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).

The flat-only mills simply give you more width to work with. That allows you to make wider stock if you need it. Plus, without the grooves machined into the rollers, the rolls are a bit stronger, flexing less under load. That can give you more accurate sheet thickness, especially when rolling very thin stock, as well as often allowing you to ...
