A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.

Our experience with cold rolling oils dates back more than 60 years when we blended our first product for a Sendzimir Mill rolling stainless steel in Pennsylvania. Our products today are sold world wide for all types of metals, including carbon and stainless steels, titanium, copper, brass, bronze, beryllium copper and aluminum alloys.

Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

*) A Sendzimir mill is a mill with small diameter work rolls, each backed up by two rolls of larger diameter which are in turn jointly backed up by a cluster of three rolls. This mill configu-ration is often used for height-strength- and stainless steel. Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the
