摘要：
Before deoxidation, the main inclusions were Fe-Mn-O inclusions in Ti-bearing ultra low-carbon steel melt. After 3 min Al addition, the inclusions changed to be granular and spherical Al2O3 center dot Al2O3 cluster, composed of granular and spherical particles with diameter 1-2 mu m, formed in 7 to 10 min after Al addition into the melt. Al2O3 center dot TiOx inclusions with the Ti/(Al+Ti) between 0.15 and 0.30 formed 3 min after ferro-titanium addition and Al2O3 center dot TiOx cluster formed because rich [Ti] and poor [Al] regions existed around the ferro-titanium particles and Al2O3 cluster. The Ti3O5 was hard to be formed when acid-soluble aluminum exceeded 0.035% with titanium blow 0.08%. The activity of Ti3O5 in the complex liquid phase inclusions increased remarkably with the decrease of acid-soluble aluminum and increase of titanium.
