“…Regardless of the rolling type, the lubricant mitigates friction and wear rate [56]. Lubrication reduces the real area of contact by confining lubricant at interfaces and lessens shear strength at the contact interface [87][88][89][90]. The attempts to enhance the anti-friction properties of traditional rolling lubricating fluids, the studies prompted the application of nanoparticles as an additive [91].…”

The purpose of the present article is to dispense an extensive review of research works performed to observe the impacts of nanoparticles tribologically and rationalise the use of nanoparticles in metal rolling lubrication. The results of past experimental research were analysed based on tribological behaviour, lubricant characteristics, and rolling quality. Improvements in tribological behaviour, rolled surface characteristics and mechanical strength were illustrated in the present work. A specific concentration of nanoparticles in the base lubricant was discovered which provided beneficial outcomes. The oxide scale formed as an inevitable byproduct is suppressed by the nano-application. The nanoparticles served better in the rolling process in terms of temperature control due to the enhanced thermal conductivity of the base lubricant. The article advocates for the adoption of nanolubrication in replacement of traditional lubricating fluids in the rolling process. The article lastly presents future challenges and the potential of nanolubricants in engineering applications.

“…In order to ensure precision, four conditions had to be met while measuring the actual wear data: (1) the roll must be maintained cold for 24 hours or more to ensure that the roll temperature on the surface, inside, and outside is essentially the same, thereby effectively eliminating the effect of thermal deformation on roll wear data and temperature change on roller front diameter; (2) the measurement data after rolling must be taken twice in the directions of maximum and minimum, and the average value must be taken to reduce data deviation; (3) before measuring the roll wear, we must carefully remove any oxide and other adhesions from the roller surface; (4) the level roller bearings at both ends must be adjusted to ensure that the measurement center line and the roll axis are coinciding [7,12,13].…”

This paper presents a novel approach to developing a work roll prediction model that takes into account both the mechanism and condition influences on work roll wear. This was accomplished by conducting an analytic calculation of work roll mechanism influence, constructing a work roll wear model, and combining the wear mechanism with actual wear data. The resulting model is applicable to both symmetric and asymmetric wear of the work roll, and experimental results showed that the relative error between measured and predicted values was less than 5%, with a maximum error of below 15%. This level of accuracy is sufficient for predicting roll wear and lays the foundation for improved strip shape control and roll design. Furthermore, this approach has the potential to generate significant economic benefits and has wide-ranging applications.

“…As so, a variety of HSS have been developed and applied to manufacture work rolls. What is more, rolling lubrication has also been widely adopted in rolling process, which has significant effects on the reductions of rolling loads, friction coefficient and oxidation rate, resulting in obvious alleviation of roll wear [3,7,8]. Furthermore, the optimization of roll contour is extensively used to improve roll wear.…”

Work roll wear is a key factor that affects the quality of the steel strip during the hot rolling process. With the demand for the same width steel rolling, work roll severe 'U' groove type wear appears. In this paper, it is found that work roll surface cannot reach their full potential with the conventional work roll shifting mode, which lead to severe and uneven work roll wear. As a solution, a sinusoidal cyclical shifting mode is proposed, and its effects on roll wear are investigated. As a result, work roll wear can be relocated from the central area to the sides. In the meantime, contact stress peaks reduce significantly in work roll mid and later service periods with a more even wear contour. Moreover, roll fatigue can be improved, while the adjustment range of equivalent work roll crown is not changed with the sinusoidal shifting mode.
