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.
14. For use in a tundish having a normal maximum operating
level of molten steel therein, 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, a tundish furniture kit, said kit
comprising:
an impact pad for positioning 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
for facing incoming steel being poured in a stream into said pour
zone, said undercut portion shaped for receiving and reversing
the direction of flow of an incoming steel stream;
a dam for positioning 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 when
said dam is installed molten steel may flow over said dam and
through said at least one opening; and
said dam having a height such that when installed it extends
upwardly from said floor a distance between about 40-60% of the
normal maximum operating level of molten steel in said tundish.
