摘　　要：介绍了700℃超超临界锅炉再热器集箱候选的GH984G、HR6W铁镍基合金、617B和740H镍基合金等新材料性能。对选用HR6W、617B、740H大口径管制造的不同外径、不同设计温度的700℃超超临界锅炉再热器集箱进行了分析计算,分析了HR6W、617B、740H大口径管用于700℃超超临界锅炉再热器集箱的适用温度范围,提出了700℃超超临界锅炉各温度段再热器集箱选材建议。This paper reports the properties of GH984G, HR6W, 617B and 740H used for reheater header for 700 ℃ USC boilers. The strength of the reheater header made of HR6W, 617B and 740H piping with different diameters underdifferent temperatures are calculated. It also analyses the suitable service temperature by HR6W, 617B and 740H piping, and puts header material selection. range of 700 ℃ reheater header manufactured forward some suggestions on 700 ℃ reheater
