Iron Ore Pelletizing Process: An Overview
In the blast furnace, iron is reduced and melted and the most common product is liquid iron called hot metal. In direct reduction, iron remains in solid state and the product is the socalled direct reduced iron (DRI). Generically, the iron ore products for ironmaking can be classified as shown in Table 1 . Pellets are balls formed by rolling moist concentrates and fines iron ores of different ...

· Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents and solid fuel (coke).
Appliion of Biomass Pellets for Iron Ore Sintering ...
In particular, as revealed by comprehensive analyses, biomass can be used as fuel for iron ore sintering. In this study, we investigate the use of some raw and pyrolysisprocessed biomass pellet types, namely wood, sunflower husks (SFH), and straw, for iron ore sintering. In the experiments, the pyrolysis temperature was set to 673, 873, 1073, and 1273 K, and the proportion of biomass in the ...

· Carbothermic reduction of composite pellet (iron ore concentrate and coal or coke) at oxidizing atmosphere was experimentally studied by Kasai, Misra, and Iguchi.[11–13] The results reported the reduction experiments of composite pellets in a combustion packed bed, and the prereduced product was manufactured. Therefore, it is a feasible way to produce prereduced product by sintering ...
Use of Iron Ore Pellets in Blast Furnace Burden – IspatGuru
· Use of Iron Ore Pellets in Blast Furnace Burden ... The resultant high grade ore is in the form of fine particles, as small as mm or less, which are not suitable for sintering. This issue led to the development of pelletizing of these fine particles. Pelletizing plants today play an important role in an era when the global reserve of high grade lump ore is shrinking. The plants promote the ...

Pelletizing Process
that are charged into a blast furnace include lump ore, sintered ore and pellets. The ones charged into an EAF include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are ...

Sintering raw mixes withahighproportion offines(<150 m) deteriorates the operationofthe DwightLloyd sinter machine, and for that reason pelletizing is the best method for treating this kind of material. The formation of liquid phases, which agglomerate the iron ore, in pellets is achieved by an external source of ...
Pelletizing
Sintering. In order for the pellets to achieve their final properties, they have to be sintered, which means that the pellets are heated so that the iron ore particles partially melt together. After the pellets have been sintered at approximately 1,250°C, they can cope with a load of up to 250 kg. Cooling
