YANKEE DRYING CYLINDER AND METHOD FOR PRODUCING A YANKEE DRYING CYLINDER

摘要

A method for manufacturing a Yankee drying cylinder (1) made from steel, said method comprises the steps of: - welding at least one shell section (17) to form at least one cylinder section (18), which cylinder section (18) forms a cylindrical shell (2) of said Yankee drying cylinder (1), - machining of an inside surface and/or an outside surface of said cylindrical shell (2), - jointing a respective end wall (5, 6) to a respective end of said cylindrical shell (2) by welding such that the cylindrical shell (2) and the end walls (3,4) together form the Yankee drying cylinder (1), wherein a final machining step of an outer cylindrical surface (30) of the Yankee cylinder (1) is performed until a variation in a wall thickness in a circumferential direction of the cylindrical wall (31) of said Yankee drying cylinder (1) is 2,5 mm or less.
