Abstract

Cooling plate for a shaft furnace, esp. a blast furnace, equipped with a fireproof lining, consists of copper or a low-alloyed copper alloy and has cooling channels within it. The cooling plate is made from a cast or rolled ingot and the cooling channels are vertical blind bores. The plate is novel in that additional vertical and horizontal blind bores (13,14) of smaller dia than the main bores (3) are provided in the edge regions of the plate.

Description

Die Erfindung betrifft eine Kühlplatte für mit einer feuerfesten Auskleidung versehene Schachtöfen, insbesondere Hochöfen, bestehend aus Kupfer oder einer niedriglegierten Kupferlegierung mit in ihrem Inneren angeordneten Kühlmittelkanälen, wobei die Kühlplatte aus einem geschmiedeten oder gewalzten Rohblock gefertigt ist und die Kühlkanäle als vertikal verlaufende Sackbohrungen angeordnet sind.The invention relates to a cooling plate for with a refractory lining shaft furnaces, in particular Blast furnaces consisting of copper or one low-alloy copper alloy with inside arranged coolant channels, the cooling plate made from a forged or rolled ingot and the cooling channels as vertical Blind holes are arranged.

Derartige Kühlplatten sind üblicherweise zwischen dem Ofenmantel und der Ofenausmauerung angeordnet und an das Kühlsystem des Schachtofens angeschlossen. Auf der dem Ofeninnern zugewandten Seite sind die Kühlelemente zum Teil mit feuerfestem Material versehen.Such cooling plates are usually between the Furnace jacket and the furnace lining arranged and on the cooling system of the shaft furnace is connected. On the the cooling elements are on the inside of the furnace partly provided with fireproof material.

Es sind Kühlplatten bekannt, bei denen die Kühlkanäle durch in Gußeisen eingegossene Rohre gebildet werden. Diese Platten haben eine geringe Wärmeabfuhr infolge der geringen Wärmeleitfähigkeit des Gußeisens und wegen des Widerstandes zwischen den Kühlrohren und dem Plattenkörper, verursacht durch eine Oxidschicht oder einen Luftspalt.Cooling plates are known in which the cooling channels are formed by pipes cast in cast iron. These plates have little heat dissipation as a result the low thermal conductivity of cast iron and because of the resistance between the cooling pipes and the Plate body caused by an oxide layer or an air gap.

Im Falle eines Verlustes des Hochofenmauerwerks nach einer gewissen Betriebszeit ist die Innenfläche der Kühlplatten direkt der Ofentemperatur ausgesetzt. Da die Ofentemperatur weit oberhalb der Schmelztemperatur des Gußeisens liegt und die inneren Wärmedurchgangswiderstände der Kühlplatten zu einer ungenügenden Kühlung der heißen Plattenseite führen, ist ein beschleunigter Verschleiß der gußeisernen Platten unvermeidbar und die Standzeit entsprechend begrenzt. In case of loss of the blast furnace masonry a certain operating time is the inner surface of the Cooling plates exposed directly to the oven temperature. There the furnace temperature is well above the melting temperature of the cast iron and the internal thermal resistance of the cooling plates to an insufficient Cooling the hot plate side is an accelerated Wear of the cast iron plates inevitable and the service life is limited accordingly.

Es sind weiterhin Platten aus Kupferguß bekannt, bei denen die Kühlkanäle entweder durch eingegossene Rohre gebildet sind oder direkt eingegossen sind. Das Gefüge von Kupferguß ist nicht so homogen und dicht wie das von geschmiedeten bzw. gewalztem Kupfer. Infolgedessen ist auch die Wärmeleitung von Kupferguß schlechter und die Festigkeit geringer. Bei den eingegossenen Rohren behindert eine Oxidschicht zwischen Rohr und Kupferblock die Wärmeleitung.There are also known plates made of cast copper, at which the cooling channels either through cast pipes are formed or cast directly. The structure of copper casting is not as homogeneous and dense as that of forged or rolled copper. Consequently the heat conduction of copper casting is also worse and the strength less. For the cast pipes prevents an oxide layer between the pipe and the copper block the heat conduction.

Aus der DE 29 07 511 ist eine Kühlplatte bekannt, die aus einem geschmiedeten oder gewalzten Rohrblock gefertigt ist und wo die Kühlkanäle vertikal verlaufende Sackbohrungen sind, welche durch mechanisches Tiefbohren eingebracht sind. Das Gefüge der Kühlplatte ist wesentlich dichter und homogener als das einer Kupfergußplatte; Lunker, wie sie bei Kupfergußplatten häufig auftreten, sind ausgeschlossen. Die Festigkeitswerte liegen höher und die Wärmeleitfähigkeit ist gleichmäßiger und höher als die der gegossenen Kupferplatten. Die Sollage der Bohrungen nach Höhe und Seite wird genau eingehalten und dadurch eine gleichmäßige Wärmeabfuhr gewährleistet.From DE 29 07 511 a cooling plate is known made from a forged or rolled tube block is and where the cooling channels run vertically Blind holes are through mechanical deep drilling are introduced. The structure of the cooling plate is much denser and more homogeneous than that of a cast copper plate; Blowholes, as they are common with cast copper plates occur are excluded. The strength values are higher and the thermal conductivity is more even and higher than that of the cast copper plates. The target position of the holes according to height and side is adhered to exactly and therefore even heat dissipation guaranteed.

