In order to melt pre-reduced iron pellets with high efficiency the continuous melting and smelting reduction furnace, a kind of electric arc furnace, was developed.
According to results using pre-reduced iron pellets with various levels of metallization ratio, it was observed that corrected power consumption in which the reduction heat of iron oxide in pellets was estimated as the equivalent heat for the melting of iron was improved with the decrease of the metallization ratio of pellets.This was due to the CO boiling, which occurred in the bath as a result of reduction of iron oxide in pellets and played very important role for the effective utilization of electric power.
Apparent reaction rates of Si and Mn were estimated by considering their dilution curves. The effect of bath mixing on their rates was considered.
