Mathematical models, algorithms and software for dynamic simulation of leadle treatment technology

The original software for dynamic simulation of ladle treatment of steel was developed. Physical and chemical models based on the conservation law of mass and energy, as well as the principles of non equilibrium thermodynamics were used. All the stages of the process (zones) were taken into account in this software. This software takes into consideration input data such as: ladle equipment facilities, initial temperature, slag and metal mass compositions, input time and mass of additives, blowing, electrical and time regimes, thermodynamic database, thermal, physical and chemical databases for additives and inert gas, production database (for statistics). This software allows us to calculate the main characteristics of the ladle treatment such as temperatures and chemical composition of slag and the steel melts. For validation of the software, the results of ladle treatment of real heats of steel and sampling control results were used. This software can be used in online calculations and control of process parameters during ladle treatment, simulation and optimization of ladle treatment technology, teaching and training of steelmaking staff.
