歩留を著しく低下させる。(Prior art) Rapidly solidified foil is produced by ejecting molten metal from a nozzle onto the surface of a rapidly rotating roll and rapidly cooling it into foil. The free surface on the opposite side has a different surface roughness. In other words, the roll surface is the surface that comes into contact with the roll that removes heat, and its surface roughness depends on the surface roughness of the roll.If the surface roughness of the roll is reduced, the roll surface will become smoother, but if Since the surface is not in contact with anything other than the outside air, there is nothing to reduce roughness. Therefore, it is difficult to make the flatness of the free surface constant, and in particular, the flow rate of the molten metal coming out of the nozzle increases at the center of the foil due to its viscosity, which tends to result in a foil with a large crown. In such a rapidly solidified foil, the crown ratio may exceed 20%, and when this foil is used for clad rolling, medium elongation occurs, causing waves and cracks, which significantly reduces the product yield.

れている。Manufacturing a cladding material by laminating and rolling rapidly solidified foils is disclosed in, for example, Japanese Patent Laid-Open No. 1-290217. According to this publication, the electrode material for electrolytic capacitors is made by laminating pure AI foil as a core material and 1-alloy foil as a laminate material on both sides, and crimping these materials by rolling. It is disclosed that the A1 alloy foil is heated to a high temperature to prevent damage during rolling due to the brittleness of the A1 alloy foil.
しかし、このような開示は、クラウンに基く圧延割れと
は別の問題である。However, such disclosure is a separate issue from crown-based rolling cracks.
（発明が解決しようとする課題）
前記したように、急冷凝固筒における自由面には、粗度
が大きく、大きなりラウンを発生することが多くある。(Problems to be Solved by the Invention) As described above, the free surface of the rapid solidification tube has a large degree of roughness, and large roundness often occurs.

The purpose of the present invention is to provide a clad rolling method that enables normal rolling.

A clad rolling method characterized by crimping.

As shown in the figure, the roughness is large in the center and a convex crown is formed. That is, the first
The figure shows an aluminum alloy foil with an average plate thickness of 0.17 mm, but the average roughness in the plate width direction is 0.042 mm.
Moreover, it can be seen that large roughness is concentrated on the center side. When the rapidly solidified tube is manufactured by a single roll method, the plate thickness deviation is large, and it is difficult to obtain a foil having a flat surface (plain surface).
このような材料を圧延すると、特に金属凝固箔の表面粗

１２％以上となる箔では正常な圧延が難しくなる。When such a material is rolled, normal rolling becomes difficult, especially when the metal solidified foil has a surface roughness-to-crown ratio (crown/cladding total thickness) of 12% or more.

発生する。FIG. 2 shows the relationship between the strain released by cracking (calculated value) and the crown ratio (crown of the upper and lower rapidly solidified cylinders relative to the total plate thickness) on the entry side of the rolling mill. That is, aluminum foil with a foil thickness of 0.2 mm is used as the core material, and the average thickness is 0.17 mm with various crowns as the laminating material.
This is the measurement data when clad rolling was performed at a rolling reduction of 20% with aluminum alloy foils of 2 mm thick placed on top and bottom.
When the entrance crown ratio is higher than 14%, the third
A crack C as shown in the figure occurs, and approximately 1 to 6% of strain is released. When the entry side crown ratio was 12 to 14%, no cracking occurred, but waves due to medium elongation did occur. Furthermore, the third
In the figure, 1 is a laminate (aluminum alloy rapidly solidified cylinder), 2 is a rolling roll, and arrows 3 indicate the action of force in two axial directions on the entry side of the rolling roll, which causes breakage.
上記の結果から、箔材を圧延してクラッド材とするには
クラウン比率を１２％以下にすれば良いことがわかった
。From the above results, it was found that the crown ratio should be 12% or less in order to roll the foil material into a cladding material.

A polishing means 7 is provided on the opposite side of the guide roll and is movable toward and away from the guide roll, and the polishing means 7 is brought close to the guide roll to polish the surface of the rapid solidification cylinder 1.

Note that the guide roll may also be movable, and does not need to be driven to rotate, and may be an idle roll. The polished powder 8 is dropped into a collection container and collected.

Even with two-layer cladding, it can be fully applied to materials with a large crown ratio.

The thickness deviation was 25% with respect to the foil thickness. on the other hand,
The thickness of the core material is Q, 2 mm, and a rolled material with a crown and deviation of approximately 0% is used. When rolling and joining art materials,
The total crown ratio on the rolling entry side is about 18%, which is 12
