摘要： A start-up method and apparatus for continuous casting of molten metal into a cast strip product includes initially casting a start-up alloy having sufficient strength, flexibility and casting surface release properties to achieve steady state casting conditions. A target alloy follows the start-up alloy being cast to produce a cast strip product of the target alloy composition. A start-up alloying vessel is disposed between the source of the target alloy and the casting apparatus to facilitate introduction of a start-up alloy into the casting process or formulation of a particular start-up alloy for initiation of the continuous casting operation.

摘要： A method and apparatus for trimming edge scrap from continuously cast metal strip includes an edge trimming device in combination with a drag casting apparatus for producing aluminum or aluminum alloy cast strip. The edge trimming device includes a tool which marks the casting surface of the casting wheel to disruption the solidification rate during casting of the molten aluminum. Disruption of the solidification rate forms a longitudinal split in the strip being cast resulting in formation of a high quality cast strip product acceptable for further processing and edge trim scrap. The edge trim scrap may be recovered and recycled for further use. The edge trimming device includes adjustable features to permit varying the location of the longitudinal split along the width of the strip being cast in response to casting parameters such as excess gauge variation, surface defects or changing of the cast strip width prior to or during the continuous casting operation.

摘要： A method for making aluminum foil comprises providing an aluminum-based alloy composition consisting essentially of about 0.05 to 0.20 weight percent silicon, about 0.02 to 0.50 weight percent iron, about 0.05 to 0.30 weight percent copper and balance aluminum and inevitable impurities and grain refining elements, wherein the ratio of iron to silicon ranges between about 2:1 and 4:1. The aluminum-alloy composition is continuously cast using a unitary and chilled casting wheel to form a cast strip product of desired width and gauge. The cast strip product is then homogenized, cold rolled and recrystallized annealed into an aluminum foil product. The aluminum-based alloy composition produces a single roll cast product having minimum microshrinkage porosity on the air surface thereof. Reducing or eliminating the microshrinkage porosity in the cast product results in an aluminum foil product having a minimum of pinholes in the final foil product.
