PROBLEM TO BE SOLVED: To provide a desulfurization processing method of a molten iron improving desulfurization efficiency by reducing generation of CaO-AlO-based solid solution.SOLUTION: The desulfurization processing method of a molten iron is conducted by desulfurizing the molten iron 2 containing C (carbon) of 2 to 5 mass% in a device for receiving iron 3 at 1250°C or higher. The desulfurization processing method is conducted by adding a desulfurizing agent 100, obtained by adding 2 mass% or more of an aluminum mixture containing a metal Al (aluminum) at percentage of 85 mass% or more to CaO (calcined lime), to the molten iron 2 agitated by a mechanical impeller 11 in the device for receiving iron 3. |
