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(中):
本发明涉及一种通过将圆柱形壳体2焊接到两个端壁3,4来制造钢扬克缸1的方法,使得圆柱形壳体2和端壁3,4一起形成扬基缸1。焊接操作是 仅从扬克缸1的外部进行,并且在焊接操作中进行对接焊接操作,其中在扬克缸1的内部使用背衬材料7,使得在每个端壁3,4之间 和圆筒形壳体1,形成单个焊道8,其在相对表面5,6之间一直延伸,并且分别完全熔合每个端壁3,4和圆柱形壳体2的相对表面5,6。
