The effect of B<sub>2</sub>O<sub>3</sub> on the viscous characteristics of silicate-based fluorine-free mold flux was in-vestigated. In CaO-SiO<sub>2</sub>-Na<sub>2</sub>O slag system, the proper addition of B<sub>2</sub>O<sub>3</sub> can significantly reduce the viscosity and the breaking temperature. With the increase of the amount of B<sub>2</sub>O<sub>3</sub>, the viscosity of the mold flux gradually will decrease firstly and then remain relatively stable, and the breaking temperature will gradually decrease. The role of B<sub>2</sub>O<sub>3</sub> in CaO-SiO<sub>2</sub>-Li<sub>2</sub>O slag system was different. With the increase of B<sub>2</sub>O<sub>2</sub> addition, the breaking temperature of the mold flux gradually decreased, while the viscosity increased.
