Abstract
Description
Die Erfindung betrifft eine Feuerfestauskleidung für metallurgische Gefäße, insbesondere Stahlpfannen, bestehend aus einem der Schmelze zugewandten gegossenen Verschleißfutter und einem zwischen der inneren Pfannenwandung und dem Verschleißfutter angeordneten Dauerfutter.The invention relates to a refractory lining for metallurgical vessels, in particular steel pans, consisting of a cast wear lining facing the melt and a permanent lining arranged between the inner pan wall and the wear lining.
Bei der Herstellung von Stahl wird die erzeugte Stahlschmelze zum Transport, aber auch zur Durchführung metallurgischer Arbeiten wie Legierungseinstellung, Entschwefelung und dergleichen, in sogenannte Pfannen eingefüllt, die aus einem Stahlbehälter mit einer inneren Feuerfestauskleidung bestehen. Diese Feuerfestauskleidung unterliegt, besonders im oberen Bereich der Schlackenbildung, einem chemischen und mechanischen Verschleiß, so daß die Pfannenzustellung von Zeit zu Zeit erneuert werden muß.In the production of steel, the steel melt produced is poured into so-called pans, which consist of a steel container with an inner refractory lining, for transport, but also for carrying out metallurgical work such as alloy adjustment, desulfurization and the like. This refractory lining is subject to chemical and mechanical wear, particularly in the upper area of slag formation, so that the pan delivery has to be renewed from time to time.
Während früher die Feuerfestauskleidung hauptsächlich aus gemauerten Feuerfeststeinen bestand, ist man in jüngster Zeit mehr und mehr dazu übergegangen, die Feuerfestauskleidung aus vergossenen und verdichteten Feuerfestmassen herzustellen. Dazu wird in den Innenraum der Pfanne eine sich in der Regel nach unten verjüngende Pfannenschablone derart eingesetzt, daß zwischen der inneren Pfannenwandung und der Schablone ein Spalt entsteht, der der gewünschten Dicke der späteren Feuerfestzustellung entspricht und in dem eine Gießmasse eingefüllt wird. Diese wird durch z. B. Vibration verdichtet und anschließend getrocknet bzw. gebrannt.Whereas in the past the refractory lining consisted mainly of brick refractory bricks, more and more people have recently started to manufacture the refractory lining from poured and compacted refractory materials. For this purpose, a pan template, which generally tapers downward, is inserted into the interior of the pan in such a way that a gap is formed between the inner pan wall and the template, which corresponds to the desired thickness of the subsequent refractory delivery and into which a casting compound is poured. This is by z. B. compacted vibration and then dried or burned.
Da die Pfannen beim Unterschreiten einer bestimmten Mindestdicke der Feuerfestzustellung aus Sicherheitsgründen nicht mehr verwendet werden dürfen, jedoch nach wie vor eine nicht unerhebliche Restschichtstärke des Futters vorhanden ist, hat man die Feuerfestzustellung zweischichtig derart aufgebaut, daß unmittelbar auf der Pfannenwandung zunächst ein sogenanntes Dauerfutter angeordnet ist, dem sich das innenliegende eigentliche Verschleißfutter anschließt.Since the pans can no longer be used for safety reasons if the thickness of the refractory lining falls below a certain minimum, but there is still a not inconsiderable remaining layer thickness of the lining, the refractory lining has been built up in two layers in such a way that a so-called permanent lining is initially arranged directly on the wall of the pan , which is followed by the internal wear lining.
Dadurch muß bei der Neuzustellung der Pfanne lediglich das restliche Verschleißfutter entfernt werden.This means that only the remaining wear lining has to be removed when the pan is relined.
Das nach dem Stand der Technik verwendete Dauerfutter besteht aus Feuerfestplatten, die etwa 20 mm dick sind und zur Vermeidung von durchgehenden Fugen versetzt übereinander aufgeklebt werden.The permanent lining used according to the prior art consists of refractory plates, which are about 20 mm thick and are stuck on top of one another to avoid continuous joints.
Bei einschichtig aufgebauten Feuerfestauskleidungen ist, beispielsweise aus der europäischen Patentschrift 0 514 383, ein Verfahren bekanntgeworden, wonach die verbleibende Auskleidung durch mechanische Bearbeitung teilweise abgetragen bzw. aufgerauht wird, bevor eine Neuzustellung der Pfanne erfolgt. Diese mechanische Bearbeitung der monolitischen Zustellung ist jedoch vergleichsweise aufwendig, außerdem besteht die Gefahr, daß sich im verbleibenden Restfutter Risse bilden.In the case of refractory linings constructed in one layer, a method has become known, for example from European patent specification 0 514 383, according to which the remaining lining is partially removed or roughened by mechanical processing before the pan is relined. However, this mechanical processing of the monolithic infeed is comparatively complex, and there is also the risk that cracks will form in the remaining feed.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Feuerfestauskleidung zu schaffen, bei der ein Aufbringen des Verschleißfutters vereinfacht ist.The invention has for its object to provide a generic refractory lining, in which an application of the wear lining is simplified.
