Abstract:
An elongated tundish for continuous casting molten metal, comprising:an elongated tundish including a pair of spaced side walls disposed in a longitudinal direction and a pair of spaced end walls extending in a lateral direction between the side walls and a floor,the floor including a molten metal impact area, a molten metal outlet, a weir between the impact area and outlet, and first and second ramps, each having first and second surfaces,the first ramp positioned between the weir and the outlet while extending in the lateral direction, the first surface adjacent the outlet and inclined downwardly, the second surface facing the weir and being substantially vertical,the second ramp positioned between the weir and the impact area while extending in the lateral direction, the first surface adjacent the weir and inclined downwardly, the second surface facing the impact area and being substantially vertical,whereby the substantially vertical second surfaces cause molten metal to flow in a direction generally upwardly from the impact area and toward the outlet thereby minimizing entrainment of gas bubbles and slag within molten metal.
