ABSTRACT (735/MAS/97) A TUNDISH IMPACT PAD AND A TUNDISH COMPRISING THE SAME The tundish impact pad comprises a body of refractory material capable of withstanding contact with molten steel, the body comprising a base having an impact surface for molten steel, an outer sidewall extending upwardly from the impact surface, the outer sidewall extending around the base to completely enclose it, an annular body portion connected to the sidewall and providing a top surface substantially parallel to the impact surface and defining an opening into which molten steel can be poured, the lower surface of the annular body portion and the inner face of the sidewall defining a recess having an undercut portion extending continuously around and above the impact surface, wherein a first portion of the top surface is at a lower level than the remainder of the top surface and the recess beneath the first portion of the top surface is of smaller cross-section than the remainder of the recess. The impact pad is particularly intended for use with a longitudinally-extending tundish having a steel inlet zone towards the end opposite to the outlet zone(s). The invention also provides a tundish comprising the said tundish impact pad.
