would otherwise occur if the iron ore coke and limestone were fed into the blast furnace in a loose or powdered state At Scunthorpe there are two sinter lines referred to as strands Each strand is 4 2 metres wide x 0 55 metres deep and 72 0 metres long and processes 7 000 tonnes per day of sinter Each strand has a sinter hood Like other sintering processes iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates namely sinter between 5 and 50 mm particle size which possess the physical and metallurgical characteristics and gas permeability required for

Iron Ore For Blast Furnace

Use Of Iron Ore Pellets In Blast Furnace Burden Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a pelletizer and

EFFICIENT AND ENVIRONMENTALLY FRIENDLY SMELTING REDUCTION A VAI Ironmaking Technology primetals YOUR CHALLENGE The conventional blast furnace route is too costly and energy-intensive to keep pace with dynamic market changes where even short- and medium-term fluctuations show their dramatic impact on iron production The need to use coke and sinter

L Lu O Ishiyama in Iron Ore 2015 14 5 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

In this pot grate test the material contained in the sinter pot passes through different process stages as the material would on a sinter belt Chemical composition and the physical properties of the produced test sinter are measured by means of standardized ISO-procedures and the results can then be applied into the real plant

The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal mechanical physical and chemical) to be fed to the blast furnace The process has been widely studied and researched in the iron and steelmaking industry to know the best parameters that allow one to obtain the best sinter quality The present article reviews the

Ironmaking 101

Ironmaking Blast Furnace Iron is made by reacting iron ore (iron oxide and impurities) coke (a reductant) and limestone (CaCO 3) in a blast furnace Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities

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 raw material is rolled into a ball then fired in a kiln to sinter the particles into a hard sphere The configuration of iron ore pellets as packed spheres in the blast furnace al lows air to flow between the pellets decreasing the resistance to the air that f lows up through the layers of material during the smelting The configuration

Iron Ore Sintering For Blast Furnace In theory any ore containing iron or iron compound can be called iron ore used for steel making processere we introduce some iron ore magnetite is an iron ore the main ingredients is fe3o4he color is dark gray containing fe72 o 27agnetic method can be used during beneficiation in steel making by using nickel smelter

Iron Ore Processing for the Blast Furnace blast furnace process The iron ore concentrate is now mixed and ready for the pelletizing process Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets in much the same manner that one rolls a snowball to make a pellet about the size

In the Blast Furnaces (BF) liquid iron (popularly termed as 'Hot Metal') is produced by the process of reduction at high temperature from raw materials like iron ore base mix sinter pellet coke fluxes (limestone quartzite Dolomite Mn-ore) etc also pre heated air blast / O 2 In blast furnace the process is

Iron Ore Sintering For Blast Furnace Blast furnaces produce iron by exposing iron ore iron pellets and sinter to high temperatures and carbon monoxide a reducing agent Coke is the primary fuel although it is often augmented by injected auxiliary fuels Preheated air from the hotblast stoves is also injected into the furnace Get Price

Blast furnace

Pig iron is an intermediate product of the iron industry also known as crude iron which is obtained by smelting iron ore in a blast furnace In the process of smelting inorganic chlorides fluorides (see fluorite) limestone and other materials are designated as fluxes when added to the contents of a smelting furnace or a cupola for the purpose of purging the metal of
