Fluid Flow Control Structure For Tundish

View page
US Patent:
45911355, May 27, 1986
Filed:
Sep 27, 1984
Appl. No.:
6/654738
Inventors:
Donald R. Fosnacht - Crown Point IN
Masood A. Tindyala - Highland IN
Assignee:
Inland Steel Company - Chicago IL
International Classification:
C21C 106
US Classification:
266275
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.

Tundish For Molten Alloy Containing Dense, Undissolved Alloying Ingredient

US Patent:
53380096, Aug 16, 1994
Filed:
Nov 10, 1993
Appl. No.:
8/150556
Inventors:
Howard M. Pielet - Munster IN
William J. Kreevich - St. John IN
Masood A. Tindyala - Griffith IN
John R. Knoepke - Munster IN
Assignee:
Inland Steel Company - Chicago IL
International Classification:
B22D 3700
US Classification:
266229
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.
