| description | This molten iron alloy refining method is for refining a molten iron alloy while blowing oxygen to a molten iron alloy bath in a converter, wherein when a direct current is supplied between a first electrode disposed above the molten iron alloy bath and a second electrode disposed in contact with the molten iron alloy bath, at least one of formulas (1)-(4) is satisfied, where IP [A] represents the magnitude of the average of the direct current during a current passage period in which the current is passed, IP' [A] represents the magnitude of the average of the direct current during a current passage period within one minute immediately before the blowing of oxygen is stopped, Ws [t] represents the amount of molten steel in the converter, and As [m2] represents the area of the internal cross-section of the furnace at the belly thereof. (1): IP>=0.125*Ws. (2): IP>=1.5*As. (3): IP'>=0.125*Ws. (4): IP'>=1.5*As.
