Katunin, L. Godik, M. Obsharov, N. Kozyrev, N. Timmerman] Conclusions: A technology for adding liquid pig iron to a DSP-10017 furnace has been developed, tested, and introduced commercially. The technology reduces the consumption of electric power by 44-55 kW·h/ton steel (to 406.3 kW·h/ton) and shortens the heat by an average of 10 min. The duration of the trial heats was 1 h, 51 min. Certain technological parameters of the steelmaking operation were determined. For example, it was established that the molten pig iron should be added only after complete melting of the scrap metal and that unit electric-power consumption during the addition should be within the range 230-320 kW·h/ton scrap. A total of 4-5 tons of iron ore (sinter) and 4-6 tons of lime should be added to the cold charge and the secondary scrap charge. The high SiO2 content of the slag makes it necessary to carefully discharge the slag over the sill of the working door after the liquid pig iron has been added.
