Latest Patents

Hideharu Nakano holds a patent for an "Additive for use in producing spheroidal graphite cast iron." This invention involves an additive that contains fine particles of magnesium oxide with a purity of 90 weight % or more. The additive also includes at least one component selected from a group consisting of a graphite-spheroidizing material, an inoculant, and a graphite-spheroidizing inoculant. The use of highly pure magnesium oxide increases the number of nuclei in a melt, resulting in a higher graphite spheroid count in the produced spheroidal graphite cast iron. Additionally, another aspect of his patent includes an oxide of a metal that has a lower affinity for oxygen than the graphite-spheroidizing element used in the treatment. This innovation allows for the dispersion of fine oxide particles, enhancing the quality of the spheroidal graphite cast iron.
