John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup 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).
finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling ''broadside'' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"diameter workrolls through 28:1 gears to reduce the slab''s thickness by as much as 2½".
