Abstract：The article introduces the morphology and source characteristics of inclusions in cold-rolled ultra-low carbon steel billets of wide and thick plates at Benxi Iron and Steel. Based on the actual situation that mainly affects the inclusions in the billets during casting， the formation reasons and influencing factors of slag inclusions in the billets are analyzed， and corresponding operational and process improvement measures are proposed to improve the problem of inclusions in ultra-low carbon steel billets to a certain extent.

Key words： ultra low carbon；wide slab；inclusion；improve measure
