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°C, the flowing temperature was 1 160 °C, the viscosity and surface tension at 1 300 °C 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.
