektrode (nicht dargestellt) weggeschwenkt.In FIG. 1 is a cooling device 1, consisting of several individual segments 2, 3, 4, 5, shown. The individual segments 2, 3, 4, 5 are, for example, fastened individually to a hanging frame 6 by at least one hinge 7. Depending on the size and weight of the individual segments 2, 3, 4, 5 and other hinges 7 can be considered. As can be seen, the individual segments 2, 3 are pivoted away from the electrode (not shown) by the hinges 7.

Dabei kann jedes Einzelsegment 2, 3, 4, 5 alleine durch ein Scharnier verschwenkt werden. Es besteht aber auch die Möglichkeit, zwei benachbarte Einzelsegmente 4, 5 durch ein oder mehrere Scharniere 8 gelenkig zu verbinden, wobei das Einzelsegment 5 durch ein Scharnier 7 mit dem Hängerahmen 6 verbunden ist. Alternativ kann das Einzelsegment 5 mittels Scharniere 8 mit einem weiteren Einzelsegment verbunden werden.In this case, each individual segment 2, 3, 4, 5 can be pivoted by a hinge alone. But it is also possible, two adjacent individual segments 4, 5 articulated by one or more hinges 8, wherein the single segment 5 is connected by a hinge 7 with the hanging frame 6. Alternatively, the single segment 5 can be connected by means of hinges 8 with a further single segment.

In Figur 2 ist in Draufsicht eine Kühlvorrichtung 1 dargestellt, bei der alle Einzelsegmente 2, 3, 4, 5 einzeln durch ein Scharnier 7 mit dem Hängerahmen 6 verbunden sind. Die Einzelsegmente 2, 3, 4, 5 sind dazu mit einem Drehgelenk 9 ausgebildet, an die das Scharnier 7 befestigt ist.In FIG. 2 is shown in plan view a cooling device 1, in which all individual segments 2, 3, 4, 5 are individually connected by a hinge 7 with the hanging frame 6. The individual segments 2, 3, 4, 5 are for this purpose formed with a rotary joint 9, to which the hinge 7 is attached.

Jedes Einzelsegment 2, 3, 4, 5 verfügt über mindestens einen Kühlwasserzulauf 10 und mindestens einen Kühlwasserablauf 11. Diese sind über flexible Leitungen (nicht dargestellt) mit einem Kühlkreislauf verbunden. Alternativ können auch zwei benachbarte Einzelsegmente 2, 3, 4, 5 einen gemeinsamen Kühlkreislauf aufweisen.Each individual segment 2, 3, 4, 5 has at least one cooling water inlet 10 and at least one cooling water outlet 11. These are connected via flexible lines (not shown) to a cooling circuit. Alternatively, two adjacent individual segments 2, 3, 4, 5 may have a common cooling circuit.

Sollen die Einzelsegmente 2, 3, 4, 5 in einem größeren Abstand zur Elektrode verschwenkt werden, so kann mindestens ein Scharniersteg 12 teleskopartig ausgebildet sein.If the individual segments 2, 3, 4, 5 are to be pivoted at a greater distance from the electrode, then at least one hinge web 12 may be formed telescopically.
