Definitions

  • the invention relates to a mold for the vertical continuous casting of steel strip, with cooled broad side walls and narrow side walls, the wide side walls forming an enlarged pouring area which is limited to only a part of the mold height, 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 pouring area at a distance approximately corresponding to the strip thickness up to the respective narrow side wall.
  • the object of the invention is to provide a continuous casting mold of the type mentioned above, in which a steel strip is produced with a surface which is uniformly flawless over the range. In particular, the friction between the mold wall and the solidifying strand shell is to be reduced.
  • the pouring slag covering the casting level can flow better between the mold wall and the strand shell, as a result of which the friction is reduced.
  • steel strips can be cast with a surface that is uniformly flawless over the entire width of the strand, since the formation of oscillation marks and thus the risk of transverse cracks forming in the base of the oscillation marks are avoided.
  • the upper sections C, C 'advantageously extend to a depth t 20 to 60 mm below the target bath level.
  • two opposite broad side walls 1, 2 and two narrow side walls 3, 4 arranged between side regions of the wide side walls 1, 2 form the molding space.
  • the narrow side walls 3, 4 are adjustable by means of spindles 5 between the side areas of the wide side walls 1, 2.
  • the broad side walls 1, 2 form an enlarged pouring area 6 into the center thereof, into which a pouring tube 7 which introduces the liquid steel projects.
  • the pouring area 6 is reduced in the casting direction and towards the narrow side walls 3, 4 to the format of the strip to be cast.
  • Liquid steel is passed through the pouring tube 7 up to the nominal bath level 8 into the mold.
  • the mold level is covered by casting powder that melts into pouring slag.
  • a strand shell forms on the cooled broad side walls 1, 2 and narrow side walls 3, 4.
  • the strand shell forming in the pouring area 6 is reduced to the belt format when it is lowered.
  • the lateral parts of the pouring area 6 are designed as rectangular transition surfaces 9. The transition to the format-determining lower parts A of the broad side walls 1, 2 takes place on horizontally running curves 10.
  • the broad side walls 1, 2 consist of lower, parallel sections B, B 'and upper, the target bath level 8 overlapping sections C, C'.
  • the width of the narrow side wall 4 is adapted to the contour of the wide side wall 1, 2 in the region of sections C, C '.
