Abstract
Fukuyama No. 4 blast furnace has been operated at 230 kg/t PCR and car ried a stable monthly operation of 218 kg/t. This was achieved thanks to the use of eccentric double lances with high combustion efficiency and the use of Hybrid Pelletized Sinter with superior reducibility and melting characteristics. This setting brought a reduction in fine cok e ratio in the deadman and improved permeability. The next evolution i s to achieve a PCR of 250-300 kg/t.
