An aluminum sheet rolling mill is a manufacturing facility that produces aluminum sheets by passing heated aluminum ingots through a series of rollers to reduce the thickness of the metal and produce a uniform, flat sheet. This process is called rolling and it is the most common method used to produce aluminum sheets for a wide range of industrial and commercial applications.

The aluminum sheet rolling process typically involves the following steps. 

Melting and Casting

Aluminum ingots are melted in a furnace and then cast into large, rectangular blocks called slabs.

Heating

The slabs are heated to a temperature of around 500-600°C (932-1,112°F) to make them more malleable.

Hot Rolling

The heated slabs are then passed through a series of hot rolling mills, which use a combination of pressure and heat to reduce the thickness of the metal and produce a long sheet.

Cold Rolling

The hot rolled sheet is then passed through a series of cold rolling mills, which further reduce the thickness of the metal and produce a uniform, flat sheet.

Annealing

The cold rolled sheet may then be annealed, or heat-treated, to improve its strength and ductility.

Finishing

The aluminum sheet may undergo further processing, such as cutting, trimming, or surface finishing, before it is shipped to customers.
