Aluminum Hot Rolling Mill


Our large aluminum hot tandem rolling line is designed for large-scale, high-efficiency, and high-precision hot rolling of aluminum and aluminum alloy sheets and strips. Adopting proven “1+4” or multi-stand tandem rolling technology, the line integrates roughing mills, finishing mills, roller tables, on-line cooling, and advanced automation systems, directly converting thick ingots into high-quality hotrolled coils. With large capacity, high automation, and excellent thickness and flatness control, it is the core equipment for producing high-end aluminum materials such as battery foil stock, automotive body sheets, can stock, and architectural panels, widely used in large aluminum processing plants.
