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).

By the end of seventeenth century, hot mills using grooveless ("flat") rolls were being employed to reduce the thickness of cuboids into sheets. At the present time, hot rolling mills can produce up to one mm thickness, but the usual minimum thicknesses are limited at 1.5 mm especially when rolling velocity reaches 15 m/s and over.

The new configuration of Hot Mill allows to achieve higher productivity and state-of-the-art quality on the produced strip. Moreover, thanks to the larger motor power and to the exceptionally high torque available at the rolls, a substantial reduction in the number of rolling passes necessary to achieve the final target is being experienced.

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