Diese Aufgabe wird dadurch gelöst, daß das Dauerfutter aus einer mit Hilfe einer Schalungsschablone gegossenen Feuerfestmasse besteht, die mit Hilfe von Ankerelementen mit der inneren Pfannenwandung verbunden ist.This object is achieved in that the permanent lining consists of a refractory mass cast using a formwork template, which is connected to the inner pan wall with the aid of anchor elements.
Bei der erfindungsgemäßen Feuerfestauskleidung ist es zunächst möglich, daß Dauerfutter mit Hilfe einer Schalungsschablone monolitisch herzustellen. Dadurch kann auf vorgefertigte Feuerfestformteile, wie sie bisher verwendet wurden, verzichtet werden. Auch entfällt das vorher erforderliche Aufkleben der einzelnen Feuerfestplatten auf die innere Pfannenwandung.In the refractory lining according to the invention, it is first possible to produce permanent feed monolithically using a formwork template. This makes it possible to dispense with prefabricated refractory molded parts, such as have been used previously. There is also no need to glue the individual refractory plates to the inner pan wall.
Das erfindungsgemäß aufgebrachte Dauerfutter ist mit Hilfe von Ankerelementen, die an der inneren Pfannenwandung angeordnet sind, fest mit dieser verbunden, so daß insgesamt die Formstabilität der Pfanne bzw. des Dauerfutters erhöht ist.The permanent lining applied according to the invention is firmly connected to this with the aid of anchor elements which are arranged on the inner pan wall, so that overall the dimensional stability of the pan or the permanent lining is increased.
Die Schichtdicke des Dauerfutters liegt vorzugsweise zwischen 60 und 150 mm, ist also gegenüber dem Stand der Technik wesentlich erhöht. Aus diesem Grunde ist die restliche abzuarbeitende Schicht des Verschleißfutters relativ dünn, so daß die Menge der zu entsorgenden Reststoffe ebenfalls vergleichsweise gering ist.The layer thickness of the permanent lining is preferably between 60 and 150 mm, so it is significantly increased compared to the prior art. For this reason, the remaining layer of the wear lining to be processed is relatively thin, so that the amount of residues to be disposed of is also comparatively small.
Ein weiterer wesentlicher Vorteil des erfindungsgemäßen Dauerfutters ergibt sich dadurch, daß das restliche Verschleißfutter beispielsweise mit Hilfe eines Meißels bis zur Fuge zwischen dem Dauerfutter und dem restlichen Verschleißfutter linienförmig von oben nach unten aufgeschlitzt werden kann, so daß sich je nach Anzahl der Schlitze zwei oder mehrere kreissegmentartige Verschleißfutterbereiche ergeben, die, beispielsweise durch Kippen der Pfanne, bequem vom Dauerfutter gelöst werden können.Another significant advantage of the permanent chuck according to the invention results from the fact that the remaining wear chuck can be slit linearly from top to bottom, for example with the aid of a chisel, up to the joint between the permanent chuck and the remaining wear chuck, so that, depending on the number of slots, two or more Circular segment-like wear lining areas that can be easily removed from the permanent lining, for example by tilting the pan.
Auf diese Weise ist eine Neuzustellung des Verschleißfutters in wesentlich kürzerer Zeit möglich als bei den bisher bekannten Feuerfestauskleidungen.In this way, a new delivery of the wear lining is possible in a significantly shorter time than with the previously known refractory linings.
Erfahrungsgemäß zeigen die Stahlpfannen in vertikaler Richtung ein unterschiedliches Verschleißverhalten derart, daß der Verschleiß im oberen Pfannenbereich wesentlich erhöht ist. Dies liegt zum einen an der höheren Badtemperatur im oberen Schmelzenbereich, zum anderen schwimmt auf der Stahlschmelze eine chemisch sehr aggressive Schlacke auf, die das Futter in diesem Bereich sehr intensiv angreift. Demzufolge ist es vorteilhaft, die Schichtdicke des Dauerfutters im unteren Pfannenbereich zu erhöhen, so daß durch diese Maßnahme die zu entfernende restliche Verschleißfutterschicht überall relativ dünn ist.Experience has shown that the steel pans show different wear behavior in the vertical direction such that the wear in the upper pan area is significantly increased. On the one hand, this is due to the higher bath temperature in the upper melt area, on the other hand, a chemically very aggressive slag floats on the steel melt, which in the feed attacks this area very intensely. Accordingly, it is advantageous to increase the layer thickness of the permanent lining in the lower pan area, so that the remaining wear lining layer to be removed is relatively thin everywhere.
