摘要：

Blast furnace operation technology with pulverized coal injection (PCI) has been carried out in order to replace the maximum amount of metallurgical coke in the burden. PC burning has been studied and methods and designs for the intensification of its combustion have been developed within the raceway. Recommendations for optimizing coal grinding have been developed. Problems of PC distribution inside the circumference of the furnace were investigated. Compensating technology for changes in reduction, heat exchange and other processes under PCI have been developed.
