Through studying the varying pattern of inclusions in the first slab of ultra-low carbon steel produced by BOF-RH-CC process,it is concluded that the nitrogen content and T[O] obviously decrease with increasing casting length;generally,the quantity of micro and large inclusions decrease with the increase of casting length.The micro inclusions in the first slab are mainly Al2O3,TiN and Al2O3-TiN,and the large inclusions are mainly TiN,SiO2,Al2O3,K-containing aluminosilicate and Na-containing calciumaluminum.This study suggests that the inclusion quantity in the first slab of ultra-low carbon steel is closed to the level of normal slab at and after the length of 3.5 m.
