Abstract:
As an important connection part of metal equipment, bolt is widely used in hydraulic power plant. However, the bolt fracture of hydropower plant occurred occasionally, which seriously affected the stable operation of hydropower plant. Based on the analysis of the fracture bolt, the quality problems of the bolt were found: (1) the material is not qualified, (2) the mechanical properties of the bolts are not qualified. Because the misuse of the material and the wrong execution of the heat treatment, the actual strength of the bolts could not meet the nominal strength, leading to the fracture of the bolts during term of service. The detection of chemical composition and hardness testing can effectively monitor the testing quality of bolts, and prevent unqualified bolts into the installation and operation.
