A CASE STUDY OF MATERIAL AND ENERGY BALANCE OF STEEL MAKING IN ELECTRIC ARC FURNACE FROM DRI

Abstract

The contribution of this thesis is to study the effect of the sponge iron on the energy consumption. DRI is considered one of the most important factors affecting energy. To study that effect, mass and energy balances as well as exergy analysis were implemented in order to deduce the amount of all the energies supplied by electrical or resulting from the combustion of methane or from the oxidation and reduction reactions. Then those energies were described by equations to study its change with the DRI change.
