  • Steel-made yankee cylinder
    Patent number: 9206549
    Abstract: The invention relates to a steel-made Yankee cylinder (1) that comprises a cylindrical shell (2) having two axial ends (3, 4).

The cylindrical shell has an inner surface (8) in which circumferential grooves (9a, 9b, 9c, 9d, 9e) are formed. From the outermost circumferential groove (9a) at each axial end (3, 4) to the circumferential weld bead (7) at that axial end (3, 4) the wall thickness (T) of the cylindrical shell is either constant or decreasing and the depth (d1) of the circumferential grooves increases axially from the outermost circumferential groove (9a).
