Reduction of Iron Ore Pellets, Sinter, and Lump Ore under ...

23/03/2020  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 ...

Direct reduced iron - Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
