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).

摘要： The invention relates to a method of making a steel Yankee cylinder 1 by welding a cylindrical shell 2 to two end walls 3, 4 such that the cylindrical shell 2 and the end walls 3,4 together form the Yankee cylinder 1. The welding operation is carried out exclusively from the outside of the Yankee cylinder 1 and in the welding operation is carried out as a butt welding operation in which a backing material 7 is used on the inside of the Yankee cylinder 1 such that, between each end wall 3, 4 and the cylindrical shell 1, a single weld bead 8 is formed which extends all the way between the opposing surfaces 5, 6 and completely fuses the opposing surfaces 5, 6 of each end wall 3, 4 and the cylindrical shell 2 respectively.

摘要： The invention relates to a method of manufacturing a Yankee drying cylinder 1 for drying wet fibrous webs W by heat. The manufacturing method comprising the steps of: providing a shell 2 which is a circular cylindrical steel shell 2 with two axial ends 3, 4 and the shell 2 having a diameter in the range of 2 m - 8 m. Circumferential grooves 6 are formed on an internal surface 5 of the shell during some part of the manufacturing process. An end cover 7, 8 of steel is provided for each axial end 3, 4 of the shell 2 and each end cover 7, 8 has a circular circumference. The method comprises welding each end cover 7, 8 to an axial end of 3, 4 the shell 2. According to the invention, each end cover 7, 8 is welded to its respective axial end 3, 4 of the shell 2 at 16 - 32 separate welding points 12a, 12b, 12c, 12d.....12x that are made in a sequence, one after the other, and separated from each other along the circumference of the end cover 7, 8. For at least the first 8 welding points 12a, 12b, 12c, 12d.....12x, the welding points 12a, 12b, 12c, 12d.....12x are made in pairs of two in which the second welding point 12a, 12b, 12c, 12d.....12x in a pair is made directly after the first welding point 12a, 12b, 12c, 12d.....12x of that pair and the second welding point 12a, 12b, 12c, 12d.....12x in each pair is placed at an angular distance along the circumference of the end cover 7, 8 which lies in the range of 175°- 185° from the first welding point of that pair.
