Abstract:

A tundish impact pad formed from refractory material comprising a base having an impact surface which, in use, faces upwardly against a stream of molten metal entering a tundish, a wall extending upwardly from the base around at least a part of the periphery of the impact surface, one or more portions of the upper part of the wall supporting one or more overhangs which project inwardly over the periphery of the base. At least one of said overhangs has at least a part whose under-surface curves or slopes, the curvature or slope lying in a direction along the length of the wall. Preferably the pad has rectangular base and a pair of opposite walls is provided with an overhang that arches upwardly towards the centre of the wall. An overhang on the second pair of walls can be, for example, planar and parallel to the base. The width of the curved or sloping overhangs increases in both directions away from its centre/top.
