摘要
分析了影响叶轮内部质量的因素。通过对传统工艺方案进行改进,采用空心坯料进行最终镦粗成形,从而保证了叶轮内部质量,使厚轮毂叶轮超声波探伤及力学性能检验结果均符合标准要求。
This paper has analyzed the factors affecting the inner quality of large impellers.Through improving the traditional technology,the large impeller has been finally upset with the hollow blanks.Applying this new technology plan,the impeller＇s inner quality has been guaranteed and met the requirements well both ultrasonic testing and mechanical property.
