PURPOSE:To improve the productivity of a metal fine wire by arranging narrow tube part in between a crucible for molten metal and an injection nozzle for molten metal, heating and injecting molten metal jet into cooling liquid layer on inner circumferential face of a drum. CONSTITUTION:The narrow tube part 40 is arranged at lower end of the crucible 28 for molten metal and the nozzle 30 for molten metal is formed at tip part thereof. An induction coil 26 is arranged at outer side of the crucible 28 and an electric heating wire 42 is arranged at out of the narrow tube 40. By rotating the drum 10 at high speed, the cooling liquid layer 24 is formed in the inner circumferential face of the drum 10 and the high frequency current is conducted to the induction coil 26, to melt the base alloy in the crucible 28. Successively, the crucible 28 is inserted into the drum 10 and the pressurized molten alloy is injected into the cooling liquid layer from the nozzle 30. As contact of the coil 26 with the liquid layer 24 and clogging of the nozzle 30 are prevented, the injection of large quantity of base alloy at one time can be executed. Therefore, the productivity of the metal fine wire is improved. |
