 abstract={Lubrication and heat transfer control are two significant functions of mold fluxes. In order to coordinate the contradiction between lubrication and heat transfer, the effects of BaO and Li2O on basic characteristics of CaO-SiO2 based mold fluxes were studied by hemispherical melting temperature instrument, rotating cylinder method, X-ray diffractometer (XRD) in present study. The results show that the melting temperature and viscosity at 1300°C all represent a downward trend with BaO and Li2O enhancement at different basicity, and the break temperature decrease with BaO addition while decrease and then increase with Li2O addition, which illustrates that Li2O content should be no more than 0.8 wt% for the purpose of lubrication. Meanwhile, to ensure a sufficient thickness of the liquid slag film and avoid discontinuity of the liquid slag film, the BaO content is better to be 10 wt% with low melting temperature and viscosity. The main crystalline phase in the mold fluxes is cuspidine (3CaO·2SiO2·CaF2), and the crystallization ratio rises sharply when basicity increased to 1.65. For better deal with the contradiction of lubrication and heat transfer, the mold fluxes composition w(BaO) = 10 wt%, w(Li2O) = 0.8 wt%, R ≥1.65 is reasonable, which has a profound impact on high crystallization and lubricity mold fluxes.},
