The integrated iron and steelmaking route involves blast furnace (BF) ironmaking followed by basic oxygen furnace (BOF) steelmaking. The BF uses sinter, pellets, and lump ore as ironbearing raw materials, and coke and pulverized coal as fuel and reducing agents to produce hot metal with consistent quality for the BOF process.
