Abstract
Description
Die Erfindung betrifft einen Prozessbehälter mit Kühlelementen und mit mindestens einer auf der Innenseite eines metallischen Behältermantels aufgebrachten feuerfesten Auskleidungsschicht, wobei jedes Kühlelement aus einer Basisplatte und mindestens einem, mit dieser wärmeleitend verbundenen Kühlkanal besteht, dessen Enden jeweils eine Verbindungsanordnung für den Anschluss an den Kühlkanal eines benachbarten Kühlelementes aufweisen.The invention relates to a process container with cooling elements and with at least one applied on the inside of a metallic container shell refractory lining layer, each cooling element consists of a base plate and at least one, with this heat conducting connected cooling channel, whose ends each have a connection arrangement for connection to the cooling channel of have adjacent cooling element.
Die feuerfesten Auskleidungen metallurgischer Behälter müssen beständig sein gegenüber der Einwirkung flüssiger Schmelzen und Schlacken und außerdem isolierend wirken, so dass der Behältermantel kühl genug und somit ausreichend tragfähig bleibt. Der oft erhebliche Verschleiß der Auskleidungen kann durch ihre Kühlung verringert werden.The refractory linings of metallurgical containers must be resistant to the action of liquid melts and slags and also have an insulating effect, so that the container jacket remains cool enough and thus sufficiently stable. The often considerable wear of the linings can be reduced by their cooling.
Für elektrische Schmelzöfen sind Kühlelemente bekannt, die einen wesentlichen statischen Bestandteil der Behälterwandkonstruktion bilden, indem sie verhältnismäßig große, steife Plattenelemente darstellen und in festem Verbund mit der unmittelbar auf ihrer Innenseite aufgebrachten feuerfesten Auskleidungsschicht stehen. Beispiele solcher Kühlelemente sind in den
Die häufig angewandte Kühlung der Behälterwand durch eine äußere Wasserberieselung hat den Nachteil von Wasserverlusten und Ablagerung von Kalk und Verunreinigungen. Es ist auch bekannt, auf den Behältermantel Kühlrohre aufzuschweißen. Dadurch können jedoch im Behältermantel Risse entstehen, durch die Kühlwasser in die Auskleidungsschicht eindringt.The often used cooling of the container wall by an external Wasserberieselung has the disadvantage of water losses and deposition of lime and impurities. It is also known to weld on the container jacket cooling tubes. As a result, however, cracks can occur in the container casing, through which cooling water penetrates into the lining layer.
Der Erfindung liegt die Aufgabe zugrunde, einen Prozessbehälter der eingangs genannten Art zu finden, der mit verhältnismäßig geringem Aufwand und damit kostengünstig auch durch Nachrüsten eines vorhandenen Prozessbehälters herstellbar ist und der durch eine Verringerung des Verschleißes seiner feuerfesten Auskleidung einen längeren Betrieb bis zur nächsten Reparatur der Auskleidung ermöglicht.The invention has for its object to find a process container of the type mentioned, which can be produced with relatively little effort and thus cost by retrofitting an existing process container and by reducing the wear of its refractory lining a longer operation until the next repair Lining allows.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, dass die Kühlelemente durch Schraubverbindungen mit jeweils einem an den Behältermantel außen angeschweißten Gewindebolzen außen am Behältermantel befestigt sind, so dass sie sich unter dem Spanndruck der Schraubverbindungen durch Biegeverformung an diesen anschmiegen.The solution of this object is achieved according to the invention in that the cooling elements are fastened by screw, each with a welded exterior to the container shell threaded bolt outside the container shell, so that they cling to the latter under the clamping pressure of the screw through bending deformation.
