Abstract
Description
Formbauteil aus Feuerfestmaterial Shaped component made of refractory material
Die Erfindung betrifft ein Formbauteil aus Feuerfestmaterial mit den Merkmalen im Oberbegriff des Schutzanspruchs 1.The invention relates to a shaped component made of refractory material having the features in the preamble of claim 1 protection.
Der Bereich des Stichlochkanals eines Schmelzofens, insbesondere eines Schachtofens wie z.B. eines Kupolofens, unterliegt starkem Verschleiß. Daher muss der Stichlochkanal von Zeit zu Zeit neu aufgebaut werden. Hierzu muss der Schmelzofen heruntergefahren und ausgeräumt werden, damit der den Stichlochkanal umgebende Bereich nicht nur von außen, sondern auch von innen neu ausgekleidet werden kann. Das neu eingebrachte Feuerfestmaterial muss anschließend trocknen, bevor der Betrieb weitergehen kann. Da in der Trockenzeit ein Betrieb des Schachtofens nicht möglich ist, entstehen erhebliche Betriebsstörungen.The area of the stitch hole channel of a melting furnace, in particular a shaft furnace such as e.g. a cupola, is subject to heavy wear. Therefore, the taphole channel must be rebuilt from time to time. For this purpose, the melting furnace has to be shut down and cleared so that the area surrounding the taphole channel can be re-lined not only from the outside, but also from the inside. The newly introduced refractory material must then dry before operation can continue. Since operation of the shaft furnace is not possible in the dry season, considerable malfunctions occur.
Der Stichlochkanal befindet sich innerhalb einer größeren Abstichöffnung des Schachtofens. Die Abstichöffnung wird in der Fachsprache auch als Kapelle bezeichnet. Aus der EP 1 630 508 A1 ist eine Anordnung zur Auskleidung einer Kapelle eines Hochofens bekannt, wobei Formbauteile aus Feuerfestmaterial verwendet werden. Es ist ein erstes vorgefertigtes Formbauteil und wenigstes ein weiteres vorgefertigtes Formbauteil vorgesehen. Die Formbauteile greifen formschlüssig ineinander und sind so konfiguriert, dass die Auskleidung der Kapelle einfach und zeitsparend erfolgen kann. Der Stichlochkanal befindet sich im mittleren Bereich eines größeren der Formbauteile. Ein wesentlicher Vorteil ist, dass durch die Verwendung vorgefertigter Formbauteile ein zeitsparender Wiederaufbau der Kapelle möglich ist als es mit dem vollständigen manuellen Ausfüllen durch Stampfmasse oder Vergießen möglich wäre.The taphole channel is located within a larger tap hole of the shaft furnace. The tapping opening is also referred to in the jargon as a chapel. From EP 1 630 508 A1, an arrangement for lining a chapel of a blast furnace is known, wherein molded components made of refractory material are used. It is a first prefabricated mold component and least another prefabricated mold component provided. The mold components engage each other in a form-fitting manner and are configured in such a way that the lining of the chapel can be made simple and time-saving. The taphole channel is located in the middle region of a larger of the mold components. A significant advantage is that the use of prefabricated molded components a time-saving reconstruction of the chapel is possible as it would be possible with the complete manual filling by ramming mass or casting.
Hieran anknüpfend, liegt der Erfindung die Aufgabe zu Grunde, ein Formbauteil aus Feuerfestmaterial zu Auskleidung einer Abstichöffnung eines Schachtofens aufzuzeigen, wobei die Standzeit des Stichlochkanals und damit der gesamten Auskleidung der Abstichöffnung erhöht ist.Based on this, the invention is based on the object to show a molded component of refractory material to lining a tap hole of a shaft furnace, the service life of the tap hole and thus the entire lining of the tap hole is increased.
Diese Aufgabe wird durch ein Formbauteil mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a mold component having the features of claim 1.
Die Neuerung besteht darin, dass der Stichlochkanal unterseitig des Formbauteils angeordnet ist, wobei die Breite des vorgefertigten Stichlochkanals vom Ofeninneren zum Ofenäußeren hin zunimmt.The innovation consists in that the tap hole channel is arranged on the underside of the molding component, wherein the width of the prefabricated tap hole channel increases from the furnace interior to the outside of the furnace.
