要がない場合を包含する。As shown in FIG. 1, a method for producing a clad material according to the present invention comprises two types of metal strips (1,
Clad material (3) consisting of continuously pressing 2) and then removing stress by annealing and supplying to the next step
In the production of, the heating is performed by the infrared lamp (4) from the side of the metal band (1) for which the need for annealing is relatively large, and the metal band (2) for which the need for annealing is relatively small is provided.
By bringing the side of into contact with the water cooling plate (5) to cool it,
It is characterized in that the purpose of annealing is achieved while preventing the formation of intermetallic compounds at the joint surface (6) of two kinds of metals.
The phrase "need for annealing is relatively small" includes the case where there is substantially no need for annealing.

にするとよい。The water cooling board (5) is made of copper or other soft material having excellent heat conductivity and is hollow, and has a sufficient cooling capacity by passing cooling water inside. If necessary, a temperature of 0 ° C. or lower can be achieved by selectively using an appropriate cooling medium instead of water. In order to ensure surface contact with the clad material (3), the cross-sectional shape may be slightly rounded in the traveling direction and the width direction of the material.

もない。In the illustrated process, the annealing process, which characterizes the present invention, is carried out subsequent to the pressure welding process. However, if desired, both processes are performed separately, and after the joining, the clad material is once wound and the annealing process is performed again. It goes without saying that you can call it.

る。The clad material of the stainless steel plate and the aluminum plate described above will be explained as an example. The temperature gradient in the clad material cross section during annealing is as shown in FIG. 2 according to the thickness and thermal conductivity of both materials. . If sufficient cooling is performed from the aluminum side (back surface temperature Tb), the temperature at the joint with stainless steel (joint surface temperature Ti)
Is kept low, and the formation of intermetallic compounds hardly progresses. On the other hand, if the surface of the stainless steel is sufficiently heated (surface temperature Tf), a certain depth from the surface is maintained in a temperature range where the annealing effect is high (Ta or higher in the figure), and annealing proceeds. The internal stainless steel portion has an annealing effect that decreases as the temperature decreases, but it is possible to secure the desired annealing effect in the stainless steel layer as a whole.

る。In this way, the necessary annealing can be performed while suppressing the formation of intermetallic compounds in the joint surface inside the clad material. As understood from the mechanism described above, the degree of cooling is determined from the viewpoint of keeping the temperature of the joint surface at a limit at which the formation of intermetallic compounds does not proceed.
