Abstract：Mixing time in bath， top blowing jet penetrating depth and emulsification rate between slag and molten steel were measured under different blowing conditions in 1/9 plexiglass model. Scrap movement status in dephosphorization pretreatment bath was studied. Suspension energy of different weight scrap in the bath was measured. To better understand the characteristics of dephosphorization pretreatment process， all the values were compared with normal steelmaking converter correspondingly. A and B two kinds of dephosphorization pretreatment conditions were compared according to the measurement results of water model. From the overall situation， the operation of A convert is more reasonable， phosphorus content after pretreatment in hot metal can be reduced to 0.010%-0.015%， be equivalent to the level of Japan’s Wakayama Steel Plant.
