The invention relates to an impact pad (20), for use in a T-shaped tundish (10), the pad (20) comprising a base (21) having an impact surface and an outer side wall (22) extending upwardly therefrom and defining an interior space having an upper opening (24) for receiving a stream of molten metal, the interior space is divided into two regions (25a, 25b) by a separating wall (26) provided with at least one passageway (27) for the molten metal stream. This pad is characterized in that the separating wall (26) is at least three times higher than the outer side wall (22) and is inclined with respect to the vertical. This impact pads 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 (low level of slag emulsification). |
