Combined with the practice of tail water accidents in Xianyou Pumped Storage Station three normal stress relief methods are introduced ineluding heat aging natural aging and vibration aging.The application of posited stress relief method of spot annealing and vibration aging in sluice gate manufacturing is emphatically introduced and the method has high efficiency and good energy saving.
