Abstract
Description
Die Erfindung betrifft ein Kühlplatten system für mit einer feuerfesten Auskleidung versehenen Schachtöfen, insbesondere Hochöfen, wobei die jeweiligen Kühlplatten aus Kupfer oder einer niedriglegierten Kupferlegierung mit in ihrem Inneren angeordneten Kühlmittelkanälen bestehen aus einem geschmiedeten oder gewalzten Rohblock gefertigt sind und 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 Kühlelement mit vertikal verlaufenden Sackbohrungen, die jeweils am Ende mit horizontal verlaufenden Sackbohrungen verbunden sind.The invention relates to a cooling plate system for with a refractory lining shaft furnaces, in particular blast furnaces, the respective cooling plates made of copper or a low-alloy copper alloy with inside arranged coolant channels exist from a forged or rolled ingot are made and the cooling channels run vertically Blind holes are, with additional if necessary on the edge vertical and arranged in the cooling plate horizontal blind bores of smaller diameter or with a cooling element arranged on the cooling plate with vertical blind holes, each on End with horizontal blind holes are connected.
Derartige Kupferkühlplatten systeme sind üblicherweise zwischen dem Ofenmantel und der Ofenausmauerung angeordnet und an das Kühlsystem des Schachtofens angeschlossen. Auf der dem Ofeninneren zugewandten Seite sind die Kühlplatten weitgehend mit feuerfestem Material versehen.Such copper cooling plate systems are usually between the furnace jacket and the furnace lining and connected to the cooling system of the shaft furnace. On the side facing the inside of the stove are the Cooling plates largely with refractory material Mistake.
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.Cast copper plates are known in which the Cooling channels either through cast steel 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 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 from a forged or rolled ingot is made and where the cooling channels are vertical running blind holes, which through mechanical deep drilling are introduced. The structure the cooling plate is much denser and more homogeneous than that of a cast copper plate; Blowholes, like at Cast copper plates that occur frequently are excluded. The strength values are higher than that of cast copper plates. The target position of the holes according to height and side is adhered to exactly and thereby ensures 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 facing the inside of the oven Side with webs and grooves and can be fireproof Stones or with a refractory ramming paste to be lined. This will make the cooling surface of the Plate reduced and in case of wear or the loss of the refractory furnace lining becomes the Heat removal from the oven is limited. Cooling the Plate should be so intense that the temperature of the hot plate side far below the softening temperature is held by copper.
Aus der bisher unveröffentlichten EP 94 11 5821.4 (EP-A-0705906) 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 previously unpublished EP 94 11 5821.4 (EP-A-0705906) one from a forged or rolled copper pipe block manufactured cooling plate known for Cooling of the peripheral zones in addition to the vertical ones Blind holes cooling channels are introduced, the smaller than vertical or horizontal blind holes Diameter around the vertically arranged blind holes into the edges.
Aus der bisher unveröffentlichten DE-Patentanmeldung P 195 03 912.2 (EP-A-0731180) 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 (EP-A-0731180) is one made from a forged or Rolled copper tube block made cooling plate known in addition to the vertical running blind holes in the upper or lower Area an additional cooling element, detachable or forged, attached, in addition vertical and horizontal blind holes introduced be and the copper pipe socket also with the Cooling system of the blast furnace are connected.
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.Disadvantageous in the arrangement and attachment of these rolled cooling plates on the furnace is, however, that there is a vertical gap between the individual cooling plates arises with the refractory material or with specially cut carbon stones must become. The assembly of this cooling system is time consuming and expensive.
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 a cooling system consisting of copper cooling plates create where vertically next to each other or copper cooling plates arranged horizontally one above the other so close inside a shaft furnace be that the heat dissipation also in the transition of Cooling plates take place evenly, so that there too Cooling the refractory furnace lining and the Furnace is guaranteed.

vorteilhafte Ausgestaltungen der Erfindung sind in den
Unteransprüchen aufgeführt.The task is solved in the way it is in
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, therefore, on the inner blind holes provided heatsink of the forged or rolled copper cooling plate either side vertical and horizontal side flanges or just worked out vertical side flanges that arranged overlapping, a continuous cooling system form.
Für die Bildung eines horizontal angeordneten Kühlplattensystems 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.For the formation of a horizontally arranged cooling plate system at least three cooling plates, for the formation of one complete horizontal cooling ring within the Oven tanks are a variety of cooling plates for which Formation of a limited cooling area are at least two cooling plates required.
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 feuerfest-Material dem Inneren des Hochofens zugekehrt sein müssen.Due to the overlapping connection of the vertical Side flanges of the cooling elements are two different ones Types of cooling plates required, each of which the webs and grooves on the heat sink for receiving refractory material must face the interior of the blast furnace have to.
Eine der beiden Kühlplatten des systems 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,

Seitenflanschen versehen, die andere Kühlplatte wird
ebenfalls mit beidseitigen vertikalen Seitenflanschen
oder mit beidseitigen, horizontalen Seitenflanschen und mit horizontal angeordneten, dem Ofeninneren
zugekehrten Stegen und Nuten auf dem Kühlkörper
und der vertikalen oder horizontalen Seitenflansche versehen.One of the two cooling plates according to
Sollten mehrere Lagen horizontal augeordnete Kühlplattensysteme bzw. komplette Kühlringe übereinander im Inneren eines Hochofens angeordnet werden, so werden diese durch die horizontalen Seitenflansche der Kühlplatten überlappend gestaltet.If several layers of horizontally arranged cooling plate systems or complete cooling rings on top of each other inside one Blast furnace are arranged, so these are by the horizontal side flanges of the cooling plates overlapping designed.
Horizontal argeordnete Kühlplattensysteme bzw. komplette Kühlringe können übereinander im Inneren eines Hochofens auch mit Kühlplatten ohne horizontale Seitenflansche gebildet werden. Die Kühlplatten werden dann jedoch Stoß an Stoß verlegt.Horizontally arranged cooling plate systems or complete cooling rings can also be stacked on top of each other inside a blast furnace Cooling plates formed without horizontal side flanges become.
