Abstract
The flow field of molten steel in the three-strand tundish was studied by the commercial software CFX and the water simulation.After analyzing and comparing the flow state of the original and improved tundish,the results are obtained as follows:The results of numerical simulation are the same as that of hydraulic model.The apparent short road flow is found in the original tundish and the proportion of dead zone is large,which is more than 50%.After transforming the tundish,the flow performance of the molten steel in the tundish has been improved significantly and the dead volume fraction is reduced sharply to less than 20%,the minimum value is only 9.41%.The field experiment shows that the maximum temperature differences of molten steel between middle and side nozzle outlet has been reduced from 5℃ to 2℃.The accident rate has been decreased obviously so as to reach the expected metallurgical results.
