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精密陶瓷拉模在高温下拉制的过程，研究了模孔表面的状况及两者间的相互关系，讨论了拉模的用寿命及其拉磨损机理。

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.

卷筒内壁设备有冷却喷水装，低拉拨后的钢传道线卷筒表面的残余热量，拉拨模具的工作温度。
