FIELD: rolled stock production, namely mills for hot and cold rolling of wide strips. SUBSTANCE: four-high rolling stand includes rolling rolls profiled along curvilinear center-symmetry contour in the form of one period of sine. Profiles of upper and lower rolling rolls are equidistant ones. Rolling rolls are provided with means for their mutual axial motion in order to adjust profile of inter-roll gap. According to invention roll profile is strictly normalized by mathematical relation taking into account profile of rolled piece and many other technological parameters such as camber, wear, roll flattening, thermal crown of rolls, strip width, reduction value. EFFECT: enhanced planeness of rolled strip. 2 cl, 5 dwg
