nov 21, 2014 · sintering process is a generic term that is used to describe the process of agglomeration of a green mix of iron ores, fluxes and coke and plant solid wastes having a particle size of 10 mm so as to produce sinter which can withstand operating pressure and temperature conditions existing in a bf.
sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a
sinter is the primary feed material for making iron in a blast furnace. sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°c in a continuous belt-fed furnace.
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.
sintering of iron ore fines sintering is an agglomeration-technique for enlarging the iron ore particle size. the use of iron ore sinter in a modern day blast furnace has become common due to various advantages associated with it. the merits of sintering process are listed below in comparison to iron ore pellets: (i) the sintering process uses
sintering and pelletizing are two common agglomeration processes. in a bf, pig iron and blast furnace gas (bfg) is produced by reducing iron ore sinters and pellets with coal and coke. bfg is partly used for other processes within the iron and steelmaking plant, and the rest can be exported for power generation.

sintering tests can be conducted for several different purposes, for example, the assessment of the sintering behaviour of a particular iron ore fines, for production and quality control purposes at a sinter plant, or for research purposes concerned with the sintering process or sintering technology. from the results of these sintering tests

while the increase in such constituents is relatively slow over a long period, it has still caused problems for blast furnace operators. this paper attempts to clarify the role of different types of alumina present in iron ore fines and their effects on melt formation, sinter structure and sinter quality, as well as the sintering process itself.
the bf-bof steelmaking process often includes pelletizing and sintering of iron ore, and coking of metallurgical coal as preliminary processes for iron and steelmaking. producing one tonne of steel through the bf-bof steelmaking route emits around 2.2 tonnes of co 2 / tonne crude steel  and requires roughly 20.8 gj / tonne crude steel  of

the iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. however, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. the fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. this chapter shows the status of the pelletizing process
bf operation, for example, increase of rar and slag ratio. depletion of high grade iron ore deposits is moving us to use concentrates in sintering process. through magnetite concentration deteriorates reducibility because of high feo content in sinter product. such situation makes it to promote oxidation of magnetite iron ore during sintering
addition to the blast furnace (bf) process, to the sintering of iron ore and iron ore pelletizing are the main areas. the relative high mgo content and sio 2 content are regarded as beneficial, as well as the relatively low loi (loss on ignition) of olivine, with respect to dolomite and limestone.

sinter made from magnetic concentrates is no longer massive but open and cellular in structure, and deserves a preference for furnace use as compared with natural ores. silicate of iron, which composes heating furnace cinder and is difficult to reduce in the blast furnace, does not occur in the sinter produced by the continuous down-draft method.
original purpose of the process is to agglomerate fine into lump burdens for blast furnace since conditions, e.g., kinds of and used fluxing materials, and pregranulation processes, strongly affect the metallurgical properties of the produced many researches and developments on the process have been made in order to achieve a stable and efficient
