The Effect of Thermal Diffusion on Decarburization Kinetics

The influence of thermal diffusion on the kinetics of decarburization of Fe-Cr-C droplets with CO2-Ar gas mixtures was investigated. With incorporation of the effect of thermal diffusion, a new correlation has been proposed to express the decarburization kinetics of levitated droplets for flows in the range of Reynolds number between 2 and 100. A thermal diffusion factor of 0.228 was evaluated for CO2-Ar gas mixtures at 1873 K (1600 °C).
