- Abstract
The development of a kinetic process model for the electric arc furnace (EAF) based on the effective equilibrium reaction zone approach is presented. The model combines kinetic expressions with accurate thermodynamic databases to predict the evolution of the mass, temperature and composition of the scrap, liquid metal, slag and gas phase during the process. The model addresses all the main phenomena occurring during the EAF process using empirical relations linked to process conditions: charge heating by arc and burners, scrap melting, C and O2 injection, slag-metal-gas reactions and post-combustion. The model can effectively reproduce measured endpoint temperature and composition of the slag and liquid metal in industrial EAF and illustrates the benefits of the hot heel practice. The model serves as a tool to assist in the optimization of the process operation conditions and in the design and evaluation of new process scenarios.
