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 during casting in
- 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 the structure during the continuous casting
- This object is achieved according to the invention with a method for influencing the solidification of the partially still liquid core of slabs and billets of steel during the continuous casting, which is characterized
- Embodiments result from the dependent claims 2-7, as well as on the
- V gain factor ratio of the effective areas or lengths
- bfi cross-sectional width of the liquid strand content can be given a oscillation frequency of e.g. 2 Hz, the required oscillation amplitude can be determined to be at least 0.24 mm.
- 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.
