Wall thickness uniformity of railway hollow shafts by cross-wedge rolling

Wall thickness uniformity is an important quality criterion of railway hollow shafts by multi-wedge synchrostep cross wedge rolling. The stable rolling condition of railway hollow shafts in this rolling process is analyzed,and a flattening instability criterion is presented. Based on this result,a r...
