| 中文摘要 | In order to obtain the optimal structural parameters of the dug arch or round hole(s) at dam bottom in an 1820?tons asymmetrical T-type single-strand continuous casting tundish, the flow field profiles and temperature profiles of molten stainless steel in the tundish with arch or round hole(s) at dam bottom have been investigated using hydrodynamic modeling coupled with mathematical simulation. The optimal structural parameters of arch hole(s) at dam bottom can be obtained from hydrodynamic modeling as that two arch holes with 30?mm as height and 50?mm as radius are symmetrically dug at dam bottom with the distance between arch hole center and dam center as 205?mm; or the optimal structural parameters of round hole(s) can be recommended as that one round hole with 70?mm as diameter is dug at left of the dam bottom with the distance between hole center and dam center as 205?mm. The results of mathematical simulation suggest that digging arch or round hole(s) at dam bottom with above-mentioned structural parameters cannot obviously induce negative effects on streamlines and velocity vector profiles of molten stainless steel in the tundish by short circuit flow via arch or round hole(s) at dam bottom. The calculated temperature drop of molten stainless steel between the submerged ladle shroud and submerged entry nozzle in the tundish with arch or round hole(s) at dam bottom is about 3.0?K, the maximum temperature drop of molten stainless steel in the tundish is about 6.0?K. |
