Abstract

To obtain a low cost, environmentally friendly and effective lubricant, a novel nanoTiO₂ additive oil-in-water (O/W) lubricant for hot steel rolling has been developed. Based on the contact angle, tribological and hot rolling tests, the performance of the nanoTiO₂ additive O/W lubricants was evaluated and discussed. The results show that the strongest adhesion force between the nanoTiO₂ additive O/W lubricant and the work roll is obtained after addition of 4% nanoTiO₂ additive in the 1% O/W lubricant. The nanoTiO₂ nanoparticles can reduce coefficient of friction (COF) and rolling force, and enhance the surface quality of the hot-rolled product. The lubrication mechanism of nanoTiO₂ additive O/W-based lubricant has been proposed.
