Sponge Iron an overview ScienceDirect Topics

Sponge Iron an overview ScienceDirect Topics

Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H 2 ) which are generated through partial oxidation of coal (Reaction 3.3.1 ), reforming of methane by CO 2 /H 2 O (Reactions 3.3.2 and 3.3.3 ), or partial combustion of natural gas (Reaction 3.3.4 ).
