The purpose of the present invention is to provide: a refining method for efficiently operating a converter during converter refining, even without having equipment for spray-application of a dephosphorization agent; and a molten steel production method. In the refining method in which molten pig iron is refined by dephosphorization or by dephospherization and decarbonation, without spray-application of a dephosphorization agent on the molten pig iron, the dephosphorization agent containing at least a powder is introduced to a reaction container, then the molten pig iron is introduced to the reaction container and refined. |
