Effects of anthracite replacing coke breeze on iron ore ...
Abstract 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.
Combustion behavior of granulated coke breeze in iron ore ...
In iron ore sintering, coke breeze particles will oxidize and release a large amount of heat, as shown by Eq. . Meanwhile, the coke breeze serves as a reducing agent, having various reactions with its surrounding materials, such as iron ore, in the granules.
What Is Iron Ore Sintering? (with pictures)
Oct 27, 2019 · Specifically, iron ore sintering requires the use of fine ore, produced by crushing high-grade iron ore into particles only a few millimeters in diameter. 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.
Substitution of Charcoal for Coke Breeze in Iron Ore Sintering
It is unclear why the same ore blend generates weaker sinter when charcoal is used to replace coke breeze. In the present study, the apparent and packing densities of green granules were found to decrease considerably as the substitution rate of charcoal increased.
Sintering: A Step Between Mining Iron Ore and Steelmaking
According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
(PDF) Effect of coke size on iron ore sintering
This stone investigated the combustion behavior of coke breeze granulated with other raw materials for iron ore sintering in a broad temperature range up to 1350 °C in air and sintering flue gas ...
Substitution of Charcoal for Coke Breeze in Iron Ore Sintering
The substitution of charcoal as an alternative fuel to coke breeze in a simulated Japanese Steel Mills (JSM) sinter blend was investigated. Compared with coke breeze, higher mix moisture contents were required for the sinter mixture containing charcoal to achieve optimum granulation.
Iron Ore Sinter – IspatGuru
Jul 15, 2014 · Iron ore sinter or simply called sinter is usually the major component of a blast furnace iron bearing burden material. Sinter normally consists of various mineral phases produced by sintering of iron ore fines with fluxes, metallurgical wastes and a solid fuel. Coke breeze is normally used as fuel in the sinter mix since it supplies necessary heat energy for sintering of sinter mix. Fig 1 shows a piece of sinter.
Experimental study of commercial charcoal as alternative ...
Oct 01, 2016 · Coke breeze and anthracite are the traditional heat suppliers to iron and steel industry while global warming issue has been a focus of concern. Using biomass for partial or complete replacement of coke breeze in the iron ore sintering process is an attractive technique for reducing emissions of greenhouse gas and gaseous pollutants.

Optimisation of FeO in iron ore sinter at JSW Steel ...
Mar 24, 2017 · Coke breeze is the most common fuel used in sintering, and its usage depends on the alumina content and fineness of the sinter mix. The coke breeze consumption in the JSW Steel Limited sinter plant was high compared to many other sinter plants in the world, and as there was a local shortage, optimisation in the sinter plants was necessary.
Iron processing - Ores | Britannica
Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger ones, and then …
Granulation of Coke Breeze Fine for Using in the Sintering ...
Coke breeze act essentially as high carbon content, heat content and clean burning fuel is used primarily in iron ore sintering processes. As a result of growth of the iron and steel industry all over the world, prime coking coal with adequate properties that yield metallurgical coke is becoming increasingly difficult
Corrosionpedia - What is a Coal Coke Breeze? - Definition ...
Coal coke breeze is a common backfill material used in cathodic protection. It is a type 1 carbonaceous backfill material. Coal coke breeze backfill has low resistivity and low ash content, and may be treated by the addition of 10% (by weight) commercial grade slaked lime. The fuel used in the iron ore sintering processes is coke breeze.
