Definitions

  • the invention relates to a continuous casting mold with copper plates enclosing the casting cross section, in which cooling channels run, and the copper plates are connected by means of screw elements to a steel water tank, the screw elements consisting of fastening bolts with a threaded shaft that can be screwed into the copper plate.
  • a known construction follows from DE 198 42 674 A1, the inner mold plate on its side facing the water tank having webs with grooves running therebetween with a groove width in which filler pieces are arranged.
  • the grooves have undercuts with an undercut thickness, furthermore that the filler pieces have connecting elements with a connecting element thickness and that the filler pieces releasably engage in the undercuts and the screw connections between the filler pieces and the Water box are arranged. While this training solves some problems, it does not require insignificant assembly and manufacturing costs.
  • the attachment designs listed above are associated with various disadvantages. Tapped holes require larger distances between the cooling slots and hinder or change the heat dissipation from the copper plate to the cooling water.
  • the invention has for its object to provide a fastening of copper plates for continuous casting molds, in which all fastening bolts are reliably loaded with the same force, the break is not deformation-free, the heat dissipation from the mold is largely uniform and the attachment no additional increase in the copper plate thickness requires.
  • the object is achieved according to the invention in that the fastening bolts with their central longitudinal axes are each arranged centrally between two adjacent coolant bores arranged in the copper plate parallel to one another and transversely to the central longitudinal axis.
  • the distance between the coolant holes can be of the same size or approximately the same size over the entire mold area and also does not have to be selected larger in the area of the mounting holes, as a result of which the heat dissipation is more uniform and only slight temperature differences occur on the front side of the mold.
  • fastening bolts no longer have to be arranged one below the other in the casting direction, but can instead be offset.
  • the number and distribution of the fastening bolts can thus be adapted to the local loads.
  • One embodiment provides that the fastening bolts cut the two adjacent, transverse coolant bores on their circumference. Nevertheless, the cooling effect is not significantly impaired and the previous spacing of the cooling holes with a cylindrical cross section can be retained.
  • a further development provides that the fastening bolt is screwed into an adapter, the adapter having its central longitudinal axis running centrally between the coolant holes running transversely in the copper plate.
  • the distance between the coolant holes need not be chosen to be very large and can be the same size over the entire cooling surface and does not have to be larger in the area of the mounting holes.
  • the fastening bolts are attached to the adapter and thus ensure the connection of the copper plate to the steel frame of the water tank.
  • the use of adapters additionally reduces the bending load on the fastening bolts, which are connected to the adapters by means of the thread. The thread acts like a joint here.
  • the adapter cuts the two adjacent, transverse coolant bores on their circumference with its threaded shaft. As a result, the screw connections protrude into the coolant bore at some points. Due to their favorable profile, only a slight influence on the cooling water flow is to be expected in the flow direction of the coolant.
  • Another embodiment provides that the adapter is embedded in a recess in the water tank. This creates an advantageous space in the water tank so that the adapter is only a short distance from the copper plate.
  • the escape of water from cut coolant bores can be prevented by sealing the adapter against the copper plate by means of a seal.
  • the proposed invention is particularly suitable for the attachment of thin-walled funnel molds.
  • Such continuous casting molds are produced according to a special method in such a way that the cooling channels consisting of coolant bores in the copper plate are drilled prior to further processing, then the copper plate is preformed and processed by pressing onto the mold shape and that the fastening internal thread for the adapter or the fastening bolt is cut into.
  • the coolant holes can be drilled into the copper plate as straight, continuous holes before the forming and then be reshaped with h- Das-Bringer of kinking holes from two sides as before.
  • FIG. 1 shows a vertical section through the copper plate with the water tank of a continuous casting mold
  • FIG. 2 shows a horizontal section A-B according to FIG. 1.
  • the copper plates 1 enclose a casting cross section, not shown, which can be rectangular or square, for example.
  • Coolant bores 2 with a cylindrical circular cross section run in the copper plate 1.
  • the copper plate 1 is connected by means of screw elements to a water tank 5, from which the cooling water is pumped into the coolant bores 2 and, after absorbing heat, is discharged again for re-cooling.
  • the screw elements here consist of fastening bolts 3 with a threaded shaft 3b which is screwed into the copper plate 1.
  • the fastening bolts 3 with their central longitudinal axes 3a are each arranged centrally between two adjacent coolant bores 2 arranged in the copper plate 1 parallel to one another and transversely to the central longitudinal axis 3a.
  • the fastening bolt 3 can cut the two adjacent, transverse coolant bores 2 on their circumference, as can be seen from FIGS. 1 and 2.
  • the fastening bolt 3 is alternatively screwed into an adapter 4, the adapter 4 being screwed with its central longitudinal axis 4a centrally between the coolant bores 2 running transversely in the copper plate 1.
  • the adapter has external thread 6, which is screwed into the copper plate 1, and internal thread 7, into which the fastening bolt 3 is screwed. Analogous to that the copper plate 1 fastening internal thread 1a. It may be desired that the adapter 4 cuts the two adjacent, transverse coolant bores 2 on their circumference with its threaded shaft 4b.
  • the adapter 4 is embedded in a recess 9 in the water tank 5, as a result of which the "joint" moves closer to the copper plate 1.
  • the adapter 4 is sealed against the copper plate 1 by means of a seal 8.
  • the production of the mold plate 1 from copper, in particular for a funnel-shaped continuous casting mold with a constant plate thickness, into which the cooling channels are introduced, takes place in such a way that the cooling channels consisting of circular-cylindrical coolant bores 2 in the copper plate 1 are just drilled before further processing, after which the Copper plate 1 is preformed and pressed onto the mold and then the internal thread 1a for the adapter 4 or the fastening bolt 3 is cut.

Abstract

L'invention concerne une coquille pour coulée continue comportant des plaques de cuivre (1), qui entourent la section de coulée et dans lesquelles se trouvent des canaux de refroidissement. Ces plaques de cuivre (1) sont reliées par des pièces de boulonnerie à un réservoir d'eau (5) en acier, ces pièces étant des boulons de fixation (3) dotés d'une tige filetée qui se visse dans la plaque de cuivre (1). Ces éléments de fixation résistent aux sollicitations de même intensité. La rupture ne se produit pas sans déformation. L'évacuation de la chaleur est uniforme. La fixation ne nécessite pas d'augmentation supplémentaire de l'épaisseur des plaques de cuivre. L'invention est caractérisée en ce que l'axe médian longitudinal (3a) des boulons de fixation (3) est disposé au centre entre deux orifices d'agent de refroidissement (2) voisins, ces orifices étant façonnés dans la plaque de cuivre (1) parallèlement l'un sous l'autre et transversalement par rapport à l'axe médian longitudinal (3a).
