iron ore. Fig. 3.3 : Effect of size of ore on degree of reduction. Iron ore and agglomerates as charge material should be resistant to abrasion. If they break into finer fractions due to impact, abrasion, compression and volume change within the furnace, the smaller particles result in choking of voids thereby affecting reduction and productivity.

Laboratory studies of chemical kinetics and heat transfer in the reduction of iron ore/carbon (coal) mixtures in various forms are reviewed. Therefore, the rate-limiting steps, which are of critical importance in process development, may be identified or suggested for a given set of conditions. Commercial operations using rotary hearth …
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
In the case of fluidized-bed reduction of iron ore, earlier works [8, 9, ... also reported agglomerates formed due to sintering of reduced iron, and nano/mircostructure on the particle surface had a promotive effect on particle agglomeration. Therefore, the sticking tendency depended strongly on iron precipitation of particles.
iron carbon agglomerates (ICA), iron coke or ferro coke) in BF is considered to be a low carbon technology that min-imizes the modification of the existing BF ironmaking system and can realize industrialization. Iron coke is the product of co-carbonization of iron ore and coal. Iron ore is reduced to metallic iron in the carbonization process,
Iron ore pellets and their breakage behavior is investigated in ... limestone and return fines are converted into agglomerates of suitable size for charging into the blast furnace. Agglomeration is achieved by forced draught combustion of an admixed fuel, in this case coke. Superficial melting leads to adhesion between particles (ISO 11323, ...
