Control of size distribution of the ground ore, which makes up the pellet feed, is essential in the optimization of fired pellet most of the integrated steel works, the burden mix for blast furnace is decided as per the availability of the iron ore agglomerates like sinter and pellets.

Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines ( mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.
Relationship between chemical composition and hightemperature reduction behavior of sintered ore Fig. 1 shows the relationship between the dripping temperature Td (the temperature at the time when a dripping detector detects the first dripping of iron ore from a graphite crucible) and the composition of sintered ores and pellets.
a yearly production of Mt ironore pellets. Last year, in 2006, LKAB produced through this gratekiln process Mt ironore based pellet, which so far is the production record in million ton per year of the plant. The magnetite raw material are concentrated separately thorough the concentrating plant as illustrated in Figure 1.
oxygen from iron oxides and to convert iron oxides into liquid iron which can be cooled down to produce "pig iron" for further processing into steel. Iron oxide can be fed to the blast furnace in the form of raw ore (lump), pellets or sinter. In current ironmaking practice, sinter comprises up to 7085% of the total ferrous burden.
Dec 01, 2016· The objects of study is the iron ore, including concentrate, iron ore pellets etc. This work is a Desk study . As information sources used data of Rosstat, Federal customs service of Russia (FCS of Russia), sectoral and regional press, annual and quarterly reports of emitters of securities, Internetsites of companyproducers and consumers of iron ore products.
imperative to seek other sources of iron ore. This led to the need to investigate the possibility of utilizing at Delta Steel Company, the locally available iron ore at Itakpe, whose sinter grade had a total iron content of about 63% and a gangue in excess of 4%. This ore was originally conceived for use at the Ajaokuta Blast Furnace Plant
Fundamental pore formation mechanisms in iron ore sinter and pellets were investigated. The study was first conducted with tablets made from iron ore and limestone particles, with and without addition of coke, and the results were then tested and proved in real pellets made with a laboratory ball mill and in real sinter made with a sintering pot.
Iron ores for shaft directreduction feedstocks Determination of the reducibility index, final degree of reduction and degree of metallization
Reducibility is the case with which the oxygen combined with iron can be removed indirectly. The test is carried out by exposing a known weight of sample to 30/70 CO/N2 mixture at 900oC and noting down the loss of wt. It is always expressed in percentage dR % dt Generally a porous, low FeO, high CaO sinter gives high reducibility.
May 08, 2013· Pelletizing – Wikipedia, the free encyclopedia. Iron ore pellets are spheres of typically 8–18 mm (– in) to be used as . The raw material is rolled into a ball, then fired in a kiln to sinter the particles into a . as packed spheres in the blast furnace allows air to flow between the pellets.
Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's highgrade competent iron ore resources. ... if sintering fines are to be used for pelletizing ...

This device is a modification and extension of the original RF33 system to enable studying properties of ironcontaining raw materials.
• Good quality pellets can be produced at low SiO. 2 levels ( to %) whereas it is difficult to produce quality sinter at a SiO. 2 level of less than %, which helps slag volume reduction by 40to 45%. • Uniformquality superiorchemistry will enhance production by nearly 15 to 20% oftheirratedcapacity.
