Abstract:
A tundish having a normal maximum operating level of molten steel therein, said tundish comprising:a floor having an outlet, a pour zone, and side walls extending upwardly from said floor, said side walls extending above the normal maximum operating level of molten steel in said tundish; an impact pad positioned on said tundish floor in said pour zone, said impact pad comprising a base, an impact surface, an upwardly extending sidewall along the periphery of said base, said sidewall having an inner surface with an undercut portion facing incoming steel being poured in a stream into said pour zone, said undercut portion shaped to receive and reverse the direction of flow of the incoming steel stream; a dam positioned on said floor between said impact pad and said outlet, said dam having at least one hole therein allowing the passage of molten steel therethrough, so that molten steel may flow over said dam and through said at least one opening; and said dam extending upwardly from said floor a distance between about 40-60% of the normal maximum operating level of molten steel in said tundish.
