A STEEL-MADE YANKEE CYLINDER |
摘要 |
The invention relates to a steel-made Yankee cylinder (1) that comprises a cylindrical shell (2) having two axial ends (3, 4). An end wall (5, 6) is connected to each axial end (3, 4) by a circumferential weld bead (7). 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). |
