This mill consists of a pair of heavy backing rolls surrounded by a large number of small planetary rolls. The main feature of this mill is that it hot-reduces a slab to coiled strip in a single pass. The operation requires feed rolls to introduce the slab into the mill, and a pair of planishing rolls on the exit to improve the surface finish.
2. Feed the dry metal into the mill, applying snug (but not overpowering) pressure on rollers. 3. After rolling metal through the mill, flip the piece end to end before you roll it through again. You will get a more even roll. 4. Before passing the metal through the rollers, lower the rollers until you again have a snug fit (as in step 2). 5.

Definition of a Rolling Mill. Generally, a rolling mill refers to a machine used in metalworking works or projects to shape metal materials by passing them through a pair of rolls.. Similarly, these machines' main objective is to reduce metal materials' thickness and redesign them for use in different industrial projects.. Some of the by-products …
Two high mills: It comprises of two heavy rolls placed one over the other. The rolls are supported in bearings housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the rolls is adjustable. The rolls rotate in opposite directions and are driven by powerful electrical motors.
