【Abstract】 The PCI rate was only 50kg/t in 1996. In recent years,a series of measures such as reforming PCI equipment and process, improving the quality of burden and improving BF operation were taken. As result,PCI rate of BF was enhenced year by year. The productivity of 2.73t/ (m3.d),coke rate of 455 kg/t and coal rate of 124kg/t were achived in 1999.更多还原
