More Information
Summary:A spray nozzle according to the present disclosure includes a spray nozzle holder protruding toward the inside of a chamber and a spray nozzle tip coupled to the spray nozzle holder, wherein the spray nozzle tip is oriented toward a direction lower than the spray nozzle holder, so that the pressure of cooling water can be efficiently transmitted to molten metal droplets that are atomized and scattered, resulting in a fast cooling rate. Thus, the present disclosure is advantageous in the manufacture of metal powders with a high amorphous phase ratio. In addition, by controlling a spray angle and a spray coverage angle of the spray nozzle tip, it is possible to consistently manufacture metal powder under various cooling conditions, thereby obtaining favorable conditions for the manufacture of amorphous metal powder, and thus increasing the ratio of the amorphous phase of the manufactured metal powder.
