The present invention relates to a method for continuous production zones thin steel, molten steel is introduced between two rotary cooling casting rolls 4 and 5 move in synchronism from the sump molten steel, casting the cast steel strip 6 is in the casting rolls 4,5 at least partially solidified to form a steel strip 6, the molten steel at least the following alloy components: less than 1% by weight of nickel (Ni), chromium less than 1 wt.% (Cr), less than 0.8 wt% carbon (C), in particular less than 0.4 wt% carbon (C), and contains at least 0.55 wt% of manganese (Mn), at least one surface of the casting rolls 4,5, random pattern shape in, the casting rolls uniformly dent over 4,5 surface is disposed, further, 150N / mm from the roll separating force is 5 in the casting roll 4 and 5, is set and / or regulated in particular from 5 to between 100N / mm there.