Es hat sich gezeigt, dass der Verschleiß im Bereich des Stichlochkanals wesentlich geringer ist, wenn sich sein Querschnitt in Strömungsrichtung erweitert. Dadurch wird die Standzeit des Formbauteils wesentlich erhöht. In fertigungstechnischer Hinsicht ist es günstig, wenn der Stichlochkanal unterseitig des Formbauteils angeordnet ist. Dadurch wird der Herstellungsprozess der Formbauteile erheblich vereinfacht. Die Verwendung von Formbauteilen hat sich in der Praxis generell bewährt, da die Abstichöffnungen von Schachtöfen schnell wieder aufgebaut werden können.It has been shown that the wear in the region of the needle hole channel is substantially lower when its cross-section widens in the direction of flow. As a result, the service life of the mold component is substantially increased. In terms of manufacturing technology, it is favorable if the tap hole channel is arranged on the underside of the molded component. This considerably simplifies the manufacturing process of the molded components. The use of molded components has generally proven in practice, since the tapping openings of shaft furnaces can be quickly rebuilt.
Vorteilhafte Weiterbildungen des Erfindungsgedankens sind Gegenstand der Unteransprüche. Es wird als günstig angesehen, wenn sich die Breite des Stichlochkanals vom Ofeninneren zum Ofenäußeren hin mindestens verdoppelt. Eine Vergrößerung der Breite um mindestens den Faktor 2,5 wird besonders vorteilhaft angesehen, da sich unter diesen Voraussetzungen Strömungsverhältnisse mit relativ geringem Verschleiß des Stichlochkanals einstellen.Advantageous developments of the inventive concept are the subject of the dependent claims. It is considered favorable if the width of the taphole channel at least doubles from the inside of the oven to the outside of the oven. An increase in the width by at least a factor of 2.5 is considered particularly advantageous because set under these conditions flow conditions with relatively little wear of the taphole.
Eine besondere Bedeutung kommt allerdings nicht nur der Geometrie des Stichlochkanals zu, sondern auch der Mündung des Stichlochkanals bzw. der Mündungsseite des Formbauteils. An der ofenäußeren Seite bzw. Mündungsseite des Formbauteils treten starke Verwirbelungen auf, die zum vorzeitigen Verschleiß an der ofenäußeren Seite führen. Der Grund ist darin zu sehen, dass die Abstichrinne regelmäßig breiter ist als der eigentliche Stichlochkanal, so dass sich seitlich der aus dem Stichlochkanal austretenden Schmelze Verwirbelungen bilden, die der ofenäußeren Seite des Formbauteils zusetzen. Es ist daher vorgesehen, dass die ofenäußere Seite einen Mittelabschnitt und gegenüber dem Mittelabschnitt zurückversetzte Seitenabschnitte aufweist. Durch das Zurückversetzen der Seitenabschnitte kann in diesen Bereichen der Verschleiß des Formbauteils reduziert werden und somit die Standzeit erhöht werden. Der Übergang zwischen dem Mittelabschnitt und den Seitenabschnitten sollte nicht zu sprunghaft sein, da vorstehende Kanten besonders verschleißanfällig sind. Daher ist in vorteilhafter Weiterbildung des Erfindungsgedankens vorgesehen, dass zwischen dem Mittelabschnitt und den Seitenabschnitten Flankenabschnitte angeordnet sind, die mit der Mittellängsachse des Stichlochkanals einen Winkel in einem Bereich von 20° bis 70°, insbesondere in einem Bereich von 30° bis 60°, einschließen. Durch die Flankenabschnitte können die Wirbelströmungen in den Eckbereichen der Abstichrinne sanft umgeleitet werden, so dass der Verschleiß seitlich des Stichlochkanals reduziert werden kann.Of particular importance, however, is not only the geometry of the needle hole channel, but also the mouth of the needle hole channel or the mouth side of the molded component. On the outside of the furnace or the mouth side of the molded component, strong turbulences occur, which lead to premature wear on the outside of the furnace. The reason is that the tapping channel is regularly wider than the actual tap hole channel, so that laterally the melt emerging from the tap hole channel forms turbulences which clog the furnace outer side of the molded component. It is therefore provided that the furnace-outer side has a central portion and recessed relative to the central portion side portions. By putting the side sections back into position, the wear of the molded component can be reduced in these areas and thus the service life can be increased. The transition between the middle section and the side sections should not be too erratic, since protruding edges are particularly susceptible to wear. Therefore, it is provided in an advantageous development of the inventive idea that between the central portion and the side portions flank portions are arranged, which include an angle in the range of 20 ° to 70 °, in particular in a range of 30 ° to 60 ° with the central longitudinal axis of the needle hole channel , By means of the flank sections, the turbulences in the corner regions of the tapping channel can be gently diverted, so that the wear on the side of the taphole channel can be reduced.
