  • Patent number: 5338009
    Abstract: A tundish has an entry location for receiving a molten alloy, such as steel, and bottom outlet openings for withdrawing the molten alloy. The tundish bottom comprises a sump located downstream of the inlet location and upstream of the outlet openings. Undissolved, molten alloying ingredient, denser than the molten alloy as whole, (e.g. lead or bismuth in the case of molten steel) accumulates in the sump. The sump has a floor and passageways which extend downwardly from the sump floor to a drain in the steel tundish shell underlying the sump. The passageways are permeable to undissolved, molten alloying ingredient but impermeable to the molten alloy. There are expedients for maintaining the passageways at a temperature which prevents undissolved alloying ingredient descending through the passageways from cooling to a temperature at which the undissolved alloying ingredient blocks the passageways against further passage by undissolved, molten alloying ingredient.

  • Patent number: 4591135
    Abstract: An elongated tundish for the continuous strand casting of molten metal has a plurality of outlet openings arranged in a row extending in the longitudinal direction of the tundish. There is an elongated dam extending in said longitudinal direction between the row of outlet openings and the location of impact, on the tundish bottom, of a ladle nozzle stream of molten metal. The dam provides uniform residence times in the tundish for molten metal exiting the tundish at inner and outer outlet openings in the row of openings. Fluid flow control structure is located between the dam and the tundish side wall adjacent the row of outlet openings to avoid a dead zone in that region.
