Ironmaking Process an overview ScienceDirect Topics

2012-4-4  The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, typical reactions will take place.
