Description of the Related Art A method for producing a composite single-core wire and a composite multi-core wire of this type is disclosed in Japanese Examined Patent Publication No. 59-26361. In this, as shown in FIG. 5, the primary composite material in which a carbon steel pipe is filled with stainless steel is formed into a billet having a square cross section by hot extrusion (primary hot pressing). This billet is gradually reduced in diameter by hole rolling,
For example, a composite single-core wire having an outer diameter of 8 mm is formed, and then a wire drawing treatment is performed to form a composite single-core wire having an outer diameter of 2.5 mm. A secondary composite material in which a large number of the composite single-core wire rods are filled in a carbon steel pipe is formed into a billet having a square cross section by hot extrusion (secondary hot pressing). The billet is successively reduced in diameter by hole rolling to produce a composite multifilamentary wire having an outer diameter of 13 mm, for example, and further drawn to obtain a composite multifilamentary wire having an outer diameter of 1.13 mm. When the carbon steel of the composite multifilamentary wire is dissolved and removed, for example, a stainless fine wire having a diameter of 12 μ, that is, a stainless fiber is obtained.

After performing the inclined rolling at 5%, and immediately after slipping out of the inclined rolling, a plurality of stages of hole-type rolling were performed to roll a composite multifilamentary wire having an outer diameter of 5.5 mm. FIG. 3 shows each inclined rolling ratio and the aspect ratio of the composite single-core wire rod in the rolled composite multi-core wire rod.

(T / D = 0.25) of 6 kinds of carbon steel pipes were filled, and each of them was inclined rolled at a rolling rate of 60%, and immediately after slipping out of the inclined rolling, a plurality of stages of hole-type rolling were applied to the outside. A composite multifilamentary wire having a diameter of 5.5 mm was obtained. FIG. 4 shows each t / D value and the aspect ratio of the composite single-core wire in the rolled composite multi-core wire. It was found that when t / D is 0.1 or more, the aspect ratio of the composite single core wire is 1.0 or more and 1.4 or less.

る。From the experimental data shown in FIG. 3 and FIG. 4, the secondary wire rod rolling (secondary inclined rolling + hole rolling) was performed on the material (secondary composite material) with t / D of 0.1 or more. The aspect ratio of the composite single-core wire rod is 1.0 or more and 1.4 or less by making the carbon steel pipe filled with the composite single-core wire rod and by setting the rolling rate of the inclined rolling to 60% or less. It can be seen that the core wire is obtained. From the viewpoint of work efficiency of the primary and secondary wire rod rolling, it is preferable that the rolling rate of the inclined rolling is 20% or more. If it is less than 20%, the production efficiency will be too low.
