Document Type and Number:
Japanese Patent JP6855054
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an Fe-Si-B based rapid-solidified alloy thin strip excellent in mass productivity and capable of easily realizing the making of a thick plate at a low cost.SOLUTION: Provided is a method for producing an Fe-Si-B based rapid-solidified alloy thin strip with the average thickness of 40 μm or higher by jetting an Fe-Si-B based alloy molten metal to the surface of a cooling roll using a tap nozzle whose bottom part is disposed with a multi-orifice. The multi-orifice being a staggered type multi-orifice in which the central spacing E of the respective orifices in orifice lines is 2 to 10 mm, and the off-set angle θ of the adjacent two orifice lines is 20 to 80°.SELECTED DRAWING: Figure 1
