Apr 04, 2012 · For example, for the ironmaking process, iron ore (sinter or pellet), coke, coal, and air blast are charged separately, but inside the BF they are mixed together, and reactions occur, such as combustion, heating-up, carbon solution loss, ore reduction, decarburization, and desulfurization of molten iron. Finally, the hot metal and molten slag are formed and tapped out periodically.
