Abstract

The stabilization of refining slags in ladle treatment with alumina fluxes is studied. In refining, the slag is stabilized in the presence of alumina fluxes thanks to isomorphic replacement of a calcium ion by alkali-metal ions and to decrease in the dicalcium-silicate content in the melt as a result of its replacement by aluminum-bearing phases.
