Simulation of the calcium treatment of aluminium killed steel

Based on results from microscopic analysis of steel samples, flow field calculations thermodynamic and kinetic considerations, a model has been derived that describes the evolution of the concentration, composition and size of the inclusions in the liquid steel during the injection of calcium. The mathematical solution of the model requires the incorporation of Population Balance Equations. The modelling results are compared to the actual inclusion composition in the steel from IJmuiden BOS2.
