Abstract
In a method of manufacturing metal powders in a continuous type, metal is heated at a temperature greater than a melting point to form a liquid phase metal, and the liquid phase metal and an emulsion carrier, which is emulsified without reacting with the liquid phase metal, are supplied into a container, and the liquid phase metal and the emulsion carrier are emulsified through Taylor flow to form an emulsion solution. The emulsion solution is discharged from the container, and then, the emulsion solution is cooled at a temperature smaller than the melting point to selectively solidifying the liquid phase metal in the emulsion solution to form the metal powders.
Claims5
A method of manufacturing metal powders, comprising:
- heating metal at a temperature greater than a melting point to form a liquid phase metal;
- continuously supplying the liquid phase metal and an emulsion carrier into a container, the emulsion carrier being emulsified without reacting with the liquid phase metal;
- emulsifying the liquid phase metal and the emulsion carrier through Taylor flow to form an emulsion;
- continuously discharging the emulsion from the container;
- and
- cooling the emulsion a temperature smaller than the melting point to selectively solidify the liquid phase metal in the emulsion to form the metal powders,
- wherein forming the emulsion comprises controlling a rotation velocity of a tumbling barrel mounted in the container in a range of 1,000 to 3,000 RPM to form a vortex of an annular pair arrangement having opposite directions to each other.
