Definitions

  • the invention relates to a process for the production of slabs, in particular made of steel in different formats, in a stationary mold having a wide and narrow side walls in a continuous casting installation, in which, in order to change the format, the contact pressure on the corresponding mold side walls is reduced and at least one of the mold walls is more appropriate Contact force is moved into the desired position and a corresponding device for performing the method
  • a disadvantage of the known solutions is that in the first case the slab thickness does not increase or decrease and in the second case that the adjustment of the slab thickness can only be carried out with a simultaneous change in the slab width, ie that with a thickness adjustment inevitably narrower or wider slabs are formed.
  • the invention has set itself the goal of enabling a method and a corresponding device for producing slabs not only in any width, but also in any thickness.
  • the invention achieves this goal by the characterizing features of the method claim 1 and the device claim 3.
  • the distances between the narrow side walls and thus the width of the slab and / or the distances between the broad side walls and thus the thickness of the slab can be changed as desired.
  • the format is set so that the load on the strand shell is optimized between two format changes in that the
  • Scope in the respective height of the mold is kept approximately constant.
  • the continuous casting mold required to carry out the method is composed of two broad side walls and two narrow side walls, the narrow side walls being assembled from wedge-shaped parts.
  • the narrow side walls consist of at least two wedge-shaped strips, the outer contact surfaces of which lean against the inner wall of the broad sides and the mutually facing contact surfaces are guided over the entire length of the individual parts.
  • the mutually facing contact surfaces are guided in a plane which has essentially the same direction as the corresponding broad side surfaces and which face each other at an angle of rotation of ⁇ between 0 and 30 °.
  • the angle setting deviating from 0 ° supports the pressing of the narrow side 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 chosen between 3 and 6 °. This angular range proves sufficient to be more appropriate vertical adjustment of part of the narrow sides to set the desired thickness of the slab
  • the narrow sides adjustable according to the invention for different slab thicknesses can be used not only with broad sides which are arranged parallel to the wall in the narrow side adjustment region, but also with broad sides associated with one another in the narrow side adjustment region in a wedge shape.
  • a cone angle ⁇ of 0.2 ° to 2.5 is used here ° provided
  • the adjustable narrow sides according to the invention can be used not only for vertical stationary molds, but also for molds of a continuous sheet caster.
  • the wedge-shaped parts on their mutually facing surfaces follow a constant radius, the center of which is different from that of the individual broadside radii in the paired adjustment movement mmde -
  • At least one of the respective narrow side parts are moved on an arc that follows the radius of the adjusted broad side
  • three parts are used for each narrow side, the middle wedge being configured symmetrically.
  • the contact surfaces of the individual side parts can be arranged parallel to the broad side surfaces or also conically to them.
  • Figure 1 is a plan view
  • Figure 2 front view of a straight mold Figure 3 and 4 individual side panels and Figure 5 is a side view of a mold of a sheet caster
  • FIG. 1 shows a wide side 21 of a mold 10 with the pouring area 24 and adjustment areas 23 provided at both ends.
  • Narrow sides 31 and 32 are arranged in these adjustment areas 23, which can be moved transversely to the strand-feeding direction S by horizontal adjustments 36 and parallel to by vertical adjustments 37 and 38 Strand direction S are movable Between the vertical adjustment 38 and the narrow side 32, a coupling 39 is arranged.
  • 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.
  • only one width wall is designed to be movable, with horizontal adjustments 25, 26 being provided on the broad side 21.
  • the slab mold cavity 11 is enveloped by the broad sides 21 and 22 and the narrow sides 31 and 32 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 can be moved in the area of the broad inside surfaces 51 and 52 transversely to the strand-feeding direction by horizontal adjustments 36.
  • the one provided with both sides of the pouring area 24 Adjustment area 23 is flat in the direction of strand feeding direction S
  • the transition from the adjustment area to the pouring area is shown relatively abruptly in the left area via an edge designed as a radius.
  • the pouring area has a turning point at its edges W on which merges into a circular arc, which merges tangentially into the straight line adjustment region 23
  • Figure 3 shows a sketch of the structure of the narrow side 31, namely in the upper part of the image a to c in the side view and Figure 4 a-c in section
  • the narrow side 31 is composed of the wedge-shaped parts 33 and 34 with position a.
  • the contact surfaces 41 and 42 are arranged at a wedge angle ⁇ with respect to the outer contact surfaces 45
  • FIG. 4 shows the section AA with the broad side parts 21 and 22, between which the wedge-shaped parts 33 and 34 are clamped.
  • Chen 45 are based on the inner wall in the adjustment area 23 of the broad side 21.
  • the facing contact surfaces 41, 42 are located in a plane E, which are arranged at an angle of rotation ⁇ to a plane located between opposite adjustment surfaces of the broad sides 21 and 22.
  • FIG. 3 show a narrow side 31 constructed from a total of three wedge-shaped parts 33 to 35.
  • the tip of the middle part 35 can point both upwards and downwards.
  • the mutually facing contact surfaces 33 and 44 can be arranged parallel to one another or, as shown in section BB, have an angle of rotation ⁇ which gives the wedge-shaped part 35 a conical shape in the horizontal direction.
  • FIG. 4 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 tongue 79 projects.
  • FIG. 5 shows broad sides 61, 62 of a continuous sheet casting mold with the radii Ri 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, the contact surfaces 91, 85 and 92, 86 touching each other.
  • the contact surfaces 81 and 82 facing one have a radius R m .
  • Radii R and R a usually do not have the same center point Mj or M a from which the center point of the radius R m , namely M m, is significantly different.
