Combined with relative parameters of a 100 t vacuum refining furnace with single snorkel at steel works

the imitated calculation for liquid field in degassing of vacuum refining furnace with single snorkel has been carried out by numerical simulation method to analyze the basic characteristics of liquid flow in furnace with single snorkel

and the effect of blowing position with distance from bottom center 0. 1 ~ 0. 424 m on liquid flow field

liquid circulation rate and mixing time is studied. Results show that for origin argon blowing position (distance from bottom center 0. 424 m) the most argon doesn't enter into snorkel

in order to avoid argon escape

the blowing nozzle distance from bottom center should be ≤ 0. 3 m

with increasing blowing nozzle distance

mixing time of liquid decreases

and combined considering the effect of liquid degassing and life of snorkel

the optimum gas blowing position is at distance from bottom center 0. 25 ~ 0. 3 m.
