Reduction of Iron Ore Pellets, Sinter, and Lump Ore

2020-3-23  A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron‐bearing materials separately, which leads to a layered structure. The iron‐bearing materials consist of iron ore pellets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H 2. In the ideal situation, iron‐bearing materials reduce

Limiting phenomena related to the use of iron ore

Abstract Most of the iron in the world is produced using a blast furnace process, which has iron ore (iron oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the ...
