The influence of argon blowing at tundish bottom on flow field in tundish was studied by water modeling and industrial trial.Water modeling results showed argon bubbling could improve flow field obviously.The optimum argon blowing parameter is that the distance of permeable brick and ladle nozzle is 765 mm and argon blowing volume is between 0.06 m3/h and 0.10 m3/h.Industrial trial results showed the total oxygen content of slab was decreased 26.67% after acting argon bubbling curtain in tundish.With argon blowing, large-sized inclusions content of slab decreased from 0.430 mg/kg to 0.079 mg/kg.
