Nov 03, 2021 The process starts when the rolling mill gets aluminum slabs or billets ready for rolling. Depending on the desired materials properties for a particular roll, they must first decide whether to heat the stock or not. If they do not heat the aluminum before rolling, the aluminum will be cold worked.

The cold rolling aluminum sheet producing process is started from cast volume(8 mm thickness) which is made by cast machine, then rolling the cast volume by cold rolling machine. While the hot rolling aluminum sheet is made by heating aluminum ingots (400-500 mm thickness), and then rolling it by hot rolling machine at high temperature.
Common items produced by this process in manufacturing industry today include rings for machinery, aerospace applications, turbines, pipes, pressure vessels, roller and ball bearing races. The following shows the sequence of events of the ring rolling process, the part is commonly started as a metal bar cut to a certain length.
The ring rolling process starts with a circular preform of metal that has been previously upset and pierced (using the open die forging process) to form a hollow “doughnut.” This doughnut is heated above the recrystallization temperature and placed over the idler or mandrel roll.

Regardless of the process used, there are common rolling defects that arise from time to time. Rolling is the process in which a metal stock passes through rollers to reduce and unify thickness. Cold rolling occurs when performed at temperatures below the re-crystallization point.
The temperature is further enhanced by the speed of the process. Lubrication is used in the roll forming process to reduce friction between the rolls and metal to prevent tool wear. Friction is a necessary part of the rolling process and an important part of shifting the metal forward between the rollers.
Obviously, this is going to really be dependent on the grade of aluminum. That said, the basic process is generally the same. Heat it up to a certain temperature, hold it at that temperature, then cool it down. After you’re done working on it, it’s pretty easy to restore
During this rolling process, the aluminum occasionally must be annealed (heat-treated) to maintain its workability. The reduction of the foil is controlled by adjusting the rpm of the rolls and the viscosity (the resistance to flow), quantity, and temperature of the rolling lubricants.
