Patent number: 11920205Abstract: The present invention provides a casting method and cast product of spherical graphite cast iron, in which, even with a small modulus, there is no chill, the spherical graphite in the tissue is further made ultrafine, the dispersion of the particle diameter is small, and the number of the particles is several times that of the conventional one in the as cast state where heat treatment is not carried out. A casting method of a spherical graphite cast iron includes a melting process, a spheroidizing treatment process, an inoculation process, and a casting process, in which the original molten metal after the inoculation process is poured and filled up to a product space through a gate of a metal mold; where the original molten metal is controlled to a semi-solidification temperature range, before being filled up to the product space.Type: GrantFiled: May 23, 2022Date of Patent: March 5, 2024Inventors: Masayuki Itamura, Haruki Itofuji, Mitsuru Adachi
