摘要： PROBLEM TO BE SOLVED: To provide a method by which decarburization of molten iron at a dephosphorizing treatment can efficiently be restrained and further, the molten iron is efficiently dephosphorized by using CaO-based flux for dephosphorization even without using fluorine, such as fluorite, as a flux.
SOLUTION: In a dephosphorizing method for supplying a gaseous oxygen source into molten iron, the dephosphorization is performed by using carbon dioxide gas as a part of the gaseous oxygen source, wherein the concentration ratio of the carbon dioxide gas in the gaseous oxygen source is changed during the dephosphorizing treatment so as to increase, that is, the concentration of the carbon dioxide gas in the gaseous oxygen source is set to 10-30vol% at the initial stage of the dephosphorizing treatment and to 50-100vol% at the end stage of this treatment. Further, the decarburization in the molten iron can efficiently be restrained without obstructing the dephosphorizing reaction by reducing in advance silicon content to ≤0.1 mass% before the dephosphorizing treatment of the molten iron. In this case, the fluorine source is unnecessary to be used as the flux by blasting the flux 18 for dephosphorization mainly containing CaO together with the gaseous oxygen source toward the molten iron surface.
