Definitions
- the invention relates to a method for influencing the solidification of the still partially liquid core of slabs and billets of steel during the continuous casting and a strand guide for carrying out the method.
- segments are known whose upper frame can be moved in a controlled manner during casting in the thickness direction (position-controlled segments, in the case of SMS: CyberLink segments, in the case of VAI: smart segments). Some of these segments are able to perform this position control dynamically (CyberLink segments).
- a disadvantage of the first-mentioned devices or methods is the considerable additional expenditure on equipment and the considerable metallurgical effect.
- the second-mentioned devices or methods only applications are known that have a static effect on the cast strand or whose dynamic effect on the cast strand serves metrological tasks and is designed only for such.
- the object of the invention is to influence the structure during continuous casting by comparatively simpler means effectively.
- This object is achieved according to the invention with a method for influencing the solidification of the still partially liquid core of slabs and blooms of steel during continuous casting, wherein periodically a force or Weginrial on the broad sides of the strand and the force or Weginrial in the Production flow consecutive adjacent areas in push-pull, and the upper frame of the force or.
- Path effecting effecting segments not parallel process, but tilted are movable and wherein the segments generate against the resistances of the strand the Oszillationsvor Cyprus.
- the ratio of the effective surfaces is less favorable, because a generally shorter segment length faces a significantly greater height of the flow cross section. It follows in this area that in order to achieve the same effect stroke amplitude, frequency or their product must be about 10 times larger than in the area of the sump tip.
- volume change described results in a corresponding periodic change of the casting level.
- Their negative effects can be compensated for by always oscillating two (or more) segments in push-pull mode and thus restricting the flow to (one) region (e) within the strand guide.
- the aim of the tilting movement is to avoid sudden changes in the passline between each two adjacent oscillating segments in favor of a local slight bending stress in the strand shell at this point.

- Procédé pour influencer la solidification du coeur en partie encore liquide de brames et d'ébauches en acier au cours de la coulée continue, dans lequel une action de force, respectivement de trajectoire s'exerce de manière périodique sur les côtés en largeur de la barre, et l'action de force, respectivement de trajectoire a lieu par vibrations, caractérisé en ce que l'action de force, respectivement de trajectoire s'exerce de manière symétrique dans des zones voisines se situant les unes derrière les autres dans le flux de production, et les cadres supérieurs des segments exerçant l'action de force, respectivement de trajectoire ne se déplacent pas en parallèle, mais sont mobiles en inclinaison ; dans lequel les segments génèrent les processus d'oscillation à l'encontre des résistances de la barre.
- Procédé selon la revendication 1, caractérisé en ce que l'action de force, respectivement de trajectoire est réglée d'une manière telle que l'on génère, dans la zone d'influence - par rapport au coeur de la barre encore liquide - une modification périodique du volume qui donne lieu à un écoulement du coeur liquide orienté à l'encontre de la direction de coulée continue en direction de la surface du bain.
- Procédé selon la revendication 2, caractérisé en ce que le produit de la fréquence d'oscillation et de l'amplitude d'oscillation est supérieur/égal à 0,48 mm/s (2 Hz * 0,24 mm) jusqu'à 20 mm/s.
