Definitions

  • the invention relates to a continuous casting mold for casting thin slabs with cooled broad side walls and between these, arranged arranged, cooled narrow side walls, which form an upper molded part and a lower support part.
  • the cooled broad side walls and narrow side walls form the upper molded part and the support part surrounding the thin slab on all sides up to the mold exit.
  • the support part is closed at the bottom by the start-up head.
  • the desired width of the thin slab can be adjusted by adjusting the narrow side walls.
  • the known mold has the disadvantage that cracks form in the edges of the thin slabs, particularly when casting at high casting speeds. This leads to a reduction in quality in the rolled finished product.
  • the object of the invention is to provide a mold of the type specified, the formation of edge cracks in the in a simple manner without impairing the dimensional stability Thin slab is avoided. An adjustment of the narrow side wall and a seal at the lower end of the mold should be possible.
  • This formation of distance between the casting strand side and the side strips of the narrow side walls in a simple manner prevents excessive cooling of the casting strand edges on both sides and thus prevents the formation of cracks. It is possible to seal the mold by the start-up head at the lower end of the mold and to adjust the narrow side walls to change the format and to adjust the taper.
  • each narrow side wall consists of a flat upper section and a lower section with lowered side strips.
  • each narrow side wall consists of an upper section with raised side strips and a flat lower section.
  • the width of the side strips is advantageously a maximum of 15 mm.
  • the length of the outwardly offset side strips in the lower section of the narrow side wall is a maximum of 400 mm.
  • the length of the protruding side strips in the upper section of the narrow side wall is at least 400 mm.
  • a mold for casting thin slabs consists of two broad side walls 1, 2 and two on the side between the broad side walls 1, 2 adjustably arranged narrow side walls 3, 4.
  • the wide side walls 1, 2 are curved at the top and form an enlarged pouring area 5.
  • the wide side walls 1, 2 and the narrow side walls 3, 4 are provided with cooling water channels 6.
  • FIGS. 3, 5 and 7. An inventive design of the working side of the narrow side walls 3 according to FIG. 1, left side, is illustrated in FIGS. 3, 5 and 7. Thereafter, the narrow side walls 3 consist of an upper section 3a with a flat working surface 3a 'and a lower section 3b. In the lower section 3b, a middle strip 3b 'is aligned with the upper working surface 3a'. Two side strips 3b '' are recessed with respect to the central strip 3b '. Their width is advantageously less than 15 mm.
  • FIGS. 4, 6 and 8 An alternative design according to the invention of the working side of the narrow side wall 4 according to FIG. 1, right side, is illustrated in FIGS. 4, 6 and 8.
  • the narrow side walls 4 consist of an upper section 4a and a lower section 4b.
  • the upper section 4a has a central strip 4a 'and two projecting side strips 4a''.
  • the lower section 4b forms an overall flat working surface 4b 'aligned with the central strip 4a' of the upper section.
  • the strand shell 9 shown in FIG. 4 solidifies on the working surfaces 4a ′, 4a ′′ of the upper section 4a of the narrow side wall 4, with the side strips 9a behind.
