  • Hot Strip Mill - an overview ScienceDirect Topics

    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).

  • HOT STRIP MILL DOWN COILERS - Casey USA

    The strip enters the downcoiler from a pinch roll and is immediately formed around the mandrel using wrapper rolls. Unlike a traditional coiler, a hot strip mill downcoiler utilizes a series of rolls and sensors to maintain tight and well aligned coil wraps. The downcoiler eliminates telescoping coil sides and irregular wraps on a coil.