Die Kühlplatte ist an der dem Ofeninnern zugekehrten Seite mit feuerfesten Steinen oder mit einer feuerfesten Stampfmasse ausgekleidet. Dadurch wird die Heizfläche der Platte verkleinert und im Falle des Verschleißes bzw. des Verlustes der feuerfesten Ofenauskleidung wird der Wärmeentzug aus dem Ofen begrenzt. Ferner sollte die Kühlung der Platte so intensiv sein, daß die Temperatur der heißen Plattenseite weit unter der Erweichungstemperatur von Kupfer gehalten wird. The cooling plate faces the inside of the furnace Side with refractory bricks or with a refractory Rammed earth lined. This will make the heating surface the plate downsized and in case of wear or the loss of the refractory furnace lining heat removal from the oven is limited. Furthermore, the cooling of the plate should be so intense that the temperature of the hot plate side is well below the softening temperature of copper is maintained.

Nachteilig bei diesen gewalzten oder geschmiedeten Kupferkühlplatten ist jedoch, daß die Kühlung an den Randzonen nicht optimal ist und dadurch eine Kühlung der Fugen der feuerfesten Stampfmassen bzw. ff-Steine zwischen den Kühlplatten nicht ausreichend ist.A disadvantage of these rolled or forged Copper cooling plates, however, is that cooling to the Marginal zones is not optimal and therefore cooling the joints of the refractory ramming compounds or ff-stones between the cooling plates is not sufficient.

Die Aufgabe der Erfindung besteht deshalb darin, eine Kühlplatte zu schaffen, bei der die Randzonen in das Kühlsystem einbezogen werden und die Wärmeabfuhr in den Platten gleichmäßiger und homogener erfolgt, so daß eine verbesserte Kühlung der feuerfesten Ofenauskleidung und des Ofenpanzers gewährleistet wird und dadurch höhere Standzeiten erreicht werden. Ferner soll die Aufhängung der Kühlplatte am Ofenpanzerblech verbessert werden, um Wärmespannungen in der Kühlplatte besser abbauen zu können.The object of the invention is therefore a To create a cooling plate in which the edge zones in the Cooling system to be included and heat dissipation in the Plates are made more evenly and homogeneously, so that improved cooling of the refractory furnace lining and the furnace is guaranteed and thereby longer service lives can be achieved. Furthermore, the Suspension of the cooling plate on the furnace shell improved to better reduce thermal stresses in the cooling plate to be able to.

Erfindungsgemäß werden daher in die geschmiedete oder gewalzte Kupferkühlplatte zusätzliche Kühlkanäle eingebracht, die als vertikale oder horizontale Sackbohrungen kleineren Durchmessers um die vertikal angeordneten Sackbohrungen in die Ränder der Kühlplatte eingebracht werden. Diese vertikalen und horizontalen Sackbohrungen werden endseitig durch verschweißte oder verlötete Stopfen dicht verschlossen.According to the invention are therefore in the forged or rolled copper cooling plate introduced additional cooling channels, the as vertical or horizontal Blind holes of smaller diameter around the vertical arranged blind holes in the edges of the cooling plate be introduced. These vertical and horizontal Blind holes are welded at the ends or soldered plugs tightly closed.

Durch die dem Ofeninneren abgewandeten Seite der Kühlplatte werden jeweils im Bereich des Transporthakens in die horizontalen Sackbohrungen kleineren Durchmessers horizontal verlaufende Rohrstücke mit gegenüber den vertikalen und horizontalen Sackbohrungen vergrößertem Querschnitt angebracht, an denen jeweils ein gemeinsamer Kühlmittelzu- oder abfluß angeordnet ist.Through the side of the cooling plate facing away from the inside of the oven are in each case in the area of the transport hook the horizontal blind holes of smaller diameter horizontal pipe sections with opposite the vertical and horizontal blind holes enlarged Cross section attached to each one common coolant inflow or outflow is arranged.

An der dem Ofeninneren abgewandeten Seite der Kühlplatte wird ferner mindestens eine zentrisch angeordnete Aussparung vorgesehen, in die ein am Hochofenpanzer befestigter Tragzapfen eingreift.On the side of the cooling plate facing away from the inside of the oven is also at least one centrally arranged Recess provided in the one on the blast furnace attached trunnion engages.