Der metallische Behältermantel eines metallurgischen Prozessbehälters wird in jedem Fall von der theoretisch idealen Form z.B. Zylinderform abweichen. Die Imperfektionen des unbelasteten, neuen Bauteils sind meist noch recht klein. Wird der Behältermantel aber durch die Prozesswärme erhitzt so dehnt er sich aus. Da die Manteltemperatur durch unterschiedliche Wärmezufuhr und/oder -Abfuhr z.B. durch einseitige Anströmung durch Wind oder durch Ablagerung von Staub auf einzelnen Zonen nicht gleichmäßig ist, sind die Dehnungen über den Umfang unterschiedlich. Der Mantel wird so zwangsläufig von der theoretischen z.B. Zylinderform abweichen. Besonders groß können lokale Aus- oder Einbuchtungen werden, wenn begrenzte Schäden an der feuerfesten Auskleidung eine starke lokale Überhitzung zur Folge haben. Während die herstellungsbedingten Imperfektionen in der Größenordnung von 1/1000 z.B. des Manteldurchmessers sind, findet man bei Behältern nach mehrjährigem Betrieb Formabweichungen im Bereich von 1/100 des Durchmessers. Weitere Ursachen für solche Verformungen des Mantels eines Prozessbehälters können sein: Gewichtsbelastung durch die Schmelze, Last durch Schwerpunktsverlagerung z.B. beim Kippen des Gefäßes zum Entleeren der Schmelze und/oder Stützkräfte die durch Dehnung der feuerfesten Auskleidung von innen auf den Mantel einwirken.The metallic container casing of a metallurgical process container will in any case deviate from the theoretically ideal shape, for example cylindrical form. The imperfections of the unloaded, new component are usually still quite small. However, if the container jacket is heated by the process heat, it expands. Since the jacket temperature is not uniform due to different heat supply and / or removal, for example due to unilateral wind flow or due to deposition of dust on individual zones, the strains are different over the circumference. The mantle will inevitably deviate from the theoretical eg cylindrical shape. Localized bulges or indentations can become particularly large if limited damage to the refractory lining results in excessive local overheating. While the production-related imperfections in the order of 1/1000, for example, the jacket diameter, can be found in containers after several years of operation form deviations in the range of 1/100 of the diameter. Further Causes of such deformations of the jacket of a process container may be: weight load through the melt, load by center of gravity displacement, for example when tilting the vessel to empty the melt and / or supporting forces acting on the jacket by stretching the refractory lining from the inside.
Schließlich ist auch die Dehnungen und Formänderungen eines metallischen Ofenmantels bei der Inbetriebnahme und bei der Stillsetzung eines Ofens zu berücksichtigen, die durch die hohe Betriebstemperatur bedingt sind. Die anhand des Ausführungsbeispiels beschriebene Kühlvorrichtung ist geeignet, sich derartigen Formänderungen anzupassen und dabei den hohen Oberflächentemperaturen beispielsweise eines Schmelzofens für die Bleiraffination zu widerstehen.Finally, the expansions and changes in shape of a metallic furnace shell during commissioning and in the shutdown of a furnace to be considered, which are due to the high operating temperature. The cooling device described with reference to the embodiment is suitable for adapting to such changes in shape and thereby withstanding the high surface temperatures of, for example, a reflow furnace for lead refining.

Der stehend oder liegend angeordnete, beispielsweise zylindrische Prozessbehälter 1 hat einen aus Stahl geformten Behältermantel 2, der gegenüber einem hocherhitzten Behälterinhalt, z.B. einer Metallschmelze durch feuerfeste Auskleidungsschichten 3,4 geschützt ist. Um die Widerstandsfähigkeit der Auskleidungsschichten 3,4 und den Schutz des Behältermantels 2 gegen Überhitzung zu erhöhen, sind an der Außenseite des Behältermantels 2 zahlreiche gleichartig ausgeführte Kühlelemente 5,5',5" befestigt.The standing or lying arranged, for example
Jedes Kühlelement 5,5',5", von denen auf einem Prozessbehälter 1 mit einem Durchmesser von beispielsweise 3 m und einer Länge von beispielsweise 25 m sowohl in Umfangsrichtung als auch in Längsrichtung z.B. jeweils zwanzig nebeneinander angeordnet sind, besteht im Wesentlichen aus einer verhältnismäßig dünnen und dadurch biegsamen Basisplatte 6, mit einer Dicke von weniger als 5 mm und vorzugsweise 3 oder 4 mm und mindestens einem, mit dieser wärmeleitend verbundenen Kühlkanal 7.Each
