Abstract Scope |
Inclusions in IF steel slab were detected to investigate the distribution of inclusions in Slab under the nozzle clogging state. The endogenous inclusions in IF steel were Al2O3 inclusions, TiN inclusions were precipitated with Al2O3 as the core during the cooling process of slab. In the thickness direction from the surface to the center of the slab, the area fraction of inclusions increased from 25.32 ppm to 267.78 ppm, the maximum value of inclusion area fraction was 405.62 ppm below the center of the slab. Due to the small cooling rate at the center of the slab, the number density of TiN larger than 10um reached 1.64 #/mm2. Under the condition of nozzle clogging, the level fluctuation is large in the mold, contrary to the normal condition, the number density of inclusions on the loose side of the slab was larger than the fixed side. |
