The method of manufacturing an iron-based powder with the molten steel are disclosed. The production method of the present iron-based powder according to the invention includes the step of water injection to the molten steel that is discharged through a nozzle connected to the stage, and the tundish to provide an iron-based steel produced through the iron making process and steel making process in the tundish . By preparing the iron-based powder by the present invention is applied to the molten iron in the iron making process chulseon from the molten steel was charged to a converter without the refining after the molten iron pretreatment process can economically provide a high degree of purity of the iron-based powder.
