Abstract：Based on the production in 1 300 mm×230 mm slab continuous casting mold and the similar principle, a 1:2 physical model was established to research the influence of nozzle bottom shape, nozzle immersion depth and casting speed on the fluctuation of meniscus by detecting the wave height. Then a optimized flow field was found through the trend of slag entrapment in slag entrapment experiment. The results show that the flow field of convex bottom nozzle is better than that of concave nozzle when the immersion depth is in the range of 180-260 mm. The fluctuation of meniscus increases with the rising casting speed, and it decreases with the increasing nozzle immersion depth. When the casting speed is in the range of 1.1-1.3 m/min and the immersion depth is in the range of 220-260 mm, the fluctuation of meniscus is changed between －4 mm and 4 mm, and no slag entrapment occurs.
