Assessment of Inclusion Removal Ability in Refining Slags Containing Ce2O3

The elimination of inclusions in steelmaking processes has been widely studied. removal by slags containing the rare earth oxide Ce2O3 are studied using an integrated numerical model. model involves inclusion motion model, interfacial tension calculation surface slag, and mass action concentration based on ion molecule coexistence theory. behaviors both solid Al2O3 50%wtAl2O3–50%wtCaO liquid varied sizes at CaO-Ce2O3-SiO2-Al2O3(-MgO) slag systems evaluated. results show that it is more difficult to remove with smaller a higher viscosity. Liquid than inclusions. It found CaO-Ce2O3-SiO2-Al2O3-MgO refining shows better ability CaO-SiO2-Al2O3-MgO slag. reason for this addition can decrease viscosity slags, as well improving wetting effects For two systems, system CaO-Ce2O3-SiO2-Al2O3 system. 5% 8% optimized case industrial applications.
