Use of Synthetic Slags to Control the Level of Inclusions in Steels (Room 411)

In this work, a methodology is proposed to measure the inclusion removal efficiency from steels using synthetic slags. The slags studied in the laboratory test were similar to those applied in industrial processes of steel refining. For each experiment, about 300 g of steel was melted into an MgO-C crucible, and after 5 minutes synthetic slag was added on the melted steel. After 5 more minutes, the crucible was cooled in the natural environment, and the level of inclusions before and after the experiment were compared. Some correlations were proposed to evaluate the ability of slags to remove inclusions.
