To avoid slag sticking onto the snorkel during CAS-OB ladle refining process, B2O3-CaO(mass ratio equals 1:1) and CaF2-CaO(mass ratio equals 1:1) were respectively employed as modifiers added to decrease the viscosity of ladle slag. The rotary cylinder method was adopted in the viscosity measurements. The results showed that the modifiers could decrease the viscosity of ladle refining slag remarkably. At 1500°C, the viscosity of ladle slag without any modifiers is about 6.0 Pa·s. But by adding more than 10mass% CaO-B2O3 or CaO-CaF2, the slag viscosity at 1500°C could be decreased lower than 1.0 Pa·s. The mechanism of modifiers decreasing the slag viscosity was analyzed.
