(DOC) Optimization of Cold Rolling Mill Parameter to ...

Reversing mills are generally used for smaller scale production of the cold rolled products. 2. COLD ROLLING MILL: The function of rolling mill is to reduce ingoing strip at room temperature by 50 to 90%. The reduction of strip thickness is caused by compressive stresses in contact region between work roll surface and strip.

Hot Strip Mill

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).
