| Abstract: | The reformation of coal pulverization,characteristics of PCI process and smeltimg practice of BF with PC and O_2-enrichment are introduced in this paper.A multi-pipe dense phase transformation technique is used in the process and the injection rate can be controlled for single tuyere. This process can work with pulverized bitumenite.Some measures corresponding to the operation changes of BF with PCI are adopted and good results in raising productivity and saving coke have been obtained. |
