Patent ID: 8602086

Claim:
A method for producing an amorphous alloy foil strip, comprising: a first process of supplying a molten alloy to a first cooling zone while rotating a cooling roll, the first cooling zone forming a part of an outer circumferential portion of the cooling roll and extending along a circumferential direction of the cooling roll; and a second process of supplying the molten alloy to a second cooling zone while rotating the cooling roll, the second cooling zone forming other part of the outer circumferential portion of the cooling roll, the second cooling zone being separated from the first cooling zone in an axial direction of the cooling roll with a heat-insulating zone interposed between the first cooling zone and the second cooling zone such that the outer circumferential surfaces of the first cooling zone, the second cooling zone and the heat-insulating zone form a continuous surface of the cooling roll, wherein the heat-insulating zone is made of a material different than the material forming the first and second cooling zones, the first process and the second process being alternately executed.
