HOW A BLAST FURNACE WORKS
The Process Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe2O3) or Magnetite (Fe3O4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any …

Blast furnace ironmaking and its ferrous burden quality …
11· 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. It produces approximately 68% …

Iron processing
Crushing As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions by passing it over sieves through …
