Abstract：Through the analysis of cleanliness， unsteady casting of DC06 steel in the production process the results show that the head slab 2.5 m after inclusion content of casting billet tends to be stable， close to the 3.0 mg/10 kg normal level is higher than the level of normal slab billet; large inclusion content transfer blank， mainly containing Ti and Zr of the Al2O3-CaO class with content level; the fluctuation of the large inclusions in the slab， close to the normal level of billet; nozzle change when the large inclusions in the slab billet was significantly higher than the normal level， reached more than 20mg/kg， the inclusions are mainly spherical alumina inclusion， source water mouth clogging.
