What is the process of rolling aluminum coil?

The process of rolling aluminum coil involves several key steps. Initially, aluminum ingots are heated to a specific temperature to make them pliable. Then, they are passed through a series of rolling mills where the ingots are pressed and shaped into thin sheets or coils. This process reduces the thickness and increases the length and width of the material. During rolling, the aluminum may be annealed to improve its ductility and strength. After rolling, the aluminum coil is cooled, cleaned, and inspected for quality. The final step includes coiling the rolled aluminum into manageable rolls for storage and transportation. This process is critical for producing aluminum coils used in various industries such as construction, automotive, and packaging.
