Abstract
This paper presents an experimental study on the influence of an oxygen-enriched combustion atmosphere on the process of oxidation. Changing the composition of the oxidizing atmosphere exerts little effect on the oxidation at 800 °C, and CO2 and H2O serves as the primary oxidizing atmosphere in the range of 800–1200 °C. In a high-temperature environment, billets become badly oxidized despite the presence of a certain amount of reducing gas because of the high concentration of CO2 and H2O. This paper also presents the crystal microstructure of steel billet at different temperatures.
