Taking the 90 ~ 105 t hot metal ladle at steel works as prototype
a geometric similarity ratio 1: 4 water model is established in laboratory and the effect of hot metal ladle side-blowing gas for auxiliary-deslagging on skimming area is studied by physical simulation method. Results show that as blowing gas rate is 0.25 〜2.0 m

/h
with increasing gas blowing rate the deslagging area increases ; and with increasing installed angle of porous brick from 0° to 70° and installed height from 174 mm to 294 mm
the deslagging area all increases. With using single porous brick side-blowing to deslag
installed angle 70°
installed height 294 mm and gas blowing rate 0. 8 ~ 1.2 m
