Abstract: Non-metallic inclusions in molten steel mainly originate from refractory-slag-steel interactions during continuous casting and influence its cleanliness remarkably. The objective of this paper was to apply a new approach of minimising non-metallic inclusions by interaction with a suitable MgO-C-based lining material. With the purpose of investigating the efficiency of MgO-C and MgO-CMA-C to reduce endogenous inclusions, immersion tests were performed in a metal casting simulator at 1650 °C. Investigations of the inclusions were carried out by a special automatic SEM.
