Description

Die Erfindung bezieht sich auf die Kühlung von Türrahmen, die in besonderem Maße .der Einwirkung von Wärme ausgesetzt sind.The invention relates to the cooling of door frames, in particular Dimensions. Are exposed to heat.

Die Kühlung besteht bekanntlich darin, daß Kühlwasser durch die Rohbäume -der Kühlra.'hmen geleitet wird, wobei sich das Wasser erwärmt. Das erwärmte Wasser gelangt nachVerlassen,der Kühlrdbmen wieder dahin, woher es gekommen ist, z. B. in einen Rückfühler.As is well known, cooling consists in that cooling water passes through the raw trees -the cooling frame is directed, whereby the water heats up. The heated water After leaving, the cooling tower goes back to where it came from, e.g. B. into a feedback sensor.

Die Erfindung besteht in einem getrennt für sich am Kühlrahmen .angeordneten hohlen Widerlagerbalken und in der zwangsläufigen Führung des Kühlwassers durch die einzelnen Hohlräume des Kühlrahmens und des Widerlagerbal.kens.The invention consists in a separately arranged on the cooling frame hollow abutment beam and in the inevitable guidance of the cooling water through the individual cavities of the cooling frame and the abutment beam.

In der Fig. i i=st eine Ausführungsform ,des Türrahmens mit einem Widerlagerbalken un=d ;zwangsläufiger Kühlung dargestellt. Der Wnderlagerbalken 2 trägt das OfengeWälbe 3. Dias durch die Einsteckrohre i dem Kühlrahmen @ zuggeführte Wasser wird in der gesamten Menge zwangsläufig auch,durch den hohlen Wi-derlagerbalken gedrückt. Er ist mit der ofenseitig angeordneten geschlossenen Eisenplatte des Kühlrahmens dicht verschweißt, bedeckt diese in der ganzen Breite. und bildet einen Hohliraum für sich.In Fig. I i = st an embodiment, the door frame with a Abutment beam un = d; compulsory cooling shown. The turnbuckle 2 carries the furnace casing 3. Slides are drawn through the insert tubes i the cooling frame @ Water is inevitably also in the entire amount, through the hollow bearing bars pressed. It is connected to the closed iron plate of the cooling frame on the oven side tightly welded, covers the entire width. and forms a cavity for themselves.

Das Kühlwasser gelangt durch die Einsteckrohre i in den unteren Teil der Hohlräume zum Schenkel 4, strömt von hier in den oberen Teil 5 des- Türrahmens und von hier durch ein in der Mitte angeordnetes Überlaufrohr 6 in -den Widerlagerbalken 2. Von hier fließt es nach links und rechts durch die an den Enden des Balkenseingeschweißten Rohre 7 schräg nach oben zum gemeinsamen Abfluß B. Die schniiÜgen Teile der Röhre 7 -liegen im Hohlraum des oberen Teiles des Kühlrahmens. ' Bekanntlich ist die Kühlwirkung des Wassers von -der Wasserführung und Wassergeschwindigkeit abhängig. je besser die Wasserführung und je höher ,die Wassergeschwindigkeit ist, um so intensiver ist die Kühlung: Der Querschnitt des Widerlagerbalkens ist im Vergleich zu .dem der Schenkel, ganz zu schweigen-von dem des Mittelstücks, klein. Er verhält sich etwa wie i : 3,5, d.h. der Querschnitt des einen Schenkels ist etwa 3,51 so groß wie der des Widerlagerbalkens. Die Wassergesch=windigkeit in dem Wi;der.lagerbalken ist dementsprechend größer. Das Kühlwasser durchfließt die getrennten Hohlräume des- Türrähmens und des Widerlagerbalkens zwangsläufig hintereinander.The cooling water reaches the lower part through the plug-in pipes i the cavities to the leg 4, flows from here into the upper part 5 of the door frame and from here through an overflow pipe 6 arranged in the middle into the abutment beam 2. From here it flows to the left and right through the welded ends of the beam Pipes 7 obliquely upwards to the common drain B. The sniffing parts of the pipe 7 - lie in the cavity of the upper part of the cooling frame. 'As is well known, the cooling effect of the water depends on the water flow and water speed. the better the water flow and the higher the water speed, the more intense is the cooling: the cross-section of the abutment beam is compared to .dem the thigh, not to mention that of the middle section, small. He behaves about like i: 3.5, i.e. the cross-section of one leg is about 3.51 as large like that of the abutment beam. The speed of the water in the winder is accordingly larger. The cooling water flows through the separate cavities of the door frame and the abutment beam inevitably one behind the other.

Dieser zwangsläufigen Wasserführung durch den Kühlrahmen zum allseitig geschlossenen Widerlagerlba.lken ist um so mehr Bedeutung beizumessen-, als der spezifische Wärmeübergang auf den Widerl:agerhalken und denTürrahmen schlechthin bei einer Ofentemperatuir von igoo bis 2000° C bedeutend höher ist als bei den höchst beanspruchten Hochleistungsdampfkesseln, deren Feuertemperaturen nur bis zu i6oo° C ansteigen.This inevitable water flow through the cooling frame to all sides The closed abutment bar is all the more important than the specific heat transfer to the abutment and the door frame at an oven temperature of igoo to 2000 ° C is significantly higher than at the highest stressed high-performance steam boilers with fire temperatures of only up to 160 ° C increase.

Die Fig. a zeigt den Einbau des Überlaufrohres 6 und die Fiihrung des Kühlwassers vom oberen Hdhlraum des Kühlrahmens 5 in die Mitte des Widerlagerbalkens 2. Die Fi;g. 3 .gibt Aufschluß über die Verteilung ,des Kühlwassers im Hohlraum des Widerlagerbalkens 2 und die Abführung des Kühlwaissers von hier durch die Röhre 7, die in ihren schräg nach oben führenden Teilen im Hohlraum de=s Kühlrahmens 5 liegen.Fig. A shows the installation of the overflow pipe 6 and the guide of the cooling water from the upper cavity of the cooling frame 5 in the middle of the abutment beam 2. The Fi; g. 3. Provides information about the distribution of the cooling water in the cavity of the abutment beam 2 and the removal of the cooling wafer from here through the tube 7, which in their obliquely upwardly leading parts in the cavity of the cooling frame 5 lie.
