The invention relates to a roll which is capable of adjusting transverse stress of the rolling deformation zone. The technical proposal of the roll is as follows: the roll surface profiles of an upperand an lower working rolls (1, 3) are formed by smoothly connecting two-side profiles (7, 5) and the middle profiles (9, 4); the two-side profiles (7, 5) of the upper and the lower working rolls (1,3) are oblique lines, or the two-side profile (7, 5) of any one working roll is an oblique line and that of the other working roll is a horizontal line; the middle profiles (9, 4) of the upper and thelower working rolls (1, 3) are wavy profiles which are mutually meshed, the wavy profiles are symmetrical to the axial perpendicular bisector of the upper and the lower working rolls (1, 3); ring-shaped hollow cavities (8, 6) are respectively dug at the two-end surfaces of the upper and the lower working rolls (1, 3), and the ring-shaped hollow cavities (8, 6) is U-shaped or V-shaped at the longitudinal section of the upper and the lower working rolls (1, 3). The roll which is capable of adjusting the transverse stress of the rolling deformation zone can reduce the spherical stress of the rolling pieces in the deformation zone, and can improve the transverse thickness difference of the rolling pieces while lowering the rolling energy consumption.
