In twenty-first century some of these wastes are utilized in pelletization or by the introduction of micro pellets for sinter preparation. Blast Furnace. Blast furnace is generally known as the mother of all furnaces for iron making. Blast furnace requires special sized iron ore, coal / coke, and fluxes as a feed material.

Herein, the reducibility of the iron ore pellet, sinter, and lump ore in the BF shaft are focused on. The experiments are conducted isothermally with a blast furnace simulator (BFS) high-temperature furnace at four different temperatures (700, 800, 900, and 1000 C) for 300 min. The experimental atmosphere consists of CO, CO2, H2, H2O, …

A blast furnace (BF) is the dominant process for making iron in the world. The BF is charged with metallurgical coke and iron burden materials including iron ore pellets, sinter, and lump ore. While descending in the BF the charge materials reduce. The iron‐bearing materials should reduce fast and remain in the solid form until as high a …

Shaft furnaces use pellets (produced in the same way as pellets for the BF), or lump ore. Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4 ) from the siliceous gangue.
