FIELD: rolled stock production, namely configuration of rolls of rolling stands.
SUBSTANCE: in rolling stand having CVC-roll pair, mainly rolling CVC-rolls and pair of backup rolls with contact zone bcont, horizontal moment M causes roll drawing apart and provides occurring of axial efforts in bearing units of rolls. In order to provide minimum axial efforts in bearing units of rolls, moment M is lowered due to selecting profile of CVC-rolls determined by means of polynomial expression. In condition of optimized wedge shape of CVC-contour, the last is formed in such a way that tangent line to end portion diameter and to convex part of roll are mutually parallel and inclined relative to roll axes by optimal angle of wedge.
EFFECT: reduced values of moments acting upon bearing units of rolls in horizontal direction.
