As indicated in Fig. 2.1, the raw materials used in the BF-BOF system include iron ore, coal, fluxes (mainly limestone and dolomite), recycled steel scraps, and alloys.On average, this process uses approximately 1400 kg (3086 lb) of iron ore, 800 kg (1764 lb) of coal, 300 kg (661 lb) of flux, and 120 kg (265 lb) of recycled steel to produce 1000 kg (2205 lb) of crude steel.
Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. Variations and combinations of production routes also exist. The BF-BOF route produces steel using raw materials such as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF-BOF route.
