The slab will be rolled again through the cold rolling mill until the thickness of the 8011 Jumbo Household Aluminum Foil Rolls is reduced to 4.5mm. Then, it is sent to the annealing furnace for annealing treatment. First, the slab is heated to 360°C and kept for 2 hours, and then heated to 580°C and kept for 18 hours, followed by homogenization annealing to ensure uniform grain size and consistent directionality. Subsequently, it is rolled again in a cold rolling mill to a thickness of 0.60mm and sent to an annealing furnace for intermediate annealing. At this time, the slab is heated to 460°C and kept warm for 5 hours, then cooled to 400°C and kept warm for 7 hours.

This series of annealing treatments can further improve the grain structure of the aluminum foil and improve its mechanical properties and processing performance.
A four-roller irreversible foil rolling mill is used to roll the 0.3mm aluminum foil wool that has undergone intermediate annealing treatment into finished products. This step requires strict control of rolling parameters to ensure that thickness, surface quality, etc. meet customer requirements.
The production process of aluminum foil is a complex and precise process, which requires strict control of various parameters to ensure product quality through reasonable process design and strict quality control.
Our core competitiveness lies in establishing long-term and stable cooperative relationships with customers and dealers, and winning a high degree of trust in the international market through high-quality products and services.
