Abstract
A metal powder producing apparatus comprising a melted metal supplying part discharging a melted metal, a cylinder body provided below the melted metal supplying part, and a cooling liquid layer forming part forming a flow of a cooling liquid for cooling the melted metal discharged from the melted metal supplying part along an inner circumference face of the cylinder body, wherein the cooling liquid layer forming part has a primary pressure reservoir, and the primary pressure reservoir is provided on an outer circumference part of the cylinder body.
Claims6
A method of producing a metal powder comprising steps of
- forming a flow of a cooling liquid along an inner circumference face of a cylinder body that is below a melted metal supplying part in an up-downward direction, and
- discharging a melted metal from the melted metal supplying part to interact with the flow of the cooling liquid, wherein:
- a primary pressure reservoir for the cooling liquid is (i) on an exterior of the cylindrical body and (ii) has an outlet for the cooling liquid;
- the cooling liquid is supplied to the primary pressure reservoir below the outlet;
- the cooling liquid flows upward in the primary pressure reservoir to the outlet after being supplied to the primary pressure reservoir;
- and
- the cooling liquid flow is directed to make a U-turn from an upward direction in the primary pressure reservoir to a downward direction to flow along the inner circumference face of the cylinder body.
