METHOD AND DEVICE FOR PRODUCING A METAL STRIP FOR TAILORED BLANKS TO BE CUT TO LENGTH

摘要

The invention relates to a method for producing tailored blanks by hot-rolling a strip, and to a device for carrying out the method. The tailored blanks to be cut to length from the rolled strip are obtained by cooling or heating the hot strip in sections, so that it experiences a different reduction in thickness in the individual sections whilst the roll force remains essentially constant, the sections having been given a different yield stress value due to the different temperature settings.
