Definitions

  • the invention relates to a mold for the continuous casting of steel strip, with cooled broad side walls and narrow side walls, the wide side walls forming a funnel-shaped pouring area, which is reduced to the narrow sides and in the casting direction to the format of the cast strip.
  • the invention is based on the finding that, in the known mold shape, the strand shell solidifies in a trapezoidal manner in the region of the narrow side walls. As a result of the mold narrowing, this leads to the strand becoming jammed.
  • the broad side walls run parallel to the respective narrow side wall at a distance corresponding to the strip thickness, to the side of the funnel-shaped pouring area.
  • the width can also be changed by adjusting the narrow side walls during casting.
  • the width of the parallel region of the broad side walls advantageously corresponds at least to the thickness of the casting belt.
  • the strand shell is subjected to a bending stress which is proportional to the forming angles ⁇ of the broad side walls measured in the horizontal or vertical direction.
  • the pouring area is designed in accordance with a further feature of the invention in such a way that the forming angles ⁇ are less than 10 °.
  • the pouring area can be designed in whole or in part in an arc shape.
  • a special lubrication can be assigned to the broad side walls in the parallel area.
  • the mold walls can have lower thermal conductivity and greater heat resistance in the upper area than in the lower area.
  • the mold walls can also consist of a material with a thermal conductivity of at most 50% of that of the mold copper.
  • the narrow side walls can be adjustable to change the format width in the parallel area of the wide side walls.
  • the mold is assigned an oscillation drive and an oscillation guide.
  • the cooling speed and the take-off speed are dimensioned such that the strand shell is thinner than 6 mm at the end of the funnel-shaped pouring area, the take-off speed being at least 3 m / min, preferably 4-6 m / min is.
  • two opposite broad side walls 1, 2 and two narrow side walls 3, 4 arranged between parallel side regions of the wide side walls 1, 2 form the molding space.
  • the narrow side walls 3, 4, which are also cooled, can be adjusted by means of spindles 8 between the wide side walls 1, 2.
  • An oscillation device is indicated by arrows 13.
  • the broad side walls 1, 2 form a funnel-shaped pouring region 9 into the center thereof, into which a pouring tube 10, which introduces the liquid steel 11, projects.
  • the mold space according to the invention which can be seen in FIG. 1, causes the strand shell 12 to solidify at the strip side edges, as can be seen in FIG. 5, in which the disadvantages of a trapezoidal solidifying strand shell 12 'shown in FIG. 4 are avoided.
  • the pouring area is reduced to the thickness d of the cast strip.
  • the strand shell 12 which solidifies in the pouring area, is deformed when it is conveyed out when it is reduced to the strip thickness d. In order to keep the resulting bending strains of the strand shell 12 low. all angles oC of the pouring area that are decisive for the deformations are less than 10 °.
