The flow pattern in the tundish is critical for final product quality, as it influences the cleanliness of the steel entering the mold. Poor tundish practice can lead to surface level fluctuations, eroded refractory particles and cold regions, leading to defects in the cast product. On the other hand, by achieving an optimal flow pattern, it is possible to not only prevent inclusion formation but even promote their capture, leading to a cleaner steel. A desirable flow pattern also improves the control of steel composition and temperature. This paper presents fluid dynamic numerical simulations of different tundish furniture designs. The flow control devices position and size were optimized through a computational technique with the goal of maximizing the melt’s residence time in the vessel. By these simulations, it was possible to design effective tundish furniture to provide cleaner steel for the mold.
