John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 4.2.1.1 Plane-Strain Flow. The flat rolling process is usually taken to be essentially two-dimensional in the sense that the width of the product does not change much during the pass when compared to thickness and length changes and this makes the assumption of plane-strain plastic flow 5 quite realistic.

In this case, the slab is rolled in a continuous mill and then wound into an aluminum coil. The distinction between them is that plate is the term used for flat metal that is more than 3 millimeters thick, while sheet refers to metal that is less than 3 millimeters thick. Foil has a thickness that is less than .15 millimeters.

Also, minimum and maximum width is important. Even something as straightforward as material thickness can vary, yet still fall into accepted plate and sheet mill tolerances. For instance, a 0.25-in. plate can sometimes vary in thickness from 0.23 to 0.262 in.

If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.
