付ロールを用いて、両方の金属条を同時に圧延すること
により両者を圧接することを特徴とする金属複合条の製
造方法である。[Means for Solving the Problems] The present invention has a first metal strip and a second metal strip whose width is narrower than that of the first metal strip. The angle between the side surface and the bottom surface is 110°~
155' and a grooved roll having a groove having a substantially trapezoidal cross section is used to simultaneously roll both metal strips to press them together.

るために、第２の金属条のエツジ部における接合状態が
悪くなり、一方、溝付ロールのなす角が１５５”を超え
てもエツジ部における接合状態が悪くなるからである。In this case, the angle between the side surface and the bottom surface of the groove of the grooved roll is
Set to 110@~155°. This is because if the angle formed by the grooved roll is less than 1000, the side surfaces of the second metal strip will be restrained by the side surfaces of the groove during pressure welding and will be extremely deformed. This is because the bonding condition at the edges becomes poor, and on the other hand, even if the angle formed by the grooved roll exceeds 155'', the bonding condition at the edge portions deteriorates.
溝付ロールの溝部の側面と底面とのなす角は、１３０’
〜１５５’であることが特に好ましい。The angle between the side surface and bottom surface of the grooved roll is 130'.
It is particularly preferable that it is 155'.
第２の金属条の幅は、溝付ロールにより良好に圧接する
ことができるように溝付ロールの溝部の底面の幅と同じ
若しくはそれよりも若干狭いことが好ましい。The width of the second metal strip is preferably the same as, or slightly narrower than, the width of the bottom surface of the groove of the grooved roll so that it can be brought into good pressure contact with the grooved roll.

形状の断面の溝部を有する溝付ロールを用いて行う。As shown in FIG. 2, when manufacturing a metal composite strip by pressing the second metal strip 22, 24 onto both sides of the first metal strip 20, the angle between the side surface and the bottom surface of each of the upper and lower rolls is This is carried out by using a grooved roll having grooves having an approximately trapezoidal cross section that are continuously provided in the circumferential direction and have an angle of 110° to 155°.

あり、断面が略台形状である溝部を有する溝付ロールを
用いて第２の金属条を押圧することにより、第１の金属
条に圧接しつつ圧延する。[Function] According to the method for manufacturing a metal composite strip of the present invention, the first metal strip and the second metal strip are overlapped and provided continuously in the circumferential direction, and the angle formed between the side surface and the bottom surface is is 110 @ to 155'', and the second metal strip is pressed using a grooved roll having a groove portion having a substantially trapezoidal cross section, thereby rolling the second metal strip while being in pressure contact with the first metal strip.
第２の金属条は、この溝付ロールの溝部の底面により押

内部応力が生じる。内部応力が蓄積されると塑性変形を
引き起こす。このため、第１の金属条と第２の金属条の
接合界面は、微視的に見ると長さ方向に広がると共に幅

２の金属条側面を拘束することによって生じる界面での
変形が防止される。この結果、第２の金属条のエツジ部
における接合強度が向上する。When the second metal strip is pressed by the bottom surface of the groove of the grooved roll, internal stress is generated near the bonding interface with the first metal strip. Accumulation of internal stress causes plastic deformation. Therefore, when viewed microscopically, the bonding interface between the first metal strip and the second metal strip expands not only in the length direction but also in the width direction. The grooves of the grooved roll used in the present invention have a cross-sectional shape that sufficiently allows this widthwise expansion. Therefore, deformation at the interface caused by the side surfaces of the groove restraining the second metal strip side surface, which occurs when a conventional grooved roll having a rectangular cross section is used, is prevented. As a result, the bonding strength at the edge portion of the second metal strip is improved.
