Behavior of Desulfurization in Ladle Steel Refining with Powder Injection at Reduced Pressures

Behavior of Desulfurization in Ladle Steel Refining with Powder Injection at Reduced Pressures

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 desulf...

Zusammenfassung: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.
