Evolution Behavior and Refinement Mechanism of Inclusion by Magnesium Treatment in Al-Killed Steel




1st Paragraph: In recent years, steel liquid by magnesium treatment is attracting more and more attention. It pointed out that the inclusion of steel liquid after magnesium treatment is refined[1-3]. The evolution of inclusions after magnesium treatment in different steel grades were reported[2, 4-7], however the refine-control mechanism is still in controversy. In the present study, the melts containing aluminum were prepared. After addition of magnesium, the samples extracted at different time were analyzed by scanning electron microscopy. The composition and three-dimensional morphology of inclusions in the samples were investigated.
