    摘要： In the continuous manufacturing of metal strip from molten alloy, the nozzle from which the melt issues to form the continuous strip by rapid-cooling solidification has an orifice that is discontinuous in the width direction of the strip; i.e., it is a multiple orifice. This enables amorphous and crystalline continuous metal strip to be produced in much greater widths than has hitherto been possible, and the strip thus produced is more uniform in thickness.

    摘要： According to the present invention, in the PFC (planar flow casting) method, He gas at room temperature is blown onto the surface of a cooling roll at a flow rate of 0.1 to 5 liters/min.multidot.cm.sup.2 through a He gas blow nozzle provided upstream of a molten alloy (a puddle) ejected through a molten alloy ejection nozzle onto the surface of the cooling roll at a distance from the ejection nozzle, the distance from the surface of the cooling roll and an angle of inclination of the nozzle within respectively specified ranges, thereby forming a He gas atmosphere around the puddle, and a thin strip is dragged out of said puddle. This enables a thin amorphous alloy strip having a very small thickness and a smooth surface free from significant uneven portions and pores to be easily produced at a low cost without use of any vessel for regulating the atmosphere or an apparatus for heating the blown gas.
