  • the object with respect to the method is achieved with the features of claim 5.
  • adjusting elements are provided for connecting a roller bridge to a mainland and for adjusting the position of the at least one roller bridge, wherein the adjusting element is articulated on the roller bridge away from the joint.
  • roller bridges of the two molds are connected directly after ordered segments or two successively arranged segments by means of a joint relative to each other displaceable, with an adjustment between this joint and a mainland is arranged and continue the first roller bridge and the second roller bridge is assigned in each case a further adjustment element, which is arranged between the joint facing away from the end of the roller bridge and a mainland.
  • roller bridges of the three of the mold immediately after ordered segments or three consecutive segments are each pairwise displaceable relative to each other by means of a joint, wherein an adjustment between the respective joint and a mainland is arranged and further the first roller bridge and the third roller bridge is assigned in each case a further adjusting element, which is arranged between the end of the roller bridge facing away from the joint and a mainland.
  • FIG. 1 shows a schematic representation of a continuous casting plant 1 according to the prior art.
  • a strand guiding device 3 is provided, which is divided into two segments 4. outgoing from the mold 2, a cast strand in the continuous casting 1 in the direction of arrow 5 through the strand guide segments 4 of the strand guiding device 3 is performed.
  • each of the segments 3 comprises a first roller bridge 6-1 arranged on one side of the cast strand and a second roller bridge 6-2 arranged on the other opposite side of the cast strand.
  • the roller bridges 6-1 and 6-2 in this case have at least one roller or roller arrangements 7-1 and 7-2, between which the cast strand is supported and guided.
  • each roller bridge 6-1 has two adjustment elements 8, by means of which the roller bridges 6-1, which are each separated from one another and are independently adjustable, are adjustable.
  • FIG. 2 shows a schematic representation of a continuous casting 11 according to the invention.
  • a strand guiding device 13 is provided, which is divided into three segments 14-1, 14-2 and 14-3.
  • the cast strand not shown, is guided in the continuous casting 11 in the direction of arrow 15 through the strand guide segments 14-1,14-2 and 14-3 of the strand guiding device 13.
  • each of the segments 13 comprises a first roller bridge 16-1, which are arranged on one side of the casting strand and a second roller bridge 16-2, which are arranged on the other opposite side of the casting strand.
  • the roller bridges 16-1 and 16-2 in this case have rollers or roller assemblies 17-1 and 17-2, between which the strand is guided.
  • a fixed arrangement of Rollers 17-2 provided on one side with the roller bridges 16-2, which is also referred to as the fixed side.
  • roller bridges 16-1 of the segments 14-1 with the rollers 17-1 are in turn displaced.
  • the roller bridges 16-1 on the lot side by means of adjusting elements 18 are adjustable in order to set the angle of the roller bridges 16-1 relative to the roller bridges 16-2 or against the neutral phase at an angle can.
  • FIG. 2 The roller bridges 16-1 arranged downstream of the mold have an adjustment element 18, which is articulated to the roller bridges 16-1.
  • a hinge 20 is further provided between the roller bridges 16-1, which holds the two roller bridges 16-1 displaceable relative to each other.
  • a third adjustment element 19 is provided according to the invention, which is articulated between the two roller bridges in the region of the joint 20.
  • two roller bridges 16-1 can be designed to be displaceable with only three adjustment elements 18, 19.
  • a further segment with a further roller bridge pair 16-1, 16-2 is provided in the continuous casting direction, the roller bridge 16-1 being adjustable with two adjusting elements 18.
  • FIG. 3 shows a schematic representation of another embodiment of a continuous casting plant according to the invention 21.
  • a strand guiding device 23 is provided, which is divided into four segments 24-1, 24-2, 24-3 and 24-4.
  • the casting strand is guided in the continuous casting installation 21 in the direction of the arrow 25 through the strand guide segments 24 - 1, 24 - 2, 24 - 3 and 24 - 4 of the strand guiding device 23.
