Definitions
- the invention relates to a strand guide, in particular for a continuous steel slab caster, with a number of segments supporting a strand on two opposite sides with support elements, wherein the support elements for guiding the strand in a conveying direction in at least one lower frame and at least one upper Frame are arranged and wherein the frames are arranged on at least one central spar.
- a strand guide of this type is known for example from DE 198 24 366 A1.
- the strand guide has a number of support segments which form a pouring arc having opposed rows of guide and drive rollers.
- the rollers are stored in an upper and a lower frame.
- the frames are arranged on a central spar (or side frame).
- the segments can often be removed only by moving the segment upper frame to a design format.
- This format is usually smaller than the largest format to be cast. Due to malfunction when pouring the largest format can therefore encounter considerable difficulties in the expansion of the segment.
- the invention is therefore based on the object, a strand guide of the type mentioned in such a way that even with very small casting radii removal and installation of a segment or part thereof in an improved manner is possible.
- the solution of this object by the invention is characterized in that means are provided with which the at least one upper and / or the at least one lower frame can be adjusted relative to the at least one central spar in or against the conveying direction.
- a central spar is arranged on each side of a segment.
- the means preferably comprise at least one actuator which can move one of the frames in the conveying direction relative to the central spar.
- the actuator may be formed as a double-acting piston-cylinder unit. It can also comprise two piston-cylinder units, which are arranged on the central spar.
- the actuator can be designed as a hydraulic piston-cylinder system, as a pneumatic piston-cylinder system or as a mechanicalLinknverstell- element. In the latter case, the actuator may comprise a threaded spindle system driven by an electric motor.
- the support elements are advantageously designed as driven or non-driven rollers which are rotatably mounted in the frame.
- the segments preferably form a pouring arc. However, they can also be used for the vertical or horizontal area of the strand guide.
- Below a central spar is also generally a segment subframe constellation UIMiUi I -.u VCI 3LCI ICM, uic -.Ui v / uci i ⁇ i Ii ici ii ui ⁇ y ⁇ uoyouuuci ioi.
- ⁇ _o also be executed several side frame spars per segment on one side.
- the upper frame of the neighboring segments can be moved by means of the aforementioned adjusting means for the removal of a segment so that the problem-free, d. H. the collision-free removal of the segment is made possible.
- a Strangg cordsegment along its segment axis, d. H. perpendicular to the fixed side be added past without collision on the neighboring segments.
- FIG. 1 shows schematically the pouring arc of a strand guide of a continuous casting machine in side view
- FIG. 2 shows three adjacent segments of the casting arc in a possible working position
- FIG. 3 the three segments of FIG. 2 in a disassembly position for one of the segments.
- Fig. 1 the pouring arc of a strand guide 1 of a continuous casting machine can be seen.
- Each segment 2 has as essential components two frames 8 and 9, namely a sub-frame 8 and an upper frame 9, are mounted in the support elements 6, 7 in the form of rollers.
- the rollers 6, 7 can be driven or not driven, with a frame 8, 9 can have roles of both types. This defines a path in the conveying direction F for the cast strand.
- FIG. 2 The structure of a segment 2 according to an embodiment of the invention is shown in FIG. 2.
- the segments forming a casting arc are designated 2 ', 2 ", 2'” and 2 "" (in FIG. 3).
- the segments 2 used are those with a central spar guide.
- Each segment 2 ', 2 ", 2'” has a central spar 10, on whose T-shaped base part (not shown in detail in FIGS. 2 and 3) subframe 8 is fixed, which carries supporting elements in the form of rollers 6 , which support one side 4 of the strand 3.
- an upper frame 9 is arranged on the central spar 10, which likewise carries supporting elements in the form of rollers 7, which guide the side 5 of the strand 3.
- the means 11 have an actuator 12, in the present case of two Piston-cylinder units consists, with which the upper frame 9 relative to iviiLLdi IUM 1 1 ⁇ ui ui uci i IUI ILUi IU, u uud uy id nycy ⁇ i ⁇ uui o ⁇ iu ⁇ i ⁇ vci o ⁇ i ⁇ can be.
- a suitable sliding guide is provided, which allows a stable displacement movement of the upper frame 9 relative to the central spar 10 by means of the actuator 12.
- the upper frame 9 of the middle illustrated segment 2 is moved relative to the central spar 10 by the actuator 12 against the conveying direction F. Accordingly, moves the central axis 15 of the upper frame 9 away from the center axis 18 of the central spar 10.
- Fig. 3 it can be seen that the upper frame 9 has been displaced from the central spar 10 by the displacement x by the actuator 12.
- a mounting clearance 16 is in the range
- the segment 2 '"shown on the right in FIG. 3 can now be lifted out of the strand guide in the direction of the center of the casting arc without any risk of coagulation.
- any systems can be used.
- a hydraulic piston-cylinder system is provided.
- an electrical system d. H.
- a pneumatic system is possible.
- the invention thus provides, in particular, a displacement of the upper frames of the segments by means of suitable adjusting elements perpendicular to the segment axis (parallel to the fixed side), in order to provide the installation space required for the disassembly or assembly of a segment.
- the embodiment of the actuator 12 provided in the exemplary embodiment by two actuating cylinders optionally allows the displacement of the upper frame 9 in the figure to the right or left, depending on which segment is to be removed or installed.
- a possible working position of the device is illustrated. It should be noted that an adjustment of an upper frame 9 can also be used as a possible variable setting in the casting operation, for example in order to be able to make a shift of directional points.
- the proposed invention is particularly preferred for arc segments of slab and Dünnbrammenstrangg devisanlagen used. LIST OF REFERENCE NUMBERS
