Zusammenfassung:	PURPOSE:To economically and efficiently produce molten Ni-containing iron by charging the molten iron into a smelting reduction furnace and charging nickel ore, nickel-containing high alumina material and carbonaceous material while blowing oxygen from a top blowing oxygen lance. CONSTITUTION:The molten iron is charged into the smelting reduction furnace 1. Successively, while blowing the oxygen on the surface of the molten iron from the top blowing oxygen lance 2, the nickel ore and the nickel-containing high alumina material as the nickel source are continuously charged from a raw material hopper 5 and also the carbonaceous material of coke, etc., is continuously charged. The charge of the above nickel source can be executed by dividing into two steps of the charge of the nickel ore and the carbonaceous material and the charge of the nickel-containing high alumina material and the carbonaceous material. Further, the content of the nickel-containing high alumina material in the nickel source is desirably
