초록
In this study, we developed a control method for a forming roller used in a spinning process at an elevated temperature for manufacturing dome parts of a high-pressure vessel. The sequence and forming path of the forming roller were determined by the number of passes in the hot spinning process and dome radius. To verify the reliability of the proposed method, an FE (finite element) analysis under the Forge software environment and spinning experiments were performed using a 34CrMo4 alloy steel pipe with an outer diameter of 559 mm and thickness of 16.5 mm. The FE analysis and experimental results indicated that the roller control method provided a successful dome shape.
