The “Physiotherapist” of Aluminum Coils — Box-Type Aluminum Coil Annealing Furnace
This article provides an in-depth introduction to the box-type aluminum coil annealing furnace, a key piece of equipment in modern aluminum processing. It explains its core applications in eliminating work hardening after cold rolling, restoring ductility through controlled annealing, and enabling high-quality downstream forming. The article also covers furnace structure, including heating and circulation systems, atmosphere control, cooling technologies, and intelligent control systems, and outlines the complete annealing process from heating to soaking and cooling. As a flexible batch-processing solution, the box-type annealing furnace plays a critical role in helping aluminum processors meet diverse alloy, specification, and quality requirements.

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.
