A so-called overlay type metal composite strip formed by joining a second metal strip 22 to the entire surface of the first metal strip 20;
As shown in FIG. 3, there is a top lay type metal composite strip in which a narrow second metal strip 32 is formed on the surface of a first metal strip 30 so as to have an island-like cross section.

を圧接し同時に圧延して製造される。The overlay type metal composite strip is produced by roughening and cleaning the joint surfaces of the first metal strip 20 and the second metal strip 22, and then using a pair of upper and lower flat rolls to align the joint surfaces and press them from above and below. The first metal strip 20 and the second metal strip 22
It is manufactured by pressure welding and rolling at the same time.
一方、トップレイタイプ金属複合条は、第１の金属条３

0 and the second metal strip 32 are cleaned in advance, and a flat roll is placed on the first metal strip 30 side, and a rectangular cross section that matches the second metal strip 32 is placed on the second metal strip 32 side. It is manufactured by simultaneously rolling the bonding surfaces together using a grooved roll having grooves and pressing them from above and below.
［発明が解決しようとする課題〕
しかしながら、トップレイタイプ金属複合条は、幅の狭

のため、その後の工程において剥離を起こす危険性があ
り、工業的にはほとんど使用されていない。[Problems to be Solved by the Invention] However, the top lay type metal composite strip has a poor bonding condition at the edge portion of the narrow second metal strip. For this reason, there is a risk of peeling in subsequent steps, so it is hardly used industrially.
本発明は、かかる点に鑑みてなされたものであり、幅の
狭い金属条のエツジ部における接合状態が良いトップレ

とができる金属複合条の製造方法を提供することを目的
とする。The present invention has been made in view of the above points, and provides a metal composite strip that can efficiently obtain a top-lay type metal composite strip that has a good bonding condition at the edge portion of a narrow metal strip while preventing deformation. The purpose is to provide a manufacturing method.
［課題を解決するための手段］
本発明は、円周方向に連続して設けられた断面が略矩形
状の溝部を有する溝付ロールを用いて、第１の金属条と
、幅が前記第１の金属条より狭く、かつ、前記溝付ロー
ル溝部の底面の幅の０．５〜０．８倍であり、厚さが該
溝部の深さの１．５〜２．５倍である第２の金属条とを
、該溝部の底面で該第２の金属条を押圧することにより
圧延しつつ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 uses a grooved roll having a groove section continuously provided in the circumferential direction and having a substantially rectangular cross section, and using a grooved roll having a groove section having a substantially rectangular cross section, The metal strip is narrower than No. 1, and is 0.5 to 0.8 times the width of the bottom surface of the grooved roll groove, and has a thickness of 1.5 to 2.5 times the depth of the groove. This method of manufacturing a metal composite strip is characterized in that the two metal strips are pressed together while being rolled by pressing the second metal strip with the bottom surface of the groove.
ここで、第２の金属条の幅は、溝付ロールの溝部の底面
の幅の０．５〜０，８倍に設定する。Here, the width of the second metal strip is set to 0.5 to 0.8 times the width of the bottom surface of the groove of the grooved roll.
これは、第２の金属条の幅が溝部の底面の幅の０．５倍
未満であると得られる複合条の形状が変形し、第２の金
属条の幅が溝部の底面の幅の０．８倍を超えると圧接の
際に第２の金属条の角部が溝部の側面に衝突し第２の金
属条の形状を変形させるからである。This is because if the width of the second metal strip is less than 0.5 times the width of the bottom surface of the groove, the shape of the resulting composite strip will be deformed, and the width of the second metal strip will be 0.5 times the width of the bottom surface of the groove. This is because if it exceeds 8 times, the corners of the second metal strip collide with the side surfaces of the groove during pressure welding, deforming the shape of the second metal strip.
第２の金属条の厚さは、溝部の深さの１．５〜２．５倍
に設定する。これは、第２の金属条の厚さが溝部の深さ
の１．５倍未満であると第１の金属条と第２の金属条と
の接合状態が悪くなり、第２の金属条の厚さが溝部の深
さの２．５倍であると得られる複合条の形状が変形する
からである。The thickness of the second metal strip is set to 1.5 to 2.5 times the depth of the groove. This is because if the thickness of the second metal strip is less than 1.5 times the depth of the groove, the bonding condition between the first metal strip and the second metal strip becomes poor, and the second metal strip This is because if the thickness is 2.5 times the depth of the groove, the shape of the resulting composite strip will be deformed.
なお、第１の金属条の金属と第２の金属条の金属は、異
種でも同種でもよい。また、上下ロールに両方とも溝付
ロールを使用して、第２の金属条を第１の金属条の両面
に圧接しても良い。圧延は、従来行われている条件で行
う。Note that the metal of the first metal strip and the metal of the second metal strip may be different or the same. Alternatively, both the upper and lower rolls may be grooved rolls, and the second metal strip may be pressed against both surfaces of the first metal strip. Rolling is performed under conventional conditions.
［作 用コ
本発明の金属複合条の製造方法によれば、円周方向に連
続して設けられた断面が矩形状の溝部を有する溝付ロー
ルを用いて、第１の金属条と、幅が溝部の底面の幅の０
．５〜０．８倍であり、厚さが溝部の深さの１．５〜２
．５倍である第２の金属条とを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 width are is the width of the bottom of the groove.
．． 5 to 0.8 times, and the thickness is 1.5 to 2 times the depth of the groove.
．． It is rolled while being pressed against a second metal strip that is 5 times as large.
第２の金属条は、この溝付ロールの溝部の底面により押
圧されることにより、第１の金属条との接合界面近傍で
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
方向にも広がる。本発明に使用される溝付ロールの溝部
は、溝部の底面の幅を第２の金属条の幅に対応して規定
しているので、この幅方向の広がりを充分に許容する。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. Since the width of the bottom surface of the groove of the grooved roll used in the present invention is defined in correspondence with the width of the second metal strip, this expansion in the width direction is sufficiently allowed.
また、溝部の深さも第２の金属条の厚さに対応して規定
しているので、圧接の際に複合条が変形するのを防止す
る。したがって、溝部の側面が第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。Further, since the depth of the groove is also defined in accordance with the thickness of the second metal strip, deformation of the composite strip during pressure welding is prevented. Therefore, deformation at the interface caused by the side surfaces of the groove restraining the second metal strip side surfaces is prevented. As a result, the bonding strength at the edge portion of the second metal strip is improved.
