Definitions

  • the invention relates to a continuous casting mold for guiding strands.
  • the object of the invention is therefore to design the continuous casting mold in such a way that the swinging of the strand, which is also known in the literature as "snaking", is prevented.
  • the object is achieved by the features of claim 1.
  • the remaining claims contain embodiments of the invention according to claim 1.
  • Fig. 1 Section of a mold with strand guidance in the casting direction
  • Fig. 2 Section of a mold, horizontally
  • Fig. 3 Section of a mold, horizontally
  • the invention now consists in that the concave strand guide in the area of the mold and thus the convex strand ensure guiding and centering of the strand, which leads to a surface-specific, uniform contact of the strand in the mold, whereby a high degree of symmetry in the Formation of the strand shell with regard to
  • a slab system is described in Fig. 1-3, which consists of a width-adjustable mold (1), the broad sides of which have a concave shape symmetrical to the central axis (12), from the upper edge of the mold (9) to the exit of the mold (10) is constant or uniformly reduced to a rectangular format.
  • the concavity or the convex slab has a height (17) of max. 5% of the slab thickness based on the strand thickness (2a).
  • the profile runs linearly parallel to one another or also with an angle of repose (19) ⁇ . the max. Is 2 ⁇ .
  • Di "shape of the mold in the area of the concavity can symmetrically to the central axes (1., And (6) but not be linear.
  • pouring nozzle (1 a) and casting powder (1b) are molded.
  • pouring without immersion pouring and casting powder possible in the sense of this invention.
  • the constant concavity of the broad sides specified in the mold is reduced to the rectangular shape in the strand guide or is uniformly reduced over the length of the mold and already enters the strand guide with a rectangular format at the outlet of the mold.
  • a corresponding shape can also be selected for blooms (Fig. 4) and billets (Fig. 5).
  • two opposite sides or all four sides of the strand can be convexly shaped in the mold.

Abstract

L'invention concerne une coquille de coulée continue permettant de produire du métal coulé en continu se présentant sous forme de brames, de brames minces, de blooms et de billettes. Cette coquille de coulée continue permet d'atteindre une grande fiabilité de coulée à des vitesses de coulée allant jusqu'à 6 m/mn. Grâce à la forme bombée de la coquille, le metal coulé est centrée par ladite coquille pendant le coulage, ce qui élimine le risque que la croûte solidifiée ne se déplace latéralement dans une des directions des petits côtés (mouvement oscillant). Ce déplacement symétrique de la caisse pendant le coulage dans la coquille, permet d'obtenir une structure symétrique régulière de la crôute solidifiée, de son champ de températures (isothermes), des forces d'extraction et des contraintes exercées sur la crôute solidifiée par rapport à l'axe d'un métal coulé dans le sens de coulée, même lorsque la barre effectue un mouvement oscillant dans la zone de son guide.
