Abstract

PURPOSE: To obtain comparatively long wire easily at one time with considerably great liquid surface processing degree from composite billet of great diameter by utilizing an insulating mixture of an inorganic powder and a binder by means of liquid extrusion.
CONSTITUTION: The castor oil 3 as a pressure medium and the three-layered composite billet 4 whose rear part is sealed with the copper plug 5 are arranged in place in the inside of the container 2 of the liquid pressure extruder 1, and extrusion is made by working the steam 6. Extrusion is made at a temperature of 250°C and an extrusion ratio of 120, and from the rear of the die 10, the extruded molding 11 processed into predetermined diameter by liquid surface processing is obtained.
