Definitions

  • the invention relates to a mold for the continuous casting of metal with the features of the preamble of claim 1.
  • the conicity of the hollow shaped body which is location-dependent in the casting direction is a curve which can be described by a continuous function.
  • the concave contours do not start abruptly, but have a smooth, as rounded as possible transition, which can be described by a continuous curve.
  • the contour can also be described by a suitable and sufficiently large number of straight line sections.
  • the contour should be a describable by a ideally continuous function curve.
  • the contour may be composed of straight lines and / or circular sections.
  • the contour of the at least one concave contour may be at least partially, i. optionally in combination with another processing method, produced by a deposition process, e.g. by an etching process, erosion, laser ablation or by electrochemical processes.
  • FIG. 1 shows in longitudinal section the wall of a mold 1 for the continuous casting of metal.
  • the illustration is purely schematic, is in no way to scale and is merely illustrative of the inventive concept.
  • the concave contours 7 start at a certain distance below the predetermined G fauxspiegel position and extend to the outlet opening 4.
  • the geometry of the contours 7 is chosen so that there is an optimum line with regard to the conicity, which is defined neither by the deepest 9 nor the edge 8 of the contours 7, but by the superposition of all conicities.
  • the embodiment of the FIG. 7 differs from the previous one in that the radius of the contours increases in the casting direction. It can be seen that the radius R2 at the narrow end of the contour 7b is smaller than the radius R3 at the broad end of the contour 7b.
  • This geometry results from a penetration of the mold plate 12 with a circular cone, wherein the vertical axis of the circular cone runs parallel to the surface of the mold cavity. Of course, this circular cone can also be additionally inclined to vary the depth and width of the contour 7b. Also in this embodiment, the edges 8 of the contour 7b are rounded, so that on the exit side results in a sense a corrugated profile.
