Abstract
A method of producing iron powder by a water atomization process may include preparing a molten metal in a tundish, discharging the molten metal in a free-falling manner by opening an orifice formed on a bottom of the tundish, and producing iron powder by spraying water onto the free-falling molten metal using a pair of water spraying nozzles, an angle formed by the water spraying nozzles being at least 45°.
