service life of die

The test results show that the zinc coat loss can be reduced as pass draughts increase by raising work cone angle rationally and reducing the bearing length, but which has not obvious effect on the mechanical properties of finished steel wire and the service life of die.

试验结果表明部分压缩率增大时，合理增大工作锥角度、减少定径带长度，可减少锌层质量损失，而对成品钢丝的力学性能和模子寿命影响不明显。
