Definitions
- the invention relates to a continuous caster and a method for producing thin slabs.
- the object of the invention is to provide a method and a continuous caster, which make it possible to achieve a predetermined thickness of the thin strand in that optimal conditions for the supply of slag and for reducing the strand thickness are achieved in the mold and in the guide frame during the casting roll.
- Fig. 1 Representation of the casting conditions in the mold
- Fig. 2 Technical effort for constant surface quality and casting performance depending on the slab thickness based on a 200 mm thick slab x 1,000 mm width
- Fig. 4 Hydraulic behavior of the steel in the mold as a function of the slab thickness based on a 200 mm thick slab x 1,000 mm width
- the turbulence caused by the metal flowing into the mold has a considerable influence on the relation (1), which often continues to the bath level and can lead to wave movements, whereby the wave crests can rise above the slag level, which leads to an interruption in the lubrication.
- This turbulence depends, among other things, on the throughput and the thickness and width of the mold at the dip tube outlet cross section.
- the hydraulic behavior is now defined as the quotient of throughput and thickness and can be represented with the following expression:
- an electromagnetic brake in the mold area can significantly reduce turbulence in the mold area.
- FIG. 5 An example of a continuous casting installation which contains all the features of the invention can be seen from (FIG. 5).
- FJA strand cross section of the solidified slab
