PURPOSE:To obtain a metallic wire which decreases fluctuation in the wire diameter in the stage of spinning and producing the metallic wire from a molten metal by impressing a directional magnetic field to the molten metal flow in the position where the solidification of the molten metal ejected from a spinning port is not completed. CONSTITUTION:A molten metal 12 melted by a heater 13 in a crucible 11 is pressurized by an inert gas supplied through an introducing port 11a and is ejected as molten metal flow 14 from a nozzle 11b by which a metallic wire is produced. A directional magnetic field is impressed to the molten metal flow 14 by a means 15 for generating the magnetic field in the position where the flow 14 is not solidified yet to increase the apparent viscosity of the flow 14 and to suppress the oscillation of the surface tension wave. The jet flow of the molten metal is thus stabilized and the metallic wire which decreases the fluctuation in the wire diameter is obtd. |
