which includes sintering and blast furnace processes, and only the sintering process represents around 20 of this amount1,5. Therefore, sintering and blast furnace processes offer good opportunities to decrease the CO 2 emissions since mall decreasing of the coke breeze consumption and bonding agent used in iron ore sintering process
Sintering A Step Between Mining Iron Ore and Steelmaking. The remaining 2 of domestic iron ore was produced for non-steel end uses. Seven open-pit iron ore mines each with associated concentration and pelletizing plants, and three iron metallic plantsone direct-reduced iron DRI plant and two hot-briquetted iron HBI plants operated during the year to supply steelmaking raw materials.
FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in
High grade iron ore less than 10 of the total reserves. ROM iron ore with Fe less than 58 60 discarded as waste. After beneficiation iron ore availability can improve by about 50. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative 1.

Mar 17, 202001833260 of steel is made via the integrated route, which produces virgin steel from iron ore. Iron, in the form of sinter, is reduced in the presence of coke in a blast furnace BF, and then converted into crude steel in a basic oxygen furnace BOF. 40 of steel is made through the recycling route, where scrap steel is rep . Process heat overview
Jul 15, 2014018332Sinter 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.
The main objective of this project is to maximize the available Low Grade high alumina Iron Ore fines at economical price in Pig iron manufacturing process through better process optimization amp thereby achieving lowest cost of production.. 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.

sinter pot test. The VIU Value In Use team at Kumba Iron Ore routinely uses sinter pot tests to evaluate new sinter raw materials, primarily in terms of production rate, coke consumption, and product sinter physical properties. Optimum sinter blends can be investigated as well as the impact of changes in sinter
In work carried out in a sinter pot loaded with 65 kg of ore mixes with different alumina contents, an increase in the alumina content from 2 to 5.5 raised the sinter RI from 58 to 64 9. 2.1.3. MgO sinter MgO provides for an optimum blast furnace slag condition in terms of

May 07, 2015018332rameters. Among raw materials due to its major quantity, the iron ore plays the most significant role in sintering and hence the iron ore should have better metallurgical properties like high reducibility gt70, low degradation index, high softening and melt-down characteristics. Sintering process is extremely complex due to very short time.
