BF-BOF. (/BF-OHF) route: The steelmaking starts with the supplying from mining companies of the raw materials that are mainly iron ore (lump ore or fine ore)l, coal for coking, and mineral aggregates. When the raw materials arrive in the steel ▇▇▇▇▇, it starts an integrated process that consists in: i) Raw material preparation, with sintering or pelletizing raw materials; ii) Ironmaking, the production of hot metal with the prepared raw materials via Blast Furnace; iii) Steelmaking, the production of crude steel with the hot metal and recycled steel via BOF (or OHF). The BF-BOF route is the most used way for steel production and represents about 70% of the world steel production. A variation of this process is the use of a smelting reduction (SR-BOF) route, which is based on the combustion of coal for the reduction of iron ores with or without agglomeration, but which currently covers only 0.4% of world production of the steel43 and for this reason it won’t be deepened.
