Abstract (en)
[origin: US6438443B1] A method of presetting the roll nip profile of a roll stand for rolling a rolled strip is provided. The roll nip profile is influenced by output values for the roll nip profile and the tensile stress distribution being set over the roll nip profile. The output values for the roll nip profile is determined by using a roll nip profile model which calculates the roll nip profile. The calculated roll nip profile or an equivalent quantity is linked to a correction value, in particular by addition or multiplication, to form a corrected calculated roll nip profile, so that the roll nip profile model is adapted to the actual roll nip profile of the roll stand by using the correction value.
