Original researches on the refining method of cast iron by the electrolysis of slag will be described in this paper. Cast iron is not so easily reduced as steel that strong deoxidizing reagents, such as alkali, alkali earth metals and Mg, are necessary to reduce cast iron melts satisfactorily. Charging positive voltage to slag and negative voltage to melt, the electrolysis was made of slag which covered the surface of cast iron melt ; then, the melt could be reduced, resulting in the nodular graphite structure. The electrolysis was performed for 10〜30 minutes at 1, 250℃〜1, 350℃. Slag such as fluorides, chlorides, carbonates, oxides of alkali, alkali earth metals or Mg, seem to be applicable to the refining method.
