Definitions

  • the invention relates to a continuous casting mold for producing thin strands in slab format, with two longitudinal walls corresponding to the longer cross-sectional sides of the strand to be cast, and two transverse walls approximately parallel to one another, at least over part of the mold height.
  • the invention has for its object to provide a continuous casting mold for the production of thin strands in slab format, in particular in the size range from 40 to 90 mm x 400 to 200 mm, which ensures minimal deformation of the continuous shell within the continuous casting mold, but still allows the use of a submerged nozzle and provides the immersion nozzle with a maximum space in the pouring area of the continuous casting mold.
  • the invention solves this problem in a continuous casting mold according to the preamble of claim 1 with the features as specified in the characterizing part of claim 1.
  • Advantageous embodiments of the continuous casting mold in the context of the present invention are specified in the subclaims.
  • the continuous casting mold 1 is followed in the casting direction by the guide frame 2 formed by rollers, to which the transport rollers 3 and a roller table 7 are connected.
  • the continuous casting mold 1 is fed from a distributor 4 via an immersion spout 5.
  • a plug 6 is used to regulate the melt flow to the mold.
  • FIG. 2 shows a continuous casting mold 1 according to the invention. From the continuous casting mold 1 are only those for clarity Slab broad sides delimiting longitudinal walls 8, 9 shown. A lower region 8 ', 9' of the mold 1 below the horizontal R1 is arcuate, R1 simultaneously representing the radius of curvature of this lower mold section.
  • the located on the outside of the mold longitudinal wall 8 passes from the curved wall section 8 'tangentially into a cross section on the pouring side widening straight section 8'.
  • the transition point 10 from the curved wall section 8 'to the straight wall section 8' is below the horizontal R1.
  • the space 11 and, depending on the position of the tangent 12 an additional space 13 is created.
  • the mold wall 9 is arched in both sections 9 ', 9', so that it runs in an arc shape. If the thickness dimension and the immersion nozzle used allow the upper side wall section 9 ⁇ to be designed as a straight wall section, the straight boundary surface lying in the plane of the tangent 12, which is perpendicular to the horizontal R1.
  • Fig. 3 the continuous casting mold 1 is shown cut vertically in the middle, so that only the rear half of the continuous casting mold 1 is shown.
  • the located on the outside of the arc longitudinal wall 8 of the continuous casting mold 1 passes from the curved wall section 8 'tangentially only in the central region of the longitudinal wall 8 in a straight-walled section 8 ⁇ .
  • the additional space 13 is limited in the width extension of the mold for receiving a diving spout.
  • Fig. 4 also shows a mold in longitudinal section. Compared to FIG. 3, the only central extension is laid in the side wall 9 on the inside of the continuous casting mold 1.
  • the tangential transition point 10 from the curved wall section 9 'to the straight wall section 9 ⁇ lies above the horizontal R1 with the gain in space at 13 for the immersion nozzle.
  • the advantages of the continuous casting mold according to the invention lie in the low absolute deformation of the continuous shell within the mold, the smaller deformation density, the optimized space for the immersion nozzle and the low overall height of the system. Furthermore, in the embodiment according to the invention, no change to the water tank surrounding the mold wall panels is necessary, since necessary design measures are only carried out in the area of the copper wall panels. Last but not least, the geometry of the mold ensures good strand guidance during casting, so that the risk of strand suspensions and breakthroughs is reduced.
