Types of Rolling Mill. In metalworking, rolling is a way to shape metal by passing it through one or more pairs of rolls to make it thinner, make it the same thickness all over, or give it a certain mechanical property. The idea is the same as rolling out dough. The type of rolling is based on the temperature of the metal being rolled.Web
