The Effects of High-Speed Steel Roll and Lubrication on Work
Work rolls in the hot strip mill withstand extreme service conditions, especially when electrical steels are rolled, resulting in severe roll wear and fatigue. High-speed steel (HSS) work rolls and rolling lubrication are applied to the mill to improve roll wear and fatigue. Tests show that HSS work rolls manifest good performance in wear, fatigue and …
Roller Mill
Roller mill is a type of grinding equipment for crushing materials by pressure between two or more rolling surfaces or between rolling grinding bodies (balls, rollers) and a track (plane, ring, and table). The roller mill with several grinding rollers as working components rolls along the grinding ring or the grinding table to crush the ...

Analysis of a Progressive Failure of a Work Roll in Hot Strip Mill
In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the service life of rolls. The hot strip mill referred here …

by the rolling elements. The over-rolling creates indentations in the raceways († fig. 1). Hard particles may cause inden-tations with sharp edges. When the area around the indentation is then subject to c yclic stress due to normal over-rolling by the rolling elements, surface fatigue is initi-ated and the metal will start to break away
