Abstract The flux agents in common mould fluxes were fluoride and sodium oxide, which would do great harm to environments. B2O3 was selected as flux. The physical properties of B2O3��containing mould fluxes were studied. The corresponding physical properties of 37��91%CaO��43��09%SiO2��5%Al2O3��5%MgO��2%Li2O��7%B2O3 mould fluxes were as follows: the melting point was 909 ��, the flowing temperature was 1 160 ��, the viscosity and surface tension at 1 300 �� were 0��4 Pa��s and 0��32 N/m respectively, which could meet the demands for certain kinds of steels for mould fluxes in continuous casting.
