Depending upon the characteristics of the ore materials and the sintering conditions, daily average production rate of 22.5–44 tons/sq m/day of grate area is expected from the sinter machines. After the end of the travelling grate, the sinter passes through a spiked roll crusher and the hot screens to the sinter cooler.

The method of V–Ti iron ore blend optimization for sinter strength based on iron ore basic sintering characteristics is useful. (2) The BSCs of 5 kinds of V–Ti ores DB, HW, YT, JL and FH are good except LF. (3) The key reason that V–Ti sinter with a poor TI is the low LF, which caused the sinter with a large-pore structure.

The sintering process is used to agglomerate a mix of iron ore fines, return fines, fluxes, and coke, with a particle size of less than 10 mm, so that the resulting sinter, with a screened size of 5 mm to 30 mm, can withstand pressure and temperature conditions in the blast furnace (BF). The process of sintering of iron ore fines was primarily ...

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.

Granulation of the sinter mix is an important step in the iron ore sintering process. Several experiments were conducted at the pilot scale to achieve the PI objectives before the new technologies are developed or installed. Greater permeability of the sinter bed and thereby higher productivity is achieved with an enhanced granulation index.

The iron ore fines and concentrate cannot be directly utilized in blast furnace, and therefore, its agglomeration i.e. enlargement of particle size is necessary before it is used as feed for iron making. Sintering is one of the methods of agglomeration. All iron oxide bearing wastes and coke breeze is used for sintering purpose.
