摘　　要：采用1∶1水力学模拟方法研究了板坯连铸结晶器内流场,探讨了双侧4孔水口出口方向对结晶器内液面波动、表面流速和注流冲击深度的影响趋势,得到了双侧4孔水口出口方向对板坯连铸结晶器内流场的影响规律。研究结果表明:4个孔都向下(α<β,α与β都向下)的双侧4孔水口的方案较优,此水口的冲击深度低,液面波动小,表面流速适中,比普通双侧孔水口效果好。The fluid flow in the mould of slab continuous caster was investigated by 1∶1 ratio water modeling simulation system.The effects of outlet angle of Bilateral and quadripuntal SEN on surface turbulence,penetration depth and surface velocity were discussed and the regularity of the flow field for change of outlet angle in slab continuous casting mould was obtained.The results show that the case C（both α and β are downward angle and α〈β） is better than the usual SEN,for this kind of SEN can stabilize surface turbulence and reduce penetration depth and get moderate velocity.
