  • the invention relates to a cooling plate with the features of the preamble of Claim 1.
  • the Oven shell by cooling plates, which are arranged inside the furnace shell.
  • staves can be made from pipes cast in cast iron cast pipes in copper or a copper alloy, or deep-drilled or milled copper plates.
  • the pipes or coolant channels serve the Management of a cooling medium. Water is preferably used.
  • the Cooling plates have on their back facing the furnace usually pipe exits that are led outside through the furnace shell. These coolant pipes lead the coolant outside of the furnace additional cooling plate or manifolds.
  • the cooling plates are usually attached using screw bolts attached to the Furnace armor can be screwed or welded. It is also known that Cooling plates over the cooling tubes and compensators connected to the cooling tubes to be attached to the furnace shell (WO 01/20045 A1). With screwed Connections are additionally made to the screws covering caps on the Welded outside of the furnace shell to ensure the necessary gas tightness of the To ensure the oven.
  • the cooling plates are exposed to strong thermal loads during use, whereby it can happen in individual cases that the usually prevailing loads be exceeded significantly. These extraordinary thermal Loads result especially when using cooling plates made of copper or low-alloy copper alloys to warp the cooling plates. This delay Experience has shown that it has the greatest impact on the outer edges of the cooling plates.
  • the object of the invention is to provide a cooling plate for to show metallurgical furnaces in which thermally induced distortion of the Cooling plate does not increase the voltages in the connected Coolant pipes leads.
  • This object is in a cooling plate with the features of claim 1 solved in that the compensator is not facing away from the cooling plate Arranged outside of the furnace shell and connected there to the coolant pipe is, but at least in sections between that of the furnace facing back of the cooling plate and the cooling plate facing Extends inside of the furnace shell, the coolant pipes with radial Distance through the compensators and not directly with the Compensator are connected. Rather, the compensator surrounds the coolant pipe in the space between the cooling plate and the furnace shell.
  • the Compensators and the coolant pipes are independent of each other on the Cooling plate attached. This has the advantage that the cooling plate in one Compensator forces not applied to an inside the compensator arranged coolant pipe can be transmitted. Hence none can undesirable voltage peaks in the transition area between the cooling plate and Coolant pipe or arise in the coolant pipe itself.
  • the compensator can be used directly or via an intermediate adapter be connected to the back of the cooling plate.
  • the connection is made preferably by welding.
  • the compensator can also be detached be connected to the back of the cooling plate.
  • a screwdriving Connection to the cooling plate is conceivable.
  • the second end of the compensator facing away from the cooling plate is connected to the Furnace connected. It is preferably welded to the furnace shell. According to the features of claim 2, the compensator penetrates here a breakthrough in the furnace shell and is then either inside the breakthrough or fixed to the outside of the furnace shell by welding. This Arrangement has due to the improved accessibility to the outside of the Furnace main advantages in terms of assembly technology.
  • the space between the cooling plate and the furnace shell shed with a refractory material.
  • the compensator within of a jacket extending between the cooling plate and the furnace shell is.
  • the jacket serves as a shield against the refractory casting compound.
  • This can be a tube attached to the cooling plate, which over there is a seal on the inside of the furnace shell.
  • the coat is in the distance arranged to the compensator.
  • the compensator is one of several Coolant pipes penetrated. That a single compensator can work simultaneously enclose several coolant pipes. It is conceivable that the compensator two, encloses three, four or even more coolant pipes.
  • the compensator is included designed accordingly large and can, depending on the arrangement of the coolant pipes have a shape deviating from the circular shape.
  • Another benefit of combining multiple coolant tubes within one The compensator is that the number of openings in the furnace shell is reduced can. This is advantageous both in terms of production technology and in terms of statics of the furnace.
  • the coolant tubes releasably with the Cooling plate are connected.
  • the naturally also cohesive Connection can be replaced by a screwed connection or even by a suitable coupling between the cooling plate and the coolant pipe.
  • a Detachable connection has the advantage that if the compensator leaks it is more easily accessible for repair.
  • the detachable connection can also be in the form of a on the back of the cooling plate releasably attached flange be given (claim 6).
  • This flange is for example, fixed with screws and can be done with simple assembly tools be removed from the cooling plate.
  • the coolant tubes have at least one thermal one Have flexible longitudinal section compensating for expansion movements, as is provided according to claim 7. It is conceivable that the Coolant pipes at least in their transition area to the cooling plate from one flexible hose consist of a suitable flange or a Coupling element is connected to the cooling plate. This is the assembly and Disassembly of a cooling plate is considerably simplified.
