“…Rutile is the most stable polymorph of TiO 2 at all temperatures up to its melting point at 1843 • C, which can be irreversibly converted from metastable phases of anatase or brookite upon being heated above temperatures in the range of 600-800 • C [31,32]. Glycerol is a colorless, odorless and viscous liquid that aids in enhancing the viscosity and wettability of nanolubricants [28]. SDBS is an organic dispersant with a linear structure (LAS) and hydrophilic group, which helps improve the wettability, dispersion stability and also the viscosity of the nanolubricants [30].…”

“…In our previous studies, the physicochemical and tribological properties of water-based nanolubricants containing P25 TiO 2 NPs were systematically investigated in terms of different loads, steel surfaces and temperatures [24][25][26]. The formulas of as-prepared water-based nanolubricants have been optimised, and therefore they exhibited largely enhanced lubrication performance in hot steel rolling [27][28][29][30]. However, all the fundamental research on water-based nanolubricants is only confined to the laboratory scale.…”

Eco-friendly and low-cost water-based nanolubricants containing rutile TiO2 nanoparticles (NPs) were developed for accelerating their applications in industrial-scale hot steel rolling. The lubrication performance of developed nanolubricants was evaluated in a 2-high Hille 100 experimental rolling mill at a rolling temperature of 850 °C in comparison to that of pure water. The results indicate that the use of nanolubricant enables one to decrease the rolling force, reduce the surface roughness and the oxide scale thickness, and enhance the surface hardness. In particular, the nanolubricant consisting of 4 wt % TiO2, 10 wt % glycerol, 0.2 wt % sodium dodecyl benzene sulfonate (SDBS) and 1 wt % Snailcool exhibits the best lubrication performance by lowering the rolling force, surface roughness and oxide scale thickness by up to 8.1%, 53.7% and 50%, respectively. The surface hardness is increased by 4.4%. The corresponding lubrication mechanisms are attributed to its superior wettability and thermal conductivity associated with the synergistic effect of rolling, mending and laminae forming that are contributed by TiO2 NPs.

“…Neem seed oil performed better in the experimental study of cold rolling of Aluminum strips than the coconut and diesel oil mixture [25]. Coconut oil showed the increased tribological and rheological properties when Cuo and Sio2 nano particles were used as additives [26]. Last non seizure load (LNSL value) of the emulsions was measured by four-ball tribo-tester, following the standard GB/T12583-1998 [1].…”

The rolling process had been used in every aspect of our life. Various types of sections like tee, angle, channel, railway track, sheets, foils of different mate-rial are made by rolling process. The quality of the product depends upon the various characteristics of rolling parameters. At the junction, the key role played by lubricants for saving energy and properties of the material in contact. Re-searchers are putting continuous efforts into the tribological analysis and developing new lubricants for the rolling process according to the material. The authors had reviewed the lubricants used in different rolling processes and found out a diverse range of lubricants. Various ecologically safe and effective lubricants had been reviewed. Lubrication performance testing tribometer for testing of tribological properties of lubricants had been reviewed. Hydrodynamic, mixed and boundary lubrication mechanisms had been found in different rolling conditions. The use of lubricants was found helpful in reducing power consumption in rolling and good quality products, hence the cost

“…Energy saving and environmental protection are being subjected to considerable concern in modern times [1]. Recently, great efforts have been made to minimise energy loss and environmental pollution in engineering applications [2][3][4][5]. Lubrication technology is one of the most useful approaches to solve these issues as the primary causes of energy loss in engineering fields are friction and wear [6].…”
