“…The rolling process plastically deforms the ingots/billets into the appropriate required shape and size. The process necessitates strong compressive pressure with suitable temperature and friction [4,5]. The rolling mill continuously operates for a timely and constant supply of rolled products.…”

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.

“…Among them, sheet material processing methods have received a lot of attention from researchers due to their widespread applications in engineering and industry [13]. These methods include rolling [14], deep drawing [15], hydroforming [16], accumulative roll-bonding [17], constrained groove pressing [18], repetitive corrugation and straightening [19], friction stir processing [20], etc [21][22][23], among which, the continuous techniques are used extensively in the production of metallic sheets and foils. It is worthy to note that more than 70% of metal products are processed through rolling techniques in the world [14,24].…”

Aluminum alloys, especially the 5000 series, have drawn the attention of the transportation industry due to their lightweight and consequently reduced fuel consumption. In this regard, one of the major problems of this alloy is its low strength and ductility that can be solved using rolling and post-annealing. Accordingly, the present study concentrates on this issue. Microstructural images showed that the rolling process develops a lot of tangled and trapped dislocations in the sample, which gradually lead to the formation of dislocation bundles and networks. Subsequent annealing can produce a more homogeneous structure with clear grain boundaries and low dislocation density in the inner region of the grains. However, grain refinement efficiency through rolling is retained even after annealing. Initial and rolled Al5052 with the maximum intensity of 2.87 and 6.33 possess the lowest and highest overall texture. Also, post-annealing decreases the texture intensity to 6.33 and 4.87 at 150 and 200 °C, respectively. In this context, deformation texture components strengthen considerably after the rolling process due to the formation of shear bands, and they slightly weaken during heat treatment. Although the initial annealing of the as-received material does not cause discontinuous recrystallization during rolling, it may facilitate the material recovery before rolling. Post-annealing was found to decrease the improved effect of strength by rolling and increase the negative influence of ductility due to the inhibition of dislocation strengthening. The results showed that both dislocation density and the precipitation of Mg atoms are influential for electrical resistivity.

Improving Quality in the Process of Hot Rolling of Steel Sheets

The hot rolling of steel sheets is a highly energy-intensive process. There are technical and operational issues associated with this process, and the causes of these issues can be various. This study involved analysis of one issue that has a great influence on the resulting surface quality of rolled sheet metal: rolled foreign material. After the sheet cools, rolled foreign material tends to fall off and a hole then remain on the surface of the sheet. This paper focuses on the search for the root causes of the occurrence of foreign material rolling. The basic categorization of the causes of this issue was performed by experienced long-term operators. The 4M method (man, machine, method, and material) was used to categorize the causes. Pairwise comparison was used to verify the result. Using energy dispersive spectroscopy analysis, the origin of the foreign material was identified. The analysis confirmed that the foreign material was not derived from the primary material. Further research showed that the cause of the issue was the guide rulers, which are a structural part of the rolling mill. Measures were taken to significantly reduce the incidence of the problem, which also had the effect of reducing financial losses, which fell by a third in 18 weeks. In the future, it will be necessary to make design changes (modernization of the rolling mill), which will, however, require more financial investment.
