- the surface of the roll that has the largest area is referred to as the main surface.
- the roll has two main surfaces located opposite each other, and the surface connecting the main surfaces is referred to as the side surface.
- the first roll 111 to the fourth roll 114 may be made of steel, copper, a copper alloy, a tungsten-based alloy, a superalloy, or a cemented carbide alloy. A film may be formed on the surface of these metal materials to suppress the reaction between the liquid 30 and the rolls.
- the film may be, for example, a ceramic film such as titanium aluminum nitride or chromium nitride, or an amorphous carbon film.
- the first roll 111 to the fourth roll 114 may be made of ceramics such as silicon nitride, alumina, or zirconia to further reduce the reaction between the liquid 30 and the rolls.
- the materials of the first roll 111 to the fourth roll 114 may be the same as each other, may be different from each other, or some of the materials may be different from the other materials.
- a first concave groove 111a is formed on the side of the first roll 111 (see FIG. 6).

- a third concave groove 113a is formed on the side of the third roll 113.
- a fourth concave groove 114a is formed on the side of the fourth roll 114.
- the first groove 111a to the fourth groove 114a are each cut in an arc shape, and the grooves face each other to form a cylindrical space P1 .
- FIG. 5 shows an example in which the space P1 is filled with the core material 2 and the skin material 3 (or liquid 30).
- the first roll 111 to the fourth roll 114 may have the same shape as one another or may have different shapes as one another (for example, different roll diameters) as long as the space P1 can be formed.
- the guide member 120 has a tapered tip shape and a main body portion 121 that forms an internal space that penetrates from the tip to the end opposite the tip, and a clamping portion 122 that is provided on the outer periphery of the main body portion 121 and clamps the first roll 111 to the fourth roll 114.
- the guide member 120 is also formed with an opening 123 having a hole shape in which the size of the opening decreases from the opening of the main body 121 toward the clamping portion 122.
- the end of the opening 123 on the clamping portion 122 side is connected to the space P1 formed by the first roll 111 to the fourth roll 114.

- the protective tube 130 guides the core material 2 into the space P1 formed by the first roll 111 to the fourth roll 114.
- the core material 2 and the liquid 30 move together from the guide member 120 side to the roll side and pass through the space P1 .
- the liquid 30 is solidified due to a temperature drop when passing through the space P1 after being poured into the guide member 120.
- the temperature drop at this time is due to the heat dissipation caused by contact with the surfaces of the first roll 111 to the fourth roll 114 and the surface of the core material 2, and the liquid 30 becomes the above-mentioned molded product (skin material 3).
- a mixed layer 4 is formed between the core material 2 and the skin material 3.
- a notch continuing to the space P1 may be provided. This notch is formed, for example, in a part of the roll.
- the core material is not covered with the skin material by heating the core material or skin material, but rather the molten skin material is attached to the core material while being cooled as it passes through the rolls, so compared to other known manufacturing methods, the effect of heat is less and intermetallic compounds are less likely to be generated.
- the material needs to be heated for each wire drawing and rolling process, and repeated heat treatments can generate intermetallic compounds, but with the roll casting process, the heating process (passing through molten metal) only needs to be done once, so the generation of intermetallic compounds can be suppressed.
- the span from heating to cooling is relatively short, which has the effect of suppressing the generation of intermetallic compounds.
- Figs. 7 to 10 relate to a clad material produced with a core material of copper and a skin material of aluminum, with the skin material having a thickness of 500 to 800 nm.

- Fig. 10 is a diagram showing the composition ratio in the direction of the arrow starting from point B 2 shown in Fig. 9. Each composition ratio indicates the composition ratio in each composition region of copper and aluminum including the boundary between copper and aluminum.
- the region R 1 where the composition ratio of copper and aluminum is switched corresponds to the intermetallic compound generation region, i.e., the mixed layer formation region.
- the mixed layer formation region is set by the ratio of a predetermined component.
- it is set by the composition ratio of copper or aluminum, and for example, the range where the composition ratio of aluminum is 10% or more and 90% or less is set as the mixed layer formation region.
- the region R 2 where the composition ratio of copper and aluminum is switched corresponds to the intermetallic compound generation region, i.e., the mixed layer formation region. Comparing FIG. 8 and FIG.

- the thickness of the mixed layer was approximately less than 1.0 ⁇ m.

- the clad material 1 is produced by passing the heat-treated core material 2 and the liquid 30 through the space P1 formed by the four rolls while solidifying the liquid 30. According to this embodiment, the heated core material 2 is brought into contact with the liquid skin material 3, so that the clad material 1 can be produced in which the core material 2 and the skin material 3 are bonded with high bonding strength.
- the clad material can be produced with fewer work steps, without the need to join the core material and skin material that are produced separately, or to repeat annealing and drawing, as was done in the conventional method.
- Fig. 11 is a cross-sectional view for explaining the configuration of the main part of a clad material manufacturing device according to the first modified embodiment of the present invention, and the configuration of the wire material.
- the clad material 1A according to the first modified embodiment includes a prismatic core material 2A and a skin material 3A that covers the core material 2A, and a mixed layer is formed between the core material 2A and the skin material 3A.
- a groove corresponding to the clad material is formed in the roll used in the roll casting process.
- the other configurations are the same as those of the above-mentioned embodiment, so the description will be omitted.
- a V-shaped first groove 115b is formed on the side of the first roll 115.
- a V-shaped second groove 116b is formed on the side of the second roll 116.
- a V-shaped third groove 117b is formed on the side of the third roll 117.

- the first groove 115b to the fourth groove 118b form a rectangular (square) space P2 by facing each other.
- the core material 2A and the liquid 30 move together from the guide member 120 side to the roll side and pass through the space P2 .
- the liquid 30 solidifies near the surface of the core material 2A and the surfaces of the first roll 115 to the fourth roll 118, and becomes the skin material 3A.
- a mixed layer is formed between the core material 2A and the skin material 3A. In this way, the molded product according to this modification example 1 is produced.
- the clad material 1 produced in the embodiment is processed to obtain a clad material with a changed shape. Specifically, the clad material 1 is rolled to obtain a clad material having a flat plate shape.
