Using an AOD simulator workbench to support process control development

• The AOD (Argon Oxygen Decarburization) process is simulated with a model developed within the RFCS project OPCONSTAINLESS. The focus on the project has been on the influence of slag on the decarburization process. Here, a slag property is usually a parameter that is not used for process control, often due to the complexity of the slag system. The workbench, TimeAOD2, has been coupled with the Thermo-Calc software [1], giving the ratios of different slag phases and amount of liquid slag throughout the operation. The workbench gives the process manager an opportunity to see the outcome of different process layouts, control paradigms and raw material choices under different production conditions. A number of scenarios are outlined and different solutions evaluated. The simulation data is for some cases compared to operational data from AOD plants in Sweden.
