摘要： An impact pad (20), formed from a refractory material capable of withstanding contact with molten metal, comprises a base (12) serving in use as an impact surface for molten metal, and a sidewall (14) extending generally upwardly therefrom. The sidewall (14) terminates at an upper surface (16) which is above the base (12) in use such that the base (12) and sidewall (14) define a receptacle for receiving molten metal. The sidewall (14) contains therein at least one channel (22), the at least one channel (22) having first and second ends (24, 26); the first end (24) being relatively closer to the base (12) at its intersection with the sidewall (14) than the second end (26). The at least one channel (22) being open ended at the second end (26) or tapering such that the at least one channel (22) has zero depth at its second end (26). The invention also relates to a tundish including an (15) impact pad (20) as described above.
