use of green pellets in sinter making ... future of the iron making processes that use sinter and pellets, mainly the Blast furnace and DR process. The future of these processes in turn depends upon steel production and consumption, which have been on an upward trend. Environmental interest Commitments to minimise CO2 emission ...
The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier. A high quality sinter has high reducability, which reduces the intensity of blast furnace ...
If above expected quality sinter will be replaced with iron ore in blast furnace, maximum ratio (80 85 %) of sinter can be used safely. Production cost of the sinter has to be considered while using the sinter in blast furnace which is depending on the cost of raw materials for sinter making.
Sintering, Iron and Steel Making Troogh Blast Furnace and Sinter Making, Iron ores, Iron ore Technological Changes in Blast Furnace Iron Making in India since Last Few Decades India as a 4th steel producer in the world has resulted due to adaptation of new technologies in the field of iron and steel making since from the last few decades.
Currently there are two major ironmaking technologies: reduction of iron in the blast furnace, and secondary production of iron from recycled scrap in electric arc furnaces. The blast furnace traditionally relies on the use of coke as a reductant and to provide mechanical strength and porosity in the blast furnace charge.

of phenomena in the lower part of a blast furnace (including the behavior of particulate substances), quality control of sinter and coke such as a sintering method for lowering SiO 2 content and blast furnace evaluation technology, etc.), (3) Use of plastics as the alternative energy source for blast furnaces and coke ovens,
In traditional blast furnace iron making, the iron ore is fed to the blast furnace in one of three common forms: Lump, pellets or sinter. All of which are designed (in conjunction with coke) to maintain a porous feed bed in the blast furnace and thus facilitate rapid and uniform reduction of the iron ore (iron oxide) to iron .

Aug 04, 2011· 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 .
At present most of the steel plants in the world are reusing HMDS Slag as a flux instead of limestone in sinter making. At JSW Steel Limited steel making slag is completely dumped or used for ground filling after crushing. Based on the earlier trials at JSW steel making slag is being used up to 40 kg/t in COREX and 50 kg/t in blast furnace.
Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent
