2. 1. Formation of oxide-inclusions by ladle glaze and a preliminary examination on the possibility of inclusion seperation by bubble floatation

   Author : Nagendra Tripathi; KTH; []
   Keywords : oxide inclusions; ladle metallurgy; ladle glaze; inclusion population; ladle age;

   Abstract : The present work was to study the role of ladle glaze as apotential supplier of inclusions to the steel melt during theladle refining process. In this study, the total number ofinclusions at the beginning and at the end of the ladletreatment process was found to be increasing with ladle age,which is the number of heats, the ladle being used.
