Method for producing Fe-based amorphous alloy ribbon, apparatus for producing Fe-based amorphous alloy ribbon, and wound body of Fe-based amorphous alloy ribbon

摘要

Fe-based amorphous alloy ribbon by forming a coating film of molten alloy on the outer circumferential surface of the cooling roll after polishing by the polishing brush roll, cooling the coating film on the outer circumferential surface, and winding the Fe-based amorphous alloy ribbon peeled off by a peeling means with a winding roll. A method for producing an Fe-based amorphous alloy ribbon to obtain a wound body of the present invention, comprising: a polishing brush having a roll shaft member and a plurality of brush bristles as the polishing brush roll, satisfying conditions (1) and (2), and Is a method for producing an Fe-based amorphous alloy ribbon having an abrasive brush roll axially rotated in the opposite direction. (1) More than 30 mm free length of brush brim (2 mm or less) (2) Density of brush brim at brush brim end 0.30 / mm2 or more 0.60 pieces / mm2 or less