  • FIG. 1 shows a cooling plate 1 with four vertically extending in this representation Coolant channels 2.
  • the coolant channels 2 each open into an outlet opening 3, to each of which a coolant tube 4 is connected (FIG. 2).
  • the coolant pipes 4 serve to supply and discharge a coolant, not shown.
  • Each coolant tube 4 is concentric with the coolant tube 4 arranged, in cross section circular compensator 5 surrounded.
  • compensators 5 are metallic bellows can be designed in one or more layers. The advantages of multi-layer Expansion joints are more flexible with the same overall bellows thickness.
  • the compensators 5 surround the coolant tubes at a radial distance that is so dimensioned that even at maximum thermal stress Cooling plate no direct contact between the compensators 5 and Coolant pipes 4 takes place.
  • the compensator 5 is via a flange 12 in the form of the outlet opening 3 in Distance radially surrounding ring attached to the back 7 of the cooling plate 1 and extends in the direction of the furnace shell 9 into the opening 11, where it welded gas-tight to the furnace shell 9 by a circumferential weld 13 is.
  • the compensator 5 is dimensioned in its outer circumference so that it with a a game allowing installation can be introduced into the opening 11 and finally over the one adjacent to the outside 14 of the furnace shell 9 Weld 13 in the form of a fillet weld can be welded to it.
  • the coolant tube 4 is straight in this embodiment and has on its end 15 facing away from the cooling plate 1, the possibility for one Connection to a coolant supply system.
  • Fastening bolts 16 are arranged, via which the cooling plate 1 on the furnace 9 is fixed in terms of screw technology.
  • the one on the outside 14 of the furnace shell 9 adjacent head 17 of the fastening bolt 16 is covered with a cap 18, the is welded gas-tight to the outside 14 of the furnace shell 9.
  • the cooling plate 1 is on the inside of the furnace, not shown, with dovetail undercuts 19 provided for fixation a fireproof lining.
  • FIG. 3 The embodiments of Figures 3 to 5 differ from that of Figure 1 in that not only a single coolant tube through one Compensator is guided, but several coolant tubes through one accordingly larger compensator are performed.
  • the compensator 22 for the In the exemplary embodiment in FIG. 3, coolant tubes 20, 21 have one Rectangular shape with rounded corners.
  • the advantage of this embodiment is there too see that the outer coolant channels 23 in the lower region of the cooling plate 1 a are angled, and their outlet openings are now also in the middle Area of the cooling plate 1 a are placed. It stands for others Construction elements, especially for fastening bolts, more freedom in the Corner area of the cooling plate 1 a available.
  • the fastening bolts 24 are therefore in the corner region of the cooling plate 1 a arranged to compensate for the delay prevailing here.
  • the arrangement of the individual fastening bolt 24 is of course dependent on the Configuration of the individual cooling plates, in particular from the course of the respective coolant channels.
  • FIG. 4 relates to a slightly narrower width Cooling plate 1b, in which only three coolant channels 25, each running vertically are provided, which in turn in the central lower region of the cooling plate 1 b with regard to their outlet openings from the rear of the cooling plate 1 b are merged.
  • the associated coolant pipes 26 are in turn within a common compensator 27 arranged due to the lower Space requirement of only three coolant tubes 26 is designed narrower than in the Embodiment of Figure 3.
  • the coolant tubes 26 are in terms of their spatial arrangement in the form of a triangle, the compensator 27 is again rectangular with rounded corners.
  • the compensator 27 to the respective drilling pattern Outlet openings 3 adapted, that is configured here triangular in cross section embody.
  • the fastening bolts 28 arranged between the coolant channels 25.
  • two coolant tubes 29, 30 are inside each a common compensator 31 is arranged. While it is possible in principle would be, all coolant tubes 29, 30 similar to the embodiment of Figure 3 through a common breakthrough in the furnace shell, not shown lead and provide a correspondingly large compensator, it can certain configurations may be appropriate to smaller compensators use, as is the case with the cooling plate 1 c of Figure 5. This is particularly so then advantageous if not all coolant channels or their outlet openings like this can be closely merged into one that is as compact as possible Compensator can be used. Since in the embodiment of FIG Distance of the coolant tubes 29 is significantly larger than the distance Coolant tubes 20 of Figure 3, it is in this course of the coolant channels to provide two individual compensators 31, each with two coolant tubes 29, 30.
