Abstract：According to the production process of HP295 steel by LD-BAr-CC, the evolution of the non-metallic inclusions and the cleanness level during the whole process are systematically investigated and analyzed， emphasizingtype, quantity and distribution of inclusions in slab. Through investigation,the rule of their variation is found out, the control level of inclusions is determinedand some measures are put forward for improving the cleanliness of HP295 steel.
