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 high-impact strip drying system ensures a safe rolling process up to the maximum rolling speed. The fully automatic roll change by robot has substantially shortened rolling mill set-up times and, even more importantly, permits contact-free roll changing within a very short time without damaging the rolls.
