Abstract: A tundish has an outlet and outlet shroud through which to deliver molten metal to a caster. The tundish is preheated at a heating station and moved to a casting station while supported on a moveable tundish car such that the tundish outlet is induced to a set position relative to the car and such that the tundish is located against horizontal movement at the position of a vertical central line of the tundish outlet but is free to move thermally about that position. Tundish is supported in a raised position on hoists during preheating and movement to the casting station and then lowered by actuation of the hoists to allow insertion of an outlet shroud into a metal distributor vessel of the caster.

Abstract: Twin roll casting method and apparatus in which molten metal is introduced between a pair of chilled rolls (16) via an elongate delivery nozzle (19) to form a casting pool (68) above the nip (69) between the rolls (16). Rolls (16) are rotated to cast a solidified strip (20) delivered downwardly from the nip (69). Delivery nozzle (19) comprises upwardly opening trough having side walls (62), a floor (63) and bottom outlet openings (64). A pair of upright flow barrier walls (84) stand up from floor (63) to define an internal trough channel (85) to receive the incoming flow of molten metal (65). Barrier walls (84) prevent direct flow of the incoming metal to the outlet openings (64).

Abstract: A refractory nozzle 19 for delivery of molten metal to a casting pool 68 of a twin roll caster, and a method and apparatus for casting strip 20 is disclosed in which said nozzle 19 has an elongate open topped trough 61 to receive molten metal, a pair of elongate nozzle chambers 82 extending one along each side of a floor 60 of a trough, metal flow openings 86 for flow of molten metal from the interior of the trough into the nozzle side chambers 82, and nozzle side outlets 64 for flow of molten metal from the side chambers 82 outwardly from the bottom of the delivery nozzle. In a preferred form the nozzle side outlets 64 are elongate slots extending continuously substantially throughout the length of the nozzle and the nozzle side chambers 82 are formed by partition walls 83, 84 disposed within the nozzle to divide off bottom side corner parts of the nozzle from the trough interior whereby the form said side chambers 82 extending along the bottom side corner parts of the nozzle.

Abstract: Metal strip (20) is cast from casting pool (68) of molten metal supported above nip (69) between chilled casting rolls (16). Molten metal is introduced into the casting pool by nozzle (19) having a trough (61) closed by a bottom floor (63). Metal is supplied to trough (61) in free-falling streams (65) which impinge on floor (63) and fan outwardly across the floor and through nozzle side openings (64) into the casting pool. Streams (65) are staggered longitudinally of the trough with respect to the side openings (64).

Abstract: A nozzle for delivering molten metal to a casting pool of a twin roll strip caster is formed in two halves and comprises an upwardly opening trough (61) to receive falling supply streams of molten metal and outlet openings (64) at the bottom of the trough. Nozzle end formations (87) define reservoirs (88) to receive separate supply streams of molten metal and flow passages (95) to direct metal from the reservoirs across pool confining end closures of the caster. Each reservoir (88) is separated from trough (61) by an upstanding wall (70) which functions as a weir for metal in the reservoir such that metal can flow over it into the trough when the reservoir is full.
