US5758530A - Hot rolling mill - Google Patents

A hot rolling line is constructed by a pair or a plurality of pairs of rolling rolls disposed opposingly on an upper side and on a lower side of a workpiece (1) to be rolled that is pinched in between the rollers. A descaling apparatus (5) has jet flow nozzles disposed so that two jetted flows, being liquid, gas or plasma, are opposing flows so as to collide with the surface of a strip on the ...

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 rolling is an important steel production process. Rolls in a hot rolling mill cost significantly and influence quality of products. Wear is a major factor of roll fault. So, it is very important to study roll wear at high temperature, although roll wear study in a real rolling mill is very difficult, especially for a hot rolling mill. To meet the need of practical production for the ...
