FIELD: metallurgy.
SUBSTANCE: regulation of deformation site is implemented by means of movement by axis of rolling pairs, with cam profile. Exclusion of form deviation of sheets at considerable width of spectrum of products, which are displayed in the form of quaternary waves, is provided ensured by at formation of necessary profile of deformation site for two chosen shift location, rollers contours of rolling pair is implemented so that in deformation site, they give symmetrical relative to rolling centre profile with maximum of profile in the rolling centre, changing at rollers shift, while rollers contours at least of the second rolling pair in deformation site forms profile, symmetrical relative to rolling centre with two equal, changing at rollers shift by maximums out of rolling centre. Rollers of rolling mill are implemented with corresponding contours.
EFFECT: exclusion while rolling of sheets or strips deviation from required profile because of superdistension in fringe regions (quarters), in rolling mills wit working roll, which bear on backup rolls or intermediate rolls with backup rolls.
