Modern blast furnaces range in size from 20 to 110 metres (70 to 360 feet), have hearth diameters of 6 to 15 metres (20 to 50 feet), and can produce from 1,000 to about 15,000 tons of pig iron daily. Steelmaking accounts for about 8 percent of global greenhouse gas emissions—the most of any industry—and these emissions contribute to global warming.

50.3.1.1 Example—Burden Distribution Change. Iron ore sinter /pellets are redirected from the wall of the blast furnace to the center using the bell-less top charging equipment. The top gas utilization (TGU) improves from 47.5 to 49.0% (an increase of 1.5%) due to better contact of the ferrous burden with the CO-rich gas in the furnace center.

What is a Blast Furnace? Steel Foundations A blast furnace reduces iron ore into pig iron, also called hot metal, in the ironmaking process, which is the chief ingredient used in the steelmaking process. A blast furnace primarily utilizes metallurgical coke, iron ore, and “burnt” lime to produce pig iron.

2021-2-20 Among iron-bearing materials, pellets are an important feed material for the blast furnace operation. However, pellets exhibit swelling inside the blast furnace due to the high temperature inside the furnace, which causes dissociation of pellets and if swelling index is not controlled properly, it gets crumbled into fragments.

2021-8-31 Iron ore pellets are commonly used as iron burden materials in blast furnaces. The pellets are small and hard iron ore balls. Their diameter is usually 10–16 mm. The pellets are hot-bonded in order to provide sufficient mechanical strength. A high iron content and a low gangue content is favourable for blast furnace pellets [ 17 ].
