  The effects of the addition of the corresponding stoichiometric amount of rare earth elements (RE) in relation to the amount of sulfur (S) in cast iron melts with different carbon equivalent (CE) and the addition of inoculants such as Ca-Si and Fe-Si on the chilling tendencies and mechanical properties of flake graphite cast iron were investigated. The addition of the corresponding amount of about 0.2%RE, in relation to the amount of 0.08%S in the melt, was found to reduce the chilling tendency markedly. The effects of RE on the chilling tendency and tensile strength were found to improve the most in the low CE specimen and the least in the high CE specimen. When RE and Ca-Si as were added a post-inoculant to the melt with 3.4%CE, a tensile strength of 320MPa and Brinell hardness of 190 were obtained with a chill depth of 3mm.
