Based on the experiment of adding rare earth into interstitial free(IF) steel of Baotou Steel, the changes of cleanliness of IF liquid steel were studied. The results showed that no rare earth oxides were found in the slag when steel ladle left RH. CeO and Ce2O3 were found in the slag during casting as well as the valence states were + 2 and + 3. The effects on oxidability and Ca-Al rate in slag were not great with and without adding rare earth. The content of TFe in tundish is about 5% and CaO/Al2O3 is stabilized at about 1.3. The size of Al2O3 along the thickness direction of casting blank for the heats without adding rare earth is larger and increases from inner and outer arc to the center of casting blank as well as it decreases and the quantity of Al2O3 increases after add rare earth.
