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).
The mill roller is mainly composed of a roll body, a roll neck and a shaft head. The roll body is the middle part of the roll, which actually participates in the rolling of the metal with a smooth cylindrical or grooved surface. There are steel rolls, cast iron rolls, alloy rolls, ceramic rolls, etc, according to the roll material. Depending on ...

Ball mills create an environment of high wear. This wear occurs during the crushing of various materials to reduce their particle size. Due to this environment of high wear abrasion, significant amounts of metal alloys are consumed on both the grinding balls and the shell itself. Therefore it is desirable to have alloys that have high wear rates to reduce the turnover and cost .
