Abstract

The phosphorus, manganese, and chromium distribution ratios between BaO-MnO fluxes and liquid Fe-Cr-Mn-Csatd. alloys have been measured at 1573 K by using a chemical equilibration technique. The distribution ratio of phosphorus between BaO-MnO fluxes and liquid Fe-Cr-Mn-Csatd. alloys decreases and those of chromium and manganese are nearly constant with increasing chromium content of the metal. With increasing the BaO content of flux the phosphorus distribution ratio is found to increase. The chromium distribution slightly increases and that of manganese decreases at the same time. The possibility of dephosphorization of Fe-Cr-Mn-Csatd. melts by using BaO-MnO fluxes is discussed.
