Roll Handling Systems and Equipment - AUTOMATIC HANDLING

Automatic Handling uses a platform of standard equipment for conveying rolls through the mill, depending on the project's layout and operational requirements. An electronic measuring station measures roll length, diameter, and weight, and sends the data to the mill system. The system automatically labels rolls with either a kick-up turning roller station or robotic labeler. After that rolls .

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).
