Title: Production of metal powder
Inventor: SUGIHARA YUTAKA
IPC: B22F9/08
Filed: 1990-11-30
Abstract: PURPOSE:To easily control the powder characteristics, such as grain size and apparent density, of a produced metal powder by regulating the liquid level height of molten metal in a tundish at the time of allowing the molten metal in the tundish to fall down into a spray tank and pulverizing this molten metal by means of high pressure water. CONSTITUTION:A molten metal 2 in a ladle 4 is allowed to fall down through a sliding nozzle 6 into a tundish 8 and further fall in the form of a molten metal flow 16 through a bottom nozzle 14 into a spray tank 18 and high pressure water is sprayed through a high pressure nozzle 22 to pulverize this molten metal, by which a metal powder is produced. At this time, the pressure and amount of the high pressure water and the bore diameter of the bottom nozzle 14 are held constant, respectively, and the liquid level height of the molten metal in the tundish 8 is detected by means of a liquid level detector 10 or a load cell 12, and the flow rate of the falling molten metal is controlled by regulating the above liquid level height. By this method, the ratio of the flow rate of the high pressure water to the flow rate of the molten metal can be regulated, and the powder characteristics, such as grain size and apparent density, of the resulting metal powder can be controlled.
