| Abstract: | The key to increase the PCI rate is to improve the permeability and keep good heat condition. The PCI rate of 350m3 BF in Jinan Iron and Steel Corporation has made great progress by taking such measures as reconstructing equipment, optimizing selection of injection coals, improving BF slag characteristics, adjusting operational parameters, the increasing oxygen content and blast temperature. In June 2003, the average PCI rate for 350m3 BF reached 153kg/t while the pulverized coal rate for No.4 BF reached 181kg/t and the coke ratio reduced to 330kg/t. |
