wortle

This paper is described to draw tungsten wire with ZTA precision ceramic wortle at a high temperature, The profiles of tungsten wire and mould hole and the relation between them are researched.

阐述ZTA精密陶瓷拉丝模在高温下拉制钨丝的过程，研究了钨丝和模孔表面的两者间的相互关系，讨论了拉丝模的用寿命其拉丝磨损机理。

In order to lower residual heat on the surface of the block,the cooling mans is installed in interwall of the block.The wortle is soaked in cooling watr to reduce its working temperature.

卷筒内壁有冷却喷水装置，以降低拉拨后的钢丝传道线卷筒表面的残余热量，拉拨模具的工作温度。
