Ironmaking Process - an overview | ScienceDirect Topics

4/4/2012· 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 ].

Iron and Steel Manufacturing

In the BOF process, coke making and iron making precede steel making; these steps are not necessary with an EAF. Pig iron is manufactured from sintered, pelletized, or lump iron ores us-ing coke and limestone in a blast furnace. It is then fed to a BOF in

THE BLAST FURNACE - IRON PRODUCTION

The stock level is constantly ‘topped up’. Molten iron ore is ‘tapped’ at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole. Although generally regarded as waste, it is used in road making.
