Abstract: Disclosed are process and apparatus for use in the direct casting of metal strip (14) from molten metal deposited on a moving chill surface (12) from a tundish (10) having a floor (30), opposed upwardly extending sidewalls (32, 34), an end wall (36), an open outlet opposite the end wall with the open outlet extending substantially the full width of the tundish between the sidewalls, and an inlet (44) for providing a flow of molten metal (20) into the tundish from a source of molten metal (42). Flow diverters (56, 58) within the tundish divide the flow of molten metal into a plurality of separate streams and divert one of the streams in the direction of each sidewall and for recombining the diverted streams into a composite stream flowing toward the outlet. Flow diffusers (72, 74, 76) diffuse the molten metal flowing through the tundish to provide molten metal of substantially uniform temperature across the width of the tundish at the outlet.

Abstract: Procédé et appareil améliorés de coulée en direct de métal en fusion permettant de former une bande, par la solidification du métal en fusion sur une surface refroidie en mouvement (12), au moyen d'un récipient comprenant un creuset (30), des parois latérales espacées (32, 34), entre lesquelles se situent un orifice d'entrée (20) et un orifice de sortie (18) qui déverssent le métal en fusion sur ladite surface refroidie (12). On peut régler la dimension transversale de l'orifice de sortie pendant la coulée pour obtenir des bandes de largeurs différentes, au moyen d'un déflecteur central (44), avec de préférence des déflecteurs réglables (106, 108) qui ajustent le débit du métal en fusion de manère à fournir à l'orifice de sortie un flux de métal qui est sensiblement uniforme.

Abstract: A non-stick polymer coated aluminum foil and method of making it. The method of making a non-stick polymer coated aluminum foil comprising applying a curable polymer coating composition on at least a portion of one side of an aluminum foil and partially curing the coating composition to allow handling and further processing of the coated aluminum foil without blocking of the coating composition. The curing of the coating composition is completed by heating the coated aluminum foil in bulk. The polymer coating composition may include a cross-linkable polyester.

Abstract: Free-machining aluminum alloys are disclosed containing effective amounts of tin and indium. The tin and indium additions are especially adapted for use as free-machining constituents in aluminum alloys, such as AA2000 and AA6000 series aluminum alloys. The additions can be used in place of bismuth and lead in currently available free machining alloys. In alloys containing bismuth and tin, the indium can be used to replace the bismuth. A method of producing a free-machining aluminum alloy product also is described.
