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).
One disadvantage of a tandem mill is the high capital cost compared to that of a single stand reversing mill. For mills rolling thinner strip, bridles may be added either at the entry and/or the exit to increase the strip tension near the adjacent …

In the first full month of operation, the continuous rolling mill produced 9,000 tons of sheet steel. Three years later it was producing 40,000 (the original steel mills only produced 130-135 tons a week). All other major steel companies quickly adopted the invention and between 1927 and 1940, 26 continuous rolling mills were built.
Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold
