Definitions

  • the invention relates to a liquid-cooled plate mold for the continuous casting of metals, in particular, of steel materials, comprising highly heat-conductive mold plates of copper or copper alloys which are connected by means of fastening bolts with a fastening support in the form of a water box or a support plate, respectively.
  • the patent document DE 197 16 450 A1 describes a liquid-cooled mold for continuous casting of thin steel slab with two oppositely positioned wide sidewalls, each comprised of a copper plate and a steel support plate.
  • the copper plates which delimit a cavity of the mold, are detachably connected by means of metal bolts of a CuNiFe alloy to the support plates.
  • the metal bolts are welded onto the copper plates.
  • a nickel ring is additionally used as a welding additive.
  • cooling medium channels are provided, and cooling medium bores are provided in the area of the transverse section planes of the metal bolts.
  • the gist of the aforementioned mold is the feature that metal bolts of a CuNiFe alloy are being used.
  • the patent document WO 95/21 036 describes an assembly group of a mold for continuous casting of steel with a support plate.
  • a copper or copper alloy plate with excellent heat conducting properties is screwed onto the support plate and a relatively thin cover layer of copper or copper alloy is soldered onto the copper plate.
  • the plate with excellent heat conducting properties can be omitted and the cover layer can be soldered directly onto the support plate.
  • the cover layer contacts and cools the cast strand passing through when moving through the mold. When the cover layer shows cracks or wear, the solder connection is melted in order to remove it and a new layer is soldered onto the thermally conductive layer or the support plate.
  • the patent document DE 198 01 728 C1 discloses a continuous casting mold for casting strands of, preferably, steel.
  • the mold is comprised of mold plates and water boxes which are connected to one another and between which a water cooling system is provided with the aid of water guiding channels.
  • the water guiding channels are arranged at the side of the water box facing the mold plate and not within the mold plate.
  • a continuous casting mold of this configuration is improved in that the wide side of the mold with its elements copper plate and/or water box with water guiding channels or with a water box without water guiding channels, but with a connecting plate having water guiding channels, is secured by means of clamping bolts. They have substantially conical clamping bolt heads which are secured in conical recesses of the copper plate.
  • the bolt head of the clamping head should have a special conical shape or be conical-lamella-shaped, and, advantageously, should be comprised of the same material as the copper plate of the continuous casting mold.
  • the surfaces between the copper plate and the clamping bolt/clamping bolt head can be provided with a highly conductive layer of metal, preferably silver.
  • a further improvement of the connection of the copper plate and clamping bolt is achieved when the connection is provided on the cold side of the copper plate with a seal against water passage across the surface in the direction of the hot side.
  • the patent application DE 198 35 119.9 concerns a mold wall of a continuous casting device for casting a metal strand, in particular, a steel strand, with a water box and an inner mold plate connected by bolts to the water box.
  • the bolts have a bolt neck, respectively, penetrating the water box and having a bolt neck cross-section, and a bolt head, secured in the inner mold plate and having a bolt head cross-section.
  • the bolt head cross-section of at least one of the bolts is greater than the bolt neck cross-section of this bolt, and that the inner mold plate has a groove which tapers in a direction toward the water box for receiving the bolt head of this bolt.
  • German published document 15 08 902 discloses a liquid-cooled plate mold for continuous casting of high-melting metals in which a mold wall is connected by fastening screws to a support frame. Round rods are provided which are inserted into bores of the mold wall transverse to the casting direction and are provided with threaded bores for receiving fastening screws. The assembly expenditure for this configuration is considerable.
  • soldering connections and/or welding connections can be produced easily, on the one hand, and have fatigue strength under reversed stresses of, for example, 100 N/mm 2 , on the other hand.
  • the shaped parts or fastening pieces are preferably produced of a material with excellent conducting properties such as CuAg, CuCrZr, CuNiBe, or CuNiFe.
  • the fastening pieces can be connected by a soft solder layer with high shearing strength with the mold plates.
  • the fastening piece can also be inserted into a shallow, round recess of relatively minimal depth at the backside of the mold plate.
  • the welding connection is then carried out annularly along the separating location between the mold plate and the fastening piece.
  • the electron beam can impinge perpendicularly or at an angle onto the surface of the mold.
