Jan 01, 2012· Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites.
Sep 30, 2012· Compared with sintered ore, pellets have a higher iron- and a lower gang-content, and pelletizing is suitable for treating the very fine ore that will predominate in the future.
Apr 19, 2017· In sinter,there are 3 types. 1 . Acidic sinter 2.fluxed sinter 3.super fluxed sinter 1.In acidic sinter basicity is less than one. 2.fluxed sinter basicity=1 3.super fluxed sinter basicity more than 1. If we charge acidic sinter,we wanted to add...
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 ...
In a sinter plant, iron ore and fluxes are agglomerated as a suitable feedstock for the blast furnace. Fig. 1 shows a schematic diagram of the sintering process. The sintering process is energy intensive and produces a considerable amount of CO 2 from the combustion and calcination of coke breeze and carbonates, respectively.
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and
Theory and practice of the sintering process ... of reactions that forms the sinter cake to be loaded into the blast furnace to produce pig iron. ... on the mechanism of iron ore sintering process ...
WHAT IS AN INDURATING FURNACE Indurating Furnacesare circular shaped furnaces like a Rotary Kiln and form a key part of one of the process routes for preparing iron ore fines for use in blast furnaces, and are specifically used to produce iron ore pellets. Raw or "green" pellets need to be baked to give them sufficient mechanical strength to
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.
of using high grade ore to the performance of Sintering and Blast Furnace processes in terms of energy savings, CO 2 emissions, and logistic benefits to the mills in the region. Keywords: high grade iron ore, sinter, blast furnace, Brazilian fines, pot sinter, Alumina * Msc. Metallurgical Engineer - R&D Technical marketing – Vale S.A. - Brasil
PDF | Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke). The purpose of ...
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
location and extent of cohesive zone in the blast furnace as related to the degree of reduction of iron ore pellets/iron ore this thesis is submitted in the partial fullfillment of the requiremnt for the degree of bachelor of technology in metallurgical and materials engineering by abhimanyu kadiyan (roll no. 109mm0656) & aneesh singhal
Technology has been developed for the production of fluxed local sinter and pellets with residual carbon for blast-furnace use. The new products have better metallurgical characteristics than... Improved iron-ore sinter for blast furnaces | SpringerLink
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.
HOW A BLAST FURNACE WORKS Introduction 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 bottom.
In iron ore sinter plants blast furnace dust and other fine-grained residues which are rich in iron or car-bon content are recycled. The carbon contained in the blast furnace dust can be used to replace coke breeze which is added to the charge as fuel for the sintering process. However, there is no information in
Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. Sinter strength plays an important role in deciding PCI rate in the blast furnaces.
Oct 04, 2016· Blast furnace Working animation - Extraction of iron metallurgy of iron. Class 12 Iron and steel production from iron oxides or iron ores. General principles and processes Isolation of Elements ...
