Abstract
A method and apparatus are provided for producing an amorphous ribbon by ejecting and rapidly solidifying molten alloy on a circumferential surface of a rapidly rotating cooling roll, wherein the cooling roll is polished online during amorphous ribbon production. When the circumferential surface of the cooling roll after peeling off the ribbon is polished using a polishing member, the circumferential surface of the cooling roll is polished continuously or intermittently across its lateral direction while differentiating the polishing mode in accordance with the surface properties.
Claims13
A method for producing an amorphous ribbon by ejecting and rapidly solidifying molten alloy on a circumferential surface of a rapidly rotating cooling roll, which method comprises:
- in the course of the ribbon production, using a polishing member to polish a circumferential surface of the cooling roll from which the ribbon has been peeled;
- and
- during the polishing, conducting continuous or intermittent polishing across the lateral direction of the circumferential surface of the cooling roll while differentiating the polishing mode in accordance with the surface properties.
An apparatus for producing an amorphous ribbon by ejecting and rapidly solidifying molten alloy on a circumferential surface of a rapidly rotating cooling roll, which apparatus comprises:
- a polishing member installed on the cooling roll outer periphery between a produced ribbon peeling location and a molten metal ejecting location, which polishing member is differentiated in polishing mode in the lateral direction of the cooling roll.
