Definitions

  • the invention relates to a continuous casting mold with the casting cross-section delimiting copper plates, in which a water tank facing, coolant channels for the cooling water run perpendicular to the casting cross-sectional plane, and in each case a water box tightly fixed per casting cross-section side on the copper plates, to which the coolant channels of the copper plates with a collecting flow and a collecting return are connected.
  • Such a continuous casting mold is known from DE 198 35 111 A1.
  • Water boxes are used to cool such continuous casting molds.
  • the water boxes take on the task of leading the mold cooling water to the copper plates and at the same time supporting the copper plates.
  • All water-carrying parts, especially the water tank, are made of stainless steel.
  • the complete inner and outer water box walls are made of stainless steel. This results in considerable material costs, which make the continuous casting mold more expensive. So far, it has not been possible to change the system of the water boxes and to limit the expenditure on stainless steel.
  • the invention has for its object to reduce the proportion of stainless steel in water tanks and thereby manufacture the continuous casting molds more economically.
  • a copper mold plate is adapted to the pouring cross-sectional profile and has coolant bores running in the pouring direction for the coolant guidance and transverse collection feed and collection return bores connected in at least two, separate, channel-shaped bores Stainless steel water boxes open, the water boxes being placed directly and tightly from the outside onto the copper plate.
  • the mold plates are not supplied with cooling water through cooling slots that are open to the rear, as is usual with all other formats, but rather the cooling water is passed through cooling bores, which are at the top and bottom of the copper plate through collecting holes through the relatively small stainless steel water boxes with cooling water operate.
  • the invention is therefore particularly suitable for producing casting strands in addition to casting strands having a rectangular or square cross section. According to further features, it is advantageous that the profile casting cross section of the copper plates is adapted to a pre-profile casting strand.
  • such an application advantageously results from the fact that the profile casting cross section of the copper mold plate forms a dog-bone profile.
  • the water box for a copper molded plate consists of two spaced-apart and transverse to the casting direction, made of stainless steel elongated channel housings, which are laterally connected by means of a carrier plate and on the copper molded plate lie tight.
  • the carrier function is fulfilled here by the carrier plate made of a material that does not have to be expensive, since no cooling medium is carried in the middle area.
  • Stainless steel can also be saved further because the duct housing has walls on only three sides.
  • a carrier plate can be made from normal steel, ie from a largely unalloyed steel.
  • a further embodiment provides that within the width of a channel housing, a plurality of connection bores from the copper molded plate each open into the respective channel housing. The length of the channel housing can determine the number of connection bores to be accommodated.
  • connecting bores run obliquely or vertically from the copper molded plate into the channel housing.
  • the cooling is carried out in such a way that the connecting bores are each connected to a plurality of coolant bores arranged around the dog-bone profile and running perpendicular to the casting direction.
  • the manufacture of the coolant channels is carried out according to the further invention in that the coolant bores running in the casting direction are made continuously in the copper mold plate and are closed at least on one side by means of end plugs.
  • connection flange is arranged at the ends of the channel housings.
  • the connection flanges can be made of stainless steel, but can also be made of normal steel.
  • Fig. 1 shows a horizontal cross section through the continuous casting mold
  • the continuous casting mold 1 has a casting cross section 1 a at the entrance, which is formed in the casting cross section plane 1 b.
  • the pouring cross section 1 a is delimited by copper plates 2, on the side of which facing away from the pouring cross section 1 a, a water box 3 is arranged.
  • Coolant channels 4 are incorporated in the water box 3 within the copper plates 2, which run perpendicular to the casting cross-sectional plane 1b.
  • Such a water box 3 is provided for each copper plate 2 in order to transfer the heat of the casting metal to be dissipated from the casting cross section 1a into the cooling water.
  • a collection flow 6 and a collection return 7 are provided, which feed the cold cooling water to the coolant channels 4 or collect the heated cooling water from the coolant channels 4.
  • a molded copper plate 2a is provided, the inner side of which is adapted to the pouring cross-section side 5.
  • the copper mold plate 2a does not have cooling slots, as is otherwise customary on such copper plates 2, but rather coolant bores 9, which run parallel to the casting direction 10.
  • the arrangement of the coolant bores 9 follows the pouring cross-section 8.
  • transverse collection feed bores 6a and collection return bores 7a are incorporated, which are connected to the water tank 3.
  • the cross section of the channel housing 13 is U-shaped, so that the channel is open on the sealing side and this also saves on stainless steel.
  • the water box 3 is particularly suitable for profile casting cross sections 11, such as the dog-bone profile 11a shown.
  • a pre-profile casting strand 12 is produced in the continuous casting mold 1 (FIG. 2).
  • the water box 3 consists in each case of two elongated channel housings 13 which are arranged at a distance from the mold ends and which are formed from stainless steel.
  • the channel housing 13 are each laterally connected by means of a carrier plate 14 and lie sealed and fastened on the molded copper plate.
  • the carrier plate 14 can consist of normal steel, ie of simple carbon steel.
  • Within the width 13a of such a channel housing 13, a plurality of connection bores 15 each open, which run in the copper mold plate 2a.
  • the connecting bores 15 can be arranged obliquely upwards or downwards or, as drawn (FIG. 1), parallel to the casting cross-sectional plane 1b.
  • the connecting bores 15 are connected to the corresponding number of coolant bores 9 which are arranged around the dog-bone profile 11a and run perpendicular to the casting direction 10 (FIG. 1).
  • the coolant bores 9 can be produced continuously in the casting direction 10 in the copper mold plate 2a, one side (the upper side in FIG. 2) of the continuous casting mold 1 being closed by means of an end plug 16.
  • connection flanges 17 (not necessarily made of stainless steel) are also fastened at the first end 13b and at the second end 13c of the channel housing 13.

Abstract

L'invention concerne une lingotière de coulée continue (1) qui comprend des plaques de cuivre (2) qui limitent la section de coulée (1a) et dans lesquelles des conduits de réfrigérant (4) sont orientées vers un réservoir d'eau (3). Le réservoir d'eau (3) comprend une entrée collectrice (6) et un retour collecteur (7). L'invention vise à réduire la part d'acier spécial du réservoir d'eau (3). A cet effet, une plaque-modèle de cuivre (2a) est adaptée, pour une section de coulée profilée (1a), au profil de section de coulée (8) et comprend des alésages de réfrigérant (9) parallèles au sens de coulée (10) pour la conduite de réfrigérant ainsi que des alésages d'entrée collectrice (6a) et des alésages de retour collecteur (7a) raccordés s'étendant perpendiculairement, qui débouchent dans au moins deux réservoirs d'eau distincts (3) en forme de conduits en acier spécial. Les réservoirs d'eau (3) sont posés directement et étanches de l'extérieur sur la plaque-modèle de cuivre (2a).
