Aiming at several compaction methods commonly used in the forging process of large rotor forgings,several commonly used core compaction indexes are selected.DEFORM-3D software was used to simulate the single-hammer screw down,one-time upsetting-drawing and twice upsetting-drawing processes of 199 t steel ingot.Through the comparative analysis of the simulation results,the compaction effects of different drawing methods are compared,which provides a basis for the selection and reasonable combination of compaction methods in actual production.
