Abstract

The invention relates to a method for producing a hot strip from transformation-free ferritic steel, wherein a melt is cast into a roughed strip and the latter is subsequently rolled into a hot strip. For this purpose, it is provided that the melt is cast in a horizontal strip casting facility under conditions of a calm flow and free of bending into a roughed strip in the range between 6 and 20 mm and is subsequently rolled into hot strip having a degree of deformation of at least 50%.
