If you search the Internet for what a cold-rolling mill is, one might be hard-pressed to find a description to relate to and understand. It is important to preface that what is involved in the process of re-rolling aluminum coil or strip is quite capital intensive, which explains why there are limited mills in the United States that will flat roll aluminum coil.
Tandem cold mill - The most efficient solution AA3xxx and AA5xxx-series aluminum grades are typically used for manufacturing beverage cans. This is where tandem cold mills (TCM) offer you the most efficient solution. Operating several single-stand mills doesn't make economic sense, especially if you want a production volume of up to 400,000 tpy.

3.The production process is different: cold rolling is processed by a casting machine into a cast roll (8mm thickness) and then processed by a cold rolling mill. While as for the hot rolling is performed by heating an aluminum ingot (400-500 mm thickness) and rolling it at a high temperature by a hot rolling mill. 4.Different performance.

The function of the aluminum rolling mill is to roll the original aluminum into a Cast-rolled alloy strip suitable for cold rolling. The molten aluminum must be supplied continuously. The melt of aluminum alloy must be clean and have the same chemical composition, and the liquid level and temperature must be constant.
The difference between cold rolled aluminum coil and hot rolled aluminum coil is mainly due to the difference in the production process. Cold rolled is processed by casting machine into casting roll and cold rolling mill. Hot rolling is caused by heating of aluminum ingot. Under the smelting and casting into flat ingots, through the milling surface, homogenized by the hot rolling mill …
Figure 1 presents the manufacturing processes of rolled aluminum products. Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls.
