Abstract
  To make clear the merit of pig iron used in melting by low frequency induction furnace, influences of the kind of pig iron and its charge time on melting were examined. The later the pig iron was charged into the molten steel scrap, the better was the property of cast iron. This seems to be the result of improved freezing manner of the steel due to the suspended carbon from the pig iron in the molten steel scrap. The properties of cast iron were dependent on the kind of pig iron, and some properties were much influenced by the charge time of pig iron. The properties of cast iron combined with pig iron to make ductile cast iron were remarkable and the graphite in the pig iron, especially the ratio of graphitization contributed to this improvement.
