随着冶炼、锻造及检验技术的提高,目前已有多台采用整锻式实心转子体的汽轮机投入运行或正在安装。介绍整锻式汽轮机实心转子体超声波检验的基本要求、检验方法和验收标准,可为电厂和汽轮机制造厂同类型产品的检验提供参考。
With the improvement of smelting, forging and inspection technologies, there are already several steam turbines that use a forged solid rotor body to put into operation or are being installed. This paper introduces the basic requirements, test methods and acceptance criteria of the solid rotor body ultrasonic testing of the forged turbine, which can provide reference for the test of the same type of products in the power plant and steam turbine manufacturing plant.
