Abstract

Based on thermodynamic calculation analysis the inclusions and thermodynamics of X80 before and after calcium treatment on the sample of a steel production Results show that the effect of Al2O3 inclusions degeneration is good and S would exist in a dissolved state so that avoids the CaS inclusion precipitation when the [Als] is 0.04% [O] is adjusted to 0.7×10-4%~18×10-4% [Ca] is adjusted to 6×10-4%~24×10-4% in the meanwhile control of [S] below 0.009% at 1873K Al2O3 inclusions in steel is effectively modified into calcium aluminate the number and the size of inclusions were reduced most of them below 5 m and the shape more regular.
