Plant level implementation of a model for real time tracking of composition changes to steel, slag and inclusions during ladle processing

The Ladle Metallurgy Furnace is used for adjustment of chemical composition and temperature, and control of tiny particles called inclusions. Controlling inclusions is carried out by adding calcium to modify the solid alumina or magnesium aluminate inclusions to less harmful liquid inclusions.
During ladle process, reaction of top slag, steel and inclusions occur simultaneously. Therefore, establishing a model to describe ladle process is indeed a challenge. The author developed a model to predict the chemical composition changes in molten steel, slag, and evolution of inclusions in the ladle during Ca treatment. The result of calculations was found to agree well with industrial heat data. However, the model is not in a form that can be used as a real-time tool. The overall objective of the current project is to develop a version of the model that will be sufficiently fast to use for real-time processing. Secondary objective is to calibrate the model for the ladle used in the KOBM stream at ArcelorMittal Dofasco
