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.
  • Such a continuous casting mold which has become known from EP-A-0 149 734, consists of a lower part with parallel side walls and an upper part, the wide side walls of which extend from the lower part in a funnel-shaped manner to create a space for a pouring tube immersed in the melt to the upper edge of the mold .
  • the pouring level and the start of strand formation are in the inclined wall area.
  • the shape of the pouring area is determined by the diameter and the immersion depth of the pouring tube as well as by the required safety distance between the bottom edge of the pouring tube and the broad side walls.
  • a continuous casting mold not provided for receiving an immersion pouring tube with the shrinkage of the strand is adapted to the inclination of the mold walls, the mold walls above the point of the first solidification of the strand shell being designed parallel to one another.
  • the object of the invention is to provide a continuous casting mold of the above type with a low strand shell load directly below the casting level.
  • the object is achieved in that that the broad side walls in the pouring area each consist of a first section which run essentially parallel to each other and each have a subsequent section reducing the thickness of the casting format, and the first sections extend below the level of the casting level to be set during casting operation in the area of the first strand shell formation.
  • the inventor first recognized that the shape of the entire pouring area does not necessarily have to depend on the diameter and immersion depth of the pouring tube, but rather can be freely designed to a certain extent above the pouring level.
  • the parallel course of the broad side walls according to the invention in the area of the casting mirror results in a deformation-free guidance of the still thin strand shell immediately below the casting mirror.
  • the broad side walls in the first section can deviate slightly from the parallelism and have a slight inclination to one another in order to generate compressive stresses in the strand shell in the casting direction.
  • the first sections of the broad side walls advantageously have a length of 150-350 mm measured in the casting direction.
  • first sections of the broad side walls are followed by flat and / or curved second sections without a step.
  • 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.
  • these are provided with channels 5, to which coolant supply and discharge lines 6, 7 are assigned.
  • 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 a funnel-shaped pouring area 9 into the center thereof, into which a pouring tube 10 which introduces the liquid steel projects.
  • Each broad side wall 1, 2 has three sections of different contours on its inside. The first sections a, a 'run essentially parallel to one another. In these sections, solidification takes place from the casting level 11, wherein bending stress on the still thin strand shell is avoided.
  • section b is represented by an inclined straight line and section b 'by an arc, which illustrates the possible shapes in the form of flat or curved surfaces or combinations thereof.
