- the roller bridge next to the mold is hinged at its end closest to the mold, the other end of the roller bridge being displaced. is rerable.
- the roller bridges following this first roller bridge are connected to one another in a coupled manner and limitedly displaceable in consideration of the coupling, wherein one end of a roller bridge can always be displaced together with another end of an adjacent roller bridge.
- EP 0 545 104 B1 also discloses a device for continuous casting, wherein the device has a fixed roller set and a further second roller set which can be braced relative to this first roller set.
- the object of the invention is therefore to provide a device and a method which allow to make the strand guide and the strand more flexible.
- the strand guiding device comprises in particular at least one first adjusting element for connecting the first roller bridge to a first mainland and for individually positioning the first roller bridge with respect to the neutral phase of the cast strand and at least one second adjustment member for connecting the second roller bridge to a second mainland and for individually positioning the second roller bridge with respect to the neutral phase of the casting strand.
- the neutral phase in the interior of a cast strand which has not yet solidified describes that fictitious line which connects the hottest points in the longitudinal direction of the strand, each viewed in a cross section of the strand. It can, but does not have to coincide with the geometric mean line of the strand, especially in the case of asymmetrical cooling.
- the claimed subject matter of the invention advantageously enables the two roller bridges of a segment to be set on either side of the cast strand independently of each other with respect to the neutral phase of the cast strand.
- the reference point for the adjustment and alignment of the strand guide or the roller bridges according to the invention is no longer, as in the prior art, the roller conveyor of the fixed side, but the neutral phase of the strand.
- the individual, which is now possible due to the invention, i. independent positioning of the roller bridges on both (broad) sides of the casting strand with respect to the neutral phase of the strand or alternatively to their respective continents forms the basis for a substantial quality improvement in continuous casting, in particular in the production of slabs.
- the continuous casting is improved with the invention procedurally insofar as it allows individual support of the strand shell on the individually engageable roller conveyors, the support independent and flexible in terms of optimum solidification process, but also in terms of a desired Softreduction and / or with regard to liquid core reduction to be carried out.
- the adjusting elements are mechanically formed and allow a static adjustment of the individual position of the roller bridges with respect to the neutral phase of the casting strand by means of spacers, so-called spacers.
- the adjusting elements can also be designed as hydraulic elements. This has the advantage that then a setting or a change in the employment of the roller bridges z. B. can also be done from a remote control room during operation of the strand guiding device.
- a particularly stable positioning or adjustment of the roller bridges to the cast strand is achieved when the roller bridges are positioned with four provided in their respective corner areas adjustment elements.
- a positioning at a certain angle ⁇ > 0 to the neutral phase of the cast strand is possible.
- the respective opposite roller bridges can either be attached to the same or to each different mainland.
- the mainland is the segmental frame of the segment.
- the mainland may also be any stationary structural element of the continuous casting plant or in the vicinity of the continuous casting plant, e.g. around a wall, act.
- the above object is further achieved by a method for operating the aforementioned strand guiding device.
- the advantages of this method correspond to the advantages mentioned above with respect to the device.
- the strand guiding device according to the invention and the claimed method enable both symmetrical and asymmetrical adjustment of the roller bridges with respect to the neutral phase of the cast strand.
- the roller bridges are set symmetrically, ie at the same distance from the neutral phase of the hot strand.
- the symmetrical adjustment or employment also includes a symmetrical employment of the roller bridges on both sides of the cast strand at an angle ⁇ > 0 against the neutral phase of the cast strand explicitly with a.
- An asymmetrical adjustment of the roller bridges with respect to the neutral phase of the cast strand can be useful, in particular, during a casting operation with regard to optimum segment conicity / taper, with regard to a liquid call reduction to be carried out or with regard to soft reduction.
- the invention is a total of three figures attached, wherein
- FIG. 1 shows a continuous casting with a strand guiding device according to a first embodiment in a first variant for the employment of the roller bridges;
- Figure 2 shows the continuous casting with the strand guiding device according to a second embodiment in a second variant for the employment of the roller bridges
- Figure 3 shows the continuous casting with the strand guiding device according to the second embodiment in a third variant for the employment of the roller bridges shows.
- the strand guiding device 100 comprises two segments 110 which are arranged downstream in the continuous casting direction (arrow direction) of the mold 210.
- Each of the two segments 110 comprises a first roller bridge 114-1 on one broad side of the cast strand and a second roller bridge 114-2 on the opposite broad side of the cast strand.
- the casting strand is represented in FIGS. 1-3 by the vertical knot-dotted line.
- Each of the two roller bridges 114-1, 114-2 each includes a plurality of rollers 116-1, 116-2 for supporting and guiding the cast strand.
- the first roller bridge 114-1 is preferably variably positionable with four adjustment members 118 on a first land 112-1, i. H.
- the second roller bridge 114-2 is fastened variably positionable by means of preferably four adjustment elements on a second mainland 112-2; also of these adjusting elements only two are shown in Figure 1 and designated there by the reference numerals 118-1 and 118-2. All adjustment elements are used for individually positioning or adjusting their respective associated roller bridges with respect to the neutral phase N of the casting strand.
- the locking elements according to a first embodiment are mechanically formed. This means that the individual adjustment of the roller bridges with respect to the neutral phase of the cast strand is Dancing pieces 119 takes place, which are placed in the region of the adjusting elements between the roller bridges and the respective mainland.
- the jobs defined by the spacers settings or the roller bridges to the cast strand are not changeable due to the high temperatures that prevail during the casting operation in the vicinity of the strand guiding device during the ongoing casting operation and thus static.
- FIG. 2 differs from FIG. 1 in that the adjusting elements are designed according to a second exemplary embodiment in the form of hydraulic cylinders 118'-1 118 -4.
- this design of the adjusting elements also allows a change in the employment of the roller bridges during the ongoing casting operation. This is particularly advantageous for a preferably continuous adjustment of the employment of the bridges to a possibly caused by the cooling process Materialdickenschund the cast strand or other casting parameters such as steel quality and casting speed during the current casting operation.
- FIG. 2 in contrast to FIG. 1, an asymmetrical adjustment (second variant) of the roller bridges to the cast strand is shown; this is expressed in Figure 2 in that the left roller bridge 114-1 with their associated roles a smaller distance from the neutral phases of the cast strand than the opposite roller bridge 114-2 with their associated roles.
- FIG. 3 shows a symmetrical adjustment of the roller bridges to the neutral phase of the cast strand.
- the roller bridges 114-1 and 114-2 in FIG. 3 are not set parallel to the neutral phase, but with a two-sided angle ⁇ > 0 to the neutral phase. This applies in FIG. 3 for the segment immediately downstream of the mold; however, in the second segment downstream in the casting direction, the roller bridges 114-1, 114-2 are again arranged parallel to the neutral phase.
