Oct 28, 2016· 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.
Today iron ore agglomeration is the largest tonnage application for sintering, with plants operating at up 20,000 metric tonnes per day. For example, Figure 2.14 is a picture of a modern agglomeration facility which incorporates off-gas capture to reduce environmental damage. In such a facility, the iron ore fines are mixed with fluxes, carbon fuel, and water.

Home » Technical » The Sintering Process of Iron Ore Fines heating of iron ore fines along with flux and coke fines or coal to produce a semimolten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace.
Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The 'recipe' for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests
IRON ORE CONSUMPTION IN BLAST FURNACE THROUGH STRUCTURAL MODIFICATION, TECHNOLOGY INTRODUCTION & PROCESS OPTIMIZATION Nitesh Kumar Nirala/V Manibharathi – Vedanta Iron Ore Business Abstract:- Iron ore and coke together account for about 99% of cost of input materials in Indian Pig Iron manufacturing plants. Moreover, sourcing iron ore and ...
All the above modifications have led to distinct improvements in equipment availability, increased roll life and a decrease in maintenance activities and improvement in crushed coke granulametry, ultimately resulting in improved productivity and quality of iron ore agglomeration …
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.
Iron ore is converted into various types of iron through several processes. ... further reducing the carbon content and adding other elements such as manganese and ... to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. ... to float sand and clay away, magnetic separation, pelletizing, and sintering.
As there can be significant variation in process requirements and sources of iron ore fines, testing is often an essential part of the development of a successful iron ore pelletizing operation. Different sources of iron ore will respond differently to agglomeration, and process requirements will subsequently vary.
Steele stiff extrusion is well suited for iron and steel waste oxide agglomeration, converting iron & steel mill by-products to feedstock. ... Our customer in West Bengal, India faced rising costs for iron ore and coke, the primary burden material for his blast furnaces.
Studiengesellschaft für Eisenerzaufbereitung (SGA) is a service centre for the process development of iron ore beneficiation, pelletizing, sintering as well as metallurgical testing of iron ore feedstock for blast furnace, direct reduction and steelmaking. Established in 1922, SGA is recognized world-wide for its facilities, expertise and know ...

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...
the endothermic reduction of iron oxide where coke reacts with adjacent iron ore particles and can be a major producer for CO emission. We aim at clarifying the criteria that divides the above-mentioned two routes of coke reaction and reducing CO emission by controlling granule structure and preventing the latter reaction.
Mar 09, 2013· The principle of sintering involves the heating of iron ore fines along with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace. It is basically an agglomeration process achieved through combustion.
Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. 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 called mixing and nodulizing drum.
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
CO 2 abatement in the iron and steel industry 5 Steel is basically an alloy consisting of iron, 0.02 to 2 wt% carbon, and small amounts of alloying elements, such as manganese, molybdenum, chromium or nickel. It has a wide range of properties that are largely determined by its chemical composition (carbon and other alloying elements). This has
