As shown in the figure, a polishing roll 5 rotating in a direction C opposite to the rotation direction B of the cooling roll 4 is brought into contact with the cooling roll 4 under a constant pressure, and the cooling roll 4 roughened by the injected molten alloy is removed. By polishing the circumferential surface and maintaining a constant surface condition on the circumferential surface of the cooling roll 4, a continuous, homogeneous amorphous alloy ribbon was manufactured (Amorphous Alloy, Its Physical Properties and Applications, Ken Masui, Fuka) (ed. Kazuaki Michi, Agne, published August 20, 1981).

響を及ぼすという欠点がある。In the conventional cooling roll polishing method for liquid quenching described above, it is extremely difficult to bring the rotating cooling roll and polishing roll into contact with a constant pressure because the cooling roll rotates at several thousand revolutions per minute. However, the disadvantage is that the polishing equipment becomes complicated and requires not only a large investment but also a large amount of effort to adjust the equipment6.Furthermore, the polishing roll is a consumable item.
Polished roll materials with fine grains are expensive and have the disadvantage of affecting the product price.

The peripheral surface of the cooling roll is polished by pressing the free surface side of the phosphor bronze plate (filed under Patent Condylar Intercondylar 61-12385) using the spring properties of the phosphor bronze plate. shall be.
