The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron ,
Fraction of 2 mm to 5 mm should be as higher as possible for better sintering process Normally we get iron ore fines that is having 100 mesh (- 015 mm micro fines) minimum of 25 % and 15 % to 20 % +8 mm size We are planning to install on-line screening to separate + 8 mm size from the lot and the
Iron ore pellets are spheres of typically 6–16 mm (024–063 in) to be used as raw material for blast furnacThey typically contain 64%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets Typically limestone, dolomite and olivine is added and Bentonite is used as binder The process of pelletizing combines mixing of .
Sinter plant The most important raw material needed to produce steel is iron ore But, as is the case with coal, iron ore cannot be used directly in the blast furnace That is why we first have to create sinter How does this work? In our sinter plants (Ghent), we bake a mixture of fine iron ores, ferruferous recuperation materials and flux
the basic materials Iron Ore classification – The basic material for iron and steel production is iron ore or ferrous scrap Iron ores are classified based on shape and volume Iron fines have a majority of particles with a diameter of < 475 mm; iron lump ore has a majority of particles with a diameter of >475 mm; iron pellets are a
Iron Ore is the most important raw material needed to produce steel However, it cannot be used directly in the blast furnace That is why sinter is created that helps converting iron into steel Rashmi Metaliks has its own Sinter Plant set up at 2007 to have a complete control over the quality of materials used in the steel production process
Nov 23, 2017· In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often .
CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING R P Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in
The iron ore blend for sintering depends to a great extent on ore properti It is hard to determine the final sinter reducibility from the reducibility and ratio of single iron ores in a mixture
With decreasing or increasing the upper size of the iron ore fines the mean size of the iron ore fines will change With decreasing the coarser size fraction increases the finer size fraction in iron ore fin 22 Sintering For each individual iron ore fines of different mean sizes, pot grate sinter experiments were carried out by preparing
(vii) iron ore fines: same source iron ore used for all experiments ( 2 10 mm) (viii) heat input for ignition: 1200 uC Microstructural investigations The sinter samples obtained from each experiment were crushed in a jaw crusher to 1 mm size The sinter grains of y 1 mm ,
Sep 24, 2017· Sinter is an agglomerated form of iron ore fines in which ore particles are bonded by applying incipient fusion at the contact surfaceformation of diffusion bonds through recrystallization and crystal growth of hematite and magnetite ,which keep .
The ingredients – iron ore, coke and limestone fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnac Making iron
If one iron ore is good for sintering process as per mineralogy but not suitable for pellet plant why? in the respect of Mineralogy? , while the fine size and high quality of the iron ore is .
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process Sinter is the primary feed material for making iron and steel in a blast furnace

Technical Support Document for the Iron and Steel Sector: Proposed Rule for Mandatory Reporting of Greenhouse Gases 1 INDUSTRY DESCRIPTION This section summarizes the processes and major emission points of greenhouse gases for taconite iron ore processing, coke plants, sinter plants, blast furnaces, basic oxygen furnaces.
Oct 27, 2014· •The granulometry of iron ore fines, used in sintering, has a great influence on sinter plant performance •Laboratory Experiments were conducted with different granulometry of iron ore fines to assess its influence on sinter quality and productivity •The upper size of the iron ore fines was reduced in each of the experiments
Mar 09, 2013· Fig 2 Material flow in a sinter plant The flexibility of the sintering process permits conversion of a variety of materials, including iron ore fines, captured dusts, ore concentrates, and other iron-bearing materials of small particle size (eg, mill scale) into a clinker-like agglomerate
Metallization will be better compared to lump ore There will be very much less fines in the product as against with lump ore No need for crushing and screening of iron ore and resultant fines disposal problem No losses in handling iron ore as PELLETS will not break during transport or handling 8
L Lu, O Ishiyama, in Iron Ore, 2015 145 Conclusions Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics
Hurdles remain “I am not saying anybody will take a wrecking ball to an integrated steel plant,” Sadoway says But he thinks an electrolytic smelter could avoid the need for a sinter plant to process iron ore, a coke oven to produce coke, and an oxygen furnace to remove excess carbon left over from the coke
Iron ore pelletizing systems Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets These are typically fed to a blast furnace or DRI plant as part of the process to make steel
