Definitions

  • the invention relates to a method for producing a mold tube made of copper or a copper alloy for a continuous casting mold according to the features in the preamble of patent claim 1.
  • Mold tubes usually have a uniform wall thickness in a horizontal cross-sectional plane, which increases in the strand direction due to the internal conicity of the mold tube.
  • the internal conicity is adapted to the solidification behavior of the strand and the continuous casting parameters.
  • the heat dissipation is predominantly two-dimensional and leads to a very different cooling of the steel strand.
  • the cooling performance is lower than in the corner areas due to the approximately same ratios of casting surface to cooling surface. At the same time a higher heat flow is impressed. This leads to a reduced shell growth in relation to the corner areas.
  • a higher heat dissipation can be achieved by additional cooling grooves, as described for example in EP 1 792 676 A1.
  • the cooling grooves are adapted in their depth and arrangement to the dissipated heat amount, wherein the corner regions of the mold tube are recessed.
  • the grooves are made by machining because they are formed as depressions in the surface.
  • the invention has for its object to provide a method for producing a mold tube, with which Kokillenrohre can be produced inexpensively with optimized heat dissipation. This object is achieved in a method having the features of patent claim 1.
  • the inventive method for producing a mold tube made of copper or a copper alloy provides that a front tube is formed on a mandrel which determines the inner mold of the mandrel by the action of force from the outside and is removed again after the molding process from the mold tube.
  • the front pipe will be there passed through a die, which has a shaping structure for adeproflltechnik on the outside of the Kokillenrohrs, so that thedeproflltechnik is made by means of the die during molding of the front pipe on the dome.
  • the method according to the invention therefore provides for a chipless production of the cooling profile, which is achieved by a special shaping structure in the die.
  • the cooling profile can be produced much faster and more economically than by machining.
  • the cooling profiling is preferably produced by pulling the pre-pipe through the die.
  • the corner regions of the mold tube can be recessed in order not to increase the heat transfer area in this area additionally.
  • the cooling profile itself may be formed as a groove profile with a corrugated structure or as a zig-zag profile.
  • a corrugated profiling or a zigzag profiling can be easier to implement when pulling through the die as individual spaced grooves with, for example, rectangular cross-section.
  • the cooling profile is produced with an amplitude height in a range of 0.5 to 5 mm, wherein in the case of a zigzag profile, an opening angle between two adjacent teeth in a range of 15 to 90 ° and wherein in the case of a wave profile, the distance between two adjacent grooves is 1 to 14 mm.
  • the amplitude height is 0.5 mm to 1, 5 mm.
  • the opening angle is preferably in a range of 45 ° to 60 °.
  • the method according to the invention can be applied to all known forms of mold tubes, be it that the cross section is circular, rectangular or square.
  • T, double, U or L-shaped cross-sectional profiles can be produced by the method according to the invention.
  • the mandrel used in the method according to the invention may be conically shaped. It can be one or more parts.
  • the dome itself can also be curved so that mold tubes for circular arc continuous casting machines can be produced by the method according to the invention.
  • Figure 2 is a sectional view through the edge region of a mold tube with a corrugated Kuhlprofilleiter and
  • FIG 3 shows a perspective view of the corner region of a mold tube.
  • Figure 1 shows a section of a mold tube 1. Specifically, it is a quarter of a mold tube, which limits a rectangular interior in the complete representation.
  • the mold tube 1 therefore has a corner region 2 and side walls 3, 4, wherein the upper side wall 3 in the image plane is longer than the right side wall 4 in the image plane.
  • the mold tube 1 shown is made of copper or a copper alloy and is produced by pulling a Vorrohrs not shown by a die. In this case, the front pipe was molded onto a mandrel also not shown. By force from the outside by means of the die, the inner contour of the mold tube 1 is formed.
  • the geometry of the die determines the outer geometry of the mold tube 1. In the method according to the invention, it is essential to the outer geometry of the mold tube.
  • FIG. 1 shows that the outside 5 has a cooling profiling 6, 7 in some areas and not in other areas. Concretely, the corner portion 2 in this embodiment is smooth, i. H. formed without Kuhlprofiltechnik.
  • the cooling profiles are only in the region of the side walls 3, 4.
  • the Kuhlprofilierung 7 is the right in the image plane, shorter side wall 4 at a slightly greater distance from the corner region 2. That is, the corner region 2 initially passes into a region 8, in which the Outside 5 of the side wall 4 is not rounded and smooth. Only then does the cooling profiling 7 begin.
  • the cooling profiles 6, 7 are identical. These are zigzag profiles.
  • the grooves or grooves of the zigzag profile are identical overall educated. They have a uniform amplitude height H, which is in this embodiment in the order of 0.5 to 1, 5 mm and in particular 1 mm.
  • the angle W measured between adjacent flanks of two prongs is in a range of 15 to 90 degrees. In this embodiment, it is 60 °.
  • the embodiment of Figure 2 differs from that of Figure 1 only in the shape of the cooling profiles 6a, 7a.
  • the cooling profiles 6a, 7a are not formed as a zigzag profile but as a wave profile.
  • the amplitude height is in a range of 0.5 to 5 mm and, in this case too, may preferably be in a range of 0.5 to 1.5 mm, in particular 1 mm. It can be seen that both profilings 6a, 7a are uniform overall.
  • the adjacent grooves 9 between two wave crests 10 are all arranged at the same distance. The distance is 1 to 14 mm.
  • the illustrated angle W1 between the flanks is again 60 °.
  • FIG. 3 shows a perspective view of the corner region 2 of the mold tube 1 shown in FIG. 1.
  • the corner region 2 is smooth on its outer side 5, while a cooling profiling 6 is formed on the left side wall 3 in the image plane.
  • a transverse groove 11 In the image plane above the cooling profile 6 there is a transverse groove 11, as a cut in the side wall 3.
  • Another transverse groove 12 is located in the other side wall 4.
  • the transverse grooves 11, 12 extend into the corner region 2 inside.
  • the mold tube 1 can be fixed.
  • no cooling profiling is no longer arranged.
  • the cooling profiling may, for example, have been removed by machining to provide a smooth surface for sealing the mold tube 2 in a water box.
  • Cooling profiling 6a Cooling profiling
  • Cooling profiling 7a Cooling profiling

Abstract

L'invention concerne un procédé de fabrication d'un tube de lingotière constitué de cuivre ou d'un alliage de cuivre pour une lingotière de coulée continue, ledit procédé consistant à former un tube d'ébauche sur un mandrin correspondant à la forme intérieure de la lingotière par l'application d'une force à partir de l'extérieur et à retirer le mandrin du tube de lingotière (1, 1a) après l'opération de formage. L'application de la force est réalisée par un mouvement relatif du tube d'ébauche en direction d'une matrice entourant le tube d'ébauche, la matrice présentant une structure de mise à la forme pour produire un profilage à froid (6, 6a ; 7, 7a) sur la face extérieure (5) du tube de lingotière (1, 1a), de sorte que le profilage à froid (6, 6a ; 7, 7a) est produit au moyen de la matrice lors du formage du tube d'ébauche sur le mandrin.
