摘要：
The paper present the results of computational calculation showing liquid steel flow in the tundish. The one-strand slab tundish is used to casting slabs. The internal work space of tundish was modified by two flow control devices (FCDs). The first device is subflux turbulence controller situated in the pouring tundish zone. The second FCD is a dam with two holes. The dam presently using in the industrial conditions was modified by changing a height. Adapted to internal work space new flow control devices were located in the tundish virtual model. Numerical model and computational grid of tundish was performed in the Gambit application. The visualization of interaction of flow control devices on hydrodynamic conditions was received from numerical simulation. As a results of the computations carried out, liquid steel flow fields, turbulence intensity maps, steel temperature maps and RTD curves (E and F) were obtained. On the distribution of RTD characteristics, percentage contributions of stagnant, plug, ideal mixing flow type, and transition grade zone were calculated.
