Abstract
Description
Die Erfindung betrifft Kühlplatten für mit einer feuerfesten Auskleidung versehenen 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, die Kühlkanäle vertikal verlaufende Sackbohrungen sind, mit bei Bedarf zusätzlichen am Rand in der Kühlplatte angeordneten vertikalen und horizontalen Sackbohrungen kleineren Durchmessers oder mit einem auf der Kühlplatte angeordnetem Kühlsegment mit vertikal verlaufenden Sackbohrungen, die jeweils am Ende mit horizontal verlaufenden Sackbohrungen verbunden sind.The invention relates to cooling plates for shaft furnaces provided with a refractory lining, in particular blast furnaces, consisting of copper or a low-alloy copper alloy with coolant ducts arranged in their interior, the cooling plate being made from a forged or rolled ingot, the cooling ducts being vertical blind holes, with at Requires additional vertical and horizontal blind holes of smaller diameter arranged at the edge in the cooling plate or with a cooling segment arranged on the cooling plate with vertically running blind holes, which are each connected at the end to horizontally running blind holes.
Derartige Kupferkühlplatten sind üblicherweise zwischen dem Ofenmantel und der Ofenausmauerung angeordnet und an das Kühlsystem des Schachtofens angeschlossen. Auf der dem Ofeninneren zugewandten Seite sind die Kühlelemente weitgehend mit feuerfestem Material versehen.Such copper cooling plates are usually arranged between the furnace shell and the furnace lining and connected to the cooling system of the shaft furnace. On the side facing the inside of the furnace, the cooling elements are largely provided with refractory material.
Es sind Platten aus Kupferguß bekannt, bei denen die Kühlkanäle entweder durch eingegossene Stahlrohre gebildet sind oder direkt eingegossen sind. Das Gefüge von Kupferguß ist nicht so homogen und dicht wie das von geschmiedetem 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 known plates made of cast copper, in which the cooling channels are either formed by cast steel pipes or are cast directly. The structure of cast copper is not as homogeneous and dense as that of forged or rolled copper. As a result, the heat conduction of copper casting is poorer and the strength is lower. In the case of the cast-in pipes, an oxide layer between the pipe and the copper block prevents heat conduction.
Aus der DE 29 07 511 ist eine Kühlplatte bekannt, die aus einem geschmiedeten oder gewalzten Rohblock 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 gegossenen Kupferplatte; Lunker, wie sie bei Kupfergußplatten häufig auftreten, sind ausgeschlossen. Die Festigkeitswerte liegen 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, which is made from a forged or rolled ingot and where the cooling channels are vertical are blind holes that are drilled through mechanical deep drilling. The structure of the cooling plate is much denser and more homogeneous than that of a cast copper plate; Blowholes, as they often occur with cast copper plates, are excluded. The strength values are higher than that of the cast copper plates. The target position of the holes according to height and side is adhered to exactly, thereby ensuring even heat dissipation.
Die Kühlplatte ist an der dem Ofeninneren zugekehrten Seite mit Stegen und Nuten versehen und kann mit feuerfesten Steinen oder mit einer feuerfesten Stampfmasse ausgekleidet werden. Dadurch wird die Kühlfläche der Platte verkleinert und im Falle des Verschleißes bzw. des Verlustes der feuerfesten Ofenauskleidung wird der Wärmeentzug aus dem Ofen begrenzt. Die Kühlung der Platte sollte so intensiv sein, daß die Temperatur der heißen Plattenseite weit unter der Erweichungstemperatur von Kupfer gehalten wird.The cooling plate is provided with webs and grooves on the inside facing the oven and can be lined with refractory bricks or with a refractory ramming compound. This reduces the cooling surface of the plate and in the event of wear or loss of the refractory furnace lining, the heat removal from the furnace is limited. The cooling of the plate should be so intensive that the temperature of the hot plate side is kept well below the softening temperature of copper.
Aus der bisher unveröffentlichten EP 94 11 5821.4 ist eine aus einem geschmiedeten oder gewalzten Kupferrohrblock gefertigte Kühlplatte bekannt, bei der zur Kühlung der Randzonen zusätzlich zu den vertikal verlaufenden Sackbohrungen Kühlkanäle eingebracht werden, die als vertikale oder horizontale Sackbohrungen kleineren Durchmessers um die vertikal angeordneten Sackbohrungen in die Ränder eingebracht werden.From the previously unpublished EP 94 11 5821.4, a cooling plate made from a forged or rolled copper pipe block is known, in which cooling channels are introduced for cooling the edge zones in addition to the vertically running blind holes, which are vertical or horizontal blind holes of smaller diameter around the vertically arranged blind holes in the edges are introduced.
Aus der bisher unveröffentlichten DE-Patentanmeldung P 195 03 912.2 ist eine aus einem geschmiedeten oder gewalzten Kupferrohrblock gefertigte Kühlplatte bekannt, bei der zusätzlich zu den vertikal verlaufenden Sackbohrungen im oberen bzw. unteren Bereich ein zusätzliches Kühlelement, lösbar oder angeschmiedet, angebracht wird, in das zusätzlich vertikale und horizontale Sackbohrungen eingebracht werden und die über Kupferrohrstutzen ebenfalls mit dem Kühlsystem des Hochofens verbunden sind.From the previously unpublished DE patent application P 195 03 912.2, a cooling plate made from a forged or rolled copper tube block is known, in which, in addition to the vertically running blind holes in the upper or lower area, an additional cooling element, detachable or forged, is attached, into which additionally vertical and horizontal blind holes are made and are also connected to the cooling system of the blast furnace via copper pipe sockets.
