Behavior of desulfurization in ladle steel refining with powder injection at reduced pressures

Abstract

The present work experimented with ladle desulfurization by powder injection under reduced pressure in comparison with under atmospheric pressure. It was found that powder injection under reduced pressure provides a high stirring force, activates the entrapment of top slag and accelerates the desulfurization reaction involved. © 1989, The Iron and Steel Institute of Japan.
