Roll stands, which hold pairs of rolls, are grouped to form rolling mills, which can quickly process metal, typically steel, into products like structural steel (Ibeams, angle stock, channel stock, and so on), bar stock, and rails. The rolling mill divisions of most steel mills convert semifinished casting products into finished products.

Backup rolls are the main tool in a fourhigh rolling mill; the rolling forces applied in load cells promote the fatigue of the material due to mechanical contact between backup rolls and work rolls. This work investigated the causes of recurrent failures in backup rolls, with cracking always initiated on the surface of the roll body and finishing in the main radius between neck and roll body.

Here are a few of the main types of rolling mills: Continuous rolling mill. Sheet metal passes through several rolling stands, each pressing the metal thinner. Cluster rolling mill. A cluster of metal rolls are lined up to be thinned out. An example of a cluster rolling mill would be a 20High Cluster Rolling Mill.

The Planetary Mill is a medium output mill for rolling of steel strip. Its output is less than continuous mills of many stands but more than the reversing twohigh or the threehigh mill. This mill can be used to roll all metals but it is especially useful for those which have low ductility. All forces in the mill are compressive so there are ...
