Constitutional Segregation of Al2O3 in Mold Slag and Its Impact on Steel Cleanliness During Continuous Casting
The alumina pickup in a range of mold fluxes used for continuous casting of aluminum (Al)-killed ultralow carbon, low carbon, and peritectic steel have been measured. The Al 2 O 3 pickup in slag varies approximately from 7 to 12 pct and depends on the slag basicity. Significantly higher Al 2 O 3 pic...
