Abstract
A method and apparatus for manufacturing an amorphous metal ribbon provides the following: jetting a molten metal from a nozzle, which has a slit-shaped opening, to a cooling roll, which rotates at a high speed, so as to form a puddle on the cooling roll; and spreading the puddle for rapid solidification. Additionally, the present invention provides at a position upstream from the puddle in a direction opposite the direction of rotation of the cooling roll, cleaning the surface of the cooling roll by blowing carbon dioxide gas to which ultrasonic vibration is applied.
