Definitions

  • the invention relates to a method for producing slabs, in particular from Steel in different formats in a wide and narrow side walls stationary mold of a continuous caster, when changing the format the contact pressure on the corresponding mold side walls is reduced and at least one of the mold walls with the appropriate contact pressure in the desired position is moved and a corresponding device for performing the method.
  • a plate mold for the continuous casting of steel is known from DE-OS 27 02 976, in which the narrow sides by means of a clamping device between the broad side walls can be clamped. In the adjustment area of the narrow side walls of this device the broad side walls are arranged parallel to one another. A change in Distance of the broad side walls and thus a change in format of the slab with the installed side walls is not possible with this.
  • a disadvantage of the known solutions is that the slab thickness is not in the first case enlarged or reduced and in the second case that the adjustment of the slab thickness can only be carried out if the slab width is changed at the same time, i.e. that with a thickness adjustment inevitably narrower or wider slabs arise.
  • the invention has set itself the goal of Process and a corresponding device for the production of slabs not only in any width, but also in any thickness.
  • the invention achieves this goal by the features of the method claim 1 and the device claim 3.
  • the distances of the slab to change the format Narrow side walls and thus the width of the slab and / or the spacing of the Broad side walls and thus the thickness of the slab can be changed as desired.
  • the format is set so that between two Format changes, the load on the strand shell is optimized in that the Scope in the respective height of the mold is kept approximately constant.
  • the continuous casting mold required to carry out the process is in each case put together two broad sides and two narrow side walls, the Narrow side walls can be assembled from wedge-shaped parts.
  • the narrow side walls consist of at least two wedge-shaped strips, the outer Contact surfaces lean against the inner wall of the broad sides and their each other facing contact surfaces over the entire length of the individual parts is.
  • the mutually facing contact surfaces are guided in one plane, the have substantially the same direction as the corresponding broad side surfaces and facing each other at an angle of rotation of ⁇ between 0 and 30 ° are.
  • the angle setting deviating from 0 ° supports the pressing of the Narrow sides to the broad side walls.
  • a groove and a tongue are provided at this point.
  • the wedge angle ⁇ of the side surface parts is preferably between 3 and 6 ° selected. This angular range proves sufficient to be more appropriate vertical adjustment of part of the narrow sides ensures the desired thickness of the slab adjust.
  • the narrow sides according to the invention which are adjustable for different slab thicknesses are not only usable on broad sides that are parallel-walled in the narrow side adjustment area are arranged, but also with wedge-shaped associated broad sides in Schmalcetverstell Siemens.
  • a cone angle ⁇ is used here from 0.2 ° to 2.5 °.
  • the adjustable narrow sides according to the invention are not only for vertical ones stationary molds, but can also be used for molds in a continuous caster. at this configuration is followed by the wedge-shaped parts on their mutually facing surfaces a constant radius, the center of which is different from that of the individual Broadside radii. With the pairwise adjustment movement at least one of the respective Narrow side parts are moved on an arc that corresponds to the radius of the adjusted broadside follows.
  • the middle wedge is symmetrical.
  • the contact surfaces of the individual side parts parallel to the broad side surfaces or also conical to these be arranged.
  • FIG. 1 shows a broad side 21 of the mold 10 with the pouring area 24 and Adjustment areas 23 provided at both ends.
  • these adjustment areas 23 are narrow sides 31 and 32 arranged transversely by horizontal adjustments 36 movable to the strand conveying direction S and parallel by vertical adjustments 37 and 38 are movable to the strand conveying direction S.
  • the Vertical adjustment 38 is arranged in the axial direction of the narrow side 32, in the left part the vertical adjustment 37 is provided parallel to the main axis of the narrow side 31.
  • FIG. 2 shows the top view of the mold.
  • the slab mold cavity 11 is enveloped by the Broad sides 21 and 22 and the narrow sides 31 and 32.
  • These narrow sides 31, 32 are composed of a first wedge-shaped part 33 and a second wedge-shaped Part 34.
  • the individual wedge-shaped parts 33 and 34 are in the region of the broad inside surfaces 51 and 52 transversely to the strand conveying direction by horizontal adjustments 36 movable.
  • the one provided with both sides of the pouring area 24 Adjustment area 23 is flat in the direction of strand conveyance S.
  • the representation in the left area is the transition from the adjustment area to the pouring area. area shown relatively abruptly over an edge formed as a radius.
  • the pouring area has a turning point W at its edges, which merges into a circular arc, which is tangential T in the straight line adjustment range 23 passes.
  • Figure 3 shows a sketch of the structure of the narrow side 31, namely in the upper part of the Figures a to c in side view and Figure 4 a-c in section.
  • the narrow side 31 is composed of the wedge-shaped parts 33 and 34.
  • the contact surfaces 41 and 42 are to the outer contact surfaces 45 arranged at a wedge angle ⁇ .
  • the section AA is shown with the broad side parts 21 and 22, between the wedge-shaped parts 33 and 34 are clamped.
  • the outer contact surfaces 45 lean against the inner wall in the adjustment area 23 on the broad side 21 on.
  • the facing contact surfaces 41, 42 are located in a plane E that at an angle of rotation ⁇ to one between opposite adjustment surfaces of the Broad sides 21 and 22 located level are arranged.
  • the mutually facing contact surfaces 43 and 44 can be parallel to each other be arranged or as shown in section BB, one Have angle of rotation ⁇ , the one of the wedge-shaped part 35 in the horizontal direction conical shape there.
  • FIG. 4 also shows an embodiment of the facing contact surfaces 41, 42 of the wedge-shaped parts 33, 34 and 71, 72, in which a groove 78 is provided into which a spring 79 projects.
  • FIG. 5 shows broad sides 61, 62 of a continuous sheet casting mold with the radii R i and R a .
  • the inner broad side 61 is adjustable by a horizontal adjustment 36.
  • Narrow side parts 71 and 72 are clamped between the broad sides 61 and 62, wherein the contact surfaces 91, 85 and 92, 86 touch each other.
  • the contact surfaces 81 and 82 facing one have a radius R m .
  • the radii R i and R a usually do not have the same center M i or M a, from which the center of the radius R m , namely M m, is significantly different.
