Understanding the aggregation‐floating behavior of alumina inclusions, which is influenced by the interface properties between inclusions and molten steel, is crucial to controlling the purity of IF (interstitial‐free) steel in the refining process. This work attempts to investigate the effect of aluminum and titanium concentrations on the aggregation‐floating behavior of alumina inclusions in the interior of IF molten steel based on the interface properties between molten steel and alumina inclusions. The interface properties between the molten steel and alumina inclusions were measured using an improved sessile drop method. And the aggregation‐floating behavior of inclusions in the interior of molten steel has been quantitatively discussed by an aggregation model based on the attractive force between alumina inclusions, which was combined with the interface properties. The results show that the attractive forces between alumina inclusions, ranging from 6.96×10‐6 to 5.41×10‐5 N, increase and decrease, respectively, with increasing aluminum and titanium concentrations. Furthermore, the terminal floating speeds of alumina inclusions, ranging from 0.0510 to 0.0873 m/s, increase and decrease, respectively, with increasing aluminum and titanium concentrations.This article is protected by copyright.
