  • the EP 1 370 380 B1 describes the strand guide of a continuous casting and a Anstell compiler for their role segments.
  • the strand guide comprises at least two segments, which are usually formed as roller segments with one strand input side and one strand output side and a pair of roller carriers with support rollers, wherein the roller carriers can be adjusted by means of hydraulic adjusting units. Between adjacent segments a mechanical connection is ever present, so that when arranging a pair of cylinders on the strand input side of a segment whose Anstellterrorism takes place both on this side and at the same time on the strand exit side of an associated precursor segment. When arranging a pair of cylinders on the strand exit side of a segment, the adjusting movement takes place both on this side and at the same time on the strand input side of an associated following segment.
  • the object of the invention is to simplify the setting of the format thickness of the cast strand within a continuous casting plant for casting metal strands, so that a flexible and rapid adjustment of different formats is ensured in successive casting processes. At the same time, the operational safety is to be improved and the costs reduced.
  • reaction forces in the present text means those forces which are exerted on the roller carriers of the strand guide segments transversely to the casting direction due to the hydrostatic pressure acting in the interior of the liquid metal strand.
  • the advantage of this arrangement according to the invention is the quick and easy connection of the mold to the first strand guide segment with simultaneous automatic adjustment of the format thickness in the first strand guide segment of the continuous casting over the first coupling point without the use position-controlled Hydraulic cylinder in the first strand guide segment would be mandatory.
  • the coupling point advantageously a simple and secure mechanical connection between the mold and the first strand guide segment is created.
  • the coupling point has the advantage that the mold can be replaced independently of the first strand guide segment. This simplifies the assembly considerably.
  • the arrangement according to the invention provides that the first coupling point is arranged between the mold and the loose side of the first strand guide segment in order to unambiguously / firmly position the loose side of the first strand guide segment to the mold.
  • the invention provides that an oscillating drive is arranged on the mold, which vibrates the mold in the casting direction.
  • the first coupling point is therefore designed so that a kokillen workede half of the first coupling point connected to the mold and a segment-side half of the first coupling point connected to the first strand guide segment are freely displaceable against each other in an engaged position in the direction of vibration.
  • the mutually displaceable kokillen workede and segment-side half also allow irregular forces in the casting direction, which arise for example during the casting during filling of the liquid casting metal, can be compensated by the coupling point.
  • the first coupling point is designed so stable that the reaction forces generated in the interior of the still liquid metal strand within the first strand guide segment are at least partially transmitted to the mold via the first coupling point.
  • this eliminates additional fasteners, such. B. hydraulic cylinder, on the first strand guide segment for connecting its Losseite with its fixed side and for receiving the reaction forces in the first strand guide segment.
  • B. hydraulic cylinder on the first strand guide segment for connecting its Losseite with its fixed side and for receiving the reaction forces in the first strand guide segment.
  • the invention provides that at least one of the mold associated connecting element is designed to be stable, that it is not only the resulting in the mold due to the prevailing ferrostatic pressure there reaction forces on the mold walls, but in addition also at least partially transmitted from the first strand guide segment reaction forces can absorb and absorb.
  • the connecting element can be arranged on the mold inlet side and / or the mold outlet side and / or between them. Since the loose side and fixed side of the mold are usually preassembled and firmly joined together by means of the connecting element, the at least one connecting element of the mold can advantageously also be used to take over at least part of the reaction forces from the first strand guide segment.
  • the invention further provides that the strand guide has a second strand guide segment, in the casting direction of the first strand guide segment downstream and connected via a second coupling point with the first strand guide segment.
  • a half of the second coupling point connected to the first strand guide segment and a half of the second coupling point connected to the second strand guide segment are freely displaceable relative to one another in the casting direction.
  • Such a design of the second coupling point allows for easy insertion and coupling of the first segment to the second strand guide segment.
  • the assembly and disassembly of the strand guide segments carried by the insertion into the coupling point independently and are therefore much faster and easier to perform.
  • Adjusting the alignment between the output cross section of the first strand guide segment and the input cross section of the second strand guide segment is omitted in the inventive arrangement, since the two halves are preset such that no further adjustment within the strand guide is necessary after connection of the strand guide segments.
  • the invention provides that the second coupling point is designed so stable that the reaction forces can be transmitted within the first strand guide segment at least partially from the second coupling point to the second strand guide segment.
  • the second strand guide segment associated third connecting element for connecting the fixed side to the loose side of the second strand guide segment is formed so stable that it is not only in the second strand guide segment Reactive forces arising but also at least partially absorb and absorb the resulting from the first strand guide segment resulting and transmitted from the second coupling point on the second strand guide segment reaction forces.
  • the third connecting element can advantageously be arranged according to the space and force relationships on the input side and / or on the output side and / or in the central region of the second strand guide segment.
  • reaction forces distributed from the first strand guide segment to the first and the second coupling point and thus to the mold and the second strand guide segment Due to this distribution of force connecting elements in the region of the first strand guide segment are basically unnecessary. As a result, the installation and removal of the first strand guide segment is significantly simplified.
  • At least one second connection element is arranged on the input side and / or the output side and / or in the central region of the first strand guide segment, for connecting the fixed side to the loose side of the first strand guide segment.
  • the second connecting element is designed so stable that it can at least partially absorb and compensate for the reaction forces arising in the first strand guide segment.
  • the second connecting element leads to an increased load capacity of the first strand guide segment, when the reaction forces in the first strand guide segment can also be partially derived in addition to the mold and / or the second strand guide segment. At rather low maximum loads in the strand guide segment can at least one of the coupling points be constructively smaller and thus designed to be weaker.
  • the invention provides that the coupling points are articulated. Advantage over a rigid connection is the possibility of improved adaptation to the strand guide, especially in the bow area of the strand guide, and an improved distribution of force in the joint.
  • the coupling points are designed decoupled. As a result, the strand guide segments can be separated quickly and easily from each other.
  • the first coupling point and / or the second coupling point are formed as a sliding bearing.
  • the connection provides only one degree of freedom in the casting direction.

  • the invention provides that between the kokillen salen half of the first coupling point and the segment-side half of the first coupling point a sliding bearing or a roller bearing is arranged.
  • a sliding bearing or a roller bearing is arranged between the kokillen salen half of the first coupling point and the segment-side half of the first coupling point.
  • the invention further provides that - when the first coupling point is in engagement - the jaw width of the strand input side of the first strand guide segment coincides with the jaw width of the output side of the mold and is aligned.
  • the format thickness of the mold is previously set outside the strand guide device by suitable positioning of the halves of the coupling points. Through the coupling point, the format thickness is automatically transferred from the mold to the first strand guide segment during coupling. An otherwise very time-consuming adjustment of the mouth widths in the transition region from the mold to the first strand guide segment is omitted here.
