Definitions

  • the invention relates to a mold tube with a double-T-shaped inner and outer cross-section in the beam blank format according to the features in the preamble of patent claim 1.
  • the material temperatures in the mold wall resulting from the heat loads occurring during continuous casting and the cooling conditions by the respective cooling medium which usually in the form of water in a water gap between a matched to the outer contour of the mold tube Wasserleitmantel and the outside surface of the Kokillenrohrs flows from bottom to top, this absorbs the heat accumulated and transported away.
  • the removal of heat by means of cooling water is largely determined by the water velocity in the water gap.
  • the invention is - based on the prior art - the object of the invention to provide a mold tube with a double-T-shaped inner and outer cross section in the beam blank format for continuous casting of metals, in which a local overheating of the transition areas avoided and thereby a longer life is achieved.
  • the features of claim 2 provide that the wall thickness is reduced in the transition areas only in the height range of the bathroom mirror.
  • the reduction of the wall thickness of the mold tube in the rounded transition areas can be done in various ways.
  • trough-shaped recesses are provided outside of the transition areas.
  • the curvature of the recesses in this case can be largely adapted to the curvature of the inner surface of the transition regions.
  • the wall thickness reduction in the form of trough-shaped recesses has the advantage that the outer surface of the mold tube is increased, so that an even better cooling effect can be achieved.
  • a plurality of longitudinally directed, adjacent grooves are provided on the outside of the transition regions.
  • the cross-section and / or the depth of the grooves may be the same or different in each transition region.
  • the cross section of the grooves may be rounded or angular, e.g. be triangular.
  • a plurality of longitudinally directed, side by side extending bores are provided to reduce the wall thickness in the wall portions of the transition regions.
  • the size of the holes, their number, the distance from each other and also their position in relation to the outer or inner contour of the Kokillenrohrs may vary. It is advantageous, however, if the holes have a greater proximity to the outer surface than to the inner surface of the mold tube.
  • the embodiment according to the features of claim 6 provides that the Wasserleitmantel has a rectangular cross-section and between the Wasserleitmantel and the webs or flanges are incorporated into the formed by the outer contour of the Kokillenrohrs and the inner contour of the Wasserleitmantels cross-sectional area matched patches.
  • a mold tube with a double-T-shaped inner and outer cross-section in the beam blank format is denoted by 1 in FIGS.
  • the mold tube 1 is used for continuous casting of metals.
  • the curvature of the mold tube 1 is not shown in the longitudinal direction.
  • the wall thickness D of the mold tube 1 in the rounded transitional areas 2 is smaller than the wall thickness D1 in the remaining wall sections, from the central webs 4, which are located opposite one another and are inclined towards the longitudinal axis 3, on the adjacent inclined flanges 5 6 and 7.
  • the wall thickness reduction takes place in the embodiment of Figures 1 to 3, characterized in that the outside of the transition regions 2 longitudinally directed trough-shaped recesses 8 are provided. These recesses 8 extend, as the figure 2 reveals, only in the height range of the not further illustrated bath mirror.
  • the curvature 9 of the recesses 8 is largely adapted to the curvature 10 of the inner surface 11 of the mold tube 1 in the transition regions 2.
  • these channels 15 are provided with patches 17, which in the upper area also are adapted to the trough-shaped recesses 8.
  • FIG. 4 Four different embodiments are shown in FIG. 4, as the wall thickness reduction of the mold tube 1 can also be realized.
  • a plurality of longitudinally directed, adjacent grooves 18, 18a, 18b are provided on the outside. While in the transition region 2a, the grooves 18 have a triangular cross-section, the grooves 18a, 18b in the transition regions 2b, 2c have rounded bottoms. In this case, the grooves 18b have a greater depth in the transition region 2c than the grooves 18a in the transition region 2b.
  • the wall thickness reduction is realized by holes 19. These holes 19 are closer to the outer surface 13 of the mold tube 1 as the inner surface eleventh
  • Both the grooves 18, 18a, 18b and the holes 19 extend, as the recesses 8, only in the height range of the bath level.
