Consider the hot rolling of a low-carbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30% using work rolls of 800 mm diameter, rotating at 50 rpm.
Extra Heavy Duty Adjustable-Height Steel Tables. With a thick steel frame and a capacity of at least 10, 500 lbs., these welded tables are our strongest and most durable adjustable-height tables. They can be configured for either seated or standing tasks.
In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (equal to or more than 2 stands) and reductions take place successively. The number of stands can range from 2 to 18. Tandem mills can be either of hot rolling or cold rolling mill types. Fig 2 Types of rolling mills
Rolling Mill Stands are used to control the outer diameter of the pipe during the elongation and diameter finishing processes. Mill Stands in rolling mills consist of several components and systems, all of which are subject to high temperatures, high loads and extreme conditions.

The invention focuses on improvements to cantilevered roughing, intermediate and finishing rolling mill stands, primarily for long products. A basic improvement to 2-high and cluster mill stands includes mounting of the rolling bearings upon a stationary cantilevered arbor directly under the roll ring, eliminating heavily-loaded main reaction bearings within the stand housing …
The conventional rolling mill stand besides the roll stand consists of mill spindles, a pinion stand, a gear reducer and a motor. In case of constant pass line, the roll stand slides on the surface of the sole plate. Housing less mill stands are a pre-stressed stand which is more rigid than the conventional stands.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