  • the fastening pieces can be provided with a step or shoulder which is of such a size that it is flush with the upper rim of the recess, as illustrated in FIG. 2.
  • the fastening pieces as described above, can be produced of a metal material of good conducting properties or a suitable steel alloy.
  • FIG. 1 is a section of a portion of an inner mold plate with a shaped part attached by soldering and fastening bolts of a support plate screwed into the shaped part;
  • FIG. 2 shows in section a detail of FIG. 1 with the shaped part attached by electron beam welding.
  • the part of a liquid-cooled plate mold illustrated in FIG. 1 for continuous casting of high-melting metals, such as steel, comprises a highly heat-conductive mold plate 1 of copper or copper alloy which is connected by means of fastening elements in the form of fastening bolts 2 on a fastening support.
  • the fastening support can be a water box, e.g., the backside of the water box, or a support plate 4 provided with channels 3 for the cooling water.
  • the channels for the cooling water can also be located within the mold plate.
  • shaped parts 6 with threaded bores 5 for screwing in the fastening bolts 2 are arranged and connected by a non-positive connection with the mold plate 1 by means of soldering connections 7 , 7 ′ in order to provide fastening pieces.
  • the shaped parts or fastening pieces 6 are preferably produced of a metal material having good conducting properties such as CuAg, CuCrZr, CuNiBe, or CuNiFe.
  • the fastening pieces 6 are connected by a soft solder layer 7 with the mold plates 1 .
  • the soft solder layer 7 with a high shearing strength is preferably produced of a solder material of the alloys L CdZn or L CdZnAg or L SnCdZn.
  • solder metal is preferably copper solder alloy or a silver solder alloy.
  • the hard solder connection provides at soldering temperatures above approximately 450° C. a comparatively high strength in comparison to a soft solder connection; however, in comparison to the soft solder connection, it is somewhat more prone to solder fractures when subjected to changing temperatures and requires a higher expenditure during manufacture and cannot be removed (by melting) without affecting the surrounding material, in particular, copper, in the case of repairs.
  • One embodiment of the invention suggests that the soldering surface of the mold plates for the fastening pieces 6 is metallized for an exact positioning of the fastening pieces 6 .
  • the fastening pieces 6 are shaped parts with preferably annular cross-section which are inserted into congruent shallow recesses 8 of relatively minimal depth (see FIG. 1), for example, up to 5 mm, in the backside of the mold plate 1 and are soldered therein, and that the support plate 4 has a cooling medium bore 9 having a spacing on all sides relative to the fastening piece 6 positioned in the bore 9 and being in flow communication with at least one cooling medium channel 3 .
  • the cooling medium bore 9 can also be provided in the plate of the water box.
  • This configuration of the bolt attachment has the advantage that the fastening piece 6 as well as the shaft of the bolt 2 are exposed to the flow of cooling water and are therefore sufficiently cooled. Thus, the endangerment of the solder connections is reliably prevented.
  • each of these annular gaps 10 is connected with a cooling medium bore 9 supplying cooling water.
  • the aforementioned embodiment has furthermore the advantage that temperature-caused expansion differences between the mold plate 1 and the support plate 4 can be compensated easily.
  • cooling medium channels 3 in the mold plate 1 can be configured either as grooves or as channel bores extending preferably in the casting direction.
  • FIG. 2 shows in section a detail of FIG. 1 with the shaped part 6 , which, as an alternative solution of the aforementioned object, is fixedly connected by an electron beam welding seam 12 with the mold plate 1 .
  • the welding seam is positioned at the exterior side of the shaped part (fastening piece) 6 .
  • the outer diameter of the shaped part which in cross-section is annular, has a diameter which is greater by 1 to 8 mm in the area of the welding seam 12 .
  • the mold plate 1 can have in the area of the attachment a minimal material projection which corresponds approximately to the height of the welding seam depth.
  • the shaped part (fastening piece) 6 is provided with an inner thread 5 for attachment of the fastening bolt 2 (FIG. 1).
  • the shaped part can also be in the form of a bolt with outer thread.
  • the channels 3 of the support plate 4 for supplying cooling water are indicated only partially, and the bore 9 supplying the cooling water is also only partially indicated.
