Definitions
- the invention relates to a method for sealing a gap between a roller end face and a side seal of a roller band casting machine, and an apparatus for performing the method.
- the present invention is based on the object of proposing a method of the type mentioned at the outset and an apparatus for carrying out the method by means of which the risk of leakage from the liquid metal is largely eliminated and the formation of fins on the narrow side of the metal strip is avoided. According to the invention, this object is achieved by a method having the features of claim 1 and by a device according to claim 9.
- an electric vortex field is generated in the region of the gap in such a way that a gradient field is created locally and the eddy currents generated in the metal melt to be cast prevent the melt from penetrating into the gap or pushing the melt back out of the gap Sealing gap effectively supported, reliable sealing guaranteed and consequently better quality of the casting belt edges and a reduction in waste.
- a particular advantage here is the relatively small amount of energy required to generate the local swirl field.
- Figure 1 shows schematically the inventive sealing principle of a gap between a roller end face and a side seal.
- FIG. 2 schematically shows the arrangement of a number of magnetic elements arranged along the roll end faces in the mold area of a strip casting machine for generating an electrical vortex field
- FIG. 3 shows one of the magnetic elements according to FIG. 2 in cross section along line A in a first embodiment
- FIG. 4 shows one of the magnetic elements according to FIG. 2 in cross section along line A in a second embodiment
- FIG. 5 shows one of the magnetic elements according to FIG. 2 in cross section along the line A in a third embodiment.
- 1 shows a casting roll 1 of a two-roll strip casting machine for casting a metal strip, in particular a steel strip, in partial section.
- This casting roller 1 together with a second roller 2 is also indicated schematically in FIG. 2.
- a mold space for the liquid metal, which is denoted by 5 in FIG. 2 is delimited by the two casting rolls 1, 2 on the one hand and two side seals 3 arranged in the end region of the rolls 1, 2 on the other hand.
- the material of the side seals 3 is usually ceramic.
- a sealing gap 10 is present between an annular roller end face 7 of the roller 1 and the corresponding side seal 3. So that no liquid metal penetrates into this sealing gap 10 (and thus fins are formed on the narrow side of the metal strip) or even emerges from this sealing gap 10, not only is the capillary effect in this sealing gap 10 used, but additionally an electrical vortex field is generated according to the invention in such a way that A gradient field is formed locally in the area of the sealing gap 10, which is indicated schematically in FIG. 1 and is designated by 13, and which results in a force which counteracts the penetration of the liquid metal into the sealing gap 10.
- a plurality of magnetic elements 15 are arranged one after the other distributed over the corresponding roller circumference in the area of the mold space 5 or the respective sealing gap between each roller end face 7 and the relevant side seal 3.
- the magnetic elements 15 are arranged in a stationary manner and are preferably fixed to the side seals 3, so that they change together with the side seals when the roll is changed. can be removed in a simple manner by means of a manipulator (not shown in the drawing).
- the structure of individual magnetic elements 15 can be seen from FIGS. 3 to 5, although other configurations would of course also be possible in addition to these three illustrated embodiment variants.
- the individual magnetic elements 15, which are divided over the respective roller circumference from top to bottom and towards the passage gap 4, are advantageously arranged in a modular manner. They cover almost the entire length of the side seal 3, which runs along the respective casting roll 1, 2.
- the two lowermost magnetic elements 15 ', 15 "of both rollers 1, 2, which are arranged in the immediate area of the passage gap 4, are each combined into one.
- the individual, appropriately suitably designed magnetic elements 15 are preferably equipped with independently adjustable ones The independent regulation is carried out depending on the process requirements and the pressure level, preferably the magnet elements 15 which are arranged at the same height (ie at the same distance from the passage gap 4) in front of the end of both rollers 1, 2 and are opposed to one another.
- each magnetic element 15 comprises a laminated iron body 16 composed of essentially L-shaped metal sheets or produced by a sintering process, and a coil 17 associated therewith.
- the respective iron body 16 seen in the circumferential direction of the roll 1 or 2 in the coil area 16 s to half the length, and the L-shaped sheets are layered overlapping in the coil area, which results in the same cross section over the entire length in the field direction of the iron body 16 as within the coil 17 ,
- the iron body 16 is supported in its upper region 16o from the outside on the side seal 3 and fixed in a manner not shown in detail.
- a lower region 16u is connected to a front iron body region 16v, which extends upward toward the sealing gap 10.
- a field guide 20 is built into the end face 7 of the roller, which is formed by a ferromagnetic, laminated or sintered ring or by one or more ring segments ,
- An upper surface 18 of the iron body region 16v runs parallel to a surface 19 of the field guide 20 or the roller end face 7, as a result of which, for example, an obliquely running part 10 ′ of the sealing gap 10 is formed.
- Copper plates 22, 23 are preferably arranged within the iron body 16, which likewise influence the gradient formation of the electrical vortex field 13 and push the stray field in the direction of the sealing gap 10. There may be two copper plates 22, 23. These are also provided as cooling elements.
- the iron bodies 16, the side seals 3, the field guides 20 and the copper plates 22, 23 can have different cross-sectional shapes or dimensions. Suitable field guides could also be installed in side seals 3 (instead of on the roller face 7 or in addition to it).
- 5 shows that the gradient formation in the sealing gap area can be additionally optimized by changing the air gap by arranging further, additional inclined surfaces 24 or 25 on the iron body 16.
- the invention is sufficiently demonstrated with the exemplary embodiments explained above. However, it could be illustrated in further variants. For example, the number of magnetic elements 15 provided per row could be varied, ie in principle only one or more than eleven (as shown) could be provided.
- the respective gap 10 between the roller end face 7 and the side seal 3 can be formed either by mutual positioning or by a spaced arrangement of the two.
