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 limited to only part of the mold height and which is reduced to the narrow sides and in the casting direction to the format of the cast strip and the broad side walls run to the side of the funnel-shaped pouring area, at a distance corresponding to the strip thickness, parallel to the respective narrow side wall, forming a parallel area starting from the pouring area.
  • the broad side walls form a funnel-shaped pouring area, which is reduced to the format of the cast strip in relation to the narrow side walls and in the casting direction by means of triangular transition surfaces.
  • the broad side walls run parallel to the respective narrow side wall at a distance corresponding to the strip thickness (DE-A-34 00 220).
  • the strand shell that forms within the pouring area is subject to a beige stress when edges are reduced from the funnel-shaped pouring area to the strip format by edges running at an acute angle to the pouring direction. To limit this stress, the forming angles are kept small in the known mold.
  • the object of the invention is to provide a breakthrough-resistant mold for casting steel strips, in which the reduction of the strand shell to the strip format for reducing strand shell stress, mold wear and the required pull-out force and for improving the melt distribution to the sides is more favorable.
  • the pouring area of the mold has square transition surfaces which merge along a vertical line into the lateral parallel region and along a horizontal line into the lower sections of the mold which determine the format.
  • the contour of the transition surfaces is formed by straight lines extending from the upper edge of the mold to the lower parallel region, which in their entirety result in the shape of the transition surfaces.
  • two opposite wide side walls 1, 2 and two narrow side walls 3, 4 arranged between parallel side regions of the wide side walls 1, 4 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.
  • the broad side walls 1, 2 form an enlarged pouring area 9 in the middle thereof, into which a pouring pipe 10 which introduces the liquid steel projects during casting.
  • the strand shell 11 (FIG . 5) which solidifies in the pouring region 9 is brought to the strip format when it is lowered.
  • the lateral parts of the pouring area are designed as square transition surfaces 12 with the corner points A, B, C, D. The transition to the format-defining lower sections of the broad side walls takes place on the horizontal lines CD.
  • the contour of the transition surfaces 12 is formed by straight lines g which connect the points of the lines A-B and C-D lying one above the other and which depend on the position in one of e.g. 10 ° to 0 ° decreasing forming angle a (Fig. 5) to the format-determining lower part of the wide side walls 1, 2 are.
  • the opening angles (3 (FIG. 4)) of the pouring area decrease continuously in the casting direction and reach the value 0 on the line C-D.
  • the upper edge of the pouring area is partially curved in accordance with FIG. 4.
  • the quadrangular, transition surfaces 12 merge into the format-forming lower surfaces of the broad side walls 1, 2.
