Abstract:
The present invention provides a power manufacturing apparatus capable of preventing particle growth when fine powder is formed through a fluid, the apparatus comprising: a molten steel providing part for providing molten steel; and a cooling fluid spraying part which is arranged at a lower part of the molten steel providing part and sprays a cooling fluid on the molten steel in order to pulverize the molten steel provided by the molten steel providing part, wherein the cooling fluid spraying part forms a first flow for cooling the molten steel so as to pulverize the molten steel and a second flow for forming a descending air current in the molten steel.
