Inclusions — Modeling Studies
Proper control over the inclusion population size distribution is crucial for the production of clean steel. A model for the nucleation and growth of deoxidation inclusions, based on the Kampmann-Wagner model, is presented. The model includes diffusion and collision growth mechanisms. The model considers all solutes and alloying elements involved in the reaction(s), making it applicable to a wide range of situations. Initial results with alumina show a good fit to industrial sampling data. A study on the effect of different aluminum deoxidation methods (supersaturation, time between aluminum additions, type of aluminum addition) will be performed using the model.
