Definitions
- 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.
- Such cooling plates belong to the state by DE-PS 29 07 511 of the technique.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Figure 1 showed a cooling plate 1, the 2 on its front Has groove 3, which is intended for receiving refractory material are.
- coolant channels 5 milled. These channels are not very deep in that Back 4 milled, but have a relatively large Width.
- the channels 5 are closed by sheets 6.
- the sheets 6 are welded onto the cooling plate 1.
- the sheets 6 serve at the same time to receive the supply / discharge lines 7 for the coolant.
- the supply / discharge lines 7 are welded into the bores 8 of the sheets 6.
- FIG. 2 shows the inner wall 9 of a blast furnace to which a cooling plate 1 is screwed on.
- the coolant channels 5 Back 4 of the cooling plate 1 is not by a variety of Sheets 6, but overlaid by a single plate 6 '.
