Compared to the straight nozzle, the SFN generated a strong swirling flow along with the upper and lower recirculation region in the mould, and created an active bulk flow below the meniscus, which can move the hot spot upward to improve the melting of mould powder and promote superheat dissipation of the molten steel. Most importantly, with the adoption of the SFN, the simulation results show that the temperature dis-tribution in the mould together with the thickness of solidified shell at the cross-section will be more even with the increase of the mould corner radius, and the level fluctuation conditions at the free surface can also be improved.KEYWORDS: mould, continuous casting, swirling flow, solidification, corner radius
