Effect of relative reduction of billet height on forming progress of long-axis heavy forgings

摘要：

Relative reduction of billet height is one of the most important parameters of the forging process, which has great influence on forging quality. The inner defects compaction analysis models and the material damage analysis models of squaring, stretching and chamfering processes of long-axis heavy forging were established based on the software DEFORM-3D, and the influences of the relative reduction of billet height on the inner defects compaction and the material damage were analyzed through numerical simulation. The results show that with the increase of the relative reduction of billet height, the material damage and the compaction effect increase; compared with squaring and stretching, the relative reduction of billet height during chamfering has less effect on the inner defects compaction and the material damage.
