<p>PROBLEM TO BE SOLVED: To provide a method and a device for producing high-purity metal powder while preventing molten metal leakage from a nozzle in melting when powder is produced by atomization.SOLUTION: A seat having flexibility (compression stability) and having a melting point higher than that of a molten metal is provided in the surroundings of a molten metal nozzle projecting upward of a tap hole disposed on a melting pot bottom part. A molten metal stopper is pressed on a top part of the seat for preventing leakage of molten metal, and atomization powder can be stably produced.</p> |
