The Kinetics of CO Formation During Coupled Reactions Involved in the Refining of Steel-understanding G (CO)
The formation of CO bubbles at the metal surface during the refining of pig iron from the blast furnace (de-S and simultaneous de-S/de-P) and during steelmaking is an important phenomenon because it influences the kinetics of the reactions. The mechanisms of CO bubble nucleation, growth, rise, and detachment are described. Analysis and modeling of these processes suggests that even during rapid bubble formation a significant fraction of the metal surface will consist of metal-slag interface, which is necessary for the transfer of impurities like phosphorus and sulfur to the slag phase.
