High Temperature Oxidation of Indefinite Chill Roll Material Under Dry and Humid Atmospheres
STEEL RESEARCH INTERNATIONAL(2016)
Abstract
In this paper, the isothermal oxidation of the indefinite chill (IC) roll is investigated by using a thermogravimetric analyzer (TGA) from 550 to 700 degrees C under dry and humid atmospheres. It is found that the oxidation kinetics follow a linear trend and the oxide scale consists of two layers after the oxidation in dry air but three layers in humid air above 600 degrees C. In dry air, the graphite is covered by the oxide scale above 650 degrees C. The water vapor accelerates the oxidation of the matrix and the graphite. The graphite is covered by the extension of the oxide scale above 600 degrees C in humid air. The as-treated samples are examined with SEM and XRD, while the kinetics is based on TGA results.
