Abstract: A method of manufacturing iron-based powder includes providing an iron-based molten steel manufactured through a iron making process and a steelmaking process to a tundish; and performing water atomization over the molten steel discharged through a nozzle connected to the tundish. The iron-based powder is manufactured from the molten steel refined after a molten iron tapped from a iron making process is charged into a converter without a pre-treatment process of the molten iron, thus economically providing the highly clean iron-based powder.

Abstract: A metal powder manufacturing device for manufacturing a metal powder includes a feed for supplying a molten metal, a fluid spout unit, and a course modification unit. The fluid spout unit further includes a channel and an orifice. The channel is provided below the feed, allowing passing of the molten metal supplied from the feed. The orifice is opened at a bottom end of the channel, spouting a fluid into the channel. The above course modification unit is provided below the fluid spout unit, and forcibly changes the traveling direction of a dispersion liquid. This dispersion liquid is composed of multiple fine droplets dispersed into the fluid. The above droplets are a resultant of a breakup caused by a contact between the molten metal and the fluid ejected from the orifice. Here, the dispersion liquid is transported so that the droplets is cooled and solidified in the dispersion liquid in order to manufacture the metal powder.

Abstract: A process for producing a magnetic powder which is sufficiently reduced in core losses such as iron loss and hysteresis loss and has sufficient strength; and a process for producing a dust core. The process for magnetic powder production comprises using a magnetic-material powder produced by water atomization as a raw powder and subjecting the powder to spheroidizing in which a mechanical impact is applied to the powder to spheroidize the powder particles. After the spheroidizing, the powder is subjected to a grain enlarging treatment in which the powder is annealed at a temperature not lower than the austenite transformation point. The process for dust core production comprises compacting the magnetic powder thus produced.
