ABSTRACT:
A method for producing thin slabs whereby the cross-section thereof is reduced during solidification in a continuous casting device wherein the strand guide adjacent to the mold includes wedge-shaped adjustable roller-strand sections for regulating the thickness of the strand or the thin slabs. The thickness of the strand is reduced only on one point of the strand guide below the first segment downstream from the mold in an area of the strand containing a liquid core by regulating the strand guide rollers with a soft transition. The segment following the segment situated directly after the mold comprises a pivoting point on the input side and an adjusting means arranged on the output side.
