摘　　要：管板制造难度较大,而大型换热器SA765-Ⅱ管板又有-45℃的冲击要求,制造难度又加大。通过加强冶炼的控制,采用KD法锻造拔长以及中心压凸台、中心压凹台等多种压实方法,使用合理的热处理工艺参数,生产出了合格的大型换热器管板。As the manufacture of tube plate is difficult, and that large-scale heat exchanger SA765-II tube sheets have impacting requirements of-45 ℃, the manufacturing difficulty again increase. By strengthening the control of the smelting, adopting a variety of combining compaction method of KID stretching as well as forging convex sidestep of the center and forging concave sidestep of the center, using reasonable heat treatment parameters, the qualified large exchanger tube sheets were produced.
