  The effects of sulfur and silicon on inter-graphite spacing λ in gray cast iron has been investigated by unidirectional solidification with Bridgman method. Sulfur content was varied from 0.004 to 0.108mass%, and silicon content was varied from 0.068 to 1.10mass%. The speed of crucible V was varied from 0.00015 to 0.01000cm/s. The temperature gradient at solid-liquid interface was 18∼21K/cm. The experimental equations of λ-V were obtained by using linear regression analysis. It was clarified that the transition from flake to undercooled graphite shifted differently according to sulfur and silicon content.
