Definitions

  • the invention relates to a continuous casting mold whose mold walls are provided with a plurality of extending in the vertical direction and connected to a water circulation cooling channels.
  • Molds of this type are well known in the art. They usually consist of copper plates. In order for them to have a sufficient service life, they must be cooled. For this purpose, fundamentally different types of measures are known. Various configurations can be provided for the cooling, wherein in particular cooling slots, cooling slots with filler pieces, deep-hole bores or area-effecting cooling are known and customary.
  • EP 0 968 779 B1 discloses grooves machined into the mold plate, which grooves are closed by a filling piece to form a cooling channel. A similar solution is shown in EP 1 757 385 A2 and DE 101 38 988 A1.
  • the invention is therefore the object of developing a mold of the type mentioned so that a particularly effective cooling possible
  • the cooling should be able to be targeted to desired areas, so that an intensive cooling effect can be generated in these areas, so that the thermally highly stressed areas of the copper plate of the continuous casting mold will have a longer service life be lent.
  • cooling channels are formed in an upper region of the mold by a number of holes and that the cooling channels are formed in a lower portion of the mold by incorporated into a part of the mold grooves, the formation of at least one filler a channel are closed.
  • the cooling channels are preferably formed in the upper or lower region of the mold exclusively by holes or grooves together with filler.
  • the upper region preferably extends over 25% to 75% of the total mold height, more preferably over 40% to 60% of the mold height.
  • the cooling channels of the upper region can merge into the cooling channels in the lower region in a transition region.
  • grooves closed by filling can be arranged parallel to the wall of the mold. It can also be arranged parallel to the wall of the mold more holes. At least in sections, two, three or more rows of bores can furthermore be arranged in a horizontal direction parallel to the wall of the mold.
  • the bores and / or at least a portion of the grooves can, seen in the vertical direction, run parallel to the wall of the mold.
  • the bores and / or at least a portion of the grooves can, viewed in the vertical direction, also run at an angle to the wall of the mold.
  • All holes can have the same diameter. However, it is proposed that at least two holes have different diameters.
  • the clear width of the grooves in the lower region of the mold is greater than the diameter of the bores in the upper region of the mold.
  • An improved cooling effect induces less thermal stress in the copper plates that make up the continuous casting mold.
  • the plate temperature distribution is therefore uniformed, in particular in the upper region of the plate or mold.
  • the temperature on the hot and on the cold side is reduced in the critical bath level range.
  • Manufacturing technology is advantageous that a favorable combination production is possible, consisting of the introduction of straight slots for the grooves and the downhole holes, due to the concept of the invention are much shorter than in the prior art, which is why the deep hole drilling is much easier to control.
  • the potential of the plate increases for a smaller plate thickness and for a high casting speed.
  • FIG. 2 shows the section A-B according to FIG. 1.
  • FIG. 1 the right side boundary for the metal to be cast is shown as a detail of a continuous casting mold 1.
  • the level is clarified by the pouring mirror 10. Accordingly, the wall 9 of the mold 1 is exposed to the hot metal and must be cooled.
  • the wall 9 forming plate consists in a known manner of copper.
  • the mold 1 is funnel-shaped, d. H. the upper area of the wall 9 is oriented at an angle ⁇ i to the vertical V.
  • cooling channels 2 For cooling the mold 1, this is provided with cooling channels 2. It is provided that in an upper region 3 of the mold 1, a different type of cooling or training of the coolant supply is made as in a lower region 5 of the mold 1, to improve the cooling intensity at the scene significantly.
  • the cooling channels 2 are formed exclusively by holes 4, which are introduced as tie-holes in the copper plate, which forms the mold wall 9.
  • the cooling channels 2 are formed in the lower region 5 of the mold 1 by incorporated into a part of the mold 1 grooves 6, which are closed by at least one filler 7 to form a channel.
  • the holes 4 extend to the vertical V at an angle ⁇ j> 2 . Since this is the case in the region in which the wall 9 of the mold over a present at the same angle ⁇ -i to the vertical V, this has the result that the holes 4 here parallel to the wall 9 in the interior of the mold plate run.
  • the bores 4 on the one hand are not all provided with the same diameter and, on the other hand, are not only arranged in a single row. assigns.
  • FIG. 2 shows the section AB according to FIG. 1. It can be seen that a number of holes 4 are provided with a relatively large diameter D, but next to holes 4 with a smaller diameter d, the holes 4 with the smaller diameter more rows - in the present double row - are arranged.
  • the arrangement of the holes 4 may be two, three or more rows at least over parts of the mold extension.
  • grooves 6 slots
  • filling pieces 7 in the lower part of the mold and deep holes in the upper part of the mold plate below the mold level 10 can by a larger number in diameter smaller holes 4 (preferably diameter below 11 mm) and in depth limited holes a zone of high cooling intensity, ie an intensive cooling zone can be generated.
  • the holes 4 in the upper region 3 of the mold 1 can be made due to the relatively short extent with relatively small diameters and introduced with high precision. Furthermore, the bores 4 can be arranged and staggered in succession so that high water velocities can be achieved with a large covering surface. As a result, a plate is produced with a zone of high cooling intensity.

Abstract

L'invention concerne une lingotière de coulée continue (1) dont les parois sont dotées de plusieurs canaux de refroidissement (2) s'étendant dans une direction verticale et raccordés à un circuit d'eau. Afin d'obtenir un meilleur refroidissement de la lingotière, l'invention prévoit que les canaux de refroidissement (2) soient formés dans une partie haute (3) de la lingotière (1) par un certain nombre d'alésages (4) et que les canaux de refroidissement (2) soient formés dans une partie basse (5) de la lingotière (1) par des rainures (6) ménagées dans une partie de la lingotière (1) qui sont fermées par au moins une pièce de remplissage (7) en formant un canal.
