초록
The steel structure of the Molten steel carrier is eroded due to environmental conditions such as high temperature and corrosion, and corrosion and erosion reduce the thickness of the structure and cause erosion around gas outlets. Since this increases the stress of the structure, it is necessary to study the safety of the structure. In this study, fatigue properties were estimated using the expert system that can estimate fatigue properties based on mechanical properties such as tensile strength or hardness, and the fatigue strength of the structure was evaluated using the estimated fatigue properties. As a result, the evaluated fatigue life was greater than 106 cycles, indicating that it has sufficient fatigue strength.
