Abstract
PURPOSE:To obtain metal powder having uniform particle size at high yield by proportionally controlling pulverizing force of gas for atomizing in accordance with variation of molten metal head in a tundish. CONSTITUTION:At the time of producing the metal powder by injecting N2 gas as the gas for atomizing against the molten metal flow dropping from the tundish 1, the variation of weight of the tundish 1 during the operation is continuously measured with a loading meter 3 of load cell, etc., and the measured value is inputted in the arithmetic and control unit 4 to calculate the dropping flow rate of the molten metal. Based on command of the control unit 4 using the variation rate of the measured values as a correction factor, a pressure control valve 5 in the above N2 gas supplying line (l) is proportionally controlled to fix the pressure and flow rate (pulverizing force) of the N2 gas per unit molten metal wt. applied to the molten metal flowing down stream from nozzles 2, 2'. By this method, the metal powder having uniform particle size can be obtd. at high yield.
