Application of Copper Roll Shell in Twin-Roll Casting and Rolling Process
Copper roll shells made of Be–Cu alloys offer thermal conductivity 3–4 times higher than steel roll shells, enabling faster solidification and casting-rolling speeds up to 10–12 m/min. This significantly improves aluminum strip quality and production efficiency. Key benefits include lower thermal stress (−30–50%), finer microstructure, and energy savings of about 20%. Main challenges—such as roll sticking and water sealing—can be addressed through surface pretreatment, optimized process control, and improved sealing design. Industrial results show doubled productivity and reduced cold rolling passes, confirming copper roll shells as an effective solution for high-speed, thin-gauge, and high-quality aluminum strip production.

Essential Components and Working Principles of the Coil Transport System in Aluminum Foil Production
The coil transport system in aluminum foil production is vital for efficient and high-quality output. It manages the transportation, storage, and precise control of aluminum foil coils, ensuring stability and preventing issues like wobbling. Key components include the unwinding machine, which starts the process, and the rewinding machine, which finishes it. Additional equipment includes conveyors, lubrication systems, and cooling systems. The system's working principle involves synchronizing the unwinding and rewinding processes with the rolling speed to maintain stability. Key challenges include managing negative roll gap rolling and addressing issues like sheet shape, requiring precise control and advanced technology.
