When the water is jetted from the opening 6 onto the tapered surface 2 of the single roll 1, if the cooling ability of the tapered surface 2 is uniform in the width direction as in the conventional case, the molten metal carried away on the tapered surface 2 by the roll rotation is removed. Since the amount is constant per unit time, the amount of molten metal supplied per unit length in the rotation direction becomes small and the thickness becomes thin on the major axis side where the surface velocity due to rotation is large. However, in the method of the present invention, the cooling ability of the tapered surface 2 is improved by inclining from the short diameter side to the long diameter side. Therefore, solidification proceeds rapidly on the long diameter side, so that it is possible to make the thickness uniform in the width direction. it can.

である。In such a method of the present invention, the tapered surface 2
The cooling capacity is changed according to the thickness and composition of the rapidly solidified foil 9, the major axis a, the minor axis b of the single roll 1, the inclination angle β, and the rotation speed. At that time, the thickness of the high thermal conductivity material 17 forming the tapered surface 2 is in the range of 1 mm or more on the major axis a side and 0.5 mm or more and 10 mm or less on the minor axis b side. It is desirable to make it thicker than the b side. The lower limit of the thickness depends on processing restrictions, and the upper limit is because if the thickness b side exceeds 10 mm, the effect of adjusting the thickness of the foil 9 becomes difficult to be recognized.

ので、長径ａ側の厚さは４．５mm以下が望ましい。The thickness of the low thermal conductivity material 18 forming the tapered surface 2 is 0.1 mm or more and 5.0 mm or less on the minor axis b side and 4.5 mm or less on the major axis a side. It is desirable to make the major axis a side thinner than the minor axis b side. This is because the effect of adjusting the thickness of the foil 9 becomes difficult to be recognized when the minor axis b side is less than 0.1 mm, and the cooling rate difference becomes unclear when the minor axis b side exceeds 5.0 mm. When the thickness on the minor axis b side is 5.0 mm, the difference in thickness from the major axis a side is 0.
If the thickness is not about 5 mm, it is difficult to recognize the effect of adjusting the thickness of the foil 9, so the thickness on the major axis a side is preferably 4.5 mm or less.
