Abstract (en)
[origin: EP1411140A1] Production of a steel strip or sheet comprises casting a steel melt into slabs or thin slabs, heating to at least 1000degrees C, hot rolling using a strip end speed of at least 10 m/s into a hot strip, coiling, cold rolling to form a cold strip, and recrystallization annealing. The steel melt contains (in wt.%) less than 0.1, less than 0.5 Mn, less than 0.03 P, less than 0.03 S, less than 0.1 Al, less than 0.01 N, less than 0.1 Ti, less than 0.05 Nb and less than 0.01 B with a balance of Fe and the usual impurities.
