摘要
分析了降低拉拔功和界面作用力的途径，对提高钢丝机械性能的机理及方法进行了详细的讨论。并就上述提出的工艺方式的实施效果，进行了定性或定量的分析．
In this article,the method was analysed in which drawing force and action force between wire and die hole wall is decreased.It is also discussed in detail how mechanism and working technology of wire property is improved.The effect that working method was presented has been analysed qualitatively and quantitatively.