Der Stichlochkanal selbst ist an seiner ofenäußeren Mündung vorzugsweise nicht breiter als der Mittelabschnitt und vorzugsweise genauso breit wie der Mittelabschnitt. Durch die aufeinander abgestimmte Breite wird der von Wirbelströmungen belastete Bereich seitlich des Mittelabschnitts bzw. seitlich des Stichlochkanals weitestgehend minimiert, wobei die Flankenabschnitte zudem vorzeitige Auswaschungen im Bereich der Breitseiten des Stichlochkanals verhindern.The taphole channel itself is preferably not wider at its outer opening than the central portion and preferably as wide as the central portion. Due to the coordinated width of the turbulent flow areas of the side of the central portion or side of the taphole channel is minimized as far as possible, the flank sections also prevent premature leaching in the area of the broad sides of the needle hole channel.
Es wird als vorteilhaft angesehen, wenn der Stichlochkanal einen rechteckigen Querschnitt aufweist, wobei seine Breite in jeder Querschnittsebene mindestens doppelt so groß ist wie seine Höhe.It is considered advantageous if the tap hole channel has a rectangular cross-section, wherein its width in each cross-sectional plane is at least twice as large as its height.
Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawings.
Die Figuren 1 und 2 zeigen in der Draufsicht und in einer perspektivischen Darstellung ein Formbauteil 1 aus Feuerfestmaterial zur Auskleidung einer nicht näher dargestellten Abstichöffnung eines Schachtofens. Das Formbauteil ist in seiner Geometrie im Wesentlichen quaderförmig ausgebildet bei einer Länge L von 1.400 mm, einer Breite B von 700 mm und einer Höhe H von ebenfalls 700 mm. Wesentlich ist die Konfiguration des Stichlochkanals 2, der in den Figuren 1 und 2 mit unterbrochener Linie eingezeichnet ist. Der Stichlochkanal 2 besitzt auf seiner dem Ofeninneren zugewandten Seite 3 eine Breite B1 von 150 mm, die in Richtung zur ofenäußeren Seite 4 auf 400 mm zunimmt. Die ofenäußere Seite 4 gliedert sich in einen Mittelabschnitt 5 sowie gegenüber dem Mittelabschnitt 5 zurückversetzte Seitenabschnitte 6. Der Mittelabschnitt 5 und die Seitenabschnitte 6 verlaufen in ihrer Orientierung parallel zueinander, wobei der Mittelabschnitt 5 gegenüber dem Seitenabschnitt 6 bei diesem Ausführungsbeispiel um etwa 200 mm vorsteht bzw. die Seitenabschnitte 6 gegenüber dem Mittelabschnitt 5 um 200 mm zurückversetzt sind.Figures 1 and 2 show in plan view and in a perspective view of a molded component 1 made of refractory material for lining a non-illustrated tapping opening of a shaft furnace. The molded component is formed in its geometry substantially parallelepiped with a length L of 1,400 mm, a width B of 700 mm and a height H of also 700 mm. Essential is the configuration of the tap hole 2, which is shown in Figures 1 and 2 with a broken line. The tap hole channel 2 has on its side facing the furnace interior side 3 a width B1 of 150 mm, which increases in the direction of the oven-side 4 to 400 mm. The middle side 5 and the side sections 6 extend parallel to one another in their orientation, the middle section 5 protruding from the side section 6 in this exemplary embodiment by approximately 200 mm or, as the case may be, in FIG ., The side portions 6 are set back relative to the central portion 5 by 200 mm.
