Definitions

  • the invention relates to a continuous caster for guiding strands.
  • the object of the invention is therefore to design the continuous casting installation 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 the fact that the concave strand guide i ⁇ area of the mold and the thus convex strand ensure guiding and centering of the strand, which leads to a surface-specific uniform contact of the strand in the mold, which results in a high degree of symmetry in the formation 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 is symmetrical to
  • the central axis (12) has a concave shape that is constant from the upper edge of the mold (9) to the exit of the mold (10) and beyond to the last roll (7n) of the strand guide.
  • 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 ⁇ .
  • the shape of the mold in the area of the concavity can be linear, but also not linear, symmetrical to central axes (12) and (6).
  • pouring is carried out using immersion spout (1a) and casting powder (1b).
  • immersion spout (1a) and casting powder (1b) are also possible in the sense of this invention.
  • the constant concavity of the broad sides specified in the mold is continued in the strand guide by non-cylindrical (concave) or rollers that deflect under load in the elastic range up to the last roller (7n) of the strand guide, up to which - at the maximum possible casting speed - the Maximum swamp tip (7d) can penetrate.
  • 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 and kept constant until the end of the strand machine.
