| Abstract: | This paper introduced general situation of steam generator. Several bolts on the small floating head of steam generator broke after a period of operation. A scientific research institution made macroscopic inspection and micro-analysis to the causes for bolt breaking,emphatically analyzed bolt components and made metallurgic structure detection. Based on the analytical result and comprehensive analysis of bolt failure,suggestions and measures for bolt manufacturing were put forward. |
