Coupled Numerical Simulation on the Process of Molten Steel Flow and Heat Transfer of Six-strand Tundish

The method of coupled numerical was taken on the heavily temperature dropping of six-strand special unsymmetrical tundish.The flow field and temperature field in the tundish were calculated and optimized.The result show that when the special tundish was used without any flow control devices,it had a very short flow route between entry and near outlet,the biggest temperature difference between near outlet and far outlet is 8 ℃;The optimized tundish avoid the short flow route and uniform the molten steel temperature of each nozzle,and the biggest temperature difference reduced to 3.3 ℃.It is better than the original one and meet the requirement of actual operations.
