Abstract
The invention relates to a process for the production of tailored blanks by the hot rolling of a strip and to an apparatus for the performance of said process. To obtain tailored blanks to be cut to length from the rolled strip, the hot strip is cooled or heated in portions, so that with a substantially constant rolling force the strip undergoes a differential decrease in thickness in the individual portions, which have been given a differential yield stress value by the differential temperature adjustment.
