Statement: Metallurgical coke serves four critical functions in the blast furnace: (1) a reducing agent (converting iron oxides to iron via CO), (2) a fuel source providing heat, (3) a structural support maintaining burden permeability to allow gas flow, and (4) a carbon source for pig iron carburization. These combined roles require coke with high strength (CSR ≥60) and low reactivity (CRI <30), qualities achievable only from suitable coking coal in a slot oven process.
