Abstract
Description
Die Erfindung betrifft Kühlplatten für mit einer feuerfesten Auskleidung versehene Schachtöfen, insbesondere Hochöfen, bestehend aus Kupfer oder einer niedriglegierten Kupferlegierung mit Kühlmittelkanälen, wobei die Kühlplatten aus einem geschmiedeten oder gewalzten Rohblock gefertigt sind, und auf einer Seite, der Vorderseite, angeordnete Nute zur Aufnahme von feuerfestem Material aufweisen.The invention relates to cooling plates for a refractory lining provided shaft furnaces, in particular blast furnaces made of copper or a low-alloy copper alloy with coolant channels, the cooling plates made of a forged or rolled ingot are made, and on one side, the front, arranged groove for receiving refractory material exhibit.
Derartige Kühlplatten gehören durch die DE-PS 29 07 511 zum Stand der Technik. Hier sind die Kühlkanäle in dem geschmiedeten oder gewalzten Rohblock als vertikal verlaufende Sackbohrungen vorgesehen, welche durch mechanisches Tiefbohren eingebracht werden. Derartige Kühlplatten müssen eine verhältnismäßig große Dicke aufweisen, damit die Kühlkanäle gebohrt werden können, ohne daß die Stabilität der Kühlplatten leiden. Sowohl auf der Vorder- als auch auf der Rückseite der Kühlplatten muß im Bereich der Bohrungen, genügend Kupfermaterial stehenbleiben, um den Kühlplatten die entsprechende Festigkeit zu geben. Dadurch sind sehr dicke Kupferplatten notwendig, die bei dem hohen Kupferpreis entsprechend teuer zu erstehen sind.Such cooling plates belong to the state by DE-PS 29 07 511 of the technique. Here are the cooling channels in the forged or Rolled ingot provided as vertical blind holes which are introduced by mechanical deep drilling. Such Cooling plates must have a relatively large thickness, so that the cooling channels can be drilled without the Stability of the cooling plates suffer. Both on the front as well on the back of the cooling plates in the area of the holes, enough copper material remains to cool the cooling plates to give appropriate strength. This makes very thick copper plates necessary, which is correspondingly expensive given the high copper price are available.
Dadurch daß die Kühlkanäle durch Bohrungen in die Kühlplatten eingebracht werden, können nur kreisförmige Löcher hergestellt werden. Diese kreisförmigen Sackbohrungen weisen nur verhältnismäßig kleine Oberflächen auf, an denen der entsprechende Wärmeaustausch von den Kühlplatten zum Kühlmittel erfolgen kann. Dadurch wird nur eine schlechte Wärmeableitung erreicht. Characterized in that the cooling channels through holes in the cooling plates only circular holes can be made become. These circular blind holes are only proportionate small surfaces on which the appropriate heat exchange from the cooling plates to the coolant. This will only poor heat dissipation.
Der Erfindung liegt die Aufgabe zugrunde, Kühlplatten der gattungsgemäßen Art so auszubilden, daß sie günstiger zu erstellen sind und mit denen bessere Kühlleistungen erbracht werden können.The invention has for its object cooling plates of the generic type Type in such a way that they are cheaper to produce and with which better cooling performance can be achieved.
Zur Lösung dieser Aufgabe wird vorgeschlagen, daß auf der Rückseite der Kühlplatten Kühlkanäle vorgesehen sind, die zu einem Teil durch die Kühlplatte selbst und zu einem anderen Teil durch Bleche begrenzt sind, wobei die Kühlkanäle durch Fräsen in die Rückseite der Kühlplatte und/oder die Bleche eingebracht sind.To solve this problem it is proposed that on the back of the cooling plates cooling channels are provided, which in part through the cooling plate itself and to a certain extent limited by sheets are, the cooling channels by milling in the back of the Cooling plate and / or the sheets are introduced.
Dieser Aufbau gestattet die Benutzung von erheblich dünneren Kühlplatten, da hier nur noch einmal ein geeignet dicker Steg zwischen der Vorderseite und dem Kühlkanal vorgesehen werden muß. Der zweite Teil des Kühlkanals kann durch anderes, z.B. erheblich dünneres Material, wie Stahl, gebildet werden.This construction allows the use of significantly thinner cooling plates, since there is only a suitably thick bridge between here the front and the cooling channel must be provided. The second Part of the cooling channel can be replaced by other, e.g. significantly thinner Material, such as steel.
Dadurch, daß die Kühlkanäle in die Kühlplatten gefräst werden, lassen sich beliebige Querschnittsformen und Verläufe der Kühlkanäle realisieren. Es müssen nicht, wie bei den Sackbohrungen, stets gerade Kanäle gebildet werden. Damit können die Kühlkanäle an jede beliebige Stelle der Kühlplatten gelegt werden, so daß die Kühlplatten gleichmäßiger gekühlt werden können.Because the cooling channels are milled into the cooling plates, can be any cross-sectional shape and course of the cooling channels realize. It does not always have to, as with blind holes straight channels are formed. This allows the cooling channels to be sent to everyone any place of the cooling plates are placed so that the cooling plates can be cooled more evenly.
Werden Kanäle mit großer Breite und geringer Tiefe gewählt, so werden große Flächen der Kühlplatten direkt vom Kühlmittel benetzt, so daß eine große Wärmeabfuhr möglich ist.If channels with a large width and shallow depth are selected, then so large areas of the cooling plates are wetted directly by the coolant, so that a large heat dissipation is possible.
Die Kühlkanäle auf der Kühlplatte können durch einzelne Bleche oder eine ganze Platte abgeschlossen werden. Wesentlich ist dabei, daß die Kanäle, zum Beispiel durch Verschweißen oder Verschrauben der Bleche oder Platten mit den Kühlplatten, dicht werden. Es besteht durchaus die Möglichkeit, auf der planen Rückseite der Kühlplatte als Teil der Kühlkanäle ausgebildete Bleche aufzuschweißen. Diese Bleche können zum Beispiel durch Tiefziehen oder Biegen erstellt werden, so daß die Herstellungskosten für die Kühlplatten besonders niedrig liegen. In diesem Falle lassen sich besonders dünne Kühlplatten verwenden, was wiederum eine Einsparung an teurem Kupfer ergibt.The cooling channels on the cooling plate can be through individual sheets or an entire plate can be completed. It is essential that the channels, for example by welding or screwing the Sheets or plates with the cooling plates become tight. It exists quite the possibility on the flat back of the cooling plate to weld sheet metal formed as part of the cooling channels. This Sheet metal can be created, for example, by deep drawing or bending be, so that the manufacturing costs for the cooling plates particularly lie low. In this case, particularly thin cooling plates can be used use, which in turn saves on expensive copper results.
