The types of rolling mills based on roll configurations are described below and are shown in Fig 3. Two-high mills – These mills have the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally ...
Three-high Rolling Mills: In a three-high rolling mill configuration, three rolls are placed face to face. With the reverse rotations of these rolls, the work part can be passed through these two rolling mechanisms consecutively. After each pass, the work part must be oriented to another pass. Some moving and elevator mechanisms can be required.

Tandem Rolling Mill Rolling mills have several stages, where the each stage successively reduces the thickness of the stock until the desired cross section is achieved.
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, England.In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved …
