However, this manufacturing process cannot be used for materials such as Ti, Co, or their alloys, which are difficult to cold-deform, and hot forging, which has poor manufacturing efficiency, is required. A great deal of effort was put into manufacturing it, as it had to be finished to the required dimensions.

In this method, first, as shown in the front view of FIG. 1, a material to be rolled is inserted into a round steel material 1 that is easy to hot-work. After drilling a hole and inserting the rolled material s of a metal that is difficult to cold work obtained by hot groove rolling into the hole, the round steel material 1 is made as shown in the cross-sectional view of FIG.
Each time, hot rolling is performed again using hot groove rolls. And according to this method, for example the outer diameter:
60mmφ x length: 300mm round steel material 1, diameter: 9.5mm
When a rolled material s of φ x length: 300 mm is inserted and hot groove roll processing is performed, the rolled material s has a diameter of 1.5 mm.
It can be plastically deformed to a size of mmφ x length: 12mm, making it possible to mold small-sized products that would otherwise be impossible to manufacture by cold working, even by hot working. Ta.

となるのである。 This invention proposes a method for manufacturing wire rods and rods made of metals that are difficult to cold work, which solves the problems of the conventional methods described above. A plurality of large-diameter long rolled materials made of cold-workable metal are inserted, a relatively small-diameter metal wire is inserted between the rolled materials as a pressurizing medium, and the above-mentioned Between the rolled material and the metal wire,
The main process is to fill the pipe with ceramic powder as an anti-crimping agent, seal it, and then hot-roll it to reduce its diameter.The main process is to take out the rolled material from this reduced-diameter sealed metal pipe. This method is characterized by a method for manufacturing wire rods and bars made of metals that are difficult to cold work, and according to this method, there is no need to drill holes for inserting the rolled material into the round steel material as in the conventional method described above. This makes it possible to manufacture wire rods and bars with high efficiency and at low cost, and since there is no particular restriction on the length of the rolled material, it is possible to manufacture long wire rods and bars.
