Iron ore sinter plants are energy-intensive components of integrated iron and steel production (see Table 1), where the iron ore fines (<5 mm) are converted into larger (>5 mm) lump sinter cakes with greater gas permeability, which are the most important burden materials for iron making in blast furnaces (BFs) [7].The main process is shown …

Wear Resistant | Sinter Production

Iron ore is the key raw material for making iron and steel. However, it cannot be used in its unprocessed state. Sinter production is a thermal process that converts the mixture of agglomeration iron ore fines, coke, and fluxes into a sinter—the primary feed material of suitable composition and granularity for the induction blast furnace.

Iron ore

The iron content of the CSN Mining sinter feed usually exceeds 63%. Pellet Feed (0.150mm): The very fine iron ore product is obtained after the flotation process. In order to be used in the steelmaking process, it should be pelletized. At smaller percentages, it can also be blended into sinter feed and used at sintering units.

Basics of Iron Ore Sintering

The sinters produced in pot grate furnace were dropped three times from a height of 2 m onto a steel plate and + 5.6 mm fraction is taken as usable sinter i.e. yield and the balance as return sinter. The material for hearth layer is drawn from the usable sinter. 3.1 Shatter Test. 20 kg of 10–40 mm size sinter is taken for shatter test.
