核电厂汽轮机转子叶片的荧光磁粉检测
Fluorescent Magnetic Particle Inspection for Nuclear Power Plant Turbine Rotor Blades
摘 要
介绍了使用线圈法和磁轭法对汽轮机转子叶片进行荧光磁粉检测的步骤及技术要求.通过试验确定了合适的检测工艺,并对汽轮机转子叶片进行了实际检测,同时进行了与渗透检测的对比试验,试验表明:荧光磁粉检测法能有效检出叶片端部、齿根及叶身表面的较小缺陷,具有较高的检出灵敏度,可靠性较高,适用于叶片类不规则形状产品的在役检验.

Abstract
This paper introduces the steps and technical requirements for the fluorescent magnetic particle testing of steam turbine rotor blade by using the method of coil and magnetic yoke.Suitable technological parameters for the test were identified through experiment and the actual testing of steam turbine rotor blade was performed,and at the same time a contrast experiment was made with penetration detection.The test showed that the fluorescent magnetic particle detection method could effectively detect smaller defects in the blade end,root and surface of the leaf body with high sensitivity and high reliability for in-service inspection of blade and other irregular shape of products.
