Metal Rolling Manufacturing
One of the goals of roll pass design is to properly design a series of reductions in such a way as to mitigate the relative differences in shape change between areas, in order to avoid material defects. Improper reductions of the product can cause warping or cracking of the material. Metal rolling practice is not always the cause of warping or cracking, sometimes defects in the metal being

Rolling (metalworking) Wikipedia
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
