Abstract

The invention relates to a stave for shaft kilns, especially blast furnaces, with a refractory lining. The stave comprises cooling channels which can be impinged upon with a coolant. At least the front facing the interior of the kiln consists of a rolled component that is provided with grooves for receiving refractory material and is preferably made of copper or a low-alloy copper alloy. The aim of the invention is to improve said stave in such a way that it can be easily produced and assembled using little material. The aim of the invention is also to provide a stave that provides higher cooling performance with lower coolant throughput, whereby the temperature rise of the stave is limited in such a way that the times of exposure are significantly longer. To this end, two trough-shaped rolled sections are welded together with the troughs thereof facing the exterior. Bores for receiving the ends of pipe connection pieces are inserted into the rear supplementary section. Said bores are welded-in. The free ends of the rolled steel sections are closed by means of caps.

Description

Kühlplatte für KühlschachtöfenCooling plate for cooling shaft furnaces
Die Erfindung betrifft Kühlplatten (sog. "Staves") für mit einer feuerfesten Auskleidung versehene Schachtöfen, insbesondere Hochöfen, mit von einem Kühlmittel beaufschlagbaren Kühlkanälen, wobei mindestens die zum Ofeninneren gewandte Frontseite aus einem mit Nuten zur Aufnahme von feuerfesten Material ausgestatteten, vorzugsweise aus Kupfer oder einer niedrig legierten Kupferlegierung gefertigten Walzblock besteht.The invention relates to cooling plates (so-called “staves”) for shaft furnaces provided with a refractory lining, in particular blast furnaces, with cooling passages which can be acted upon by a coolant, at least the front side facing the furnace interior having a groove, preferably made of copper, for receiving refractory material or a low-alloyed copper alloy billet.
Es ist bekannt, derartige Kühlplatten mit einer Wasserkühlung zu versehen und sie aus Kupfer oder einer nur gering legierten Kupferlegierung herzustellen, um der abzuführenden Wärme einen geringen Widerstand zu bieten.It is known to provide cooling plates of this type with water cooling and to produce them from copper or a low-alloy copper alloy in order to offer little resistance to the heat to be removed.
In der vorbekannten DE-PS 29 07 511 sind die Kühlkanäle in einem geschmiedeten oder gewalzten Rohblock als vertikal verlaufende Sackbohrungen vorgesehen, welche durch mechanische Tiefbohrungen eingebracht sind. Derartige Kühlplatten müssen eine verhältnismäßig große Dicke aufweisen, damit die Kühlkanäle noch genügend Wandstärke aufweisen, um den Betriebsdruck des Kühlmittels aufnehmen zu können. Kupferplatten der hierdurch erforderlichen Dicke sind des hohen Kupferpreises wegen kostspielig. Die Sackbohrungen weisen bei kreisförmigem Querschnitt nur die geringstmögliche innere Oberfläche auf. Dadurch steht zum Wärmeaustausch mit dem Kühlmittel nur wenig Fläche zur Verfügung, es wird nur eine mäßige Wärmeableitung erreicht. Dies bedingt hohe thermische Beanspruchungen der Kühlplatte und beeinflußt deren Standzeit unvorteilhaft.In the previously known DE-PS 29 07 511, the cooling channels in a forged or rolled ingot are provided as vertically running blind bores which are introduced through mechanical deep bores. Such cooling plates must have a relatively large thickness so that the cooling channels still have sufficient wall thickness to be able to absorb the operating pressure of the coolant. Copper plates of the required thickness are expensive because of the high copper price. With a circular cross-section, the blind holes only have the smallest possible inner surface. As a result, there is only a small area available for heat exchange with the coolant, and only moderate heat dissipation is achieved. This causes high thermal stresses on the cooling plate and adversely affects its service life.
Der Erfindung liegt daher die Aufgabe zugrunde, Kühlplatten der gattungsgemäßen Art so auszubilden, daß sie mit geringerem Material- und Fertigungsaufwand herzustellen und einfacher zu montieren sind als die bisher bekannten, und daß mit ihnen höhere Kühlleistungen bei geringerem Kühlmittel-Durchsatz erbracht werden können, wobei die Eigenerwärmung derartig begrenzt ist, daß sich wesentlich längere Standzeiten erreichen lassen.The invention is therefore based on the object of designing cooling plates of the generic type in such a way that they can be produced with less material and production outlay and are easier to assemble than the previously known, and that they can be used to achieve higher cooling capacities with a lower coolant throughput, the self-heating being so limited that considerably longer service lives can be achieved.
