Test on Physical Simulation of Three-fluid Tundish Flow Field

The three-fluid tundish was chosen as research object to make water simulation tests in The Special Steel Plant of Laiwu Steel.By analyzing RTD curves and flow fields and combining with the production and the convenience of use,twenty-nine testing programs were designed by changing the setting of retaining wall and turbulence inhibitor.The results indicated that the inner structure of prototype tundish was unreasonable,which the functions would not be utilized.There were many problems in tundish flow field,such as short flow serious,oversize dead zone,stagnation time difference from each fluid and inclusions removing.The tundish flow field was properly with 1 type retaining wall + 10°+ cushion + 4 type turbulence inhibitor.
