摘要：
PROBLEM TO BE SOLVED: To provide a practical process for producing a pig iron which can be used for manufacturing various types of steel having high quality, while using a variety of iron scrap as an iron source.
SOLUTION: The method for producing molten pig iron includes the steps of: producing molten pig iron containing carbon by using the iron scrap as the iron source, in an arc furnace; mixing the molten pig iron with molten pig iron produced in a blast furnace; and desulfurizing the mixed molten pig iron. In this case, it is preferable to further dephosphorize the molten pig iron after the desulfurizing treatment, and to control the carbon concentration of the molten pig iron to be produced in the arc furnace to 1.5 mass% or more.
