Description
Die Erfindung bezieht sich auf Kühlrahmen für Siemens-Martin-Öfen oder andere Industrieöfen.The invention relates to cooling frames for Siemens-Martin ovens or other industrial furnaces.
In der Zeichnung ist -in Fig. r bis 3 ein Kühlrahmen dargestellt, wie er bisher zum Kühlen hochbeanspruchter Mauenver'kteile von Siemens-Martin-Ofen. verwendet wurde. Das Kühlwasser wird dem Rahmen durch zwei Einsteckröhre a von oben zugeführt. Ein Teil fließt in .die mit Spritzdüsen versehene Verbindungsleitung b der beiden Einsteckrohre a. Der Rest des Kühlwassers gelangt am unteren Ende der Einstedkrohre a in die beiden Schenkel c des Kühlrahmens.In the drawing, a cooling frame is shown in Fig. R to 3, like it used to be for cooling highly stressed wall-mounted parts from Siemens-Martin ovens. was used. The cooling water is supplied to the frame through two plug-in tubes a from above fed. Part of it flows into the connecting line equipped with spray nozzles b of the two insert tubes a. The rest of the cooling water arrives at the lower end of the Einedkrohre a in the two legs c of the cooling frame.
Diese bekannten Kühlrahmen weisen bei Anwendung der Heißkühlung den Mangel auf, daß in Höhe der Verbindungsleitung b an der inneren Wandung örtlich ein starker Verschleiß auftritt, der die Rahmen vorzeitig unbrauchbar macht. Dies ist darauf zurückzuführen, -daß das mit Verdampfungstemperatur eingeführte Kühlwasser von den Spritzdüsen der Veribindungsleitung b punktweise auf die heiße Wandung auftrifft und dort Dampfpolster bildet, durch die an den betreffenden Stellen die Wandung korrodiert.These known cooling frames have the use of hot cooling Lack of that locally at the level of the connecting line b on the inner wall heavy wear occurs, which makes the frame unusable prematurely. this is due to the fact that the cooling water introduced at evaporation temperature from the spray nozzles of the connecting line b hits the hot wall point by point and there forms steam cushions through which the wall at the relevant points corroded.
Die Erfindung folgt demgegenüber dem Leitgesunken, den hervorstehenden Teil i des Kühlrahmens g, der der hohen Temperatur des Siemens-Martin-Ofens am stärksten ausgesetzt isst, auf der ganzen Breite des Kühlrahmens im. wesentlichen gleichmäßig zu kühlen, so saß der örtliche Verschleiß vermieden wird. Eine Vermehrung der Spritzdüsen vermag dies nicht zu bewirken. Statt dessen sieht die Erfindung vor, da,ß das Kühlwasser von der Verbindungsleitung b über zwei Stutzen d in ein Rohr e geleitet wird, das auf der ganzen Länge mit einem Schlitz lt versehen ist (Fig. q. und 5). Das Wasser trifft aus dem Schlitz hin der ganzen Breite des Kühlrahmens gleichmäßig gegen dessen heißesfien Wandteil. An dem geschlitzten Rohr e sind oben .und unten Leitbleche angeordnet, die das Wasser in beide Richtungen führen und damit auch eine gleichmäßige Kühlung der angrenzenden Wandteile sicherstellen.In contrast, the invention follows the guide sunk, the protruding part i of the cooling frame g, which is most exposed to the high temperature of the Siemens-Martin oven, over the entire width of the cooling frame. to cool substantially evenly, so local wear and tear is avoided. An increase in the number of spray nozzles cannot do this. Instead, the invention provides that ß the cooling water is passed from the connecting line b via two nozzles d into a pipe e, which is provided with a slot along its entire length (Fig. Q. And 5). The water hits the entire width of the cooling frame from the slot evenly against its hot wall part. At the top and bottom of the slotted tube e there are baffles that guide the water in both directions and thus also ensure uniform cooling of the adjacent wall parts.
Eine abgeänderte Ausführungsform ist in Fig. 6 dargestellt. Bei dieser Anordnung gelangt das Kühlwasser auf dem gleichen Wege in ein Rohr k, das zugleich die äußere Begrenzung des vorragenden Kühlrahmenteiles bildet. Das Wasser tritt durch mindestens einen Längsschlitz i in das Innere des Kühlrahmens aus.A modified embodiment is shown in FIG. At this Arrangement, the cooling water arrives in the same way in a pipe k, which at the same time forms the outer boundary of the protruding cooling frame part. The water kicks in through at least one longitudinal slot i into the interior of the cooling frame.
