TL;DR: In this paper, the interaction between oxides formed on a work roll grade and the coefficient of friction established with a strip steel usually rolled by this roll grade was studied. But the authors focused on the formation and growth of the oxide scale.

TL;DR: In this article, a high temperature pin on disc tribometer is used to measure the friction coefficient and wear of hot working rolls. But the wear and friction behavior of the oxides appearing on the surface of the hot working rolling is not well known.

TL;DR: In this paper, an approach is proposed to assess the coupled effect of oxidation and friction on the overall tribological behaviour at high temperature. But this approach does not aim to reproduce strictly rolling conditions, but only to analyse the chemical and mechanical response of roll grades regarding thermal and mechanical stresses involved in hot rolling.

TL;DR: In this article, the authors describe a forged roll for use in the cold rolling industry and a method of producing a forged rolling as described, which has a steel composition, by weight, with 0.8 to less than 1% C, 0.6 to 1.6% Mo, more than 1.0 to 3.0% V, the remainder being Fe and impurities.

TL;DR: In this paper, a forging roll for use in cold rolling industry in the field of forging roll, and a method for manufacturing the forging roll is provided, which comprises a steel composition and a microstructure that comprises: tempered martensite with retained austenite at a ratio of less than 5% per volume.
