Definitions

  • the invention relates to an assembly for a plant for casting and / or bending a metal strand, in particular a Bogeng manstrom, which comprises segment carrier of a support frame and corresponding segments with a roller assembly. Furthermore, the invention comprises a corresponding system.
  • support frame constructions for continuous casting plants are known from the prior art, which are usually connected to a foundation. Furthermore, several segments are installed on these support frames or support frame parts, which in turn comprise a plurality of rollers or roller pairs between which a strand is passed. As a rule, the support frame consists of two to four support frame parts or segment supports, several segments being mounted on each part of the support frame.
  • the layout DE 24 57 302 shows, for example, such a casting plant, which schematically in FIG. 1 is shown.
  • This Bogeng imaginestrom 1 ' has a support frame 2', which is formed in two parts in the region of the bend, wherein on each of the two Tragrahmenmaschine 3 'each three to four segments 4' or support segments 4 'together with rollers 5' are arranged.
  • a disadvantage of such an arrangement is that during operation of the system, the so-called "pass line" between the last seen in the casting direction last segment 4 'of the first support frame part 3' and the first segment 4 'in the casting direction Tragrahmenteils 3 'may result in a jump due to bending under the load and thermal expansion. This leads to a poorer quality of the cast and bent strand. To counteract this, although a significantly greater cost of materials could be operated in order to carry out the segment carrier correspondingly strong, but this is uneconomical. At best, time-consuming and complicated adjustments are necessary.
  • the support frame is formed, for example, in two parts and the two adjacent parts of the support frame are connected by a segment, for example by attaching a segment with a bolt connection both to the first support frame part is and is connected to other bolts with the adjacent support frame part, whereby the segment forms a bridge element or segment between the two parts of the support frame. Jumping changes in the "pass line" can thus often be avoided.
  • a disadvantage of this embodiment is that the support frame can expand undefined under the influence of heat.
  • the known fixed / floating bearing principle is repealed by such a construction.
  • the Laid-open specification DE 25 24 675 A discloses a continuous casting plant in which lower support rolls for guiding and supporting a metal strand on fixed bearing blocks and upper support rolls are mounted in movable support blocks.
  • the support blocks can be lifted off the slab with the aid of hydraulic cylinders.
  • the inventive system overcomes several disadvantages of the prior art.
  • the proposed module The segment carriers or support frame modules are even easier to carry out, since the stiffness of a single segment now also contributes to the overall rigidity or strength of the segment carriers in the casting direction.
  • the stiffness or the inherent rigidity of the segments could not contribute to the stability or rigidity of the segment carrier in the casting direction.
  • the pass line can be maintained with the solution according to the invention, since the segment carriers seen in the casting direction can be formed comparatively short by carrying only one segment; this virtually eliminates the bending of the segment carriers and their influence on the pass line.
  • segment carriers according to the invention are easier to adjust due to their smaller size.
  • the segment carriers can be adapted particularly easily to different casting radii or used for systems with different casting radii. Possibly desired adjustments are facilitated.
  • At least one of the segment carriers comprises at least four support points for connection to one of the segments.
  • a first support points for fixed storage, a second support point to a displaceable mounting transversely to the casting direction and the remaining support points are formed to a displaceable mounting in all directions.
  • all directions in particular in all directions, which lie in a plane which is spanned by the casting direction and the direction transverse to the casting direction.
  • segment carriers seen in the casting direction have substantially the same length as the respective segments carried by them. Substantially equal length of segment carrier and segment increases the rigidity of the system of these two elements.
  • At least two, preferably at least three, segment carriers are formed equivalently.
  • This modularization also increases the variability of a system designed from such segment carriers or assemblies.
  • the same parts can be used for repair, whereby the number of stored spare parts can be reduced.
  • FIG. 1 schematically shown frame parts at first glance, but they are constructed differently in reality.
  • the in FIG. 1 shown bent frame parts are not used in a vertical or horizontal section of a casting or bending plant.
