Abstract

The invention relates to an intermediate product (IP) in the manufacturing process of a steel-made Yankee drying cylinder (1) for drying a fibrous web (W). The intermediate product (IP) comprises a shell (2) that has a circular cylindrical shape and extends in an axial direction about a central axis (A) and the shell (2) has two axial ends (3, 4) and an inner surface (5) in which circumferential grooves (6) are formed. For each axial end (3, 4), there is an end wall (8, 9) which is connected to the axial end (3, 4) by at least one weld bead (11) such that the shell (2) and the end walls (8, 9) define an enclosed space (V) within the intermediate product (IP). Each end wall (8, 9) has an outer surface (34, 35) that forms a part of the exterior surface of the intermediate product (IP) and an interior surface (32, 33) that faces the enclosed space (V) such that the interior surfaces (32, 33) of the end walls (8, 9) face each other and the inner surface (5) of the shell (2) and the interior surfaces (32, 33) of the end walls (8, 9) together form an interior surface (7) of the entire intermediate product (IP). Each axial end (3, 4) of the circular cylindrical shell (2) has a protruding guide (12) along at least a part of its circumference and each end wall (8, 9) has a protruding guide (13) along at least a part of its circumference that engages and cooperates with the at least one protruding guide (12) of the axial end (3, 4) of the circular cylindrical shell (2) to which the end wall (8, 9) is connected by the at least one weld bead (11). The protruding guides (12, 13) having opposing surfaces that abut each other to define a predetermined position of the end wall (8, 9) in relation to the shell (2) and in which predetermined position a circumferential groove (28) is defined between the end wall (8, 9) and the shell (2). The circumferential groove (28) extends from the outer surface of the shell (2) radially inwards to a bottom of the groove (28) which bottom is defined by at least one of the protruding guides (12, 13) and the protruding guides (12, 13) form a bulge (36) on the inner surface (7) of the intermediate product (IP) which bulge protrudes into the enclosed space towards the central axis (A) and the bulge (36) can be removed by grinding or machining such that, after removal of the bulge (36), there can be a smooth transition between the inner surface (5) of the shell and the interior surface (32, 33) of the end wall (8, 9).
