Abstract: PURPOSE:To efficiently and stably micronize a molten metal to a uniform particle size by ejecting a jet along the inverse conical curved surface of the peripheral side face of a melt nozzle and allowing the melt to flow radially on the nozzle tip face by the ascending flow of the atomizing gas. CONSTITUTION:A molten metal is dropped from the nozzle hole 10 of a nozzle 3 fixed to the bottom of a tundish contg. the molten metal. A high-pressure gas introduced into the annular gas chamber 5 in the nozzle main body 2 surrounding the nozzle 3 is ejected from a slit gas nozzle 11 as a jet 12. The molten metal is powdered by the jet 12. In this spray nozzle device for powdering the molten metal current by the jet 12, the jet 12 is ejected along the inverse conical peripheral side face 8 at the tip 7 of the nozzle 3. Consequently, the ascending flow 14 of the atomizing gas is generated at the intersection 13 of the jets, and a radial molten metal current 15 is formed on the tip face 9 of the nozzle 3. The molten metal current is collided with the jet 12 at the periphery of the tip face 9 and powdered, and the nozzle hole 10 is never clogged.
