Blast Furnace an overview ScienceDirect Topics

Integrated coalfueled steel mills accounted for ∼60% of the 1.4 Gt of global steel produced in 2008, consuming 15–18 GJ per tsteel produced and emitting a global average of ∼1.4 tCO 2 per tsteel produced. In the first stage of the steelmaking process, highgrade coal (anthracite) is used to fuel a blast furnace in which iron is extracted by reduction from the ore hematite (Fe 2 O 3
