Abstract
The present invention is directed to a process for injecting iron oxide particles into a blast furnace through a pulverized coal injection (PCI) system, the injected particles causing a reduction in hot metal temperature, the injection process continuing and maintaining a target cooled hot metal temperature, the target hot metal tapped to provide a cooled hot metal charge in a BOF converter, the cooled hot metal charge decreasing BOF heat time and increasing BOF steel production.
