Rolling

Alcoa Australia Rolled Products operates two rolling mills – Point Henry near Geelong in Victoria and Yennora on the outskirts of Sydney in New South Wales.
 
Once aluminium has been smelted from its oxide form – alumina, the aluminium ingots created are transferred to a hot rolling mill.
 
The ingots are heated to around 600 degrees Celsius and passed back and forth up to 28 times through a hot reversing mill.  This turns the ingot into a long aluminium strip approximately 100m long and 18mm thick.
 
The strip is then transferred to the hot continuous rolling mill where it is passed through two more rolling stands to further reduce the thickness to between 2mm and 6mm before being coiled and cooled.
 
Once cooled, the coil is transported to the cold rolling mills where the aluminium’s thickness is again reduced – depending on its end use the aluminium can be reduced to a thickness of just 0.25mm.
