摘　　要：利用开发的三维流场计算软件 ,研究了操作参数对武钢二炼钢板坯连铸机结晶器内钢液流动的影响。结果表明 :采用较大的水口浸入深度可以减小表面速度 ,抑制液面波动 ,避免钢渣卷混的产生 ;与圆形水口相比 ,长方形水口能有效地减小卷渣发生的可能性。The effect of different operation parameters on the molten steel flow in the mould in No.2 Steelmaking Plant, WISCO has been studied via the three-dimensional flow field software developed by the authors. The results show that the more deeper the nozzle immersion depth is, the less the molten steel velocity at the interface, the weaker the oscillation near the interface and the more difficult the occurrence of the slag entrapment become.Compared with the round entry nozzle, the rectangular entry nozzle can reduce the occurrence of the slag entrapment.