Der Kühlkanal 7 erstreckt sich mit mehreren, beispielsweise drei Gängen 8,9,10 und verbindenden 180°-Krümmungen schlangenförmig oder serpentinenartig gekrümmt entlang der dem Behältermantel 2 abgekehrten Außenseite der Basisplatte 6 über einen möglichst großen Teil ihrer Oberfläche, um mit dieser auf großer Oberfläche in wärmeleitendem Kontakt zu stehen. Er hat beispielsweise die schalenförmige Querschnittsform eines hälftig aufgeschnittenen Rohres, das entlang seiner Querschnittsenden mit der Basisplatte 6 verschweißt ist, so dass die Basisplatte 6 einen Teil des Kanalquerschnittes bildet. Es können jedoch auch andere Querschnittsformen gewählt werden, wofür Beispiele durch die genannte
Für den Anschluss an den Kühlkanal 7 eines benachbarten Kühlelementes 5,5',5 haben die beiden Enden 11,12 des Kühlkanals 7 jeweils eine Verbindungsanordnung, die aus einem von dem Kühlelement 5,5',5" bzw. vom Prozessbehälter 1 weg nach außen gerichteten, gekrümmten Anschlussstutzen 13,14 mit einem Endflansch 15,16 und aus einem die Anschlussstutzen 13,14 benachbarter Kühlelemente 5,5',5" verbindenden, Endflansche 17,18 aufweisenden Kompensationsrohr 19 besteht. Dieses hat einen Wellrohrbereich 20, so dass es Ungenauigkeiten der Zuordnung zwischen benachbarten Kühlelementen 5,5',5" und Wärmedehnungen im Behältermantel 2 kompensieren kann.For the connection to the
Eine lösbare Befestigung der Kühlelemente 5,5',5" erfolgt mittels zahlreicher, an der Außenseite des Behältermantels 2 aufgeschweißter Gewindebolzen 21, die sich durch mehrere in der Basisplatte 6 an entsprechenden Positionen vorgesehene Basisplatte 6 an entsprechenden Positionen vorgesehene Bolzenlöcher 22 erstrecken und außerdem entlang der Ränder 27,28 der Basisplatte 6 in einem Spaltraum zwischen benachbarten Kühlelementen 5,5',5" vorgesehen sind. Ein jeweils auf sie aufgestecktes Druckstück 23, das erheblich breiter ist als die Bolzenlöcher 22 sowie eine Tellerfeder 24 werden durch eine Schraubenmutter 25 verspannt, so dass jede Basisplatte 6 mit elastischer Vorspannung an zahlreichen Stellen entsprechend der Größe des Druckstückes 23 gegen den Behältermantel 2 angedrückt wird und durch Biegeverformung sich an die Oberflächenform des Behältermantels 2 anschmiegt. Diese Verformbarkeit der Basisplatte 6 gewährleistet eine gute Anpassung an Unregelmäßigkeiten der Oberfläche des Behältermantels 2, die herstellungsbedingt sind und sich außerdem durch die Erwärmung des Prozessbehälters und seine Chargierung ergeben, so dass ein umfangreicher wärmeübertragender Kontakt der Kühlelemente 5,5',5" mit dem Behältermantel 2 gewährleistet ist.A releasable attachment of the
Für eine weitere Verbesserung der Wärmeübertragung vom Behältermantel 2 auf die Basisplatte 6 der Kühlelemente 5,5',5" und damit an die in den Kühlkanälen 7 zirkulierende Kühlflüssigkeit ist in bevorzugter Ausführungsform der Erfindung zwischen der Behälterwand 2 und der Basisplatte 6 der Kühlelemente 5,5',5" eine Wärmeleitpaste vorgesehen, durch die Luftspalte verhindert bzw. ausgefüllt werden, die trotz der relativ guten Anschmiegbarkeit der Kühlelemente 5,5',5" an die Behälterwand 2 unvermeidlich wären. Die plastische Verformbarkeit der Wärmeleitpaste gewährleistet eine Anpassung an Form- bzw. Größenveränderungen der ausgefüllten Spalte in Folge der genannten, sich beim Betrieb des Prozessbehälters ergebenden relativen Verformungen zwischen der Basisplatte 6 und der Behälterwand 2. Hierzu trägt auch die elastische Vorspannung der Schraubbefestigung bei, die durch die genannten Tellerfedern 24 erzielt wird.For a further improvement of the heat transfer from the
Zum Nachfüllen oder auch zum Einbringen einer durch verschiedene Hersteller auf dem Markt erhältlichen Wärmeleitpaste zwischen den Behältermantel 2 und die jeweilige Basisplatte 6 sind in der Basisplatte 6 an mehreren Stellen Gewindelöcher 25 vorgesehen, in denen der Nippel einer Pastenpresse angeschlossen werden kann.For refilling or for introducing a commercially available from various manufacturers thermal paste between the
Das Einbringen der Wärmeleitpaste hinter die Basisplatte 6 der Kühlelemente 3,3',3" erfolgt beispielsweise so lange, bis sie an Rändern der Basisplatte 6 austritt. Ein Hervorquellen von Wärmeleitpaste an Rändern der Basisplatte 6 kann jedoch auch verhindert oder auf ausgesuchte Stellen begrenzt werden, indem die Basisplatte 6 entlang ihrer Ränder abgedichtet wird. Hierzu eignet sich z.B. eine aushärtende Wärmeleitpaste 30,31, die außen entlang der Ränder der Basisplatte 6 aufgebracht wird und dabei auch den Spaltraum 31 zwischen benachbarten Kühlelementen 5,5',5" ausfüllen kann. Die Abdichtung entlang der Ränder der Basisplatte 6 gestattet auch die Verwendung einer weniger zähen und hinsichtlich ihrer Wärmeleiteigenschaft optimierten Wärmeleitpaste zwischen dem Behältermantel 2 und der Basisplatte 6 der Kühlelemente 5,5',5".The introduction of the thermal paste behind the
