The melting point and viscosity of refining fluxes for desulphuration have been studied of which CaO (balance)-SiO

(10%) refining slag was as basic flux
when the ratio of (CaO+RxO)/SiO

was fixed at 2.5(where RxO- BaO or Li

the BaO or Li

O added and replaced equivalent CaO content in flux. The results showed that the melting point and viscosity of fuxes decreased by added BaO or Li₂O in CaO basic slag effectively to improve the dynamics condition of metal- slag reaction. With 15% BaO or 15%Li₂O
the melting point of flux was 1267 ℃ or 1185 ℃ which were far lower than that of flux free additions- 1326 ℃
and the viscosity o
f flux at 1475 ℃ was 0.98 Pa · s or 0.51 Pa · s which were also far lower than that of flux free additions- 1.79 Pa · s to make the fluxes had excellent flu- idity and melting capacity.
