The Nucleation of Co Bubbles in Molten Ironcarbon Drops Reacting with Oxidizing Gases
Laughlin, David E.
A theoretical representation has been developed for the supersaturation of molten iron drops with respect to carbon monoxide caused by the counter diffusion of carbon and oxygen. These theoretical predictions were compared with experimental measurements obtained using droplets, 4 to 6 mm in diameter at temperatures ranging from 1600 °C to 2000 °C under levitated conditions and with free fall. The agreement between the theoretically predicted and the experimentally measured limits for the onset of the carbon boil was very good, assuming that the effective diffusivity in levitated drops was about three times the molecular diffusivity. This observation is consistent with calculations of flow and mixing in electromagnetically levitated metal droplets.
