Substitution of Charcoal for Coke Breeze in Iron …
previous studies, 7,9) substitution of charcoal for coke breeze was reported to result in higher sintering productivity, but with much higher fuel rates and weaker sinter .
Index Terms— coke breeze, charcoal, sintering process ...
breeze used as a fuel in iron ore sintering by palmstone charc oal could be achieved without deteriorating the sintering process or decreasing the metallurgical properties of produced sinters; when about one third of the coke breeze was replaced by char-coal. Shalabi et al [9] indicated that when coke breeze was partial-ly replaced by 1.5 equivalent amount of stone stone energy-wise, the amount ...
Theory and Practice of Sintering of Iron ore – …
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 particular form of agglomerate. It consists of heating the sinter mix with a particle size of less than 10 mm to ...
(PDF) Iron Ore Sintering: Process - ResearchGate
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).
What Is Iron Ore Sintering? (with pictures)
02.04.2020 · Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the particles congeal. Once congealed into an agglomerate, the ore is again crushed. Screening ensures non-iron particles are removed and the remaining iron particles average between 15 and 30 …
Recycling of Blast Furnace Dust in the Iron Ore Sintering ...
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 the literature on the carbon replacement factor of fine-grained blast furnace ...
Sintering: A Step Between Mining Iron Ore and …
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.
The Sintering Process of Iron Ore Fines – IspatGuru
Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product of a suitable stone composition, quality ...
Experimental study of commercial charcoal as …
According to the above investigation, commercial charcoal is a wise choice for alternative fuel to partially replace coke breeze in iron ore sintering. Charcoal has much larger specific surface area and higher intrinsic reactivity than those of coke breeze, which is helpful to increase sintering speed.

Effects of anthracite replacing coke breeze on …
05.06.2008 · Anthracite coal as fuel for iron ore sintering is compared with coke breeze. Anthracite is lower in porosity, higher in density, and slower in combustion rate. With higher proportion of anthracite in fuel, permeability of sinter bed tends to decrease resulting in lower sinter productivity. Higher fuel rate with more replacement of coke breeze by anthracite is ascribed to the lower density of ...
