The effect of argon blowing rate (150 ~450 IVmin) and argon blowing location at ladle bottom (ladle center to 3/4 radius of submerged snorkel) on average flow rate at metal-slag interface in 130 t single snorkel furnace with desulphurizing top slag is simulated by Fluent software and VOF model. Results show that the suitable blowing location is at 1/2 radius (R) of submerged snorkel
the average flow rate at metal-slag interface increases with increasing blowing rate
with definite blowing rate and blowing at 1/2R the average flow rate at interface is maximum
and only as blowing location is﹥ 1/2R
the effect of blowing location has obvious effect on variation of slag phase volume fraction at interface.
