| Résumé | In this study, desulfurization from liquid iron by Ar and (10 to 40 pct)H-2 + Ar plasma arc melting (HPAM) was examined. The experimental results show that the rate of desulfurization increases as hydrogen is added proportionally to plasma gas. The thermodynamic analysis suggests that the interaction of activated atomic hydrogen and dissolved sulfur in liquid iron, [S] + 2H = H2S; could be taking place. The kinetic analysis confirms that the desulfurization from liquid iron obeys a first-order rate law. (C) The Minerals, Metals & Materials Society and ASM International 2018 |
