Blast furnace ironmaking and its ferrous burden quality …

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 iron-bearing raw materials, and coke and pulverized coal as fuel and reducing agents to produce hot metal with consistent quality for the BOF process.

What's the Process of Iron Smelting?

There are two kinds of slag formation in blast furnace. When smelting with ordinary acid ore, the flux is loaded into the blast furnace in the form of limestone, and the Cao in the flux can not be in close contact with the acid oxides in the ore. therefore, the slag initially formed is mainly fe2sio4 formed by SiO2, Al2O3 and a part of reduced FeO.
