１．６号公報）。Conventionally, in order to manufacture a composite metal strip, a method has been used in which a different metal cladding with a cross-sectional area somewhat smaller than the groove is embedded in a groove formed in the joint surface of a metal strip serving as a base metal. In addition, recently, the cross-sectional area of 1.1 to 1.5 of the groove formed on the joint surface of the metal strip that becomes 4-smetal has been
A method has been proposed in which metal strips of different types having twice the area of 119F are rolled while being fitted together.

This is a cross-sectional view showing an example in which the deformation resistance ratio (hardness Hv) of a metal strip 1 made of -C, S metal and a dissimilar metal strip 2 clad on the metal strip 1 is 0.80 to 3. In a combination in the range of 0, when the metal strip 2 to be clad is fitted into the groove 3 provided in the metal strip 1 serving as the base metal and rolled joined, according to the present invention, the cross-sectional area S1 of the groove 3 is The metal strip 2 is shaped like a groove 3 so that the cross-sectional area S2 of the metal strip 2 that clasps against the groove 3 is 1.5 to 1.9 times larger.
By fitting and joining these by pressing,
The metal strip 2 strongly compresses the metal strip 1 and at the same time deforms in the rolling direction to strengthen the joint between the two metal strips in the groove.
As shown in the figure, a composite metal strip having a linear joining boundary line 4 and a desired composite ratio t2/l+ can be obtained.

接合が不良であることが分る。Figure 3 shows a 4g gold strip cladding on the horizontal axis.
Take the value S 2 / S r obtained by dividing the Il product S2 by the cross-sectional area S1 of the M part of the metal strip that becomes the base 7', and calculate tfil
The ratio of the arc length of the groove after rolling pressure welding to the arc length of the cladding metal on the upper side where it is completely joined is taken as Qll, and the results of various studies are plotted. As is clear from this result, if the cross-sectional area S2 of the metal strip to be clad is smaller than 1.5 times the cross-sectional area S1 of the groove portion of the metal strip that becomes one slender metal, the metal strip will be clad with the side wall of one part of the vortex in the rolling direction. It can be seen that the bond between the two metals on the side wall of the groove where the relative slip amount is small is poor.

At 1.5 times or more than 1, the bonding is complete and the bonding performance is good, but at 1.9 times or more, the cladding metal strip overlaps the base metal, and the bonding border between the two becomes extremely wavy. Therefore, it is inappropriate.

場合にも本発明を適用し得ることは勿論である。In addition, although the case where one groove part is provided has been described above, it goes without saying that the present invention can also be applied to the case where two or more groove parts are provided and a plurality of metal strips are clad.
