摘要：

The dead volume fraction of the fluid in the multi-strand tundish can not be analyzed accurately when adopted the common method. Accordingly the whole flow pattern can not be expressed accurately. In order to solve the problem, the concept of the combined RTD curve for the multi-strand tundish is presented, and it is applied to the modified combined model, and the analysis method of the combined RTD curve for the fluid in multi-strand tundish is formed. The piston flow, mixed flow and dead zone volume fraction can be calculated by the method. A new explanation for the mean residence time of multi-strand tundish is also clarified. The method has been used to analyze the flow pattern of a six-strand tundish.
