After exiting the finishing mills, the strip is carried down by a large number of individually-driven rolls through four to 12 banks of low-pressure, high-volume water sprays that cool the red-hot strip to a specified coiling temperature between 400 deg C and 900 deg C and into down coilers.Extension of mill stand opening of the entire mill; F1-F7: CVC ® plus and work roll bending; F1-F5: New drive systems in the finishing mill; New UNI plus coiler; New coil conveying system; Extension of water supply and treatment system; New X-Pact ® automation system for roughing mill, finishing mill, downcoilers, and coil transportation system

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 sheet can whip/hit into the roll surface and mark it. As a result, the following coil produced through the hot strip mill will have these bruises on the head end. If the marks on the work rolls are light, the defect only bruises the next coils surface and eventually …
