Influence Analysis of Block Wedge on Rolled-Piece End Quality in Cross Wedge Rolling
Rolled-piece end quality is one of key factors to decide material utilization ratio in cross wedge rolling (CWR). Good workpiece end quality can improve material utilization ratio effectively. In the paper, by adding the block wedge near the end of mould, it can block surface metal which flows faster in the axial direction and avoid the end concavity of rolled piece. The material loss will not be present and good end quality rolled piece will be produced. The results are significant for improving material utilization ratio and promoting applications of CWR.
