With using established "liquid-slag" two phase flow model in mold for 180 mm x 180 mm billet by fluid mechanics software Fluent
the numerical simulation on behavior of liquid level fluctuation is carried out to study the effect of deviation distance of submerged nozzle from mold center (0 ~ 30 mm) and casting speed (2. 0 ~3. 0 m/min) on behavior of level fluctuation of liquid in mold. It is found that at same deviation distance of submerged nozzle
with increasing the casting speed
the trend of the whole for liquid level fluctuation increases
and the more of deviation distance and casting speed
the more of increment of liquid level fluctuation ; at low casting speed
the wave troughs occur at edge of nozzle with violent fluctuations around nozzle outlet; at high casting speed
the wave troughs occur at right wall of mold to intensify the liquid level fluctuation and easily form slag entrapment.
