A mill roll has a working layer comprising alternate portions of unequal wear resistance properties along both the circumference and the generating line of the roll barrel. Each portion of the working layer may have the form of a square, rhomb, circle and others, if viewed on a developed surface of the working layer, while, in a plane of the roll cross-section, it is arranged so that its axis of symmetry is inclined at an angle to the radius of the roll.
A mill roll comprising a barrel and a working layer deposited on said barrel and having alternate portions of at least two materials of a different wear resistance each correspondingly along both the circumference and the generating line of said barrel, each portion of said working layer, on a developed surface of said barrel, being a figure symmetrical about both the circumference of said barrel and the generating line thereof, and extending along the circumference of said barrel for 0.001 to 0.1 of contact arc length and, in a plane of the roll cross-section, the angle between the axis of symmetry of each portion of said working layer and the radius of the same roll is from +5.degree. to +75.degree..
