Abstract
An impact pad, for use in a T-shaped tundish, comprises a base having an impact surface and an outer side wall extending upwardly therefrom and defining an interior space having an upper opening for receiving a stream of molten metal, the interior space being divided into two regions by a separating wall provided with at least one passageway for the molten metal stream. The separating wall is at least three times higher than the outer side wall and is inclined with respect to the vertical. This impact pad increases the homogeneity of the molten steel cast from the different outlets of the T-shaped tundish and provides equal or relatively similar residence times of the molten steel discharged through the different outlets of the tundish. This impact pad also permits a fast transition of the steel quality at ladle change while retaining the advantages of conventional impact pads.