Zur Lösung dieser Aufgabe wird vorgesehen, das Frontteil der Kühlplatte im Mittelbereich muldenförmig als gewölbtes Walzteil relativ geringer Stärke herzustellen, so daß eine erhebliche Kupfereinsparung eintritt, und die Wölbung durch ein zweites, ebenfalls nach außen gewölbtes Walzteil zu einem Kühlkanal mit von der Kreisform abweichendem Querschnitt und somit höherer Kühlleistung zu ergänzen. Zum Vorteil des geringen Kupferverbrauches gesellt sich damit der Vorzug intensiver Kühlung, welche die Standzeit wunschgemäß verlängert.To solve this problem, it is provided that the front part of the cooling plate is trough-shaped in the middle region as a curved rolling part of relatively low thickness, so that considerable copper savings occur, and the curvature by means of a second rolling part, which is also curved outwards, to form a cooling channel with a cross section deviating from the circular shape and thus to add higher cooling capacity. The advantage of low copper consumption is the advantage of intensive cooling, which extends the service life as desired.
Vorteilhafte und zweckmäßige Weiterbildungen des Gegenstandes der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous and expedient developments of the subject matter of the invention are characterized in the subclaims.
Erläutert wird die Erfindung anhand der Beschreibung eines Ausführungsbeispieles in Verbindung mit dieses darstellenden Zeichnungen. Es zeigen hierbei:The invention is explained on the basis of the description of an exemplary embodiment in conjunction with the drawings which illustrate the same. They show:
Figur 1 einen mittigen Querschnitt durch die Kühlplatte;1 shows a central cross section through the cooling plate;
Figur 2 einen im Bereich eines der Rohranschlußstücke geführten2 shows a guided in the area of one of the pipe fittings
Querschnitt durch die Kühlplatte,Cross section through the cooling plate,
Figur 3 einen zweifach unterbrochenen Längsschnitt durch eine in einerFigure 3 shows a double interrupted longitudinal section through one in a
Schachtofenwandung montierten Kühlplatte und,Shaft plate mounted cooling plate and,
Figur 4 die Rückansicht der Kühlplatte.Figure 4 is the rear view of the cooling plate.
In Figur 1 ist ein in die Mitte der Länge gelegter Querschnitt einer Kühlplatte dargestellt, die einen zum Ofeninneren gewendeten Schild 1 zeigt, der aus Kupfer oder einer Kupferlegierung muldenförmig gewalzt ist. Bei diesem Schild 1 sind in die freie Oberfläche quer verlaufende Nute 4 mit eingewalzt, die beim Abschluß der Montage das Auftragen feuerfester Stampf- oder Spritzmassen erleichtern, und die später das Anhaften von Möllerbestandteilen begünstigen. Um einen leistungsfähigen Kühlkanal 2 zu schaffen, ist ein Ergänzungsprofil 3 durch Schweißnähte 13 mit dem Schild 1 verbunden. Dieses Ergänzungsprofil ist ebenfalls muldenartig gewalzt; es enthält jedoch über wesentliche Teile seiner Länge noch einen von dessen Mitte aus sich senkrecht erstreckenden Steg 5, der einerseits die Stabilität der gesamten Kühlplatte erhöht, und der andererseits deren Montage erleichtert.FIG. 1 shows a cross section of a cooling plate, which is placed in the middle of the length and shows a shield 1 turned towards the inside of the furnace, which is rolled out of copper or a copper alloy in a trough shape. With this sign 1 are rolled into the free surface transverse groove 4, which facilitate the application of refractory ramming or spraying compounds at the end of the assembly, and which later favor the adhesion of Möller components. In order to create an efficient cooling duct 2, a supplementary profile 3 is connected to the shield 1 by weld seams 13. This supplementary profile is also trough-shaped; However, over substantial parts of its length, it also contains a web 5 which extends vertically from the center thereof and which on the one hand increases the stability of the entire cooling plate and on the other hand facilitates its assembly.
