Abstract Billet quality is affected by the molten steel level behavior in mold. The molten steel level is a rotating parabolic surface with electromagnetic stirring. The liquid level fluctuation near the outlet of nozzle will be increased with the growing stirring intensity and casting speed， which can cause the slag entrapment to happen. Based on the parameters of [?]250 mm round billet continuous casting with mold electromagnetic stirrer in a steel plant， the combined method of turbulence model and multiphase-flow model(VOF) was adopted to establish the mathematical model and study the influence of nozzle submerged depth on the liquid level fluctuation in the mold with electromagnetic stirring. The results show that： increasing the submerged depth of nozzle can decrease the slag entrapment， which was caused by large current intensity and large casting speed.
