Changing dynamics of iron ore pellets industry - Blogs ...

12-09-2018  Steel is made predominantly by two routes: Blast Furnace – Basic Oxygen Furnace (BF-BOF) route and Electric Arc Furnace (EAF) route globally, both these processes require iron ore to be fed in BF or DRI units. Globally, around two billion tonnes of iron ore (average 62%) is used in the form of lumps/sinter/pellets to produce steel.

30-01-2020  with a blast furnace simulator (BFS) high-temperature furnace at four different temperatures (700, 800, 900, and 1000 C) for 300min. The experimental atmosphere consists of CO, CO 2,H 2,H 2O, and N 2 simulating the conditions in the BF shaft. It is found that lump ore has lowest reduction rate in all test conditions, and at lower temperatures iron ore pellets reduce faster than sinter,

The Use of Coated Pellets in Optimising the Blast Furnace ...

The amount of coating applied to blast furnace pelletscan be accurately controlled, within 0.05 wt% in the slagformer oxides of the pellets. The coating was found to stay on the pellets well, evenafter storing, transport, handling and on-size screening.This was verified by chemical analyses as well as by mi-croscopic studies.

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.
