摘　　要：通过水模型试验和工业试验，研究了中间包底吹氩参数对中间包流场的影响。水模型试验结果表明：中间包底吹气可以改善中间包流场，较佳的吹气参数是透气砖距离冲击区765mm，吹气量在0．06～0．10m^3／h。工业试验结果表明：中间包采用底吹氩后，T[O]降低了26．67％；大型夹杂物总含量由0．430mg/kg降至0．079mg/kg，降低了81．82％。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 m^3/h and 0.10 m^3/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.
