Definitions

  • the invention relates to a continuous casting mold for guiding strands according to the Preamble of claim 1.
  • DE 39 07 351 A1 discloses continuous casting molds for thin slabs in their upper part, i.e. in the area of the inlet cross-section, with a funnel-shaped To provide recess. This measure does not affect the strand thickness however, on the casting speed.
  • molds are known from EP-A-498 296 and WO-A-89/12 516, at which the convex strand shape still in the mold on a rectangular format is withdrawn.
  • pouring disorders take the form of Breakthroughs significantly. This is a consequence of that at higher speeds occurring pendulum of the strand in the strand guide. He commutes in the direction the narrow sides back and forth. This oscillation leads to non-uniform contact of the strand with the mold narrow sides and thus to an asymmetrical Heat transfer and an asymmetrical isothermal profile in the strand shell both in the casting direction and perpendicular to it.
  • the object of the invention is therefore to design the continuous casting mold so that the Pendulum of the strand, which is also known in the literature as "snaking", prevented becomes.
  • Claim 2 includes an embodiment of the invention according to claim 1.
  • FIG. 1 serves to illustrate the invention.
  • FIGS 2-5 do not include the subject matter of the invention according to claim 1 but only serve to illustrate the necessary reference symbols.
  • a slab system is described in the figure, which consists of a width-adjustable mold (1), the broad sides of which is symmetrical to Have central axis (12) extending concave shape, which from the upper edge of the mold (9) until the mold (10) emerges is constant.
  • the concavity or the convex slab has a height (17) by Max. 5% of the slab thickness based on the strand thickness (2a).
  • the profile runs linearly parallel to one another or with a slope angle (19) ⁇ , the max. Is 2 °.
  • the shape of the mold in the concavity area can be symmetrical to the central axes (only 6 is shown here) be linear but not linear.
  • Immersion spout (1a) and casting powder (1b) eaten.
  • a corresponding shape can also be used for blooms and billets to get voted.
  • two opposite sides or all four Sides of the strand are convex in the mold.
