PCT No. PCT/GB96/00063 Sec. 371 Date Jul. 10, 1997 Sec. 102(e) Date Jul. 10, 1997 PCT Filed Jan. 15, 1996 PCT Pub. No. WO96/22853 PCT Pub. Date Aug. 1, 1997A tundish of improved flow characteristics for molten metal has an outlet in its base. The outlet is spaced longitudinally of the tundish from a pour zone. The pour zone is positioned to receive a stream of molten steel from a ladle. An impact pad is provided on the floor of the tundish in the pour zone, the impact pad comprising a base having an impact surface, an upwardly extending side wall along the periphery of the base, the side wall having an inner surface with an undercut portion to face the incoming steel stream, and the undercut portion having a surface shape to receive and reverse the direction of flow of the incoming stream. A dam is positioned between the impact pad and the outlet. The dam has one or more holes to allow through-passage of a proportion of the steel, and the dam extends upwardly from the tundish floor about 40-60% of the height of the uppermost level of steel in the tundish.
