Mathematical simulation of multiphase steelmaking reactions in the electric arc furnace
A mathematical simulator for the electric arc furnace has been developed. The main characteristic of this simulator is the integration of all steelmaking reactions having place at the main interfaces in the electric arc furnace. These reaction-interfaces include metal-slag, gas-liquid, slag-carbon, carbon-gas and slag-gas and solid-gas involving, therefore, a complex multiphase system just as the steelmaking process actually is. Additionally, the present simulator has the capacity to model the kinetic behavior of the furnace as affected by intermittent operations such as feeding of lime, reduced iron pellets and oxygen lancing. The simulator is provided with a model to calculate the dynamic changes of physical properties of the slag and uses them to calculate slag foaming properties. The integration of slag foaming index into the kinetic equations makes possible to describe the dynamic foaming index which changes according to the specific operating conditions of the furnace. The capability of this simulator to predict the process dynamics of the electric arc furnace (EAF) was tested in current heats in a furnace with a capacity of 220 tons demonstrating an excellent agreement between the predicted and actual process kinetics. This simulator can be used on-line, for process control and off-line for process design purposes.
