[57] Abstract: A tundish imp act pad formed from refractory material comprises a base having an impact surface which, in use, faces upwardly against a stream of molten metal entering a tundish, and a wall extending upwardly from the base around at least a part of the periphery of the impact surface. The wall has at least one latitudinal portion. An inwardly-extending feature protrudes from the latitudinal wall. The inwardly-extending feature inhibits flow exiting the impact pad from passing over the center of the latitudinal portion of the wall.
