两江/满台城电站水轮机转轮叶片二次热弯成型工艺研究

Study on Technology of Profile Twice Shaping with Hot-bending for Runner Blade of Liangjiang/Mantaicheng Power Station

水轮机转轮叶片二次热弯成型技术是一门可以获得叶型准确、铲磨量小、价格适中、生产周期较短的制造技术。此项技术一直为国内外制造厂商高度重视。两江／满台城电站水轮机转轮叶片二次热弯成型新工艺的成功探索，尤其是对叶片回弹量的控制为今后转轮叶片的制造技术的发展提供了宝贵的经验。

By means of applying the technology of profile twice shaping with hot bending to turbine blade, the good accuracy and shape of profile molding, less grinding, fit price and short period of manufacturing are obtained. This technology is always taken for attention by turbine manufacture company in the world. The successful application of profile twice shaping at Liangjiang / Mantalcheng power station especially in controlling blade rebound provide the precious experience for development of runner blade manufacture technology.
