USC 발전용 HIP Rotor의 단조 공정 연구
Investigation on the forging process of HIP rotor for USC power plant
초록
To improve the efficiency of fossil power plant, the higher steam temperature and pressure are required. Ultra super critical(USC) system meets very well this requirement. The HIP rotor is one of the most important parts of turbine in USC system and its material is easy to crack during hot forging. In this study, the upsetting and cogging process far
