After the tooling and mill are designed, the mill is set up for production. Setup specifications can be found on a setup chart, such as the one shown in Figure 3. This chart lists the rolls, spacer length, side roll metal line, rim clearance, etc. for each pass, driven and idle, on the mill.
The production of aluminum/sheet/strip begins with the direct chill (DC) casting of large ingots, which are then homogenized. The homogenized ingots processes in a hot breakdown reversing mill to slab gauge and is subsequently hot-rolled, much like steel, in a continuous hot-tandem mill to transfer gauge.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
The mill stand will allow Shandong Rizhao to roll strips up to a length of 600 meters, which will be divided to mother plate lengths of maximum 50 meters by a "flying" cross-cut shear. The four-high reversing stand will have a rolling force of 90 MN.
