Mar 15, 2015 · Sintering has been referred to as the art of burning a fuel mixed with ore under controlled conditions. It involves the heating of fine iron ore with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace.

the sinter. In the sintering process, the iron ore corresponds to the mixture of hematite, goethite and other gangue mineral typologies. However the goethite and gangue contents are relatively lower than the hematite, but the goethite + gangue to hematite ratio influences the reactivity during sintering.

Mar 22, 2021· Integrated steel plants usually use a large proportion of sinter as a source of iron in the blast furnace. Sintering is a thermal process used to agglomerate a base mix, which consists of iron ore fines, coke fines (which act as the sintering fuel) fluxes (usually limestone and dolomite fines) and recycled iron bearing waste.

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 ...
