Highly efficient electric arc furnace process for continuous melting and smelting reduction was developed.
The corrected power consumption in which the reduction heat of iron oxide in the pellets was estimated as the equivalent heat for the melting of iron was improved with decreasing degree of metallization of the charged pellets. This improvement of the power consumption could be attributable to the enhancement of mixing in the bath by CO boiling due to the reduction of residual iron oxide in the pellets.
The apparent reaction rates of the bath components were estimated by considering their dilution curves.
