(S017-1)The Formation of Non-Metallic Inclusions by Ladle Glaze and the Effect of Slag on Inclusion Composition Using Tracer Experiments

摘要

Inclusions can be formed either endogenously, e.g. by deoxidation, or exogenously, e.g. from slag and refractory lining. Recently, more and more attention has been drawn to the role of ladle glaze as a source of non-metallic inclusions in molten steel. These studies suggest that ladle glaze is one of the major sources of inclusions during the ladle refining process. The effect of ladle slag on the inclusions has also been a topic of many research groups. On the other hand, how fast the slag affect the inclusions and the detailed mechanism of the effect are still not fully understood.
