摘要： 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.

摘要： A metal powder production apparatus is capable of efficiently producing fine metal powder with a uniform particle size. The metal powder produced by the apparatus has an increased quality. The apparatus (atomizer) makes use of an atomizing method to pulverize molten metal into metal powder. The apparatus includes a supply part (tundish) for supplying the molten metal, a nozzle provided below the supply part, a tubular member provided between the supply part and the nozzle. The tubular member is constructed to ensure that the molten metal ejected from an ejection port passes through a bore of the tubular member and then makes contact with a fluid jet. Further, the tubular member has a top end air-tightly connected to the supply part and a bottom end lying around the midway of a first flow path through which the molten metal passes.

摘要： In sintering a metal powder after pressure molding into a given configuration, random amorphous flaky metal fine powders (10) are used as metal powder materials. In addition, spherical particulate metal powders 11 are used as main materials, and random amorphous flaky metal fine powders 10 having finer particle size than the metal powders 11 and produced by fracturing a metal fracture material by means of high-velocity gas swirling flow are used as sub-materials, and molding and sintering are performed in a state of dispersing the sub-materials (10) in the main materials (11). Thus, despite being a power metallurgical product, it is possible to obtain a metal product having a dense metallographic structure and excellent in properties such as mechanical strength.
