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.

THE BLAST FURNACE - IRON PRODUCTION

2021-1-21  Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.

Electric Arc Furnaces vs. Blast Furnaces - Mbrashem

2017-8-22  The metal used with EAF is typically scrap metal or iron ore, but there are other possibilities. Controlling the temperature within the system is easier than a blast furnace, something that is important for efficiency. Another advantage of using the EAF process is that all types of steel can be created, including specialized metals and products.
