    摘要: 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).

    摘要: Process and apparatus for continuous casting of metal strip in which a layer of liquid parting agent, and any solid detritus contained therein, is completely removed from a casting surface of a rotating belt after contact with the metal, and in which a new layer of liquid parting agent is applied to the casting surface thereafter and prior to renewed contact with the molten metal. The removal of used parting agent and the application of fresh helps to prevent the formation of surface blemishes and defects on the cast metal strip product. Such blemishes and defects can also be minimized by using an injector having a flexible tip used to inject the molten metal onto the casting surface and preferably one or more spacers to create a gap between the tip and the casting surface itself. The spacer is preferably a screen of wire strands orientated to minimize disruption of the new layer of liquid parting agent applied to the casting surface. By avoiding disruption of the new layer of liquid parting agent, surface blemishes on the cast product are minimized. The invention also relates to the molten metal injector having a flexible tip and optionally provided with spacer elements.

    摘要: Disclosed is an improved casting tip (14) for a nozzle of a continuous caster, the tip designed for transferring molten metal (4) from a molten metal reservoir (2) to a continuously advancing mold as formed, for example, by twin belts (18), rolls (24) or block casters (28) for casting molten metal into solid form (22). The casting tip (14) is comprised of a top wall (44), a bottom wall (46) oppositely disposed from the top wall, a first side wall, and a second side wall oppositely disposed from the first side wall, the first and second side walls joined to the top and bottom walls to form a passage therebetween having an entrance and an exit. The passage has a top wall inside surface (52) having a first portion (56) that first converges towards the bottom wall starting at the entrance and has a second portion (60) that diverges from the bottom wall to the exit, the top wall first portion having a length less than the top wall second portion length. Further, the passage has a bottom wall inside surface (54) having a first portion (58) that first converges towards the top wall starting at the entrance and has a second portion (62) that diverges from the top wall to the exit, the bottom wall first portion having a length less than the bottom wall second portion length. The top wall and bottom wall converge and diverge about substantially an equal amount from a center line from the entrance to the exit of the passage.

    摘要: Metal strip may be cast directly from molten metal (18) in an open tundish (16) onto a chill roll (10). Strip thickness is controlled by contouring the tundish lip (32) with an offset near the casting wheel. This can be used remedially to offset the natural tendency for the strip to be thicker near the edges, which is undesirable for cold rolling, or it may be used creatively to produce contoured strip.

    摘要: Un procédé et un dispositif permettent de couler de minces bandes métalliques. Le métal fondu (1) est coulé sur au moins un corps de refroidissement parmi deux corps de refroidissement en mouvement qui forment une fente intermédiaire de passage. Une bande (5) à profil de solidification concave se forme sur ce corps de refroidissement (3). Sur l'autre corps de refroidissement (8) le métal fondu (6) forme une pellicule qui dans la fente de passage est réunie avec la bande (5) partiellement solidifiée, au moins par les flancs latéraux externes solidifiés de cette dernière, et la bande (9) est calibrée pour prendre ses dimensions définitives. On continue à refroidir, de préférence sur le deuxième corps de refroidissement (8), la bande qui est ainsi fermée de tous les côtés et dont le noyau est encore fondu ou pâteux jusqu'à sa solidification totale.

    摘要: A tundish (32) for containing molten metal and delivering the metal to a work zone where the metal solidifies as it is moved through the work zone in a continuous casting process, the tundish comprising means for containing the molten metal and including an outlet, a pervious flow restricting element being positioned in the outlet to permit flow of molten metal into the work zone, the element causing a pressure drop in the flow of the metal across the element and the flow through the element being distributed throughout the pervious element, the element also providing a temperature gradient between the molten metal in the tundish and the work zone to permit the tundish to contain molten metal at elevated temperatures while the molten metal entering the work zone is near the solidus/liquidus temperature of the metal. The invention also provides a method and apparatus for using the tundish in association with a chilled substrate (36) moving through the work zone.
