FIELD: metal processing.
SUBSTANCE: invention relates to rolling, specifically working roll stands of hot and cold rolling. Proposed roll comprises a carrier shaped axle with restrictive collar and matched with a band on landing. Band and its section of the carrier axle form the roll body. Shaped axle comprises two cylindrical sections with their longitudinal axes shifted to form an eccentricity.
EFFECT: reduced probability of the carrier axle and the band damage due to reduction of stress concentration in the place of connection of adjacent sections is ensured by the fact that the carrier shaped axle is made with the cylindrical section arranged between said sections and inclined to the roll axis of rotation at the angle of α, specified by a mathematical expression, and the band matches the carrier axis.
