Steelmaking Process - an overview | ScienceDirect Topics

It can be seen that blast furnace–BOF steelmaking route consumes 19.8–31.2 GJ energy per ton crude steel, while the EAF route using 100% steel scrap consumes 9.1–12.5 GJ energy per ton steel.For the integrated steel production with blast furnace–BOF route, responsible for almost 2/3 of the total steel production, about 75% of the energy arising from coal is attributed to the blast ...

Metallurgical coal | BHP

Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth's crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.
