Iron Ore Pellet Furnace Reactions

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.

Iron ore pellets and Pelletizing processes – IspatGuru

Advantages of Pellets. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the same both in the blast furnace and for DR production. Pellets have good reducibility since they have high porosity (25-30%).

34 furnaces represent over 82% of the world DR iron production, with the two main processes being 35 MIDREX (see Fig. 1) (65%) and HYL-ENERGIRON (17%) [3]. 36 In a DR shaft furnace, a charge of pelletized or lu mp iron ore is loaded into the top of the furnace 37 and is allowed to descend by gravity through the reducing gas.

HOW A BLAST FURNACE WORKS - Foundry Gate

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

Reduction kinetics of iron ore pellets and effect of binders Submitted by: Subhram Keshary Singh (Roll No.-10404011) ... The reduction of iron ore by carbon is one of the most important reactions in iron making in blast furnace, rotary kiln and electric smelting furnace.

Pelletizing - Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64%-72% Fe and various additional material adjusting the stone composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.

Modeling of iron ore reactions in blast furnace ...

Iron ore (pellet, sinter and lump ore) is gradually reduced to iron in blast furnace. The reductions are a serial of heterogeneous gas solid reactions that take place from the top of the furnace and throughout the shaft region of the furnace.

Iron Ore Pellets - Iron Ore

One way to achieve this is to agglomorate the ore into pellets, which are round balls of concentrated ore. I will attempt to describe the iron ore pelletizing process below. In the palletisation plant, a suitable binder such as Bentonite is added to ground iron ore or iron ore concentrate which is …
