Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. The BF-BOF route is used for 71% of steel produced, whilst the EAF route accounts for 29% of steel produced. The key difference between these routes is the material used to produce the steel and the plant configuration.

12.2.1 General. Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke. Metallurgical coke is used in iron and steel industry processes ...

2.1 Stage of Coal Processing. The PCI plant of the G blast furnace consists of three important sections. Raw coal handling—This consists of a coal ground-hopper that receives raw coal from the raw material yard through a dumper. From the ground-hopper, coal is conveyed through a series of conveyors and is stored in three raw coal silos.

To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.
