Abstract

PURPOSE:To easily obtain quickly solidified powder with simple equipment by increasing the velocity of the cooling liquid flow obtd. by injecting the ejected flow of a molten metal into the cooling liquid flow before the molten metal solidifies, thereby parting and grinding the molten metal in the cooling liquid flow. CONSTITUTION:The flow 4 of the molten metal consisting of an Al (alloy), etc., is injected at a velocity higher than the velocity of the cooling liquid flow 2 of water, etc., injected from a nozzle 1 into the liquid flow 2. The cooling liquid flow 2a contg. the molten metal flow 4 is then fed from a receiving mouth piece 7 through a recovering pipe 8 to a powder recovering tank 9. A suction pump 10 is connected to the recovering pipe 8 in this case to increase the velocity of the cooling liquid flow 2a contg. the molten metal 4 flowing into the receiving mouth piece 7 and to part and grind the molten metal flow 4. The metal powder obtd. in such a manner has better powder moldability than the powder moldability of the metal powder produced by the conventional rotary drum method.
