この発明は、異種金属板を一体的に層着することを目的
とした複合金属板の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing a composite metal plate whose purpose is to integrally layer dissimilar metal plates.
（従来の技術）

どである。(Prior art) Conventionally, the manufacturing method of a composite electrode material generally used is as follows: (1) An adhesive layer is provided between a molybdenum plate material and a copper plate, and cold rolling is performed to bond the molybdenum plate material and the copper plate material. (2) A method of bonding a molybdenum plate and a copper plate to produce a composite electrode material, or (2) a method of laminating a molybdenum plate and a copper plate and joining them by hot rolling to produce a composite electrode material. (3) A method in which a molybdenum plate material and a copper plate are overlapped, wrapped in a stainless steel alloy or the like, heated and rolled, and then the stainless alloy is removed.

ブデン板と銅板とを完全に接合することが困難である。However, in (1) above, it is unavoidable that non-uniformity occurs in the adhesion mediating layer and the brazed part, resulting in uneven adhesive strength. Due to the difference in expansion coefficient, there are problems such as peeling between the molybdenum plate and the copper plate and warping of the composite electrode material. In addition, in method (2) above, molybdenum and copper tend to form an oxide film on their surfaces when heated in the air, and in particular, when molybdenum is heated to 500°C or higher in the air, it forms an oxide film on the surface of the molybdenum. There is a problem that the formed oxide film sublimes, and it is difficult to determine the atmosphere and heating temperature for hot rolling, making it difficult to completely join the molybdenum plate and the copper plate.

などの問題点があり、歩留りの低下は免れなかった。(Problems to be Solved by the Invention) In the conventional method for manufacturing composite metal plates, molybdenum plates and copper plates are overlapped and hot-rolled, so the thickness accuracy in the width direction of the product and the elongation of each material are important. The thickness of the molybdenum plate in the product is uneven due to the pre-processing of the surface of the molybdenum plate to give it a rough surface. (If the thickness is uneven, distortion will occur due to thermal expansion, and product deformation is inevitable.)
There were problems such as these, and a decrease in yield was inevitable.

A description has been given of hot rolling this. However,
If another metal tube is fitted on the outside of the composite material and hot rolled, a plate material (5 layers) in which three metals are layered can be easily manufactured. For example, if the metal tube and metal rod are insulated, five layers of metal can be used for separate electrical currents. The composite plate of the present invention is used for supporting composite electrode materials, especially semiconductors.

Therefore, even if the metal rod is made of a material with low tensile strength or is difficult to form an alloy. Even materials obtained by powder sintering can be made into composite plates.

Therefore, there is no room for the rolling thickness to vary locally, and the actual product is finished with the same thickness for each metal as shown in FIG. Therefore, since the metal plate of the product has uniform thermal properties on both sides, there is no risk of deformation due to thermal expansion, and there is no risk of distortion due to internal stress during long-term use. In addition, since the plate product according to the present invention has undergone equal processing on both the X and Y wheels, even if it is made into a punched product, there is no risk of distortion due to internal stress, etc. be.
またこの発明は、複合棒の直径によって製品厚みを設計
できる利点がある。また長尺製品が可能の為に歩留（例
えば９０〜９５％）が著しく向上する。Furthermore, this invention has the advantage that the product thickness can be designed depending on the diameter of the composite rod. Furthermore, since long products can be produced, the yield (for example, 90 to 95%) is significantly improved.
