Wear, 1986
Abstract Unexpectedly high uniform rates of wear occur from time to time in concentrated lubricated rolling contacts having low slide-roll ratios. Such wear can occur under quite mild conditions and this poses a significant practical problem, especially in gears.

Wear of hot rolling mill rolls: an overview
Wear, 1994Abstract Rolling is today one of the most important industrial processes because a greater volume of material is worked by rolling than by any other technique. Roll wear is a multiplex process where mechanical and thermal fatigue combines with impact, abrasion, adhesion and corrosion, which all depend on system interactions rather than material ...

Friction and Wear at Tractive Rolling of Cylinders
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000AbstractBased on the fundamentals of tractive rolling contact mechanics, a method is described which is suited for calculating traction coefficients. Both the deformation and the adhesion component of friction are taken into consideration. It is demonstrated that the maximum traction coefficient is not a constant, but takes different values under ...

Lubrication and Wear in Rolling
2017Abstract Rolling is the process of reducing the thickness or changing the cross section of a workpiece by compressive forces applied through a set of rolls. This article emphasizes flat rolling and illustrates basic flat-rolling process used to reduce the thickness of a rectangular cross section.

Wear and fatigue in rolling contact
Wear, 2002Researches on wear and fatigue in rolling contact from a tribological viewpoint are introduced. Transmission of traction and accompanying microslip in the contact region play critical roles in these phenomena. First, a quantitative analysis of wear in rolling contact with microslip is introduced, and it is shown that a simplified microslip theory can ...

Abrasive wear of rolling bearings
Tribology International, 1981Abstract Various mechanisms of microslip are discussed; abrasive wear is considered the most important. An equation to predict the wear rate of rolling bearings is presented, based on previous work, and illustrated by an ...

A Study on Corrosion Wear of Cold Rolling Work Roll
Advanced Materials Research, 2013The MMS-2B wear machine was used to study abrasion wear of work rolls in cold rolling by simulating emulsion cooling during the cold rolling process. The work roll materials used were 4%Cr, same as those in industrial production. The surface SEM scanning photographs were taken every 30 minutes until the friction experiment finished, and erosive ...

Wear in cold rolling milling rolls: A methodological approach
Wear, 2019Abstract As a major steel production technology, cold rolling processes have a strong influence on the final quality of rolled products. Traditionally, cold rolling mill rolls present a controlled surface topography that is imprinted onto the sheet during forming and are often coated, particularly using hard chrome deposition.
