Rolling mills Various rolling mill configurations are available (see next figure): 1. Two-high rolling mill: consists of two opposing rolls. These rolls may rotate only in one direction (nonreversing) or in two directions (reversing). 2. Three-high rolling mill: allows a series of reductions without the need to change the rotational direction ...
