Abstract：In order to reduce the probability of slag entrapment in thin slab continuous casting funnel mold at high casting speed, a new submerged entry nozzle (SEN) suitable for the use of funnel mold in thin slab continuous casting was designed. The numerical simulation study was carried out by Fluent software, and the influence of the new SEN on the surface velocity and slag entrapment of the funnel mold with cross-section of 1 520 mm×73 mm was analyzed under different casting speeds (4, 5, 6 m/min) and submerged depths (130, 160, 190 mm). The numerical simulation results show that the maximum surface velocity value of the funnel mold is 0.37 m/s, the maximum fluctuation of the liquid level is about ±5.4 mm, there is no obvious slag entrapment phenomenon at the liquid level, and the simulation results are good. The new SEN designed provides some reference experience for the future design of thin slab continuous casting SEN.