Die bereits erwähnten Ankerelemente sind vorzugsweise schwalbenschwanzförmig ausgebildet und werden, beispielsweise mit dem bekannten Bolzenschweißverfahren, an der inneren Pfannenwandung verschweißt. Diese Ankerelemente sorgen für eine hervorragende Befestigung des Dauerfutters und eine Stabilitätserhöhung der Pfanne. Es ist bei der erfindungsgemäßen Feuerfestauskleidung möglich, zwischen der inneren Pfannenwandung und dem eigentlichen Dauerfutter einen Faserdämmstoff vorzusehen, der eine deutliche Verbesserung der Isolationswirkung zur Folge hat, so daß die Außentemperatur der Pfanne von üblicherweise ca. 300 °C auf etwa 200 °C sinkt. Die Faserdämmstoffmatten können in bekannter Weise auf die Innenfläche der Pfannenwandung zwischen den Ankerelementen aufgeklebt werden, wobei die Ankerelemente mit den integrierten Sockeln des gegossenen Feuerfestmaterials ein Zusammendrücken der Fasermatten verhindern.The anchor elements already mentioned are preferably dovetail-shaped and are welded to the inner pan wall, for example using the known stud welding method. These anchor elements ensure an excellent attachment of the permanent feed and an increase in the stability of the pan. It is possible with the refractory lining according to the invention to provide a fiber insulation material between the inner pan wall and the actual permanent lining, which results in a significant improvement in the insulation effect, so that the outside temperature of the pan drops from usually approximately 300 ° C. to approximately 200 ° C. The fiber insulation mats can be glued in a known manner to the inner surface of the pan wall between the anchor elements, the anchor elements with the integrated bases of the cast refractory material preventing the fiber mats from being compressed.
Dies war bei den bisherigen Feuerfestauskleidungen nicht möglich, da die Faserdämmstoffmatten durch den Druck des eigentlichen Futters zusammengepreßt und zerstört wurden.This was not possible with the previous refractory linings because the fiber insulation mats were pressed together and destroyed by the pressure of the actual lining.
Das für das Dauerfutter verwendete Feuerfestmaterial kann Stahlnadeln enthalten, die beispielsweise in einer Menge von ca. 1 % zugemischt werden. Durch diese innere Bewehrung können z. B. Wärmespannungen leichter aufgefangen bzw. abgebaut werden, so daß die Rißanfälligkeit des Futters sinkt.The refractory material used for the permanent lining can contain steel needles, which are added in an amount of approx. 1%, for example. Through this internal reinforcement z. B. thermal stresses are more easily absorbed or reduced, so that the susceptibility to cracking of the feed decreases.
Das auf das Dauerfutter aufzubringende Verschleißfutter besteht üblicherweise aus einer Spinell-bildenden Gießmasse, so daß es vorteilhaft ist, das Dauerfutter vor dem Aufbringen des Verschleißfutters zu trocknen, damit die Spinell-bildenden Massen nicht durch zusätzlichen Wasserdampf des Dauerfutters hydratisiert werden können.The wear food to be applied to the permanent food usually consists of a spinel-forming casting compound, so that it is advantageous to dry the permanent food before applying the wear food so that the spinel-forming materials are not exposed to additional steam from the permanent food can be hydrated.
Die für das Dauer- und das Verschleißfutter verwendeten Gießmassen sind vorzugsweise thixotrop eingestellt, so daß sie mit Hilfe bekannter Pump- und Verteilungssysteme problemlos in den Spalt zwischen der Pfannenwandung und der Schalungsschablone eingebracht werden können.The casting compounds used for the permanent and the wear lining are preferably thixotropic, so that they can be easily introduced into the gap between the pan wall and the formwork template with the aid of known pumping and distribution systems.
Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht und wird im nachfolgenden anhand der Zeichnung im einzelnen erläutert.The invention is illustrated in the drawing, for example, and is explained in detail below with reference to the drawing.
Die Zeichnungsfigur zeigt einen vertikalen Schnitt durch eine Stahlpfanne 1 mit einer Feuerfestzustellung 2. Die Feuerfestzustellung 2 besteht aus einem Verschleißfutter 3, das der Schmelze zugewandt ist und einem Dauerfutter 4, das sich an die innere Pfannenwandung 5 anschließt. Das Dauerfutter 4 ist an der Pfannenwandung 5 mit Hilfe von Schwalbenschwanzankern 6 befestigt.The drawing shows a vertical section through a
Beim Abgießen der Pfannenzustellung 2 werden im Bodenbereich 7 der Pfanne Kerne eingesetzt, um entsprechende Freiräume bzw. Freiflächen zum Einsetzen eines Gasspülsteins 8 bzw. eines Gießlochsteins 9 zu schaffen. Beim dargestellten Ausführungsbeispiel endet das Dauerfutter 4 kurz unterhalb der Schlackenzone 10.When pouring the pan infeed 2, cores are used in the
