COOLING ROLLER AND MANUFACTURING DEVICE FOR AMORPHOUS ALLOY FOIL STRIPS

摘要

This cooling roller (11) is characterized in that flow passages (21a, 21b, 21c), which pass through side surfaces of the cooling roller along the direction of a rotating shaft of the cooling roller, are arranged equidistantly on at least two concentric circles centered on the rotating shaft. This manufacturing device (2) for amorphous alloy foil strips is characterized by comprising the cooling roller (11). It is thus possible to manufacture thick amorphous alloy foil strips on an industrial scale.
