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精密陶瓷在高温下制钨过程，研究了钨和孔表况及两者间互关系，讨论了使用寿命及其磨损机理。

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置，以降低拨后钢传道线卷筒表残余热量，拨具工作温度。
