Research was focused on understanding the degradation kinetics of cold rolling oil used in the rolling mill at Tata Steel. Aged rolling oil leads to various surface defects. Ageing phenomenon is influenced through thermo-mechanical behaviour, oxidation, hydrolysis and presence of iron fines. Ageing of cold rolling oil in presence of iron fines was systematically performed at various temperature followed by thermo-mechanical wear tests. With variation in intensity of ageing, change in physico-chemical parameters and fatty acid distribution (FAD) within triglycerides could be observed. The impact of the controlled ageing on performance parameters like lubrication, evaporation kinetics and oxidative stability were also studied. Thermo-oxidative ageing depletes antioxidant concentration within the rolling oil resulting in rapid oxidation of unsaturated fats. This leads to rapid build-up of high molecular weight ingredients resulting in formation of fatty acid soaps or scum. The resultant scum negatively impacts the boundary lubrication and evaporation kinetics of rolling oil.

“…To the best of our knowledge, this is the first study toward investigating the solubility of fatty acid esters of a higher alcohol in SC-CO 2 . These esters have been studied for potential use as lubricants, , plasticizers, solvents, and flavors. , The solubility data are correlated by various semiempirical models such as the Chrastil model after testing its consistency with the model developed by Mendez-Santiago and Teja. The behavior of these systems is compared with other liquid solutes, especially other fatty acid methyl and ethyl esters.…”

The solubilities of butyl stearate and butyl laurate were determined in the temperature range of 308 K to 323 K and 313 K to 328 K, respectively, at pressures of 10 MPa to 16 MPa. The solubility of butyl laurate was higher than that of butyl stearate by almost an order in magnitude. Retrograde behavior was observed throughout the investigated pressure range. Semiempirical models such as Mendez-Teja, Chrastil, and other density-based models were used to correlate the experimental data of our work as well as several other liquid solutes.

“…Beyond that, the rolling force is also affected by the pH values. The alkaline lubricant shows lower rolling force compared with the others, indicating the better lubrication performance.The minimum rolling thickness is determined by the elastic deformation of the mill rolls and is related to the COF in the deformation zone, which directly represents the effect of lubricant 35. Minimum rolling thicknesses of the rolled strips without lubricant and with acidic, neutral, and alkaline lubricants are 0.375, 0.342, 0.327, and 0.309 mm, respectively.…”

The tribological performance and lubrication mechanism of graphene oxide (GO) aqueous lubricants with different pH levels on the strip surfaces during cold rolling were investigated. And triethanolamine (TEA) was used to adjust the pH levels of GO lubricants. The morphology of GO and physical characterization of GO lubricants were carried out. Four‐ball tribological tests and cold rolling experiments were conducted to obtain the tribological behaviors of GO lubricants on the strip surfaces. To figure out the lubrication mechanism, the surfaces of the rolled strips using GO lubricants were analyzed utilizing a series of experiments. The increase in the pH value of lubricants changed the intrinsic structure of GO, resulting in better dispersibility and wettability. The change of physical characteristics significantly improved the antifriction and antiwear properties of lubricants, and the alkaline lubricant (pH 9.0) exhibited the best lubrication performance. A diameter–height ratio (λd) applied by a calculation method was proposed to approximatively ascertain the lubrication regime during the cold rolling. The λd and the surface quality of the rolled strips indicated that the lubrication regime was the boundary lubrication when using the alkaline lubricant. Moreover, GO particles in the alkaline lubricant could repair the strip surface by mending effect and form the physically adsorbed layers. The layers prevented direct contact between rolled surfaces, further amending the surface quality of the rolled strips.
