The flow field in original tundish with single-line type retaining wall
rectangular guide-flow-hole and level- no dip angle and in improved tundish with V- type retaining wall
Φ80 ~Φ 120 mm round guide-flow-hole and dip angle 0°- 40
°
and adding turbulence inhibitor has been tested and studied by using geometric similarity 1:2.5 water model. It is obtained that the structure of improved tundish with V- type retaining wall +30° angle and diameter Φ80 mm guide-flow- hole + deep disc-lip type edge turbulence inhibitor is optimal
it may prolong the residence time of liquid in tundish and the percentage of dead zone volume of liquid decreases to 10.3% 〜10.9% from 48.16% ~63.06% in original tundish
and is in favor of inclusions in liquid to quick floating off.