Zwischen dem Mittelabschnitt 5 und den Seitenabschnitten 6 erstrecken sich Flankenabschnitte 7, welche mit der Mittellängsachse des Stichlochkanals 2 einen Winkel in einem Bereich von 20° bis 70°, vorzugsweise in einem Bereich von 30° bis 60°, einschließen.Between the middle section 5 and the side sections 6 extend flank sections 7, which with the central longitudinal axis of the needle hole channel 2 an angle in a range of 20 ° to 70 °, preferably in a range of 30 ° to 60 °.
Es ist zu erkennen, dass der Stichlochkanal 2 an seiner ofenäußeren Mündung 8 nicht breiter ist als der Mittelabschnitt 5, sondern quasi genauso breit wie der Mittelabschnitt 5 ist. In diesem Ausführungsbeispiel wären das 400 mm, wobei auf die Seitenabschnitte 6 und die Flankenabschnitte 7 insgesamt 300 mm entfallen. Die Flankenabschnitte 7 sind etwa genauso breit wie die Seitenabschnitte 6.It can be seen that the taphole channel 2 at its outer opening 8 is not wider than the middle section 5, but is virtually as wide as the central section 5. In this embodiment, that would be 400 mm, with the side sections 6 and the flank sections 7 total 300 mm omitted. The flank sections 7 are approximately as wide as the side sections 6.
Der Stichlochkanal 2 besitzt einen rechteckigen Querschnitt, wie in Figur 2 zu erkennen ist. Die Breite B1 des Stichlochkanals ist in jeder Querschnittsebene mindestens doppelt so groß wie seine Höhe H1.The tap hole channel 2 has a rectangular cross section, as can be seen in Figure 2. The width B1 of the taphole channel is at least twice as large as its height H1 in each cross-sectional plane.
In den Figuren 1 und 2 ist ferner eine Nut zu erkennen, die sich mit Ausnahme der den Stichlochkanal 2 aufnehmenden Unterseite des Formbauteils 1 über alle drei Seiten des Formbauteils im Bereich des Außenumfangs erstreckt. Die Nut dient zur Einbringung von Feuerfestmasse, um das Formbauteil 1 innerhalb der Kapelle bzw. der Abstichöffnung des Schachtofens zu vergießen und so das Formbauteil zu verankern. Grundsätzlich werden die zwischen dem Formbauteil 1 und der nicht näher dargestellten Wandung der Abstichöffnung verbleibenden Freiräume mit Feuerfestmasse ausgegossen. Das gilt sowohl für den Bereich der Nut 9 als auch für die übrigen Längsseiten. Die auszugießenden Freiräume können je nach Formgenauigkeit des Formbauteils 1 relativ schmal sein.FIGS. 1 and 2 also show a groove which, with the exception of the underside of the molded component 1 receiving the taphole channel 2, extends over all three sides of the molded component in the region of the outer circumference. The groove serves to introduce refractory material in order to cast the molded component 1 within the chapel or the tapping opening of the shaft furnace and thus to anchor the molded component. Basically, the remaining between the mold part 1 and the wall of the tap not shown free spaces are poured with refractory material. This applies both to the area of the groove 9 and to the other long sides. Depending on the dimensional accuracy of the molded component 1, the free spaces to be poured out can be relatively narrow.
Gegenüber bekannten Formbauteilen zeichnet sich das erfindungsgemäße Formbauteil 1 auch dadurch aus, dass es im Verhältnis zur Höhe und Breite eine deutlich größere Länge aufweist, was erheblich zur Standzeitverbesserung beiträgt. Während herkömmliche Formbauteile eine Länge von beispielsweise 500 mm aufweisen, ist die Länge L des Formbauteils wenigstens doppelt so groß, d.h. sie beträgt mindestens 1.000 mm. Bezogen auf die Höhe und Breite des Formbauteils 1 lässt sich sagen, dass die Länge L mindestens doppelt so groß ist wie die Höhe H oder Breite B des Formbauteils 1. Compared to known mold components, the molded component 1 according to the invention is also distinguished by the fact that it has a significantly greater length in relation to the height and width, which contributes significantly to the improvement in service life. While conventional molded components have a length of, for example, 500 mm, the length L of the molded component is at least twice as large, ie it is at least 1,000 mm. With regard to the height and width of the molded component 1, it can be said that the length L is at least twice as large as the height H or width B of the molded component 1.
