Mathematical Model and Numerical Modeling of Scrap Melting Process Heating by Electric Arc in DC EAF

Based on detailed analysis of heat transfer of electric arc and scrap melting process, an integrated model was established. The model could be adapted in various EAF with different charge conditions. Using the model, the full process of scrap melting from the beginning to the melt end could be simulated, including moving and boring of the electrode and collapsing of the scrap simultaneously. The calculated results concurred with practical process and experience reasonably. The improved model would provide academic base for process optimization and operation control.