  • supporting frame parts having a different shape, in particular a different curvature are necessary, so that many different types of supporting frame parts are present within a plant according to the prior art.
  • each segment carrier viewed in the casting direction, is supported at only one point on the foundation.
  • At least one of the segment carriers is essentially formed by two longitudinal members which extend preferably extend on both sides of the strand in the casting direction and which are transverse to the casting direction, preferably by cross-struts, interconnected.
  • Such a construction has both a high rigidity and a relatively low weight.
  • each of the longitudinal beams comprises at one of its ends in the casting direction a connecting means and at its other end a region whose shape is substantially complementary to that of the connecting means, so that two successively arranged in the casting direction segment carrier by means of a Connection means of a first segment carrier can be connected to the complementary region of a second segment carrier.
  • the connecting means is formed by a clevis. This connection means allows a particularly simple and secure connection of adjacent segment carrier.
  • this is designed such that the metal strand can be bent from a substantially vertical position into a substantially horizontal position.
  • the system according to this embodiment comprises between five and nine juxtaposed and interconnected segment carrier for bending the strand in the horizontal position.
  • FIG. 2 shows a support frame 2, which is connectable in points 11 with a foundation.
  • the support frame 2 consists of several segment carriers 3.
  • the segments which are supported by the segment carrier 3 are in the FIG. 2 not shown.
  • the segments or support segments are formed as usual and to those skilled in the art, for example, substantially as the segments 4 'of FIG. 1 , The exact shape of the segments and the arrangement of the rollers within the segments are not in the focus of the invention.
  • one segment can be connected to a segment carrier 3.
  • a segment is in each case supported by a segment carrier 3.
  • the segments are preferably fastened by bolts 12 to the individual segment carriers 3.
  • the invention includes not only an entire system, but individual modules can each be combined consisting of segment carriers 3 or modules 3 and a segment to a support frame 2 a plant. It is also possible that existing systems are extended by such assemblies or that existing support frame parts are replaced by an assembly. It is possible in particular, the complete To design plant only with three or two types of carrier segment. By equivalent types of carrier segments or modules, the elements can also be used subsequently for other casting radii, which is not possible with larger, specific frame parts. According to the invention, between five and nine segment carriers 3 are preferably used for the deflection of a strand from the vertical direction into the horizontal direction. In the horizontal part of the system further segment carrier 3 may be arranged.
  • FIG. 3 shows by way of example the detailed structure of a segment carrier 3.
  • a segment carrier 3 is formed by two longitudinal members 6, which extend in the casting direction. These longitudinal members 6 are preferably rigidly connected by connecting elements 7, in particular by struts, transversely to the casting direction.
  • the segment carrier 3 comprises the FIG. 3 four support points 10 on which a segment can be worn and stored together with its roller assembly. By bolt 12, the segment can be connected to the segment carrier 3 and secured on this.
  • a first support point 10 is preferably designed for fixed storage
  • a second support point 10 is formed to a displaceable transversely to the casting direction storage and formed the remaining support points to a displaceable in all directions storage.
  • the segment carrier 3 in the casting direction is preferably of the same length as the segment to be supported.
  • segment carrier 3 and the respective segment are connected to each other substantially at their corners.
  • the segment carrier 3 preferably comprises a clevis 8 for connection to an adjacent segment carrier 3.
  • the segment carrier 3 comprises at an opposite end a region 9 which is substantially complementary to the clevis 8 and with a clevis 8 of an adjacent carrier segment 3 is connectable. Instead of the clevis 8 but other forms of connecting means 8 are conceivable.
  • the segment carrier 3 is preferably fixed but rotatable with connected to the foundation. This type of storage is shown by the foundation bearing 11. At this point it should be made clear that the individual in the FIG. 3 shown features may not be construed as limiting, but merely represent an example of the formation of a segment carrier 3 according to the invention.
