| Abstract Scope |
This paper presents a new continuous casting process for aluminum alloys, jointly developed by Golden Aluminum (GAI) and SMS Group. The new “NexCast” process is designed to produce aluminum sheet with high end of life scrap content, including high alloyed aluminum grades like AA5182 and heat treatable 7xxx series alloys, typically inaccessible to traditional continuous casting processes. Nexcast overcomes the limitations through a specially designed, continuously moving mold that produces a rapidly cooled 20 mm thick plates. Alloy elements and impurities are kept in solid solution, directly influencing microstructure evolution during downstream hot and cold rolling and annealing and tailored textures and grain refinement are achieved through the control of key process parameters. Compared to direct chill (DC) casting and twin roll casting (TRC) “NexCast” offers distinct metallurgical advantages, a shorter processing sequence, and significantly lower energy . The result is a cost-effective, high-performance sheet product suitable for many applications. |
