Daido Steel Shibukawa Plant has developed the iron removal method from Ni-based molten metal.The results obtained in the running operation are summarized as follows, (1) Decreasing of activity of FeO by low basicity operation(2) Removal of Mn by O2 enrich operation(3) Increasing of activity of MnO by MnO addition[Fe] in Ni-based molten metal has been removed under 0.30% by these operations in the electric arc furnace.Monel 400 and Nickel 200 ([Fe]<0.30%) are melted in EAF-VLF process without the contaminations of iron from EAF.
