Agglomeration of iron ores, London, Heinemann Educational Books Ltd. [Google Scholar]) is the most popular method used around the world to convert fine ores into a coarse agglomerate. For many furnaces, the main iron-bearing material is sinter and usage levels of 80%, the others being pellets and selected lump (>6·3 mm) iron ores, are common.
Iron-rich (65 to 70 pct total Fe) mill scale generated during processing by steel mills can be recycled by using it as a ferrous raw material in the sintering process. The effect of mill scale addition on the phase formation of sintered specimens from an industrial sinter blend containing 0 to 15 wt pct mill scale was examined, and ...
Profitability Solutions: Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. Sinter strength plays an important role in deciding PCI rate in the blast furnaces.
Iron ore sinter, a burden material for blast furnaces, is obtained by complex processes involving partial smelting of sinter mixture components under conditions of solid fuel combustion in the sintered bed.
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.
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). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
sintering iron ore process Theory and Practice of Sintering of Iron ore ispatguru. 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 …

Mill scale is a valuable ferrous raw material, containing 65 to 70 pct iron [ 2] and is often recycled through the sintering process. [ 3] During iron ore sintering, iron ore fines are mixed with limestone and coke breeze. The combustion of coke breeze supplies the necessary heat to achieve partial melting and reaction of the raw materials.
