In the oxygen steelmaking process, time of refining of metal droplets and the surface area contributing to the slag-metal reactions are controlled by the bloating behavior of the droplets. The bloating behavior is determined by the decarburization kinetics. So, understanding the fundamentals of the decarburization process is essential to modeling the droplet contribution to refining. A study of decarburization has been performed with varying carbon concentrations and mass of metal droplets. The bloating behavior has been observed to be present for carbon level as low as 0.5% to 4.5%C. The reaction is found to control electrochemically at the end stage.
