摘　　要：长期以来,我国引进型反动式工业汽轮机的转速由于受到低压扭叶片材料的限制,不能满足某些特定运行场合高转速的要求。论述了用钛合金低压扭叶片提高工业汽轮机极限转速的可行性。Since long time speed of licensed reactionary industrial steam turbine made in China was limited by material of LP twisted blading, therefore, could not meet high speed requirement for certain applications. This paper discusses the feasibility to raise maximum speed of industrial steam turbine with titanium alloy LP twisted blading.
