Abstract Scope |
The effect of cerium content on inclusions in Si-Mn killed stainless steels was studied at 1873 K using laboratory experiments. It was found that when the T.Ce content increased from 0 to 430 ppm, the area fraction and number density of inclusions in the steel increased and the appropriate addition of Ce could refine the size of inclusions. With the increase of T.Ce content in the steel, inclusions were modified into Ce-containing ones. The transformation sequence was: Al-Si-Mn-Ca-O → Ce-Al-Si-Mn-Ca-O → Ce-O-S. The experiment result was consistent with the thermodynamic analysis. |
