Abstract

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 αβ) is better than the usual SEN,for this kind of SEN can stabilize surface turbulence and reduce penetration depth and get moderate velocity.
