To provide a practical device, promoting smooth atomization of molten metal by preventing the molten metal from adhering to the inner surface of a molten metal nozzle part of a gas atomizing nozzle to cause coagulation during the atomization of molten metal in a metal melting and atomizing apparatus adapted to spray molten metal levitated and molten in a levitation melting furnace from a gas atomize nozzle fitted to the base of the furnace body of the levitation melting furnace.

The gas atomize nozzle 21 fitted to the base of the furnace body of the levitation melting furnace is composed of a gas atomize nozzle 21, a tapping nozzle 31 and a gas atomize nozzle 41. These nozzles are formed of two or more segments 12, 32, 42 made of water cooled copper, insulated from each other, and erected substantially cylindrical. A molten metal nozzle part 51 is formed by surrounding with these segments made of water cooled copper, a heat insulation layer 61 made of fireproof material is formed at least on the inner surface of the lower part connected to the molten metal nozzle part out of the whole inner surface of the molten metal nozzle part and the inner surface of the molten metal nozzle, and a high-frequency induction heating coil 71 is disposed in the outer periphery of at least part surrounding the heat insulation layer in the gas atomize nozzle.