Nachteilig bei der Anordnung und Befestigung dieser gewalzten Kühlplatten am Ofenpanzer ist jedoch, daß zwischen den einzelnen Kühlplatten ein vertikaler Spalt entsteht, der mit feuerfestem Material oder mit speziell zugeschnittenen Kohlenstoffsteinen ausgefüllt werden muß. Die Montage dieses Kühlsystems ist zeitaufwendig und kostenintensiv.A disadvantage of the arrangement and attachment of these rolled cooling plates on the furnace is, however, that a vertical gap is formed between the individual cooling plates, which has to be filled with refractory material or with specially cut carbon stones. The assembly of this cooling system is time consuming and costly.
Die Aufgabe der Erfindung besteht deshalb darin, ein aus Kupferkühlplatten bestehendes Kühlsystem zu schaffen, bei dem vertikal nebeneinander bzw. horizontal übereinander angeordnete Kupferkühlplatten so dicht im Inneren eines Schachtofens angebracht werden, daß die Wärmeabfuhr auch im Übergang der Kühlplatten gleichmäßig erfolgt, so daß auch dort eine Kühlung der feuerfesten Ofenauskleidung und des Ofenpanzers gewährleistet wird.The object of the invention is therefore to provide a cooling system consisting of copper cooling plates, in which copper cooling plates arranged vertically next to one another or horizontally one above the other are mounted so closely inside a shaft furnace that the heat is dissipated evenly in the transition of the cooling plates, so that there too cooling of the refractory furnace lining and the furnace shell is guaranteed.

Erfindungsgemäß werden daher an dem mit inneren Sackbohrungen versehenen Kühlkörper der geschmiedeten oder gewalzten Kupferkühlplatte entweder beidseitig verlaufende vertikale und horizontale Seitenflansche oder nur vertikale Seitenflansche ausgearbeitet, die überlappend angeordnet, ein durchgehendes Kühlsystem bilden.According to the invention, either vertical and horizontal side flanges running on both sides or only vertical side flanges, which are arranged overlapping, form a continuous cooling system on the heat sink of the forged or rolled copper cooling plate provided with inner blind bores.
Für die Bildung eines horizontalen Kühlsegmentes sind mindestens drei Kühlplatten, für die Bildung eines kompletten horizontalen Kühlringes innerhalb des Ofenpanzers sind eine Vielzahl von Kühlplatten, für die Bildung einer begrenzten Kühlfläche sind mindestens zwei Kühlplatten erforderlich.At least three cooling plates are required to form a horizontal cooling segment, a large number of cooling plates are required to form a complete horizontal cooling ring, and at least two cooling plates are required to form a limited cooling surface.
Durch die überlappende Verbindung der vertikalen Seitenflansche der Kühlelemente sind zwei verschiedene Typen von Kühlplatten erforderlich, bei denen jeweils die Stege und Nuten auf dem Kühlkörper zur Aufnahme von ff-Material dem Inneren des Hochofens zugekehrt sein müssen.Due to the overlapping connection of the vertical side flanges of the cooling elements, two different types of cooling plates are required, in each of which the webs and grooves on the cooling body for receiving ff material must face the interior of the blast furnace.
Eine der beiden Kühlplatten nach Anspruch 1 wird daher mit beidseitigen, vertikalen und horizontalen Seitenflanschen und mit horizontal angeordneten, dem Ofeninneren zugekehrten Stegen und Nuten auf dem Kühlkörper zwischen den Seitenflanschen versehen, die andere Kühlplatte wird ebenfalls mit beidseitigen, vertikalen und horizontalen Seitenflanschen und mit horizontal angeordneten, dem Ofeninneren zugekehrten Stegen und Nuten auf dem Kühlkörper und der Seitenflansche versehen.One of the two cooling plates according to
Eine der beiden Kühlplatten nach Anspruch 2 wird nur mit beidseitigen, vertikalen Seitenflanschen und mit horizontal angeordneten, dem Ofeninneren zugekehrten Stegen und Nuten auf dem Kühlkörper zwischen den Seitenflanschen versehen, die andere Kühlplatte wird ebenfalls nur mit beidseitigen, vertikalen Seitenflanschen und mit horizontal angeordneten, dem Ofeninneren zugekehrten Stegen und Nuten auf dem Kühlkörper und der Seitenflansche versehen.One of the two cooling plates according to
Sollten mehrere Lagen horizontale Kühlsegmente bzw. komplette Kühlringe übereinander im Inneren eines Hochofens angeordnet werden, so werden diese durch die horizontalen Seitenflansche der Kühlplatten überlappend gestaltet.Should there be several layers of horizontal cooling segments or complete cooling rings on top of each other inside one Blast furnace are arranged, so they are designed to overlap by the horizontal side flanges of the cooling plates.
Horizontale Kühlsegmente bzw. komplette Kühlringe können übereinander im Inneren eines Hochofens auch mit Kühlplatten ohne horizontale Seitenflansche gebildet werden. Die Kühlsegmente bzw. kompletten Kühlringe werden dann jedoch Stoß an Stoß verlegt.Horizontal cooling segments or complete cooling rings can be formed one above the other inside a blast furnace with cooling plates without horizontal side flanges. The cooling segments or complete cooling rings are then laid butt to butt.