Zur Montage wird an der Innenwand 9 des Schachtofens eine Halterung 8 befestigt, im Ausführungsbeispiel verschweißt, die mit Bohrungen 6 versehen ist. Zur Montage genügt es dann, den Steg 5 in die Halterung 8 einzuführen und von der Seite her eine mit der Bohrung 6 in der Halterung 8 fluchtende Bohrung 6' in den Steg 5 einzubringen. Die eigentliche Verbindung wird durch Einschieben und Sichern des Bolzens 7 in die Bohrungen 6, 6' hergestellt. Anschließend kann die Kühlplatte mit der Hinterfüllmasse 10 vergossen werden und dann, in der Figur 1 nicht dargestellt, die Oberfläche des Schildes 1 der Kühlplatte mit einer feuerfesten Stampf- oder Spritzmasse abgedeckt werden.For mounting, a bracket 8 is attached to the inner wall 9 of the shaft furnace, welded in the exemplary embodiment, which is provided with holes 6. For assembly, it is then sufficient to insert the web 5 into the holder 8 and, from the side, to insert a bore 6 ′ aligned with the bore 6 in the holder 8 into the web 5. The actual connection is made by inserting and securing the bolt 7 into the bores 6, 6 '. The cooling plate can then be cast with the backfilling compound 10 and then, not shown in FIG. 1, the surface of the shield 1 of the cooling plate can be covered with a refractory ramming or spray compound.
Die Figur 2 zeigt ebenfalls einen Querschnitt durch die Kühlplatte, jedoch in deren Endbereich. Hier sind wieder der Schild 1 sowie das Ergänzungsprofil 3 gezeigt, die durch Schweißnähte 13 miteinander fest und dicht verbunden sind. In eine im Ergänzungsprofil 3 vorgesehene Bohrung ist das eine Ende eines Rohranschlußstückes 12 eingeschoben und mit dem Ergänzungsprofil fest und dicht durch eine Schweißnaht 14 verbunden. Ein entsprechender Längsschnitt, der insbesondere beide Enden mit Kappen 11 und Rohranschlußstücken 12 zeigt, ist in Figur 3 dargestellt.Figure 2 also shows a cross section through the cooling plate, but in its end region. Here again the shield 1 and the supplementary profile 3 are shown, which are firmly and tightly connected to one another by weld seams 13. One end of a pipe connection piece 12 is inserted into a bore provided in the supplementary profile 3 and firmly and tightly connected to the supplementary profile by a weld seam 14. A corresponding longitudinal section, which shows in particular both ends with caps 11 and pipe fittings 12, is shown in FIG.
Die Kühlplatte wird in der Praxis nicht einzeln verwendet, sie ist als Modul gedacht, das zu größeren Kühlflächen zusammenstellbar ist. Die Montage der Kühl-elemente erfolgt hierbei in einer Weise, daß die seitlich des Kühlkanals liegenden Vorderteile der Kühlplatte, die hierbei nur ein Element der Kühlfläche darstellt, sich mit den entsprechenden Teilen der benachbarten Kühiplatte überlappen. Auf diese Weise kann auch in konischen Teilen eines Hochofenpanzers, beispielsweise Rast, Schacht oder dergleichen, ein Ausgleich der unterschiedlichen Durchmesser bzw. Umfange des Panzers erfolgen, ohne daß die Breiten-Abmessungen der Kühlplatte entsprechend der Konusform angepaßt werden müssen.In practice, the cooling plate is not used individually, it is intended as a module that can be combined into larger cooling surfaces. The cooling elements are installed in such a way that the side of the cooling channel lying front parts of the cooling plate, which here is only one element of the cooling surface, overlap with the corresponding parts of the adjacent cooling plate. In this way, the different diameters or circumferences of the shell can also be compensated for in conical parts of a blast furnace shell, for example a rest, shaft or the like, without the width dimensions of the cooling plate having to be adapted to the cone shape.
Die Verschweißung des Schildes 1 mit dem Ergänzungsprofil 3 zur Kühlplatte bzw. zum modularen Kühlelement erfolgt vorzugsweise kontinuierlich auf einem entsprechenden Schweißautomaten, so daß eine gleichmäßige, fehlerfreie und flüssigkeitsdichte Ausbildung der Schweißnaht gewährleistet ist. Während aus Wärmeleitgründen der Schild 1 aus Kupfer oder einer kupferreichen Legierung gefertigt ist, können für das Ergänzungsprofil 3 auch billigere Werkstoffe herangezogen werden, die gegebenenfalls den Vorteil höherer Festigkeit aufweisen. Wesentlich ist nur, daß Schild 1 und Ergänzungsprofil 3 sich gut und leicht verschweißen lassen. The welding of the shield 1 with the supplementary profile 3 to the cooling plate or to the modular cooling element is preferably carried out continuously on an appropriate welding machine, so that a uniform, error-free and liquid-tight design of the weld seam is ensured. While the shield 1 is made of copper or a copper-rich alloy for thermal conductivity reasons, cheaper materials can also be used for the supplementary profile 3, which may have the advantage of higher strength. It is only important that the shield 1 and supplementary profile 3 can be welded well and easily.
