Definitions

  • the invention relates to a mold tube for the continuous casting of metals according to the features in the preamble of patent claim 1.
  • the invention is - based on the prior art - the object of the invention to provide a mold tube for the continuous casting of metals, which has an improved life and in which local overheating be avoided.
  • the distance between two adjacent cooling channels in the transitions is smaller than the distance between adjacent cooling channels in the other wall sections.
  • the cooling channels can basically emerge in all wall sections on the end faces of the pipe wall. In these areas, it is easily possible for a trouble-free installation and a secure sealing of a mold tube after recalibration to perform welds, which are then post-recalibrated easily to Neuwait.
  • cooling channels are provided with a round cross section, there is the further advantage after bending a tube mold to a beam blank format, that in this case also the cross sections of many cooling channels are deformed oval, in the sense that the surface areas for Enlarge pouring channel, so that can be expected with a higher heat dissipation.
  • a second Lössung consists in the features of claim 2. Thereafter, it is also possible to provide cooling channels only in the rounded transitions, while the remaining wall sections and the rounded transitions are cooled by a matched to the outer contour of the pipe wall Wasserleitmantel. In this solution, not the entire pipe wall is interspersed with cooling channels. Rather, cooling holes are present only in the areas in which local overheating would lead to a reduction in the service life of the mold tube. By combining a water jacket with introduced into the rounded transitions of the pipe wall cooling channels local overheating in the rounded transitions can be avoided and the life of the mold tube can be increased.
  • the cooling channels provided in the transitions may extend from the upper end side of the pipe wall to approximately the middle height region of the pipe wall.
  • cooling medium supply and cooling medium discharges to a separate cooling circuit.
  • the cooling medium flowing between the pipe wall and the water-conducting jacket can also flow through the cooling channels and ensure intensive heat dissipation in areas subjected to higher thermal stresses (claim 7).
  • suitable conductive means may be provided on the outer contour of the pipe wall and / or the Wasserleitmantel, which direct the flow of the cooling medium in the cooling channels.
  • the features of the invention are particularly advantageous in a mold tube with a double-T-shaped cross section according to claim 8 noticeable.
  • the mold tube is preferably made of copper or a copper alloy.
  • FIGS. 1 and 2 a mold tube in the beam blank format is designated in FIGS. 1 and 2.
  • the mold tube 1 has a double-T-shaped cross-section with a constant over the entire circumference thickness D of the tube wall. 2
  • the inner contour 3 of the mold tube 1 determines the cross section of the cast strand.
  • cooling channels 4 are provided in the tube wall 2 extending over the entire length L of the mold tube 1, which are acted upon in accordance with the arrow KW from bottom to top with cooling water. That is, the cooling channels 4 terminate in the end faces 5 of the tube wall 2, wherein only one end face 5 can be seen.
  • the cooling channels 4 are introduced by a Bohroperation in the pipe wall 2, and that before the mold tube 1 is bent. By bending the cooling channels 4 can then partially deform so oval that the inner contour 3 towards larger surface areas are formed, whereby the heat dissipation is improved.
  • the specific inner contour 3 of the mold tube 1 has rounded transitions 6 between a flange region 7 on the one hand and a wall region 9 delimiting a web region 8 on the other hand.
  • the distance A between two cooling passages 4 adjacent to one another in the transitions 6 is smaller than the distance B in the remaining wall sections 9.
  • cooling channels 4 While in the embodiments of Figures 1 and 2, the cooling channels 4, the Kokillenrohre 1 enforce over its entire length L, it is also conceivable that provided in the transitions 6 cooling channels 4 from the upper end face 5 of the pipe wall 2 to about the middle height range the pipe wall 2 extend. These cooling channels 4 can be connected to one another to form a cooling circuit at their upper end sides and fed viamémediumzu Entryen anddemediumab Entryen in the middle height range of the pipe wall 2 with a cooling medium.
  • the mold tube 1 may be embedded in a matched to the outer contour 10 of the pipe wall 2 Wasserleitmantel, so that the mold tube 1 is surrounded in total by a flow-through with a cooling medium cooling gap.
  • FIG. 3 shows, in a somewhat different perspective, another embodiment of a mold tube 11 with an inner contour 12 in the beam blank format, likewise with rounded transitions 13 between, on the one hand, a flange region 14 and, on the other hand, a web region 15 delimiting wall sections 16
  • Embodiment cooling holes 4 are present only in the transition areas 13.
  • the entire mold tube 11 is embedded in a manner not shown in a matched to the outer contour 17 of the tube wall 18 Wasserleitmantel over which both the remaining wall portions 16 and provided with cooling holes 4 transition areas 13 are cooled.
