Abstract
PURPOSE: To obtain a conductive material for electric wires of superior mechanical strength and conductivity by supplying the mixed powders of good conductive metallic powder and dispersion intensified type alloy powder into the container equivalent flow passage of an extruder formed by a hollow-grooved rotary wheel.
CONSTITUTION: When mixed powders 7 of good conductive metallic powder for matrix and oxide for dispersion phase are loaded into a hopper 6, and a screw 3 is rotated, the mixed powders 7 are kneaded in a material flow passage 5, and the mixture arrives at the material supply port 9a of a continuous extruder 8. Thence, it is supplied to a container equivalent flow passage 9, and while it is being pressed by the friction force that it receives from the hollow groove 10 of a grooved rotary wheel 11, it is advanced forcibly to the die 16 side. At this time, the matrix phases continuously integrate near the die 16 and turn to a metallic fluid state. Thereby, the dispersion intensified type alloy wherein the hard layers of the metallic oxide are uniformly dispersed in the good conductive metallic matrix is extruded in the form of a wire material as a conductor material 17 for electric wires through the die 16.
