Development of a new parameter for predicting hot metal desulfurization efficiency

Over the last decades, capability of a desulfurizing mixture to remove sulfur has been widely studied. The hot metal desulfurization efficiency represents percentage removed from bath and development parameters that predict process is fundamental for selecting best without need experimental tests. Therefore, this research aims develop new parameter efficiency, which was called factor (FDeS). Desulfurizing mixtures CaO-Fluorspar CaO-Sodalite systems were used purpose. phases present in heating at 1400°C as well liquid solid determined by ThelmoCalc software. These data construction. Experiments carried out an electric resistance furnace with mechanical stirring. Different these added molten 1400°C. Sampling made measure content variation time. It possible apply proposed determine influence on efficiency.
