Research on Lubrication Behaviors of Nano-TiO₂ in Water-Based Hot Rolling Liquid

Abstract:

In this paper, nano-TiO2 particles with an average size of smaller than 25 nm, were stable dispersion to water-based hot rolling liquid for steel strip under the effects of dispersant and ultrasonic. The stability of the rolling liquid with nano-TiO2 was characterized by sedimentation method. The tribological properties of the hot-rolling liquid doped with nano-TiO2 were evaluated by using a universal friction and wear tester. Besides, the lubricity of the water-based hot rolling liquid doped with nano-TiO2 for steel strip was evaluated on a hot-rolling tester by using the rolling liquid without nano-TiO2 for comparison. Results indicate that TiO2 Nano-particles as additive are stable dispersion to hot-rolling liquid with appropriate dispersant and process for more than 7 days, also have good friction-reducing, anti-wear, and cooling properties.
