Abstract

A mathematical model of sulfide precipitation on oxides during solidification is established based on the coupled model of microsegregation and inclusion precipitation, which is also established by the present authors.1) In this paper, sulfide capacity and optical basicity are introduced to calculate the distribution of sulfur between liquid oxides and molten steel during solidification, and the effect of composition of oxides on the precipitation of sulfide is also discussed. The calculated results agree well with the experiment results and data reported.
