摘　　要：为了提高传统吐丝管的使用寿命,通过对吐丝管的内壁进行渗硼,并进行结构优化设计,结果表明:吐丝机的稳定性得到提高,吐丝管内表面的硬度值可提高到2 096 HV,有效地延长了吐丝管的使用寿命。To improve the service life of the spinneret used in wire-feeding machine, the spinneret was boronized on its inner surface. And the spinneret＇s structure was designed according to the traditional one. The result shows that the spinnerets after boriding treatment can improve the stability of wire-feeding machine, and the hardness value of the spinneret on inner surface can increase to 2 096 HV, which can effectively prolong the spinneret＇s service life.
