<p>A tundish impact pad formed from refractory material is disclosed, the impact pad comprising a base having an impact surface which in use faces upwardly to receive molten metal, e.g. steel, poured onto the impact pad, and a sidewall extending upwardly from at least part of the periphery of the impact surface. At least part of the interior, and a surface, of the sidewall are porous and the impact pad includes means for supplying a gas, e.g. argon, to the porous interior of the sidewall, to enable the gas to be supplied to the molten metal from the porous surface of the sidewall. The tundish impact pad may be used during the continuous casting of steel.</p> |
